Associations between some soft markers and adverse pregnancy outcomes including intrauterine fetal death, preterm birth, fetal growth restriction, and congenital infection have been reported in euploidy fetuses. presented in this activity is not meant to serve as a guideline for patient management. J Ultrasound Med. The doctor told me the UTD/kidney had resolved and was now normal as expected but the heart calcification was still there. However, at my 20 week anatomy ultrasound the identified 2 "soft markers" for DS. 2005-2023Everyday Health, Inc., a Ziff Davis company. Trisomy 21, 18, 13 or an unbalanced autosomal structural abnormality are associated with relative short FL (risk 1:123; 95% CI, 79192) [31]. I had the NIPT @ 12 weeks and everything came back as normal 99% negative for Down Syndrome. That software may be: Adobe Flash, Apple QuickTime, Adobe Acrobat, Microsoft PowerPoint, Windows Media Player, or Real Networks Real One Player. "Is an EIF and a CPC found together at the same time considered isolated findings, since EIF is more linked to trisomy 21 (Down syndrome) and . I wanted the amnio for confirmation and am waiting, FISH results should be back tomorrow or Tuesday. Ultrasound Obstet Gynecol. Because fetal aneuploidy can affect any pregnancy, all pregnant women should be counseled and offered aneuploidy screening regardless of age. The views expressed in community are solely the opinions of participants, and do not reflect those of What to Expect. Keep me updated! Russo, ML, and Blakemore, KJ (2014). Copyright 2020 by the American Academy of Family Physicians. Soft markers were originally introduced to prenatal ultrasonography to Soft Markers Identied on Detailed Ultrasound Several markers identi!ed on second-trimester ultrasound examination are associated with increased . Intracardiac echogenic foci have no hemodynamic significance in the fetus. Rodriguez, R, Herrero, B, and Bartha, JL (2013). Pediatr Cardiol. The results came back negative so they pretty much brushed it off. Please keep me posted. Keep in mind that an ultrasound done around the 20 th week often has signs of soft markers, or around 1 in 30. nephrology follow-up is needed. These stories give me hope! think twice before sharing personal details, foster a friendly and supportive environment, remove fake accounts, spam and misinformation, delete posts that violate our community guidelines, reviewed by our medical review board and team of experts. and our These activities will be marked as such and will provide links to the required software. [30], isolated shorted HL and FL in second trimester demonstrated higher rates of preterm delivery and preeclampsia. It is performed any time after 15 weeks' gestation; earlier amniocentesis has higher complication rates.44 Both tests carry a risk of pregnancy loss, with an estimated risk of one in 455 for chorionic villus sampling and one in 900 for amniocentesis.1,45 The laboratory tests performed depend on the indication for the diagnostic procedure but may include karyotyping, chromosomal microarray, or fluorescent in situ hybridization. The OBG Project planners and others have nothing to disclose. Therefore, karyotyping should be offered when thickened NF is observed [10]. Prenat Diagn. Prenatal screening aims to detect the most common forms of aneuploidy compatible with survival beyond early embryologic development into viability. Just looking for stories/to talk to someone on a more human level, Just a question, if you did find out there's something wrong, what would you do about it? The genetic counselor said she was most concerned about Down syndrome, so thats definitely encouraging now that that is ruled out. http://creativecommons.org/licenses/by-nc/4.0/, Detail evaluation for other markers of aneuploidy, Evaluation of fetal heart, consider fetal echocardiography, 32-week ultrasound to assess growth and to rule out certain skeletal dysplasia, Undergo targeted anatomical survey (level II ultrasound). and isolated choroid plexus cysts, we recommend no further aneuploidy I wanted the amnio for confirmation and am waiting, FISH results should be back tomorrow or Tuesday. After normal screening for the aneuploidy in first trimester, there are no uniform recommendations regarding when to disregard or put on clinical significance in isolated soft markers. Prenat Diagn. Diagnostic tests following a positive screening result include chorionic villus sampling performed between 10 and 13 weeks' gestation or amniocentesis performed after 15 weeks' gestation. My FISH results came back negative! growth restriction, or additional soft marker following a detailed This paper will review recent literatures about the most common second trimester sonographic soft markers and propose a simple clinical guideline for management of specific soft markers in pregnancies (Table 1) [3,6,10,1236]. This educational activity may contain discussion of published and/or investigational uses of agents that are not indicated by the FDA. third-trimester ultrasound examination for reassessment and evaluation Diagnostic testing should not be recommended to patients with an isolated soft marker in the setting of a negative NIPT result [9]. 2018 Korean Society of Medical Genetics and Genomics. Eur J Obstet Gynecol Reprod Biol. aneuploidy solely for the evaluation of an isolated soft marker Multiple soft markers were associated with an increased risk of congenital anomalies and preterm birth [3,6,1215]. Furthermore, more studies are needed to establish standard guidelines and to facilitate the application of soft markers to the clinical practice in Koreans. The impact of isolated single umbilical artery on labor and delivery outcome. First-trimester combined screening performed between 10 and 13 weeks' gestation detects 82% to 87% of trisomy 21 (Down syndrome) cases. Upon registering and successfully completing the test with a score of 100% and the activity evaluation, your certificate will be made available immediately. 2005-2023Everyday Health, Inc., a Ziff Davis company. A measurement of 1012 mm is commonly referred to as mild VM, while measurement of 1215 and >15 mm are defined as moderate and severe VM. Please take long walks and do breathing exercises and know that eventually this will all be confirmed and resolved. A Group Leader is a What to Expect community member who has been selected by our staff to help maintain a positive, supportive tone within a group. Use of the soft markers may increase the positive predictive value in patients with first trimester combined screening (FTS) (combination of maternal age, biochemical screening tests of free -hcg and PAPP-A, and nuchal translucency) [7]. Find advice, support and good company (and some stuff just for fun). Shortened humerus and femur are defined as bone length below the 5th percentile for gestational age [30]. It seems to me every option is a good option in this case. Hi everyone! A Group Owner is a member that has initiated the creation of a group to connect with other members to share their journey through the same pregnancy & baby stages. Fetal fraction was 10%. What to Expect supports Group Black and its mission to increase greater diversity in media voices and media ownership. In cases of isolated IEF in euploid fetuses there is no evidence of an altered cardiac function and a detailed echocardiogram is not recommended as long as the second trimester scan is normal [42]. options. aneuploidy screening with cell-free DNA or quad screen if cell-free DNA Semin Perinatol. The PIM planners and others have nothing to disclose. Thank you so much to anyone who answers and to those who like me read these posts to feel less lonely. How did everything turn out for you?! The American College of Studies advocate serial fetal growth assessment when isolated echogenic bowel was detected at the first and the second trimester because it is associated with FGR and increase in intrauterine fetal demise (relative risk [RR] 1.6 for FGR and 8.6 for intrauterine fetal demise). It appears you don't have enough CME Hours to take this Post-Test. Catania, VD, Taddei, A, Pellegrino, M, De Marco, EA, Merli, L, and Manzoni, C (2017). to estimate the probability of trisomy 21 and a discussion of options Isolated IEF are associated with an increased risk of Down syndrome, with likelihood ratios generally ranging from 1.5 to 5.0 [26]. The absence of a fetal nasal bone warrants a detailed evaluation of fetal anatomy. I am anxious, terrified, confused, just hoping for good news. Isolated prenatal choroid plexus cysts do not affect child development. Hope . [16], the fetuses with isolated unilateral VM had 0% chromosomal abnormalities, 8% congenital infection, and in about 5% of fetuses, there is progression of VM during the course of the pregnancy. The overall prognosis of VM strongly depends on both the extent of enlargement and/or the presence of other abnormal findings or structural malformations. Two-third of them was detected during the first and the second trimesters with the prevalence ranging from 0.2 to 1.8%. Most cases (95%) had a single marker, 4% had two markers, and 1% had three or more markers when soft markers were first identified [10]. It has been estimated that between 0.5 to 2.8% of euploid fetuses will have images consistent with delayed ossification of the nasal bone in either first-or second trimester sonography [23]. No other abnormalities or concerns were found. Group Leaders communicate with staff moderators and escalate potential violations for review, but they dont moderate discussions. pregnant people with no previous aneuploidy screening and isolated I know NIPT is only a screening test so Im very worried at this point and honestly feel trapped because I am so far along. just got negative FISH results too!! Short HL and FL may be an early sign of placental dysfunction and warrant increased antenatal surveillance with repeated sonography for growth assessment and frequent blood pressure measurements [32]. Single Umbilical Artery, or the Two Vessel Cord: What Does it Mean? Anyone else have neg nipt but still found multiple soft markers on anatomy scan? Postgraduate Institute for Medicine (PIM) requires faculty, planners, and others in control of educational content to disclose all their financial relationships with ineligible companies. methods refers to all maternal screening strategies, including Search dates: March 2019 and January 2020. The potential for a fetus to be affected by genetic disorders that are not evaluated by the screening or diagnostic test should also be reviewed. They told me because my NIPT was negative that the chance of the reasoning behind the thickened nuchal fold being down syndrome is 1 in 10,000 but the chance of miscarriage after the amniocentesis is 1 in 1,000. I decided to have the microarray but am very nervous about getting inconclusive results? Women with positive aneuploidy screening results should be offered referral to maternal fetal medicine and genetic counseling to discuss invasive diagnostic testing with chorionic villus sampling or amniocentesis. The results came back negative so they pretty much brushed it off. Antenatally detected urinary tract abnormalities: more detection but less action. pregnant people with negative serum or cell-free DNA screening results Breathe and you will get through this!! If amnio results are negative, should I push for the microarray? obstetrical ultrasound examination. If youve had it done how did it go? I know I wont be able to relax until I get all these results back, so I know exactly how you feel. The TRIP database was queried with similar terms. CME Included, Please log in to ObGFirst to access the 2T US Atlas. Gupta, G, Aggarwal, S, and Phadke, SR (2010). that has been identified in the absence of any fetal structural anomaly, J Clin Ultrasound. For fetuses with urinary tract dilation choroid plexus cysts, we recommend counseling to estimate the Prenat Diagn. A retrospective analysis demonstrated associations between abnormal quad screening markers and adverse pregnancy outcomes.13,22 Women with abnormal quad screening results without subsequent evidence of aneuploidy or neural tube defect may have increased risk of adverse pregnancy outcomes, including preterm birth, fetal growth restriction, preeclampsia, and fetal loss. Also, looking for soft markers of trisomy 21, should not be performed in women with a normal NIPT result due to its high false-positive rate and poor positive predictive value [11]. A2-3, we recommend an individualized follow-up ultrasound assessment My OB is the go to high risk doctor in our city and he said the test is so accurate that he isnt concerned about the markers he saw anymore. SUMMARY: Soft markers are ultrasound findings that do not represent a structural anomaly, may be a normal variant, but have been associated with increased risk for fetal aneuploidy. It might be clear and give you peace of mind, or it will give you clear information and you can move forward with certainty. Routine karyotyping of all pregnancies with these markers would have major implications, both in terms of miscarriage and in economic costs. Norton, ME, Biggio, JR, Kuller, JA, Blackwell, SC, and Society for Maternal-Fetal Medicine (SMFM) (2017). probability of trisomy 18 and a discussion of options for noninvasive Ultrasound Obstet Gynecol. J Ultrasound Med. It is essential . Pagani, G, Thilaganathan, B, and Prefumo, F (2014). It is an uncommon but recognised phenomenon and is known to result in false negative non-invasive prenatal testing (NIPT). The prevalence of pyelectasis varies from 0.1 to 2.4% in low risk populations [1]. With rapid implementation of NIPT as a new method of prenatal testing for Down syndrome or other common aneuploidies in the first trimester, it became easier to deal with soft markers. Therefore, a follow-up ultrasound at 32 weeks of gestation to rule out persistent pyelectasis should be performed. Some studies have shown a higher risk of SGA, preterm birth, pregnancy-induced hypertension, admission to the neonatal intensive care unit, and perinatal mortality [33,35]. If you wish to receive acknowledgment for completing this activity, please complete the test and evaluation. However, case reports have described an absent fetal nasal bone in B-cell immunodeficiency, cri du chat (5p) syndrome, and partial trisomy 20q. Create an account or log in to participate. CMV, cytomegalovirus; TORCH, toxoplasmosis, rubella, cytomegalovirus and herpes simplex; UPJ, ureteropelvic junction; SGA, small for gestational age. and consideration of weekly antenatal fetal surveillance beginning at 36 Fetal Diagn Ther. The baby has a subclavian artery going in a different position and this can be a marker for down syndrome. following a negative serum or cell-free DNA screening result (GRADE 1B); bowel, urinary tract dilation, or shortened humerus, femur, or both, we BMC Pregnancy Childbirth. The present article aims to review recent literatures about the clinical significance of soft markers after normal first trimester combined screening or noninvasive prenatal testing, and propose a simple clinical summary for management of specific soft markers in pregnancies. I am in a similar situation right now and so worried! It is used to screen for Trisomy 21, 18 and 13 as well as sex chromosome aneuploidy. cell-free DNA or quad screen if cell-free DNA is unavailable or Patients with intermediate risk are offered second-trimester quad screening to refine risk estimates. Considering these cases, microarray studies could be performed in addition to a fetal karyotype when an absent fetal nasal bone occurs with additional sonographic anomalies [24]. Also, looking for soft markers of trisomy 21, should not be performed in women with a normal NIPT result due to its high false-positive rate and poor positive predictive value [11]. thickened nuchal fold or isolated absent or hypoplastic nasal bone, we In this low risk population, soft markers were found in 5.9% of fetuses at second trimester ultrasound; markers were isolated in 5.1%, multiple in 0.7%, and combined with anomalies in 0.1% [1]. The purpose of this document is to discuss the The Society for Maternal-Fetal Medicine I had a 7.5 mm nuchal fold at 7.5 weeks and the mfm I spoke with seemed very concerned. It is essential to provide information to the parents about the observed soft markers and its potential impact on prenatal and postnatal life. I decided to have the microarray but am very nervous about getting inconclusive results?! Feel free to buy additional CME hours or upgrade your current CME subscription plan, You are now leaving the ObG website and on your way to PRIORITY at UCSF, an independent website. Looking for anyone with a similar experience- at 10 weeks my NIPT results came back negative for trisomy 21, 13, and 18, and we were told we were having a healthy baby BOY. Prevalence, characteristics and perinatal outcome of fetal ventriculomegaly in 29,000 pregnancies followed at a single institution. One in every 23 pregnancies with a NF measurement 5 mm had a congenital heart disease (sensitivity=3.3%, specificity=99.6%). Battarbee, AN, Palatnik, A, Ernst, LM, and Grobman, WA (2015). people with negative serum screening results and isolated thickened Hey mamas,I wanted to share my story in hopes that it may help others out there in a similar situation. Curr Probl Diagn Radiol. If you feel a message or content violates these standards and would like to request its removal please submit the following information and our moderating team will respond shortly. I've been seeing a few posts on soft markers so I'm hoping this may make you feel a bit more at ease about it. DiPietro, JA, Cristofalo, EA, Voegtline, KM, and Crino, J (2011). for fetuses with an isolated single umbilical artery, we recommend no Im waiting for my amnio results to come back now, and Im so worried. Renal Pyelectasis on Prenatal Ultrasound Next Steps? Use of this site is subject to our terms of use and privacy policy.

I hope you get good results . Your post will be hidden and deleted by moderators. This is a question for a genetic counsellor, but I heard that its more likely to have a false positive. First- and second-trimester serum screening or first-trimester nuchal translucency alone can be used to screen women with twin pregnancies for aneuploidy, although detection rates are lower. First trimester screening for trisomy 21 based on maternal age and fetal nuchal translucency detects about 70% of affected fetuses for a 3% false positive rate and with additional assessment of nasal bone, the detection rate increases to about 80% with the same false positive rate [40]. In stepwise sequential screening, first-trimester combined screening (PAPP-A, hCG, and nuchal translucency) results are given to the patient if positive so that she may be offered early invasive diagnostic testing. https://www.psychosocialresearchgroupunsw.org/decision-aids.html, Systematic reviews and meta-analyses of high-quality diagnostic accuracy studies; NIPT performs similarly in high- and low-risk populations, although positive predictive values are lower in low-risk populations, Meta-analysis of diagnostic accuracy studies with limitations; detection rates are lower in twin pregnancies, Expert consensus guidelines; no screening test, including cell-free DNA, is considered diagnostic. weeks of gestation to determine if postnatal pediatric urology or Low risk NIPT but soft marker in ultrasound : Hi ladies I had the Harmoney test done at 11 weeks and it came back 1 in 10,000 so low risk however At my recent ultrasound a soft marker was found. an educational tool, January 2022. Were only 21 and have a 15 month old too. I will tag your post with POST FLAIR on which you can click and find similar posts about your result. Also, asymmetric pattern of VM is a potential risk factor for anomalies of neuropsychological development [18]. An Essential Evidence Plus summary of patient-oriented evidence that matters was reviewed. Its prevalence is 1 to 6 per 1,000 [3]. Theyre saying 2-3 weeks. Negative NIPT but 2 soft markers seen on ultrasound I am anxious, terrified, confused, just hoping for good news. What is the importance of second-trimester soft markers for trisomy 21 after an 11- to 14-week aneuploidy screening scan?. soft markers has shifted. If no screening has been First one is a "bright spot" on the heart and the second is one slightly enlarged kidney. In the study of Kaijomaa et al. Although some soft markers can be occurred in a fetus as 2 normal variants, because of increased incidence in abnormal situations such as chromosomal and congenital abnormalities and. The possible etiology is not yet fully understood, but it may be of placental origin. She didnt give us much info and said I could see a genetic counselor. 2 soft markers at 20 weeks but negative NIPT. First-trimester combined screening consists of ultrasound testing of fetal nuchal translucency, maternal serum pregnancy-associated plasma protein A (PAPP-A) levels, and free or total human chorionic gonadotropin (hCG) levels obtained between 10 0/7 and 13 6/7 weeks' gestation.1,18,19 Nuchal translucency alone should not be used to screen for trisomy 21 in singleton pregnancies. It is important to understand the characteristics of each soft marker to prevent unnecessary karyotyping and to perform necessary karyotyping. For example, the risk of a woman giving birth to a live newborn with trisomy 21 (Down syndrome) increases from one in 1,480 at 20 years of age to one in 85 at 40 years of age.1 Although the overall birth rate in the United States has declined, the portion of first births to women older than 30 years increased from 23.9% in 2000 to 30.2% in 2014.4,5 Because fetal aneuploidy can affect any pregnancy, all pregnant women should be counseled and offered aneuploidy screening regardless of age.1,6,7. Previous studies reported isolated echogenic bowel was associated with an increased risk of congenital anomalies, and preterm birth. Uh what?! Fetal Diagn Ther. Were worried about what the other results/problems could be but were also worried about the risks of doing the amniocentesis. Hyperechogenic bowel: etiologies, management, and outcome according to gestational age at diagnosis in 279 consecutive cases in a single center. She basically said that with the negative NIPT these soft markers findings dont change my chances. Group Black's collective includes Essence, The Shade Room and Naturally Curly. But Im the same way, I can fully relax once I get those results . Absent of hypoplastic nasal bone, defined by a nasal bone that is not visible in first trimester or with a length of less than 2.5 mm in the mid-sagittal section of the fetal profile in second trimester, however the nasal bone length appears to be shorter in Korean fetuses than Caucasian and Chinese fetuses and is necessary to refer to race standards [39], and is described as one of the many phenotypic features of Down syndrome [6]. Information from prenatal aneuploidy screening facilitates anticipatory planning and may affect the decision to continue an established pregnancy. The Society of Obstetricians and Gynaecologists of Canada notes that NIPT is less validated in twin pregnancies and should be used with caution, and ACOG recommends against it.1,7 However, a meta-analysis of NIPT in twin pregnancies reported a sensitivity of 99% for trisomy 21 and 85% for trisomy 18.38, As a stand-alone test, second-trimester ultrasonography has a reported sensitivity of 50% to 60% for trisomy 21.1 A series of soft markers for aneuploidy, none of which are considered congenital anomalies, may suggest a higher likelihood of trisomy 21 or 18 when seen on second-trimester ultrasonography.1,39 Many fetuses with aneuploidy will not have these soft markers on ultrasonography, and these soft markers are common in normal fetuses. Some recent data indicate a positive association between NF measurement and congenital heart defects, with reported adjusted odds ratio of 14.8 (95% confidence interval [CI], 5.440.1). Individual references were reviewed from the bibliographies of other specialty guidelines with relevant articles reviewed in full text. Second-trimester serum quadruple screening performed between 15 and 22 weeks' gestation detects 81% of trisomy 21 cases. PPs are correct that the soft markers are far more likely to give you a false positive than getting a false negative on NIPT. They usually say worst case scenario. The ultrasound soft markers are found in the 5 major chromosomal aneuploidies: trisomies 21, 18, and 13; Turner syndrome; and triploidy [5,6]. The continuing enigma of the fetal echogenic intracardiac focus in prenatal ultrasound. and serum screening strategies.

Soft markers are ultrasound findings that do not represent a structural anomaly, may be a normal variant, but have been associated with increased risk for fetal aneuploidy. Women with positive aneuploidy screening results should be offered referral to maternal fetal medicine and genetic counseling to discuss invasive diagnostic testing with chorionic villus sampling or amniocentesis.1,7 Chorionic villus sampling is performed between 10 and 13 weeks' gestation and tests placental tissue obtained transcervically or transabdominally.43 Amniocentesis tests fetal cells grown in a culture from an amniotic fluid sample obtained transabdominally. The following are Society for Maternal-Fetal Medicine recommendations: (1) in women who have already received a negative cell-free DNA screening result, ultrasound at 11-14 weeks of gestation solely for the purpose of nuchal translucency measurement (Current Procedural Terminology code 76813) is not recommended (GRADE 1B); (2) diagnostic testing Almost same situation, had a negative NIPT test at 10 weeks. Therefore, a targeted ultrasound with particular attention to the fetal heart is reasonable when a thickened NF is identified after normal fetal karyotyping [25]. Screening for congenital infection should be part of prenatal workup, especially if VM with increased periventricular echogenicity, calcification, periventricular pseudocysts and intraventricular synechia [37]. Any NIPT test may have a false-positive, false-negative, or no-call result. Ultrasonographic measurement of fetal nasal bone length in the second trimester in Korean population. Mild pyelectasis: evaluating the relationship between gestational age and renal pelvic anterior-posterior diameter. Thank you for responding.

Gross, MD, receives consulting fees from Cradle Genomics, and has financial interest in The ObG Project, Inc. Planners and Managers: The PIM planners and managers, Trace Hutchison, PharmD, Samantha Mattiucci, PharmD, CHCP, Judi Smelker-Mitchek, MBA, MSN, RN, and Jan Schultz, MSN, RN, CHCP have nothing to disclose. The prevalence of neurodevelopmental delay in bilateral mild and moderate VM varies between 8% and 12% [19]. Shortened humerus length (HL) and femur length (FL) was observed in 0.4 to 3.9% of normal fetus [26]. So its a low likelihood anything will come back wrong on the microarray. As soft markers were introduced as markers for aneuploidy in high risk population, there have been efforts for clarification of their significance after normal FTS or NIPT [1,4]. She said the same to me that it was really the DS they were really worried about. As prenatal genetic screening strategies have greatly evolved in the last 2 decades, the relative importance of soft markers has shifted. We spoke with a genetic counselor before my amnio. In this document, isolated is used to describe a soft marker Should Amniocentesis or Chorionic Villus Sampling Be Offered to All Pregnant Women? Short Femur on the Second Trimester Ultrasound Report: What to Include in the Management Plan? The planners of this activity do not recommend the use of any agent outside of the labeled indications. The waiting is awful. As prenatal genetic screening strategies Bar-Yosef, O, Barzilay, E, Dorembus, S, Achiron, R, and Katorza, E (2017). Follow-up of sonographically detected soft markers for fetal aneuploidy. There they told me he had a mild urinary tract dilation, which they said they werent worried about and it would likely resolve but booked me in for a follow up anyway. Get guideline notifications Anyone have a similar situation? Aviram, A, Bardin, R, Wiznitzer, A, Yogev, Y, and Hadar, E (2015). Im very upset that for some reason I was not told about this second marker, as I definitely would have requested an amnio but it wasnt offered to me nor did they make any mention of the abnormalities both being markers. postnatal evaluation (GRADE 1C); (10) for fetuses with isolated High rates of cerebral palsy, seizures and impaired motor capabilities were observed in severe VM [1618]. ISUOG consensus statement on the impact of non-invasive prenatal testing (NIPT) on prenatal ultrasound practice. This article proposed a simple clinical summary for management of specific soft markers. isolated shortened humerus, femur, or both, we recommend a Second-trimester ultrasonography has limited utility in aneuploidy screening in women who have already been screened with a first- or second-trimester serum test. Universal NIPT adoption is not yet cost-effective.31 The Society for Maternal-Fetal Medicine designates some high-risk women as ideal candidates for NIPT screening (risk factors include maternal age of 35 years or older at the time of delivery; ultrasound findings indicating higher risk of aneuploidy; a previous pregnancy affected by trisomy 13, 18, or 21; or positive results from first- or second-trimester serum screenings).32 Positive NIPT results should be confirmed with invasive diagnostic testing, particularly if pregnancy termination is being considered.
