Pretest counseling should include a discussion of baseline age-dependent risk, the potential for false-negative and false-positive results, the difference between screening and diagnostic tests, and what types of follow-up testing to expect.9 The use of decision aids (examples are available at https://www.psychosocialresearchgroupunsw.org/decision-aids.html) may improve a woman's ability to make an informed choice.10 All prenatal aneuploidy screening tests optimize detection rates (high sensitivity) and test for relatively uncommon conditions, resulting in high negative predictive values but low positive predictive values. Low risk NIPT but soft marker in ultrasound - January 2021 Birth Club I know the amnio is scary, but these days it's very safe. Multiple fetal intracardiac echogenic foci: not always a benign sonographic finding. Routine karyotyping of all pregnancies with these markers would have major implications, both in terms of miscarriage and in economic costs.

Isolated SUA was associated with a higher rate of cesarean section due to non-reassuring fetal heart rate, SGA, and a higher rate of placenta or umbilical cord abnormalities [35,36]. There is an association between CPCs and chromosomal defects, particularly trisomy 18. Goetzinger, KR, Cahill, AG, Macones, GA, and Odibo, AO (2011). I was definitely not told this when I was there several weeks ago. The genetic counselor said she was most concerned about Down syndrome, so thats definitely encouraging now that that is ruled out. As with first-trimester combined screening, laboratories report 5% of all second-trimester quad screening tests as positive, most of which will be false positives.

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]. 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. Fetal cell-free DNA testing has similar detection rates in high- and low-risk populations but has lower positive predictive values in younger women. She basically said that with the negative NIPT these soft markers findings don't change my chances. Controversially, the meta-analysis of Voskamp et al. The TRIP database was queried with similar terms. It seems to me every option is a good option in this case. A2-3, we recommend an individualized follow-up ultrasound assessment Discordant results, particularly when more than one aneuploidy is seen on NIPT and not confirmed by invasive diagnostic testing, may require a discussion with the patient regarding the risks and benefits of an occult malignancy workup.36,37, 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.1 In higher order pregnancies (triplets or more), serum screening is unvalidated, and only nuchal translucency alone can differentiate which fetus is potentially affected. Some sonographic findings are structural signs with little or no pathological significance, commonly known as soft markers [13]. Thank you for responding. If youve had it done how did it go? 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. Pagani, G, Thilaganathan, B, and Prefumo, F (2014). The waiting is awful. The overall prognosis of VM strongly depends on both the extent of enlargement and/or the presence of other abnormal findings or structural malformations. First- or second-trimester screening should not be performed after NIPT.1 Using NIPT only as a contingent follow-up test avoids invasive testing and its associated risks in most women,29 although some models suggest that as many as one in 50 pregnancies with positive first- or second-trimester screening and normal NIPT results may have an undetected chromosomal abnormality.30 The contingent approach is supported by the Society of Obstetricians and Gynaecologists of Canada.7 ACOG and the Society for Maternal-Fetal Medicine note that NIPT can be used in low-risk populations,1 although positive predictive values are lower. Gupta, G, Aggarwal, S, and Phadke, SR (2010).

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]. SMFM has addressed the topic, with a focus on how to integrate these findings within current screening programs (NIPS and serum marker screening), Society for Maternal-Fetal Medicine Consult Series #57: Evaluation and management of isolated soft ultrasound markers for aneuploidy in the second trimester, Get specially curated clinical summaries delivered to your inbox every week for free, Already an ObGFirst Member? NIPT and invasive prenatal testing are acceptably offered in high risk population (advanced maternal age, abnormal FTS results, history of fetal aneuploidy, known balanced translocation, or other chromosomal rearrangements in one of the parents) with soft marker and those with any combination of two soft markers [4,6]. As prenatal genetic screening strategies ! What are the Implications of a Short Fetal Humerus? Second-trimester quadruple (quad) screening includes alpha fetoprotein, unconjugated estriol, hCG, and inhibin A levels from maternal serum. All pregnant women should be counseled and offered aneuploidy screening regardless of maternal age. Battarbee, AN, Palatnik, A, Ernst, LM, and Grobman, WA (2015).

Therefore, a follow-up ultrasound at 32 weeks of gestation to rule out persistent pyelectasis should be performed. When results are negative, quad screening is added in the second trimester to refine risk, resulting in an overall trisomy 21 detection rate of 95%.15, In the contingent sequential screening approach, the results of first-trimester combined screening are classified into three risk categories: high (1% of results), intermediate (18% of results), or low (81% of results).18 Patients at high risk are offered invasive diagnostic testing, and patients at low risk receive no further testing.
