In case of a positive result for toxoplasma infection in maternal serum, amniocentesis is performed to determine the presence of the pathogen in the amniotic fluid by amplification of DNA, using polymerase chain reaction [38]. In a 2015 randomized controlled trial comparing NIPT with first-trimester combined screening, NIPT detected 100% of trisomy 21 cases (false-positive rate of 0.06%) and 78.9% of trisomy 18 cases (false-positive rate of 0.01%).24 A 2017 meta-analysis reported that NIPT had a detection rate of 99.7% for trisomy 21 and 97.9% for trisomy 18, with a false-positive rate of 0.04% for both17 (Table 417,21). When I was 21 weeks, I had an anatomy scan that was normal and no markers were brought up to me-I just needed to be rechecked as they werent able to see about half the the heart due to his position so I returned at 24 weeks.

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. 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]. Catania, VD, Taddei, A, Pellegrino, M, De Marco, EA, Merli, L, and Manzoni, C (2017).

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. In low risk populations for aneuploidy, the presence of an IEF is not an indication for invasive procedures and with negative FTS or NIPT it may be described as not clinically significant or as a normal variant. Soft Markers Identied on Detailed Ultrasound Several markers identi!ed on second-trimester ultrasound examination are associated with increased .
