However, we could not identify this false negative NIPT case due to potential mosaicism, as we did not collect tissue samples from the umbilical cord and placenta for further examination after delivery. Numerous studies have shown sensitivity rates for NIPT was approximately 99% with false positive rates below 1% and the positive predictive value is limited to 40% to 90%.

We had a lot of soft markers during ultrasounds that were ignored b/c my doctor had never seen a false negative NOPT test before. Genetic specialists and obstetricians told Fox that noninvasive prenatal testing works well for screening the fetus risks for common chromosomal disorders like Down syndrome but said the tests are not as accurate for relatively rare conditions associated with chromosomal microdeletions such as Wolf-Hirschhorn syndrome. We present the importance of proper pretest and posttest genetic counseling to ensure prenatal patients are able to make informed decisions and are educated appropriately about the benefits and limitations of NIPT.

The couple decided that they wanted to know if there was a chance that the baby had Down's Syndrome and privately paid for a blood test known as NIPT - a non-invasive prenatal test - which examines the DNA of tiny particles of the placenta circulating in the mother's blood. However, postnatally, the newborn was diagnosed with Down syndrome with the 46,XY,der(21;21)(q10;q10),+21 karyotype.

Pregnancy outcome following prenatal diagnosis of chromosomal anomaly: a record linkage study of 26,261 pregnancies. A meta-analysis of 117 cohort studies based on NIPT in singleton pregnancies demonstrated sensitivity and specificity for trisomy 21 (T21, Down syndrome) of 99.4 and 99.9%, for trisomy 18 (T18, Edwards syndrome) of 97.7 and 99.9%, and for trisomy 13 (T13, Patau syndrome) of 90.6 and 100%, respectively [5]. It is more common with other chromosomes eg 13, 18, but far less common with T21 to not have foetal involvement. This is where we found out it was a mosaic diagnosis for T21. Genet Med.

To explore the possible causes of our false negative case using NIPT, we first analysed the known factors that cause a low foetal fraction of cfDNA. The patients mother reported that the prenatal history for this pregnancy was relatively uncomplicated, with normal ultrasound finding throughout the pregnancy until 20-week gestation, when a CAVCD was detected.
