Different genotype of the fetus and the placental trophoblast, either confined placental mosaicism or true-fetal mosaicism with feto-placental discordance, can lead to a false positive or false negative result respectively. An individual with Down syndrome has three copies of chromosome 21 rather than two; for that reason, the condition is also known as Trisomy 21. In a woman who is pregnant, most of the cfDNA is derived from turnover of maternal cells. according to LabCorp it says Chromosome 21 - Negative, Chromosome 18 - Negative, and Chromosome 13 - Negative. 2005-2023Everyday Health, Inc., a Ziff Davis company.

The major clinical benefit of NIPT is to increase the detection rate for the targeted abnormalities, while simultaneously reducing the number of false positive results and invasive tests. What most worries genetic counselors and ethicists though are false positives that could result in unnecessary abortions of healthy fetuses. Associated medical issues presenting after newborn period include. Table 1 shows the PPV of a high-risk screening result and NPV of a low-risk screening result for three groups with different prior risk levels. Kinnings SL, Geis JA, Almasri E, et al.
