Abstract
Objective
To assess the positive predictive value of noninvasive prenatal testing as a screening test for sex chromosome aneuploidy with different maternal characteristics and prenatal decisions in positive cases.
Materials and methods
We retrospectively analysed 45,773 singleton pregnancies with different characteristics that were subjected to NIPT in the Maternity and Child Health Hospital of Anhui Province. The results were validated by karyotyping. Clinical data, diagnostic results, and data on pregnancy outcomes were collected.
Results
In total, 314 cases were SCA positive by...
