NIPT test
The Non-Invasive Prenatal Testing (NIPT) test is a screening method used during pregnancy to assess the risk of certain chromosomal abnormalities in a developing baby. It analyzes small fragments of fetal DNA circulating in the mother's blood. Here are the key points:
Purpose: NIPT screens for conditions like Down syndrome (trisomy 21), Edwards syndrome (trisomy 18), Patau syndrome (trisomy 13), and, in some cases, sex chromosome abnormalities.
Procedure: A simple blood sample is taken from the mother, typically after 10 weeks of pregnancy. No invasive procedures are needed.
Accuracy: NIPT is highly accurate, with detection rates over 99% for conditions like Down syndrome. However, it is a screening test, not diagnostic.
Benefits: It is safe for both the mother and baby, poses no risk of miscarriage, and provides early information about the baby’s health.
Limitations: While highly effective, NIPT cannot detect all genetic conditions and may require confirmation with diagnostic tests like amniocentesis or chorionic villus sampling (CVS).
NIPT is often recommended for high-risk pregnancies but is increasingly available for all pregnant individuals
