Key points
- Ask about cost and coverage before the blood draw.
What NIPT can tell you
Noninvasive prenatal testing, or NIPT, is a blood test usually available from 10 weeks. It analyzes cell-free DNA, largely from the placenta, to estimate the chance of certain chromosome conditions, especially Down syndrome, trisomy 18, and trisomy 13. Screening and diagnostic options should be offered regardless of age. You may choose or decline testing. ACOG prenatal screening information
Benefits and limitations
NIPT is the most accurate screening approach for the common trisomies, but it does not diagnose them. The blood draw has minor risks such as bruising; it does not carry the procedure-related miscarriage risk of amniocentesis or CVS. False-positive and false-negative results can happen. How likely a positive result is to be correct depends on the condition and your circumstances.
Routine screening for rare microdeletions or broad chromosome changes is not recommended for everyone. Ask what the panel includes; more conditions on a panel do not always mean more useful answers. Twin pregnancies need specific counseling. SMFM updated guidance
What happens after a result
A high-risk result should lead to genetic counseling and an offer of diagnostic testing before making irreversible decisions. A “no result” or “low fetal fraction” result is not a normal result; it needs follow-up. Your clinician may discuss ultrasound, diagnostic testing, or a repeat blood draw based on the situation.
