Also written as: NIFTY — Non-invasive Fetal Trisomy test
Non-invasive fetal trisomy test using cell-free DNA analysis from maternal blood.
Full Definition
NIFTY (Non-invasive Fetal Trisomy test) is a prenatal screening method that analyzes cell-free fetal DNA circulating in maternal blood to detect chromosomal abnormalities, particularly trisomies 21, 18, and 13. This test has largely replaced older serum screening methods due to its higher accuracy and lower false-positive rate. Results are typically available after 10 weeks of gestation, making it an important tool in early prenatal diagnosis.
Usage
Usage note: Always capitalize as acronym; distinguish from invasive diagnostic procedures in patient communications.
