DefinitionBy Mayo Clinic staff
Noninvasive prenatal testing (NIPT), also known as noninvasive prenatal diagnosis (NIPD), is a screening method for detecting certain specific chromosomal abnormalities in a developing baby.
Noninvasive prenatal testing is a sophisticated blood test that examines fetal DNA in the maternal bloodstream to determine whether your baby is at risk of Down syndrome, extra sequences of chromosome 13 (trisomy 13), extra sequences of chromosome 18 (trisomy 18) or a sex chromosome abnormality, such as Turner syndrome. The testing can also be used to determine a baby's sex and rhesus (Rh) blood type.
Currently, noninvasive prenatal testing is only available for women who have certain risk factors.
Noninvasive prenatal testing might help you avoid other tests that might put your pregnancy at risk. Your health care provider or a genetic counselor will discuss whether noninvasive prenatal testing might benefit you and how to interpret the results.
