Non-invasive Prenatal Testing (NIPT)

SA Pathology is now providing blood collection services for non-invasive prenatal testing (NIPT) for pregnant women across South Australia.

NIPT, or nest screening, is performed using whole genome sequencing of cfDNA to determine the chance of a chromosome condition in the pregnancy. It is performed any time after 10 weeks gestation using a blood sample taken from the pregnant woman and does not pose any risk to the fetus. Nest has a high sensitivity and specificity for common chromosome conditions such as Trisomy 21, 13 and 18, and has the potential to detect chromosome changes down to 7Mb in size.

Women seeking this testing can attend any of SA Pathology’s collection centres located across metropolitan and regional South Australia.

Request forms are available for download from the SA Pathology Test Catalogue or Clinicians are requested to write NEST on the request form. An NIPT – Agreement to Pay form must also accompany the sample.
