About this test
Rapid detection of the common aneuploidies.
What the report contains
Rapid result for trisomy 21/18/13 (± X, Y).
Evidence and limitations
cfDNA/NIPT is a highly accurate screening test for the common trisomies. Microarray and QF-PCR are first-line diagnostics on invasive samples, with prenatal exome adding yield in selected cases.
Limitations
cfDNA/NIPT is a screening test, not a diagnosis: a high-risk result requires confirmatory invasive testing, and performance for microdeletions is more limited than for the common trisomies.
Ordering and consent
This test needs genetic counselling and written consent; your clinic confirms both at ordering.
