Research & evidence
Well-established; prenatal exome maturingPrenatal
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.
