Additional Technical Information
Ordering Recommendation

First- or second-tier screening test for the common fetal aneuploidy disorders: trisomy 13, trisomy 18, trisomy 21 (Down syndrome), Turner syndrome, sex chromosome aneuploidies (XXX, XXY, XYY), and triploidy; as well as microdeletions causing 22q11.2 deletion (DiGeorge or velocardiofacial [VCFS] syndrome), 1p36 deletion, Angelman, Prader-Willi, and cri-du-chat (5p-) syndromes. Testing may be offered to pregnant women from 9 weeks 0 days gestation to term. Test is not recommended for women who are carrying more than one fetus or have a known twin demise, patients who have used an egg donor, surrogates who have not used their own egg, or women who have had an allogenic bone marrow transplant.

Note

Testing utilizes a single-nucleotide polymorphism (SNP)/informatics-based approach to detect fetal copy number for the five chromosomes responsible for the majority of live-birth aneuploidies (chromosomes 13, 18, 21, X, Y, and triploidy) and certain specific microdeletion syndromes (see current list of microdeletion syndromes listed under "Ordering Recommendations"). This is a screening test to help identify fetuses at risk for Down syndrome, trisomy 18, trisomy 13 and Turner syndrome, as well as fetuses affected with the specified microdeletion syndromes listed. This test should not be considered diagnostic. All positive results should be confirmed by amniocentesis or CVS.
