Non-Invasive Prenatal Testing for Fetal Aneuploidy
2007537
Ordering Recommendation

First- or second-tier screening test for the most common fetal aneuploidy disorders (trisomy 13, trisomy 18, trisomy 21 [Down syndrome], Turner syndrome, sex chromosome aneuploidies [XXX, XXY, XYY], triploidy). Testing may be offered to pregnant women with singleton or twin pregnancies from 9 weeks 0 days gestation to term. Test may also be ordered for women who have used an egg donor or for surrogate pregnancies. Test is not recommended for women carrying triplets or higher-order multiples, who have a known twin demise, who are carrying twins and used an egg donor/surrogate, or who have had an allogenic bone marrow transplant. IMPORTANT: Twin, egg donor/surrogate specimens will be run at Natera and reported through ARUP.

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). This is a screening test to help identify fetuses at risk for Down Syndrome, trisomy 18, trisomy 13 and Turner Syndrome. This test should not be considered diagnostic.  It is recommended that any positive result should be confirmed by amniocentesis or CVS.
