Remarks
Patient History and Informed Consent for Non-Invasive Prenatal Testing (NIPT) form required. 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.
