Array Comparative Genomic Hybridization Prenatal

Test Description:
Whole genome oligonucleotide aCGH is offered for prenatal diagnostic evaluation via direct or cultured amniocytes or chorionic villi for ultrasound abnormalities, abnormal screening results, previous pregnancies with chromosome abnormalities or for parental concern. aCGH can also be used to accurately size a chromosomal aberration detected by chromosome analysis or to further evaluate chromosome results that indicate an apparently balanced rearrangement. Benign copy number variants will not be reported and parental samples may be requested for follow-up. Maternal cell contamination studies are performed in conjunction with prenatal aCGH.
