Array Comparative Genomic Hybridization (aCGH)
Array Comparative Genomic Hybridization (aCGH) is a technology that allows for the screening of all 46 chromosomes for unbalanced abnormalities, such as Down syndrome. This test helps ensure that only embryos deemed to be normal are transferred back into the uterus. The biopsy procedure involves taking a small sample of cells (3-7) from a blastocyst embryo, usually on day 5. We have the ability to bank the biopsy samples and freeze the embryo afterwards for transfer in the future. Typically, our patients prefer to bank at least 8 biopsy samples before sending them out for testing to make the process more cost-effective. Once the samples are sent out to ZytoGen for testing, results are typically available within 1-2 days.
