Methodology

DNA Extraction

Additional Information

All extracted DNA samples will be held for 90 days. Extracted DNA samples of fetal origin (e.g. Chorionic villi, cultured amniocytes, etc.) and their corresponding maternal DNA samples, will be held for 1 year. If no testing is ordered within this time frame, the sample will be discarded.
