Does the DNA sample need to be collected from a cheek swab?

No, but the cheek swab yields high amounts of DNA. CG Labs can also extract the DNA from hair or skin samples. With hair, ensure that several body hairs are collected and that these hairs still have the root attached. Alternatively, a light scraping of the skin will result in a sufficient amount of skin cells to extract the DNA. Detailed instructions for all of CG Labs' collection methods are provided.
