We’ll test them for any diseases or infections, so we can make sure your cord blood is safe to use for a transplant. This includes tests for HIV, hepatitis B and C, syphilis and HTLV. Some of these tests are not undertaken as part of usual maternity care. Other tests such as for malaria may be done depending on your travel history. Also, we do DNA analysis to obtain your tissue type (HLA) to help find a better match. If you test positive for anything, we’ll pass the information to your doctor who will advise you on any treatment.
