As well as the above tests we'll do virology and bacteriology tests, looking for any dangerous viruses or bacteria, to make sure it’s safe for a transplant. We also check for genetic conditions, duplicating the neonatal screening tests (eg haemoglobinopathies) We’ll also do haematology tests to see how many stem cells there are in your cord blood donation and to find out the tissue type. That way we can match your donation to someone in need of a lifesaving transplant.
