It is also worth noting that paternity tests cannot be performed for marrow transplant recipients using blood samples, but rather must utilize cells from the mucous membrane in the oral cavity or from the hair. This is because the DNA present in the blood is from the donor.
值得注意的是，骨髓移植者如果要做親子鑑定，不能採血液做檢體，必須採口腔黏膜細胞或頭髮，因為血液中的 DNA 是捐髓者的。
