Genetic markers to determine if the donor and host samples can be distinguished
Determine if the potential donor and host have genetic differences that can be used to monitor the acceptance of a stem cell transplant
Identical (monozygotic) twins will have identical alleles and, therefore, host and donor will not be distinguishable. Note: If determination of twin zygosity (monozygotic versus dizygotic) is needed, telephone 800-533-1037, HLA customer service.
DNA analysis by polymerase chain reaction (PCR) of short tandem repeats (STR)
Whole blood or LabCorp buccal swab kit (buccal swab collection kit contains instructions for use of a buccal swab)
Adult tube or LabCorp buccal swab kit
3 mL or four buccal swabs
Lavender-top (EDTA) tube or LabCorp buccal swab kit. When submitting buccal swabs, please telephone 800-533-1037.
Maintain whole blood at room temperature. Keep buccal swabs dry and at room temperature.
Causes for Rejection
Hemolysis; clotted specimen
To schedule this test, you must telephone 800-533-1037, HLA customer service.
