Genetic markers to determine if the donor and host samples can be distinguished
To schedule this test, you must telephone 800-533-1037, HLA customer service.
3 - 7 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
For more information, please view the literature below.
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, yellow-top (ACD) 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.
Hemolysis; clotted specimen
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)
