Transplant Engraftment Monitoring (Chimerism Testing)


Specimen Requirements


Specimen

Whole blood or LabCorp buccal swab kit (buccal swab collection kit contains instructions for use of a buccal swab)


Volume

Adult tube or LabCorp buccal swab kit


Minimum Volume

3 mL or four buccal swabs


Container

Lavender-top (EDTA) tube, yellow-top (ACD) tube, or Labcorp buccal swab kit. When submitting buccal swabs, please telephone 800-533-1037.


Storage Instructions

Maintain whole blood at room temperature. Keep buccal swabs dry and at room temperature.


Causes for Rejection

Hemolysis; clotted specimen


Test Details


Use

Determine if the potential donor and host have genetic differences that can be used to monitor the acceptance of a stem cell transplant


Limitations

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.


Methodology

DNA analysis by polymerase chain reaction (PCR) of short tandem repeats (STR)
