Use to assess recipient genotype and compare to donor genotype prior to allogeneic hematopoietic stem cell transplant. Pretransplant genotyping is required to enable posttransplant chimerism and engraftment monitoring. For posttransplant monitoring, refer to Chimerism, Posttransplant (3005454).
Polymerase Chain Reaction/Fragment Analysis
New York DOH Approval Status
Lavender (EDTA), pink (K2EDTA), or yellow (ACD solution A or B). OR bone marrow in lavender (EDTA). OR buccal brushes from recipient.
Transport 2 mL whole blood (Min: 1 mL) OR 1 mL bone marrow (Min: 1 mL) OR 2 buccal brushes in a sterile, dry tube. (Min: 2 brushes)
Refrigerated. Also acceptable: Ambient.
Posttransplant results will be compared to pretransplant recipient and donor genotypes, therefore, donor and recipient specimens must be obtained and genotyped before the transplant event occurs. If transplant event occurred prior to specimen collection, dry buccal brushes (not bloody) are acceptable.
Room temperature: 1 week; Refrigerated: 1 month; Frozen: Unacceptable
Background Information: Chimerism, Recipient Pretransplant
Indication: Monitoring for bone marrow transplant patients; correlation with clinical status and consideration of the interval between bone marrow transplantation and testing is necessary for proper interpretation of results.
Methodology: PCR followed by capillary electrophoresis. Specimens are analyzed using 15 autosomal markers (D8S1179, D21S11, D7S820, CSF1PO, D3S1358, THO1, D13S317, D16S539, D2S1338, D19S433, vWa, TPOX, D18S51, D5S818 and FGA) and one gender marker (amelogenin).
Limitations: Diagnostic errors can occur due to rare sequence variations.
This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.
