Assess recipient genotype.
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 3 mL whole blood (Min: 1 mL) OR 1 mL bone marrow OR 2 buccal brushes in a sterile, dry tube.
Post-transplantation results will be compared to pre-transplant recipient and donor genotypes, therefore, donor and recipient specimens must be obtained and genotyped before the transplant event occurs.
Ambient: 1 week; Refrigerated: 1 month; Frozen: 6 months
Background Information for Chimerism, Recipient Pre-Transplant:
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).
Kit Used: AmpFLSTR Identifiler® PCR Amplification Kit, Applied Biosystems.
Limit of Detection: 2 percent of minor cell population.
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.
