Additional Interpretation: Chimerism following bone marrow engraftment is a leading cause of morbidity and mortality in the bone marrow transplant population. Peripheral blood cells arising from the recipient as well as the donor appear in the peripheral circulation. Early monitoring of this state is necessary to allow early intervention.

Methodology: Peripheral blood or bone marrow DNA from the recipient in a marrow transplant are amplified with the 16-locus Human STR panel (Promega PowerPlex 16 HS) and the PCR products are characterized by capillary electrophoresis. The allele profile is then compared to the original profile from donor and recipient for informative alleles. Results for engraftment monitoring of single donor transplant are reported as percentage of donor cells in the post-transplant sample and calculated from the peak area for each marker in the sample. For a double donor transplant, the identity and the percentage of each donor cells are reported as well as the total percentage of donor cells.
