Chimerism Analysis With CD56 Cells (Transplant Monitoring)
Also known as: Cell Sorting CD56, Chimerism Analysis With Sorted NK Cells, Engraftment Monitoring Sorted NK Cells
Use
Monitor level of donor CD56 cells in the recipient (patient-host) of a stem cell transplant. Polymorphic loci determined in the preëngraftment testing are used as a reference for the evaluation.
