Test Details
Methodology
Antibody-mediated positive selection of CD33/CD66 cells and separation with magnetic nanoparticles. DNA analysis by polymerase chain reaction (PCR) of short tandem repeats (STR)
Result Turnaround Time
3 - 7 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Use
Monitor the level of donor CD33/CD66b cells in the recipient (patient-host) of a hematopoietic stem cell transplant. Polymorphic loci determined in the preëngraftment testing are used as a reference for the evaluation.
