Chimerism, Recipient, Pretransplant
Also known as: STR_PRE
Use
The test is used to assess the genotype of a recipient prior to allogeneic hematopoietic stem cell transplantation. This pretransplant genotyping is necessary to enable monitoring of chimerism and engraftment post transplantation. It is crucial for bone marrow transplant patients, as it helps in the correlation with clinical status and consideration of the interval between transplantation and testing for accurate interpretation of results.
Special Instructions
Not provided.
Limitations
Diagnostic errors can occur due to rare sequence variations. Results need to be correlated with clinical status and timing between transplantation and testing. The test has not been cleared or approved by the U.S. Food and Drug Administration, but it is performed in a CLIA-certified laboratory and intended for clinical purposes.
