About test
What does FISH FOR POST BMT XX/XY CHIMERISM (SEX MISMATCHED BMT) - (Outlab) measure?
This test uses fluorescence in situ hybridization (FISH) to detect X and Y chromosome patterns after a sex-mismatched bone marrow transplant. It estimates the proportion of donor- and recipient-origin cells based on their sex chromosome signals. It may be used to monitor donor cell engraftment, assess changes in chimerism over time, or support evaluation of transplant follow-up findings.
