Start with fit

Is this the right test for you?

The best test starts with a clear clinical question. These are common reasons a clinician or family may consider this test.

  • ✓Patients preparing for a bone marrow transplant.
  • ✓Assessment of donor cell chromosomal composition.
  • ✓Evaluation for potential chromosomal abnormalities before transplantation.
  • ✓Monitoring post-transplant engraftment (in specific contexts).

In plain language

What this test helps you understand

This test helps determine the chromosomal sex (XX or XY) of donor cells and identify potential chromosomal abnormalities relevant to bone marrow transplantation, aiding in donor-recipient matching and predicting transplant success.
The FISH Opposite Sex BMT XX XY Test is a specialized diagnostic tool used in cytogenetics, particularly important for patients undergoing bone marrow transplantation (BMT). This test utilizes Fluorescence In Situ Hybridization (FISH) technology to examine chromosomes within cells. It specifically looks for the presence of XX (female) or XY (male) chromosomes in the donor cells. Understanding the chromosomal makeup of the donor cells is essential for ensuring compatibility and improving the success of the transplant procedure. This test helps identify potential chromosomal abnormalities that could affect the transplant outcome.
