Ordering Guidance

This test does not include a pathology consultation. If a pathology consultation is required, order PATHC / Pathology Consultation and the appropriate fluorescence in situ hybridization (FISH) test will be ordered and performed at an additional charge.

This testing is not appropriate for distinguishing tissue from the same gender, as in a same-sex transplant or potential tissue mix-up between 2 male patients or 2 female patients.

This evaluation can be more complicated in a post-transplant neoplastic evaluation and may not produce a confirmatory result.
