Test ID: SCTF    
Sex Chromosome Determination, FISH, Tissue

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

This test includes a charge for application of the first probe set (2 fluorescence in situ hybridization probes) and professional interpretation of results.

 

Additional charges will be incurred for all reflex probes performed. Analysis charges will be incurred based on the number of cells analyzed per probe set. If no cells are available for analysis, no analysis charges will be incurred.

Specimen Type Describes the specimen type validated for testing

Tissue

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.
