Plasma Cell Proliferative Disorder, High Risk with Reflex Probes, Diagnostic FISH Evaluation, Bone Marrow
Use
This test is useful for detecting recurrent high-risk chromosome abnormalities associated with multiple myeloma or other plasma cell proliferative disorders at diagnosis, using a laboratory-designated probe set algorithm. It helps in identifying high-risk prognostic markers associated with multiple myeloma or other plasma cell proliferative disorders. However, this test should not be used to track the progression of the disease.
Special Instructions
Fresh bone marrow within 96 hours post-collection is required. If the specimen is received as a fixed cell pellet or more than 96 hours after collection, the test automatically reorders as MFCDF. If the specimen is paraffin-embedded, it reorders as PLASF.
Limitations
The test is not FDA approved and serves as an adjunct to existing clinical and pathologic information. It may be canceled if insufficient plasma cells are identified or if there are no FISH signals post-hybridization. It is limited to the detection of specified chromosomal abnormalities related to plasma cell disorders.
