Hematologic Specified FISH, Varies
Use
This test is useful for the detection of specific chromosomal abnormalities in hematologic malignancies. By using gene-specific probes and various FISH probe strategies, it helps characterize chromosome abnormalities for diagnostic, prognostic, and therapeutic purposes. FISH offers a reliable method of identifying genetic alterations that can inform treatment decisions and patient management in hematologic disorders.
Special Instructions
It is important to consult with the laboratory before ordering this test. Ensure that the specific FISH probes to be analyzed are specified on the order to avoid delays. The first aspirate from bone marrow collection is preferable, and only send specimens in the original tube without aliquoting.
Limitations
This test is not approved by the US Food and Drug Administration and is intended for use as an adjunct to existing clinical and pathologic information. While bone marrow is the preferred specimen type, a blood specimen may be used if malignant cells are present in the blood. The absence of an abnormal clone does not rule out the presence of a neoplastic disorder.
