Note: This test was previously called CLL FISH Panel (non-New York). It is now New York state-approved and available to all clients.
Clinical Significance
The CLL FISH panel is used for the detection of chromosome aberrations observed in chronic lymphocytic leukemia/small lymphocytic lymphoma, which are useful in prognosis and prediction of time to treatment in CLL patients when used in combination with other clinical and diagnostic findings. CCND1/IgH is used to rule out mantle cell leukemia/lymphoma.
