FISH FOR CLL 1 SET (CHR. 12 AND DEL 13Q OR DEL P53 AND DEL ATM)

Description

The FISH (Fluorescence In Situ Hybridization) test for Chronic Lymphocytic Leukemia (CLL) is designed to identify specific chromosomal abnormalities that have prognostic significance. The “1 set” likely refers to a panel of probes targeting specific chromosomal regions: deletion of 13q (13q14), trisomy 12, and deletions of TP53 (17p13) and ATM (11q22-23). These abnormalities are frequently found in CLL and are associated with different prognoses.
