Abstract
Objectives: Fluorescence in situ hybridization (FISH) is a reliable method to detect a deletion on chromosome 13q14. Currently, three commercial probes are available for FISH testing in clinical cytogenetics laboratories, RB1, D13S319, and D13S25, with the D13S319 probe most commonly used for 13q deletion. In this study, we compared FISH test results among these three probes in CLL cases with positive 13q deletion. We found that the D13S25 probe set has the highest detection rate of the percentage of the biallelic 13q deletion.
