CLSI MM07 Abstract

Clinical and Laboratory Standards Institute document MM07-A2—Fluorescence In Situ Hybridization Methods for Clinical Laboratories; Approved Guideline—Second Edition provides information to ensure appropriate and reliable use of the FISH technology. FISH may be used to detect cytogenetic aberrations that are not readily evident by standard cytogenetic banding analyses. FISH technology allows for rapid identification of deletions, duplications, amplifications, and structural abnormalities of specific genes, loci, or chromosomal DNA/RNA sequences. The regions assessed by FISH are typically larger than those studied with PCR, yet smaller than those visualized microscopically with standard cytogenetics. FISH studies have become routine in medical laboratories.
