Fluorescence in situ hybridization (FISH) is a test that “maps” the genetic material in a person's cells. This test can be used to visualize specific genes or portions of genes. It uses fluorescent probes that bind to only those parts of the chromosome with a high degree of sequence complementarily to detect and localize the presence or absence of specific DNA sequences on chromosomes. Fluorescence microscopy can be used to find out where the fluorescent probe is bound to the chromosomes. FISH test can detect genetic abnormalities associated with cancer. It is done on breast cancer tissue removed during biopsy to see if the cells have extra copies of the HER2 gene.
