FISH - Fluorescent in Situ Hybridization

Fluorescent in Situ Hybridization (FISH) is a test that maps the genetic material in human cells, including specific genes or portions of genes. A FISH test is useful for diagnosing some types of cancer because of its ability to detect genetic abnormalities associated with the disease.

FISH has a much faster turnaround time than conventional chromosome analyses, which gives critical information to physicians to administer the drug All-Trans-Reinoic-Acid (ATRA) in time to patients with Acute Promyelocytic Myeloid Leukemia.
