FISH

Term from Diagnostics industry explained for recruiters

FISH (Fluorescence In Situ Hybridization) is an important testing method used in medical laboratories to detect genetic changes in cells. Think of it as a special microscope technique that uses fluorescent markers to light up specific parts of genes or chromosomes, making them visible and countable. This helps doctors diagnose diseases, especially cancer, and choose the right treatments. It's like having a highlighter that marks specific words in a book, but in this case, it marks specific genetic information in cells.
