Fluorescent In Situ Hybridization – FISH Test

Detecting serious changes and mutations in a person’s basic genetic material – the chromosomes – is one of the techniques used to diagnose different types of cancer. The test to detect these cancer-related abnormalities is called ‘FISH’ – fluorescent in situ hybridization

As with urinary cytology, this test can be performed on a urine sample.  By using special colored dyes that attach to chromosomes, doctors can identify odd breaks and changes that not only assist with diagnosis, but which can also help provide a strong indication of a patient’s prognosis and likelihood to respond to a given treatment.
