UroVysion
UroVysion
UroVysion (pronounced: u-ro-vi-sion) is a diagnostic test used primarily in the field of urology to detect bladder cancer in urine samples. The test uses Fluorescence In Situ Hybridization (FISH) technology to identify chromosomal abnormalities associated with bladder cancer.
Etymology
The term "UroVysion" is a combination of "uro", derived from the Greek word "ouron" meaning urine, and "vision", referring to the visual examination of cells under a microscope. The name reflects the test's purpose of visually examining urine samples for signs of bladder cancer.
Procedure
The UroVysion test involves the collection of a urine sample, which is then examined using FISH technology. This technology uses fluorescent probes to bind to specific DNA sequences in the cells present in the urine sample. The probes are designed to bind to sequences found in chromosomes 3, 7, 9, and 17, which are commonly abnormal in bladder cancer cells. If these abnormalities are detected, it may indicate the presence of bladder cancer.
