What is a Urovysion fish test?
Urovysion™ fluorescence in situ hybridization (FISH) is a sensitive and specific test used to diagnose urothelial carcinoma in urine. It detects aneuploidy of chromosomes 3, 7 and 17, and loss of both 9p21 loci in malignant urothelial cells.
Does abnormal urine FISH test always indicate bladder cancer?
FISH detected 95% of cases with high-grade carcinoma, while cytology detected 41% of such cases. FISH yielded an overall specificity of 65%, compared to 93% with cytology. These researchers recommended FISH as a useful initial diagnostic tool in patients suspected of both new and recurrent bladder cancer.
What is a cxbladder test?
Cxbladder tests measure the gene expression levels of five biomarkers in urine that effectively rule out or detect the presence of bladder cancer. With a single urine sample, Cxbladder can provide peace of mind and positive treatment direction for patients, caregivers and doctors.
What is cytology and FISH?
Abstract. Fluorescence in situ hybridization (FISH) is a technique that uses fluorescently labeled DNA probes to detect chromosomal alterations in cells.
Does a positive FISH test mean cancer?
What the Results Mean. FISH testing usually returns one of two results: positive or negative. Positive means your breast cancer cells make too much HER2 and your doctor should treat you with drugs that target that protein. Negative means the protein isn’t involved in the growth of your tumor.
Is cxbladder FDA approved?
These included the six FDA-approved tests (quantitative and qualitive NMP22, quantitative and qualitative BTA, FISH, and uCyt+) as well as a laboratory developed test that does not require FDA approval termed CxBladder.
How much does cxbladder cost?
Additionally, at a cost of around $300 per test, the cost-effectiveness of Cxbladder compared with the currently recommended strategy has yet to be elucidated.
How does FISH analysis work?
During a FISH test using a sample of the patient’s tissue, special colored dyes are attached to specific parts of certain chromosomes in order to visualize and count them under a fluorescent microscope and to detect cancer-promoting abnormalities. Abnormalities found in cancer cells include: Translocation.
What is the UroVysion assay?
Bladder cancer detection using FISH (UroVysion assay) UroVysion is a fluorescence in situ hybridization assay that was developed for the detection of bladder cancer in urine specimens.
What is the UroVysion FISH test for urothelial cancer?

What are the indications and limitations of the UroVysion kit?
Indications and Limitations Of Use. Intended Use. The UroVysion Bladder Cancer Kit (UroVysion Kit) is designed to detect aneuploidy for chromosomes 3, 7, 17, and loss of the 9p21 locus via fluorescence in situ hybridization (FISH) in urine specimens from persons with hematuria suspected of having bladder cancer.
What fluorophores are in the UroVysion bladder cancer kit probes?
The UroVysion Bladder Cancer Kit probes are directly labeled with one of the Vysis fluorophores; SpectrumRed, SpectrumGreen, SpectrumAqua or SpectrumGold. The UroVysion Bladder Cancer Kit consists of:
