About this test

Cancer of the bladder results in approximately 5000 deaths per year in the UK. Risk rises steeply with age, with over half of all deaths occurring in patients aged 70 years or more. The incidence of bladder cancer is three to four times higher in men than women, and roughly twice as high in white men as black men. Cigarette smoking markedly increases the risk for bladder cancer - with nearly half of all new cases of bladder cancer occurring in current or former smokers. Occupational exposure to chemicals used in the dye, leather, tyre and rubber industries has also been associated with an increased risk of bladder cancer. Early detection and treatment may prevent progression to invasive disease or allow for more effective treatment of non-invasive tumours. Regular follow-up testing is required amongst patients treated for early stage bladder cancer because of the high risk of recurrent disease.

Limitations of traditional testing methods have lead researchers to investigate various markers in attempt to develop a simple, non-invasive, but precise, laboratory test.

NMP22 is a protein found in human epithelial cells. In the urine of healthy individuals, the protein is present in low levels (less 10 U/mL). Most patients with bladder cancer release large quantities of NMP22 into the urine. 

Like many tunour marker tests, this test is not infallibel. it is possible to have normal levels of NMP22 yet still have bladder cancer. It is also possible to have elevated levels for innocent reasons e.g. extreme exercise prior to the test or a recen cytoscopy. Its use as a screening test is therefore not established and it is more commonly used in the diagnosis of people who have symptoms, or to test for the recurrence of bladder cancer. 

Who is this test for?

This test is for individuals who have been treated for bladder cancer and wish to test for recurrence. It is also for people who are at increased risk due to a history of smoking or exposure to certain chemicals through their work.

Important Information

Please see your doctor if you are suffering any unusual symptoms which persist - do not use these tests to self-diagnose. Tumour markers are most useful when viewed in conjunction with a clinical examination. Results do not constitute a diagnosis of cancer and markers are often tested to monitor treatment when cancer has already been diagnosed, or to check that it has not returned. Cancer markers can be elevated in benign conditions and results often produce false positives. Sometimes tumour markers can be normal even though cancer is present. Please make sure that you think carefully about the risks and benefits before taking this test.

Our tests are not a substitute for seeing your doctor, especially if you are suffering symptoms. Our doctors will interpret your results based on the information you have provided, but will not diagnose, consult or provide any treatment. You will be advised to see your doctor for any necessary follow-up action.
