Why Is This Test Done?

Your healthcare provider may order this test if you have symptoms like blood in your urine, frequent urination, pain during urination, or if you have a history of urinary tract or bladder cancer. It can also be part of routine screening for certain high-risk groups.

What Happens During the Test?

You’ll urinate into a clean container provided by your healthcare team. The sample is then sent to a lab where trained professionals examine the cells under a microscope for abnormalities.

Sample Preparation and Testing Process

The urine sample is processed to concentrate cells, which are then spread onto slides. These slides are stained and examined by a pathologist or cytotechnologist to identify any abnormal cells.

What Are the Possible Results?

Results can range from normal (no abnormal cells found) to positive for abnormal cells, which may suggest conditions like bladder cancer, inflammation, or infection. Follow-up tests or further evaluation may be needed based on the results.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What does a positive urine cytology test mean?
A positive result means your healthcare provider may find abnormal cells in your urine. This could signal a condition like bladder cancer, but it may also be due to other factors like infection or inflammation. Further testing, such as a cystoscopy or biopsy, will be needed to determine the cause.
The frequency depends on your medical history, symptoms, and risk factors. Your healthcare provider will determine if this test is part of your regular check-up or if it’s needed due to specific concerns, such as a history of cancer or recurring urinary issues.
No special preparation is needed. You may be advised to avoid certain medications or foods if you have specific instructions from your healthcare provider, but generally, you can proceed as usual. Drink plenty of water to help flush your urinary system.
Is there any risk or discomfort associated with this test?
There is no discomfort involved. The process is quick and painless. The only minor consideration is ensuring you provide a fresh urine sample for accurate results.
