Why This Test Is Done

Your healthcare provider may order this test if you have symptoms like blood in urine, frequent urination, pain during urination, or if you’ve been diagnosed with bladder conditions. It’s also used to monitor treatment for bladder cancer or other urinary issues.

What to Expect During the Test

You’ll provide a urine sample, typically collected in a clean container. The sample is then sent to a lab for microscopic analysis. No special preparation is usually needed, but follow any instructions your provider gives you.

Possible Findings and Their Meanings

The test looks for different cell types, including white blood cells (indicating infection), red blood cells (possible bleeding), or abnormal cells (like those seen in cancer). Normal results mean no obvious abnormalities are found in the sample.

How the Results Are Interpreted

Results are reviewed by a trained lab professional or pathologist. They’ll compare the findings to your symptoms and medical history. Abnormal results may lead to further testing, like a biopsy or additional imaging.

Reference range

Few or rare bladder epithelial cells per HPF; occasional presence is generally considered within normal limits for healthy individualsN/A

Specimen: urine

No fasting required. Patients should follow standard midstream clean-catch urine collection technique. Avoid contamination with external genital secretions. Women should clean the periurethral area before collection.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What does this test measure?
This test measures the presence and type of cells in your urine, specifically focusing on cells collected from the bladder area. It helps identify issues like infections, inflammation, or cancerous cells.
What are the normal results?
Normal results typically show few or no abnormal cells, with a focus on healthy cells like epithelial cells from the bladder lining. However, normal ranges can vary based on individual health and clinical context.
How soon will I get my results?
Results are usually available within 1 to 3 business days, depending on lab processing times. Your healthcare provider will discuss the findings with you during a follow-up visit.
