Why This Test Is Done

Your doctor may order this test if you have symptoms like frequent urination, pain during urination, blood in urine, or unexplained weight loss. It’s also used to monitor conditions like interstitial cystitis or bladder cancer.

What to Expect Before the Test

No special preparation is needed. You’ll likely provide a midstream urine sample in a clean container. Avoid using urinary tract medications or douches 24 hours before testing if possible.

What Happens During the Test

The lab technician will examine your urine under a microscope to look for cells, bacteria, crystals, or other abnormalities. Results may show signs of infection, inflammation, or other urinary issues.

What the Results Mean

Abnormal findings, such as abnormal cells, white blood cells, or bacteria, may suggest urinary tract infections, bladder stones, or other conditions. Your doctor will interpret results in the context of your symptoms and medical history.

Reference range

Not typically detected in normal urine sediment; occasional urothelial (bladder) cells may be seen in normal individuals, particularly in females. Report as Present, Few, Moderate, or Many.N/A

Specimen: urine

No special preparation required. Patient should follow standard mid-stream clean-catch urine collection technique. Avoid contamination with vaginal or external genital secretions.

Frequently asked questions

What causes abnormal cells in urine microscopy?
Abnormal cells in urine can result from urinary tract infections, bladder irritation, inflammation, or sometimes from conditions like interstitial cystitis or bladder cancer. Symptoms like pain, frequent urination, or blood in urine often prompt this test.
How long does it take to get results?
Results are typically available within 24 to 48 hours, depending on lab processing times. Your doctor will contact you once they have the findings.
Can I drink alcohol before this test?
Alcohol itself won’t affect the test results, but it may increase the risk of urinary tract irritation or infection. Avoid excessive alcohol use before testing if you have symptoms like pain or frequent urination.
