Why This Test Is Done

Your doctor may order this test if they suspect conditions like infections (e.g., urinary tract infections), inflammatory diseases, or conditions affecting blood or immune cells. For example, unusual cells in urine might suggest kidney disease or bladder cancer, while abnormal cells in cerebrospinal fluid could indicate neurological issues like meningitis or multiple sclerosis.

What to Expect Before the Test

No special preparation is typically needed unless your doctor specifies. For urine tests, you may be asked to collect a midstream clean-catch sample. For other fluids (e.g., cerebrospinal fluid), you may need to undergo a procedure like a lumbar puncture. Always follow your doctor’s instructions carefully.

During the Test Process

A healthcare professional will collect the fluid sample (e.g., urine, spinal fluid, or other bodily fluids) and send it to a lab. A trained technician will then examine the sample under a microscope to identify and count any abnormal cells. This process usually takes a few hours.

Possible Results and Next Steps

If abnormal cells are found, your doctor will review the results with you and may recommend additional tests or treatments, such as further imaging, biopsies, or specialized medical consultations. Normal results mean no obvious abnormalities were detected in the fluid sample.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What does it mean if abnormal cells are found in my urine?
Abnormal cells in urine could indicate conditions such as urinary tract infections, bladder cancer, kidney disease, or other inflammatory processes. Your doctor will discuss the findings with you and may recommend further testing to determine the exact cause.
Can this test be done at home?
No, this test requires a lab setting. Urine tests may be done at home using a kit, but the microscopic examination and interpretation are performed in a clinical or laboratory environment.
How long will it take to get my results?
Results are typically available within a few days to a week, depending on lab processing times. Your doctor will contact you once the results are ready for discussion.
