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.
