Cytology exam of urine
Alternative namesUrine cytology
DefinitionA cytology exam of urine is used to detect cancer and inflammatory diseases of the urinary tract.
How the test is performed
Collect a urine specimen and send it to the laboratory.
Check your baby frequently and remove the bag after the infant has urinated into it. For active infants, this procedure may take a couple of attempts -- lively infants can displace the bag, causing an inability to obtain the specimen. The urine is drained into a container for transport back to the health care provider.
How to prepare for the testCollect a clean catch urine sample 3 hours after the last voiding. The first morning voided specimen should not be used.
If the collection is being taken from an infant, a couple of extra collection bags may be necessary.
How the test will feelThere is no discomfort associated with a clean catch urine specimen.
Why the test is performedThe test is performed to detect cancer and inflammatory diseases of the urinary tract. The test is often performed when bladder lesions are noted on an X-ray . The test may occasionally be performed in individuals who are at high risk of developing bladder cancer. The test can also detect cytomegalovirus and other viral diseases.
Normal ValuesThe urine shows normal epithelial cells and is relatively free of debris.
What abnormal results meanThere may be an abundance of epithelial cells, red blood cells, white blood cells, or atypical-looking cells. Cancer cells may be present. The results can imply cancer or inflammation of the urinary tract (such as glomerulonephritis ).
Renal cell carcinoma is an additional condition under which the test may be performed.
Special considerationsThe diagnosis of cancer or inflammatory disease cannot be made exclusively by this test. The results are confirmed by other diagnostic tests or procedures.
