How accurate is cytology?
The sensitivity of voided urine cytology for detection of urothelial neoplasm ranges from 18% to 76% and is dependent on factors such as tumor grade, the number of specimens examined, and the expertise of the cytopathologist.
Specificity of urine cytology specimens have been reported to be as high as 93%..
Is biopsy more accurate than cytology?
Like many types of medical tests, a cytology test can give a false negative or false positive result.
Additionally, in some cases, tissue biopsies can be more accurate than cytology tests..

Why is cytology preferred?
It's mainly used to diagnose or screen for cancer.
It's also used to screen for fetal abnormalities, for pap smears, to diagnose infectious organisms, and in other screening and diagnostic areas..
- The moderate sensitivity of cytology is complemented by its high specificity (range of most studies: 95% to 100%).
False-positive results, in other words, are uncommon.
Some investigators report finding no false-positive results in their studies34,42; others describe rates ranging from 1.3% to 15%.
