About Pap Test
The Pap test is a non-sterile cellular specimen obtained for microscopic examination to screen for abnormal cellular changes suggestive of cancer and its precursor conditions. The State Laboratory of Public Health accepts only gynecological ThinPrep Pap specimens from local health departments and state-operated health facilities (public health patients). The Pap test is a screening test for an asymptomatic population. Symptoms, which may be due to neoplasia, should be completely evaluated: the Pap test in this situation is not appropriate management.
False negative tests may occur due to sampling errors, screening difficulties inherent in Pap tests or due to the subjective nature of cytodiagnosis. Patients should have Pap test done on a routine basis.
