Methods: There were 249 patients who participated in the study. Of these, 6/249 (2.4%) turned out positive in papsmear, 7/249 (2.8%) turned out positive in liquid based cytology while 23/249 (9.2%) turned out positive in visual inspection with acetic acid. Colposcopic guided cervical biopsy was done on all 249 patients to confirm the results.
Results: Fourteen turned out positive for cervical intraepthelial neoplasia, 1 patient had carcinoma in situ and 1 was positive for squamous cell carcinoma.
Conclusion: Among the three screening tests, VIA appears to be the most accurate, followed by liquid based cytology as compared to the conventional papsmear.
