A Diagnostic Study Using STARD Platform on Liquid-Based Cytology in Cervical Smear and Its Positivity Rate among Females with Abnormal Vaginal Conditions Attending a Tertiary Care Center.

Background: Liquid-based cytology (LBC) is a newer method of preparing cervical cell samples. This technique involves collecting cells in a liquid fixative and preparing and evaluating them.

Aim: This study aims to investigate cervical smears prepared using the Ezi-Prep LBC method and analyze the positivity rate for cervical cancer and assess the diagnostic accuracy of LBC in detecting cervical abnormalities among females with abnormal vaginal conditions attending a tertiary care center.

Materials And Methods: The present diagnostic study was performed in a tertiary care hospital over a period of 1 year (April 1, 2021-November 30, 2021). A total of 230 women, aged 21-70 years, presented at the gynecology outpatient department for either routine cervical screening or with complaints of vaginal bleeding, discharge, or pelvic pain. Cervical smears were prepared using the Ezi-Prep method and stained with ULTRA-PAP stain.

Results: LBC smears are monolayer smears and are without nuclear overlapping with spread over a diameter of 16 mm. Minimum cellular overlapping and crowding were observed in LBC smears. The mean age of the participants was 35.5 ± 5.1 years. The smears were studied by using nine morphological parameters.

Conclusion: The majority of the smears were inflammatory smears. A total of 16 cases and three cases were found to be bacterial vaginosis and candidiasis, respectively. In an 8-month study, HSIL was found in two cases, whereas LSIL was found in only one case. The positivity rate was observed to be 0.9% in HSIL cases and 0.4% in LSIL cases, 0.9% ASC-US case, and 0.4% invasive carcinoma case.
