OBJECTIVE: To compare 2 methods of fixation in bloody Pap smears with Carnoy's solution and 96% ethyl alcohol. STUDY DESIGN: After observation of contact bleeding, 2 samples were prepared from cervical cells with conventional Pap smear. One sample was fixed in 96% ethyl alcohol and another sample was fixed in Carnoy's solution. RESULTS: Of 450 slides, 410 were selected for study. In study of cell adequacy, diagnosis of squamous cells and glandular cells was better in Carnoy's-fixed slides. Blood contamination of slides was reduced in Carnoy's-fixed slides (13.85% vs. 49.51%), and clearance of slides was increased in Carnoy's-fixed slides. Diagnosis of inflammatory cells and pathogenic microorganisms in was increased in Carnoy's-fixed slides, but no difference was seen in diagnosis of epithelial cell and glandular cell abnormalities. CONCLUSION: Carnoy's solution can be used as an effective fixative in bloody smears in conventional Pap tests.
