A repeat Pap smear may be necessary for several reasons:
1. Inadequate Sample: Sometimes, the initial sample may not contain enough cells or may be obscured by blood or mucus. 2. Borderline Abnormalities: If the initial test shows borderline or inconclusive results, a repeat test can help clarify the findings. 3. Follow-Up of Abnormal Results: If the first Pap smear indicates abnormal cells, a repeat test may be required to monitor changes or confirm the diagnosis. 4. Screening Recommendations: Based on age and medical history, some guidelines recommend more frequent screening.
