Objective:

To evaluate the accuracy of HPV testing from menstrual blood as a non-invasive alternative for cervical cancer screening.

Approach:

Key Findings:

• Menstrual blood testing can detect high-risk HPV with accuracy comparable to clinician-collected cervical samples.
• High negative predictive value for high-grade cervical lesions was observed with menstrual blood samples.
• Menstrual blood testing showed slightly lower specificity than clinician sampling, but referral rates for follow-up were comparable.

Interpretation:

Menstrual blood testing offers a promising non-invasive method for HPV screening that aligns with normal physiological processes, potentially increasing participation in cervical cancer prevention.

Limitations:

• Slightly lower specificity compared to clinician-collected samples.
• Potential challenges in acceptance and implementation in various populations.

Conclusion:

If widely adopted, menstrual blood HPV testing could enhance screening coverage, particularly in low-resource settings, by allowing home-based sample collection without invasive procedures.
