Intended Use

A Second Opinion, Not a Final Diagnosis

HerLens provides AI-assisted insights to support healthcare workers' decisions. The final assessment remains with the healthcare worker.

  • VIA Positive

    AI indicates potential abnormal findings that may require further clinical assessment.

  • VIA Negative

    AI indicates no detected abnormal findings, supporting the healthcare worker's evaluation.

Confidence Level

Supporting Decisions with Confidence

HerLens provides confidence levels with every AI result, helping healthcare workers understand AI certainty before making clinical decisions.

  • High Confidence (≥80%)

    Strong AI indication with higher certainty.

  • Moderate Confidence (50–79.9%)

    AI detects potential findings but requires careful clinical review.

  • Low Confidence (<50%)

    AI has limited certainty and requires closer clinical review.
