How Is Acne Diagnosed?
A comprehensive clinical assessment for acne goes beyond a visual inspection. Clinicians use validated visual tools, such as the Global Acne Grading System (GAGS), to score lesion types, counts, and anatomical distribution. Establishing this baseline severity grade allows the clinician to map out a structured treatment strategy and objectively track progress over time.
During diagnosis, the clinician will also:
- Evaluate your overall skin barrier health and baseline skin type (oily, dry, combination, or sensitive).
- Assess the presence of active tissue damage or early structural scarring.
- Review your historical response to past skincare formulations and medical treatments.
Routine blood panels are unnecessary for most straightforward acne cases. However, blood tests may become clinically relevant when prescribing certain oral medications such as isotretinoin, or when investigating potential endocrine conditions in adult women presenting with treatment-resistant acne.
