Blood Test for Acne

Blood Test for Acne

A blood test for acne investigates the hormonal causes of persistent breakouts—including elevated androgens (testosterone, DHEA-S), polycystic ovary syndrome (PCOS), cortisol imbalances from stress, and insulin resistance—because adult acne that doesn't respond to topical treatments often has a hormonal root cause that can be addressed.

At Blood Test London, our acne hormone panel costs from £295 with results in 2-3 days. A doctor always reviews every result.
