Why this test
Androstenedione sits at the crossroads of adrenal and gonadal androgen production. Testosterone is the first-line androgen test, so androstenedione is read alongside testosterone and SHBG, and sometimes DHEA-S, rather than on its own.
Androstenedione is an androgen precursor produced by both the adrenal glands and ovaries (in women) or testes (in men). It can be converted into testosterone and oestrogen. A raised level is one of the androgen findings a doctor may look at when investigating polycystic ovary syndrome (PCOS) or conditions affecting the adrenal glands, and a single result does not confirm a diagnosis on its own. Guidelines place testosterone first when androgen excess is being looked into. Androstenedione and DHEA-S are additional tests a doctor may consider when testosterone is not raised.
Understanding your results
Reference ranges differ by sex and age — see your full report for lab-specific context
Within normal limits — sex and age-specific ranges apply
Low androstenedione is uncommon outside of adrenal insufficiency — discuss with your healthcare practitioner if unexpected
Elevated androstenedione may warrant further investigation of adrenal or ovarian androgen sources — discuss with your healthcare practitioner
Reference ranges vary by laboratory and personal context. Your result is shown against the lab's range in your dashboard, alongside what it means.
