Introduction: In many endocrine centres the 250μg Short Synacthen (Cosyntropin) Test (SST) is the reference standard for the diagnosis of adrenal insufficiency (AI) 1, but it is time consuming, expensive, and requires hospital attendance and venepuncture. The morning physiological peak of cortisol shortly after waking is a good predictor for a negative SST; however, a morning serum cortisol requires venepuncture. Serum cortisol and salivary cortisone correlate ...

Introduction: The 250µg Short Synacthen test (SST) is the reference standard for a diagnosis of adrenal insufficiency (AI) in most endocrine centres. The test is expensive and time consuming, requiring clinic attendance. We hypothesised that a cheaper home waking salivary cortisone (WSC) is predictive of the SST 30-minute cortisol >430 nmol/l cut-off and carried out a diagnostic accuracy study to assess the predictive value of the WSC in diagnosing and excluding AI. W...
