|Clinical Use:||To investigate delayed or precocious puberty. diagnosis of a virilising adrenal tumour and monitoring recurrence after surgical removal. Differential diagnosis of Cushing’s syndrome due to an adrenal adenoma.|
|Background:||The assay has little value in the investigation of acne, idiopathic hirsutism or infertility. Virilising adrenal tumours – These are often associated with an increased production of dehydroepiandrosterone sulphate which can be detected by analysis of serum or urine.

Cushing’s syndrome – Serum values below the normal reference range have been described in patients with cortisol excess due to adrenal adenoma.
|Reference Ranges:||2.7 – 9.2 µmol/L|
|Patient Preparation:||None required|
|Specimen Requirements:||A serum sample (SST) is required for analysis|
