Product Description

Competitive immunoenzymatic colorimetric method for the quantitative determination of Androstenedione concentration in human serum or plasma. Androstenedione ELISA kit is intended for laboratory use only.

Scientific Description
Androstenedione (also known as Δ4-androstenedione) is a steroid hormone produced in the adrenal glands and the gonads by the action of 17,20-lyase on either DHEA (principle pathway) or 17 a-hydroxyprogesterone (secondary pathway).  Adrenal production of androstenedione is controlled by adrenocorticotrophic hormone (ACTH) and gonadotrophins control production from the gonads.  It is a critical precursor of both the androgen and oestrogen sex hormones acting as an endogenous prohormone; additionally, androstenedione also exhibits weak androgenic activity.  In females, conversion of androstenedione produces approx. 50% of the body’s testosterone and almost all the oestrogen; conversely in males most androstenedione is directly converted to testosterone with little being secreted into the bloodstream.  Measurement of serum androstenedione therefore provides a useful marker of androgen biosynthesis1.
Measurement of androstenedione is useful in several clinical settings: Diagnosis and differential diagnosis of hyperandrogenism, diagnosis of premature adrenarche and diagnosis of congenital adrenal hyperplasia (CAH) and monitoring of CAH therapy.  It has been suggested that measurement of androstenedione levels, together with 17-hydroxyprogesterone and cortisol, constitute the best screening tool for diagnosis of CAH2.  Elevated androstenedione levels have been demonstrated in virilising CAH, polycystic ovary syndrome and may also occur in adrenal and ovarian virilising tumours.
