The measurement of Δ4-androstenedione is used in the diagnosis and differential diagnosis of androgen overproduction (hyperandrogenism - in combination with measurements of other steroid hormones), in the diagnosis and monitoring of congenital adrenal hyperplasia and in the diagnosis of premature ejaculation androgens in children.

Δ4-androstenedione is mainly secreted by the adrenal glands and its production is controlled, at least in part, by the corticospinal tract (ACTH). It is also produced, independently of ACTH, in the testes and ovaries by DHEA-S secreted by the adrenals. Androstenedione is an essential precursor molecule in the synthesis of steroid hormones.

Elevated androstenedione levels can cause symptoms or signs of hyperandrogenism in women. Men are usually asymptomatic, but because of the peripheral (in adipose tissue and liver) conversion of androgens to estrogens, mild symptoms of elevated estrogen concentrations, such as gynecomastia, can sometimes be observed.

Most mild to moderate elevations of Δ4-androstenedione are idiopathic or related to conditions such as polycystic ovary syndrome. However, large increases in androstenedione may be indicative of adrenal or gland tumors (ovarian and testicular). If for any reason, the production of androstenedione increases in a child, premature sexual development may occur. In postmenopausal women, increased production of androstenedione can lead to bleeding, endometriosis, ovarian stimulation and polycystic ovaries.

Increased production of androstenedione in obesity can cause menstrual abnormalities in women and signs of feminization such as gynecomastia in men. Determination of Δ4-androstenedione is useful in the diagnosis of menstrual abnormalities, early sexual development and postmenopausal abnormalities.

Important Note

Laboratory test results are the most important parameter for the diagnosis and monitoring of all pathological conditions. 70%-80% of diagnostic decisions are based on laboratory tests. Correct interpretation of laboratory results allows a doctor to distinguish "healthy" from "diseased".

Laboratory test results should not be interpreted from the numerical result of a single analysis. Test results should be interpreted in relation to each individual case and family history, clinical findings and the results of other laboratory tests and information. Your personal physician should explain the importance of your test results.

At Diagnostiki Athinon we answer any questions you may have about the test you perform in our laboratory and we contact your doctor to get the best possible medical care.
