Diagnosis and differential diagnosis of hyperandrogenism (in conjunction with measurements of other sex-steroids). An initial workup in adults might also include total and bioavailable testosterone (TTBS/80065 Testosterone, Total and Bioavailable, Serum) measurements. Depending on results, this may be supplemented with measurements of sex hormone-binding globulin (SHBG Sex Hormone Binding Globulin [SHBG], Serum) and other androgenic steroids (eg, dehydroepiandrosterone sulfate [DHEA-S]).
Diagnosis of congenital adrenal hyperplasia (CAH), in conjunction with measurement of other androgenic precursors, particularly, 17-alpha-hydroxyprogesterone (OHPG) (OHPG/9231 17-Hydroxyprogesterone, Serum), 17 alpha-hydroxypregnenolone, DHEA-S (DHES Dehydroepiandrosterone Sulfate [DHEA-S], Serum), and cortisol (CORT Cortisol, Serum).
Monitoring CAH treatment, in conjunction with testosterone (TTST Testosterone, Total, Serum), OHPG, DHEA-S (DHES Dehydroepiandrosterone Sulfate [DHEA-S], Serum), and DHEA (DHEA_/81405 Dehydroepiandrosterone [DHEA], Serum).
Diagnosis of premature adrenarche, in conjunction with gonadotropins (FSH Follicle-Stimulating Hormone [FSH], Serum; LH Luteinizing Hormone [LH], Serum) and other adrenal and gonadal sex-steroids and their precursors (TTBS/80065 Testosterone, Total and Bioavailable, Serum or TGRP/8508 Testosterone, Total and Free, Serum; EEST/81816 Estradiol, Serum; DHES Dehydroepiandrosterone Sulfate [DHEA-S], Serum; DHEA_/81405 Dehydroepiandrosterone [DHEA], Serum; SHBG Sex Hormone Binding Globulin [SHBG], Serum; OHPG/9231 17-Hydroxyprogesterone, Serum).
