Additional Testing Requirements


For diagnosis and differential diagnosis of hyperandrogenism, an initial workup in adults should also include total and bioavailable testosterone (TTBS / Testosterone, Total and Bioavailable, Serum) measurements. Depending on results, this may be supplemented with measurements of sex hormone-binding globulin (SHBG1 / Sex Hormone-Binding Globulin, Serum) and other androgenic steroids (eg, dehydroepiandrosterone sulfate [DHEA-S]).

 

For diagnosis of congenital adrenal hyperplasia (CAH), the following assays should also be ordered:

-OHPG / 17-Hydroxyprogesterone, Serum

-DHES1 / Dehydroepiandrosterone Sulfate, Serum

-CORT / Cortisol, Serum

 

For monitoring CAH treatment, the following assays should also be ordered:

-TTST / Testosterone, Total, Mass Spectrometry, Serum

-OHPG / 17-Hydroxyprogesterone, Serum

-DHES1 / Dehydroepiandrosterone Sulfate, Serum

-DHEA_ / Dehydroepiandrosterone (DHEA), Serum.

 

For diagnosis of premature adrenarche, the following assays should also be ordered:

-FSH / Follicle-Stimulating Hormone (FSH), Serum

-LH / Luteinizing Hormone (LH), Serum

-TTBS / Testosterone, Total and Bioavailable, Serum or TGRP / Testosterone, Total and Free, Serum

-EEST / Estradiol, Serum

-DHES1 / Dehydroepiandrosterone Sulfate, Serum

-DHEA_ / Dehydroepiandrosterone (DHEA), Serum

-SHBG1 / Sex Hormone-Binding Globulin, Serum

-OHPG / 17-Hydroxyprogesterone, Serum
