In women, one half of androstendione originates from the adrenal cortex and the other half from the ovaries. As a supplementary parameter to the more important hormones testosterone and DHEA-S, the test is only of limited significance for the diagnostic assessment of a hyperandrogenaemia in women. The determination in men is only appropriate in special cases. |
Further tests: | For the diagnostic assessment of a hyperandrogenaemia in women: Testosterone, LH, FSH, oestradiol, SHBG, DHEA-sulphate, TSH, prolactin. |
