Diagnosis of patients with even mild hirsutism should include assessment of ovulation and ovarian ultrasound , due to the high prevalence of polycystic ovary syndrome (PCOS) , as well as 17α-hydroxyprogesterone (because of the possibility of finding nonclassic 21-hydroxylase deficiency [14] ). Many women present with an elevated serum dehydroepiandrosterone sulfate (DHEA-S) level. Levels greater than 700 μg/dL are indicative of adrenal gland dysfunction, particularly congenital adrenal hyperplasia due to 21-hydroxylase deficiency . [12] However, PCOS and idiopathic hirsutism make up 90% of cases. [12]

Denatured TBG does not bind iodothyronines but can be detected with antibodies that recognize the primary structure of the molecule (23).  In euthyroid adults with normal TBG concentration, about one-third of the molecules carry thyroid hormone, mainly T4.  When fully saturated, it carries about 20 µg of T4/dl of serum.  The biologic half-life is about 5 days, and the volume of distribution is similar to that of albumin (34,35) (Table 1).  TBG is cleared by the liver.  Loss of sialic acid accelerates its removal through interaction with the asialo-glycoprotein receptors reducing the half live by 500-fold (21).  However, it is unknown whether desialylation is a required in the normal pathway of TBG metabolism.
