## Indications for use
The ADVIA Centaur® Testosterone II (TSTII) assay is for in vitro diagnostic use in the quantitative determination of total testosterone (bound and unbound) in human serum and plasma using the ADVIA Centaur XP system. Measurements of testosterone are used in the diagnosis and treatment of disorders involving the male sex hormones (androgens), including primary and secondary hypogonadism, delayed or precocious puberty, impotence in males and, in females, hirsutism (excessive hair) and virilization (masculinization) due to tumors, polycystic ovaries, and adrenogenital syndromes. ADVIA Centaur® SHBG The ADVIA Centaur® SHBG assay is an in vitro diagnostic immunoassay for the quantitative determination of sex hormone-binding globulin (SHBG) in human serum and plasma using the ADVIA Centaur XP system. The ADVIA Centaur SHBG assay is intended for use as an aid in the diagnosis of androgen disorders.
