The ARCHITECT 2nd Generation Testosterone assay is a chemiluminescent microparticle immunoassay (CMIA) for the quantitative determination of testosterone in human serum and plasma. 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.
The ARCHITECT 2nd Generation Testosterone Calibrators are for the calibration of the ARCHITECT i System when used for the quantitative determination of testosterone in human serum and plasma.
The ARCHITECT 2nd Generation Testosterone Controls are for the verification of the accuracy and precision of the ARCHITECT i System when used for the quantitative determination of testosterone in human serum and plasma.
Indications for use as stated in the FDA summary.
