Published studies have shown, however, that many currently available testosterone tests are not sensitive enough to measure low levels of testosterone. This limits the clinical utility of these tests. To address this need and help physicians accurately measure the wide range of testosterone levels seen in men and women, Abbott announced today clearance from the U.S. Food and Drug Administration for a new testosterone test.

"The ARCHITECT 2^nd Generation Testosterone Assay is more sensitive, accurate and precise than previous versions of the assay," said Frank Quinn, PhD, FACB, director of Global Scientific Affairs for Endocrinology, Abbott. "The improved assay performance means physicians will be able to obtain more reliable measurements of testosterone and use this information to help guide patient treatment decisions."

The new assay runs on Abbott's fully-automated ARCHITECT family of analyzers and is available in the United States, as well as in several European countries, Asia Pacific, Latin America, Japan, Africa, the Middle East, and India, pending country registration.

Intended Use
The ARCHITECT 2^nd Generation Testosterone Assay is a chemiluminescent microparticle immunoassay 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, and impotence in males; and
• In females, hirsutism (excessive hair) and virilization (masculization) due to tumors, polycystic ovaries, and androgenital syndromes.
