With more than 20 years of experience and continuous innovation, we have created the most advanced system for measuring and understanding steroid hormones. Our sophisticated and precise chromatography-mass spectrometric techniques quantitatively evaluate endogenous steroids in various biological specimens, such as tissue, urine, blood, saliva and hair. Our proven assays have enabled basic scientists and clinicians to make novel discoveries—revealing critical insights that have advanced scientific research around the world.
