Simplify and improve your clinical laboratory with single-step, direct ELISA measurement of Free Testosterone from Gold Standard Diagnostics (GSD). Compared to indirect, multi-step testing algorithms, GSD’s FDA Cleared Free Testosterone products save laboratories time and money while reducing the possibility of errors.
The ability to directly measure Free Testosterone eliminates the complication of taking multiple indirect measurements and calculating Free Testosterone through an algorithm. Diagnostic technologies have inherent limitations in terms of both precision and accuracy. Combining multiple procedures exacerbates these limitations and increases both the cost and opportunity for errors.
Develop the complete picture with Total Testosterone
The combination of Free and Total Testosterone gives healthcare professionals more information to make the correct diagnosis when a Testosterone-related condition is suspected. Gold Standard Diagnostics also offers an ELISA test for Total Testosterone level to complement the Free Testosterone assay.
Fully automate Testosterone testing with the ThunderBolt®
Through a host of patent-pending features, the ThunderBolt® delivers exceptional power and flexibility in a small size. The dual function analyzer provides complete, walk-away automation of 192 patient samples in only a 2’ by 2’ space. Completely open architecture allows any EIA or CLIA protocol to be programmed, and up to eight different protocols to run in a single batch. Intuitive and robust software further enriches the ThunderBolt®, making it the total laboratory automation solution.
GSD’s Free and Total Testosterone assays are fully validated as ThunderBolt-Ready, ensuring quick, easy and effective implementation for any laboratory environment.
Why Free and Total Testosterone levels matter
Total Testosterone measures levels of all forms in the blood stream, including: unbound (free), loosely bound to albumin and tightly bound to sex-hormone binding globulin (SHBG). Many common factors influence SHBG levels. As a result, a Total Testosterone assessment may yield a normal result, but due to higher or lower levels of Testosterone-SHBG bonding, the concentration of Free Testosterone may not correlate directly with Total Testosterone readings.
SHBG levels can be increased by factors such as obesity and testosterone treatment. Factors that can decrease SHBG levels include aging, pregnancy and estrogen therapy. Symptoms of low testosterone in males include decreased sexual function, erectile dysfunction, loss of hair, decreased muscle mass and osteoporosis. For females, symptoms include hot flashes, irritability, decreased libido and insomnia.
