Enhance Free Testosterone Testing with Direct Detection
Eliminate extra steps, save time and money.
Davis, CA, September 5th, 2012 – 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 Free Testosterone products save time and money while reducing the possibility of errors.
Reduce errors and cost with single-step Free Testosterone…
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.
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.
