This Testosterone Panel Includes 5 Tests: Total Testosterone (LC/MS most accurate assay), Free Testosterone, Bioavailable Testosterone (Free T plus albumin-bound T), Sex Hormone Binding Globulin (SHBG), and Albumin. Good for men who expect high T levels and for women (panel is also accurate for lower T levels).


At DiscountedLabs.com, we understand the importance of hormone balance and its impact on your overall well-being. That's why we offer the Comprehensive Testosterone Test Panel, an advanced diagnostic tool designed to provide a complete understanding of your testosterone levels.

Our Bioavailable Testosterone Test Panel is a unique set of five crucial tests that provide a detailed analysis of different testosterone components. Suitable for both men and women, this panel is specifically designed to cater to the needs of those with high testosterone levels.

1. Testosterone, Total, LC/MS

  • Ideal for: Men with high testosterone and women
  • Method: Liquid Chromatography-Mass Spectrometry (LC/MS)
  • Description: This test measures the total testosterone in your blood, without an upper or lower limit. The LC/MS method ensures the most accurate reading, essential for understanding the overall testosterone status.

2. Testosterone, Free

  • Method: Calculated based on LC/MS/MS-derived total testosterone and equilibrium dialysis-derived percent free levels.
  • Description: Free testosterone accounts for the unbound and bioactive portion of testosterone in your system. This measurement is vital for evaluating hormonal balance and potential deficiency or excess.

3. Testosterone, Bioavailable

  • Method: Calculated using LC/MS/MS-derived total testosterone, equilibrium dialysis-derived percent free testosterone levels, albumin, and SHBG.
  • Description: Bioavailable testosterone represents the portion of testosterone that is readily available to the body's tissues. This precise calculation offers insight into your hormonal state and how it may affect your health.

4. Sex Hormone Binding Globulin (SHBG)

  • Description: SHBG is a protein that binds to sex hormones, including testosterone. By understanding the levels of SHBG, we can interpret how much testosterone is available for the body to utilize. It plays a vital role in determining the effectiveness of hormone replacement therapy or identifying hormonal imbalances.

5. Albumin

  • Description: Albumin is a protein found in blood plasma that helps to transport hormones like testosterone. Measuring albumin levels is essential in calculating bioavailable testosterone and aids in the understanding of overall metabolic and liver health.
