This Free Testosterone Calculator is a reliable tool designed to estimate your free and bioavailable testosterone levels based on your total testosterone, SHBG, and albumin values.

Utilizing the Vermeulen formula, it provides a more accurate reflection of the bioactive testosterone in your system compared to total testosterone measurements alone.

What is Testosterone?

Testosterone is a vital hormone predominantly found in males, playing a crucial role in muscle mass, bone density, and overall well-being

While total testosterone measures the overall amount in the bloodstream, it doesn’t differentiate between active and inactive forms

Free vs. Bioavailable Testosterone

• Free Testosterone: This is the unbound form of testosterone, readily available for the body to use.
• Bioavailable Testosterone: Includes free testosterone and testosterone weakly bound to albumin, both accessible for biological activity

Measuring these forms provides a clearer picture of hormonal health, especially when total testosterone levels are borderline or don’t align with clinical symptoms.

Importance of Accurate Measurement

Traditional total testosterone tests may not always reflect the active hormone levels in the body. Factors like SHBG and albumin can influence the amount of testosterone that’s actually available for use

Therefore, assessing free and bioavailable testosterone offers a more comprehensive understanding, aiding in accurate diagnosis and treatment planning.

How the Calculator Works

The calculator employs the Vermeulen formula, a widely accepted method in clinical settings, to estimate free and bioavailable testosterone levels .

By inputting your total testosterone, SHBG, and albumin values, the calculator provides immediate results, helping you and your healthcare provider make informed decisions.
