Testosterone Test

A focused 4-marker testosterone panel measuring total testosterone, free testosterone, and SHBG. Provides the key data points needed to assess bioavailable testosterone — the fraction that actually affects your tissues and determines how you feel and perform.

Total testosterone alone tells an incomplete story. SHBG (sex hormone-binding globulin) binds testosterone in the bloodstream, making it unavailable to tissues. Two men with identical total testosterone can have very different free testosterone levels depending on their SHBG — and it is free testosterone that drives the effects most people associate with the hormone: energy, muscle growth, libido, mood, and cognitive function. This panel measures all three markers to give a complete picture of testosterone availability. SHBG levels are influenced by age, body fat, thyroid function, insulin resistance, and medications — making this measurement clinically important for interpreting the results in context. At $99, this is one of the most affordable ways to get a comprehensive testosterone assessment in Australia without a GP referral. It serves as an excellent screening tool that can determine whether further investigation into the broader hormonal picture is warranted.
