A free testosterone blood test determines the amount of unbound or “free” testosterone in your system.
Is it for me?
What you should know about the free testosterone blood test:
Bound and Free Testosterone: There are two types of testosterone in the bloodstream: bound and free. Bound testosterone binds to proteins, most notably sex hormone-binding globulin (SHBG) and albumin. Free testosterone is the biologically active version of the hormone since it is not attached to proteins. This free testosterone is what is available to affect various physiological systems.
Hormonal Balance: Hormonal balance is essential for good health and well-being. Men require testosterone to maintain muscle mass, bone density, libido, and other facets of male health. It also helps women maintain bone health, muscle mass and general vigour.
Diagnosis and Monitoring: The free testosterone blood test is routinely used to diagnose and monitor hormonal imbalance-related diseases.
Assessing Hormonal Therapy: The test is also used to evaluate the effects of testosterone replacement therapy in males with low testosterone levels.
Normal Range: The normal range for free testosterone levels varies depending on age, gender, and the laboratory’s reference values.
