What This Test Checks For
Total testosterone measures every form of testosterone in your blood—both the small amount that's free and active and the larger portion bound to proteins like SHBG and albumin.
Reference ranges typically run 300-1,000 ng/dL for adult men and 10-70 ng/dL for women.
Free testosterone is the roughly 2-3% that's unbound and biologically active—the part your body can actually use. Two people can have identical total testosterone but very different symptoms, because SHBG determines how much of that total is actually available.
SHBG (Sex Hormone-Binding Globulin) is the reason this test includes all three markers together instead of just one.
If SHBG is high, total testosterone can look normal while free testosterone runs low. If SHBG is low, the reverse can happen. Testing all three at once—instead of just total—is what actually tells you whether a low or normal number reflects your real hormonal status.

What's the difference between total and free testosterone? Total measures everything in your blood, including testosterone bound to proteins. Free measures only the small, active fraction your body can actually use — which is why we test both together with SHBG.
