- Albumin The main protein made by your liver, which helps balance fluids and carries hormones, vitamins, and medications through your blood. Low levels can point to liver, kidney, or nutrition issues.
- Free Testosterone The small portion of your testosterone that's unbound and biologically active, considered a more accurate reflection of usable hormone than total testosterone.
- SHBG (Sex Hormone-Binding Globulin) A protein that binds and transports testosterone and estrogen in your blood, determining how much hormone is 'free' and active. Important for interpreting sex hormone results.
- Testosterone The primary male sex hormone, also present in women in smaller amounts. Evaluated for low testosterone symptoms, fertility, and reproductive hormone imbalances.
