What can a testosterone profile blood test tell you?

Free testosterone, also called unbound testosterone, refers to the amount of testosterone available for your body to use - so is a more useful indicator than total testosterone alone.

Your testosterone levels can affect your energy, mood, muscle and bone strength, sex drive, cognitive function, and fertility. If you're having issues in any of these areas, this test will indicate whether your testosterone profile could be a contributing factor.

Testosterone profile (free or unbound)

Testosterone is essential for your sex drive, bone and muscle health, mood, and cognitive function. Your levels gradually drop as you age. If your levels are out of range you might feel tired, have a low sex drive, and have low mood. Measuring free (or unbound) testosterone gives you a more detailed picture of the testosterone available for your body to actually use.
