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.
