This test is ideal if you're experiencing low energy, decreased sex drive, difficulty building muscle, or unexplained fatigue. It measures free testosterone, which is the active form of testosterone your body can actually use for energy, muscle growth, and overall vitality. Many men use this test when they suspect hormonal imbalance is affecting their performance, mood, or physical health but want precise answers.
If you're using a testosterone cream, make sure you haven't applied any to the inner elbow area of your arm for at least 24 hours before your blood draw, as this can artificially elevate your results. No fasting is required for this test. The LC/MS/MS method used provides highly accurate results, and confirmation testing may extend turnaround time if needed.
This test measures free testosterone, which is the biologically active form of testosterone not bound to proteins in your blood. Unlike total testosterone, free testosterone reflects how much of the hormone is actually available for your body to use for building muscle, maintaining energy, supporting libido, and regulating mood. This specific measurement is especially valuable when other factors like obesity, thyroid issues, or liver conditions might affect protein binding and make total testosterone levels misleading.
