What does the Free and Bioavailable Testosterone test measure?
This test measures the free and bioavailable forms of testosterone in your blood. These are the active forms of the hormone that your body can actually use. Measuring these levels can provide a more precise understanding of how testosterone is functioning in the body.
How is this test different from a total testosterone test?
A total testosterone test measures all testosterone in the blood, including the portion bound to proteins. The Free and Bioavailable Testosterone test focuses on the testosterone that is not tightly bound and is available for the body to use. This can provide clearer insight into symptoms related to hormone imbalance.
What symptoms might lead someone to consider this test?
Symptoms that may be associated with testosterone imbalance include fatigue, decreased muscle mass, changes in weight, increased body fat, hair loss or abnormal hair growth, changes in sleep, difficulty concentrating, depression, and low libido or erectile dysfunction.
Why is free and bioavailable testosterone important for fertility?
Testosterone plays an important role in sperm production and libido. Measuring the active forms of testosterone can provide helpful information when evaluating reproductive health and fertility.
When is the best time to take this test?
Testosterone levels decline throughout the day, so it is recommended to take this test first thing in the morning to obtain the most accurate results.
