What's this test for?
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.
How should I prepare for this test?
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.
What's included in this test?
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.
What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your free testosterone level means for your energy, muscle mass, libido, and overall health. These notes include personalized recommendations like lifestyle changes, supplement suggestions, or whether you should consider further evaluation for hormone therapy. You'll also get the standard lab report and can track your testosterone levels over time using our trends feature to see how your interventions are working.
When will I get my results?
You can expect your results in approximately 7 business days after your blood sample reaches the lab. If confirmation testing is required to ensure accuracy, the timeline may be extended slightly. You'll be notified via email as soon as your results are ready to view in your secure account.
Who should consider getting this test?
This test is ideal for men experiencing symptoms of low testosterone like fatigue, reduced muscle mass, low libido, or difficulty concentrating. It's also valuable for women dealing with hirsutism (excess hair growth) or masculinization symptoms. Additionally, people with conditions that affect hormone-binding proteins—such as obesity, thyroid disorders, or liver disease—should consider this test for more accurate testosterone assessment.
What symptoms indicate I may need this test?
Common symptoms include persistent fatigue that doesn't improve with rest, decreased sex drive, difficulty building or maintaining muscle mass despite exercise, increased body fat (especially around the midsection), mood changes like irritability or low motivation, and reduced physical stamina. For women, symptoms might include unwanted facial or body hair growth, irregular periods, or deepening voice.
How can I naturally support my testosterone levels?
Focus on resistance training and high-intensity interval training to naturally boost testosterone production. Prioritize 7-9 hours of quality sleep each night, as testosterone is primarily produced during sleep. Include zinc and magnesium-rich foods like oysters, beef, pumpkin seeds, and spinach in your diet, and maintain a healthy body weight since excess fat can lower testosterone levels.
What is free testosterone and why does it matter?
Free testosterone is the small percentage of testosterone in your blood that isn't bound to proteins, making it immediately available for your body to use. While total testosterone measures all the testosterone in your blood, free testosterone shows how much is actually active and usable. This matters because you can have normal total testosterone but still have symptoms if too much is bound to proteins and unavailable for your cells.
How often should I retest my free testosterone?
If you're starting lifestyle changes or supplements to boost testosterone, retest in 3-6 months to see if your interventions are working. If you're on testosterone replacement therapy or being treated for hormone issues, your doctor may recommend testing every 3-4 months initially, then every 6-12 months once levels stabilize. For general wellness monitoring, annual testing is reasonable if you have symptoms or risk factors.

What this means
Your free testosterone level is slightly below the optimal range. While this is not necessarily cause for immediate concern, it may contribute to symptoms like occasional fatigue, reduced motivation, difficulty building muscle, or decreased libido. This level suggests your body may benefit from targeted lifestyle interventions to optimize hormone production.
Recommended actions
Increase resistance training or weightlifting 3-4 times per week
Prioritize 7-9 hours of quality sleep per night and manage stress levels
Include more zinc- and magnesium-rich foods like shellfish, beef, pumpkin seeds, and spinach
Consider retesting in 3-6 months to monitor progress after lifestyle changes
* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More complex tests, such as hormone panels, may take up to 10–15 business days due to their complexity.
