Free & Total Testosterone Blood Test
Testosterone plays a vital role in energy levels, muscle strength, mood, fertility, and sexual health. Low testosterone (sometimes called “Low T”) can lead to symptoms such as fatigue, reduced strength, weight changes, or decreased libido.
Our Free & Total Testosterone Blood Test measures both:
-
Total testosterone – the overall level circulating in your bloodstream.
-
Free testosterone – the active form available for your body to use.
By assessing both, you will gain a clearer understanding of your hormone balance and how it may be affecting your health and well-being. This test is ideal for anyone experiencing symptoms of low testosterone, exploring fertility concerns, or monitoring hormone therapy.
It's easy and simple to use.

4 Biomarkers covering Total Testosterone, Free Testosterone, Albumin, and SHBG (Sex Hormone-Binding Globulin).
Biomarkers Explained
1. Total Testosterone
This measures the overall amount of testosterone in your blood. Most of it is bound to proteins (like SHBG and albumin), and only a small fraction is active. Total testosterone is a good starting point for understanding your hormone health.
2. Free Testosterone
This is the small portion of testosterone that is not bound to proteins and is freely available for your body to use. Free testosterone is considered the biologically active form, directly influencing things like energy, mood, muscle mass, and sex drive.
3. Albumin
Albumin is a protein made by the liver. Some testosterone binds loosely to albumin in the blood. While this form is not “free,” it can still be released and used by the body when needed. Albumin levels also provide important context for understanding hormone balance and overall health.
4. SHBG (Sex Hormone-Binding Globulin)
SHBG is a protein that binds tightly to testosterone and carries it through the bloodstream. Testosterone bound to SHBG is not available for the body to use. High or low SHBG levels can affect how much free testosterone is available, so measuring SHBG helps give a clearer picture of your true hormone status.

FAQ – Testosterone Blood Tests
If you have any other questions reach out to us directly!
1. What is testosterone and why is it important?
Testosterone is a hormone that plays a key role in energy, mood, muscle strength, fertility, and sexual health. Both men and women produce testosterone, although at different levels. Balanced testosterone is essential for overall well-being.
2. What’s the difference between Total Testosterone and Free Testosterone?
Total Testosterone measures the overall amount of testosterone in your blood, most of which is bound to proteins.
Free Testosterone measures the unbound, active form of testosterone that is available for your body to use.
Testing both together provides the most complete picture of hormone health.
3. Who should consider a testosterone test?
You may benefit from testing if you are experiencing symptoms such as:
- Low energy or fatigue
- Reduced muscle mass or strength
- Changes in mood or concentration
- Low sex drive
- Fertility concerns
4. How is the test done?
The test requires a simple blood sample, which is analysed in our CQC certified laboratory. Depending on the option, this may be collected with a finger-prick kit at home kit or via a venous blood draw.
5. Do I need to fast before the test?
In most cases, fasting is not required. However, testosterone levels can fluctuate during the day, so it is generally recommended to take the test in the morning for the most accurate results.
6. How long will it take to get my results?
Once your sample reaches the lab, results are typically available within a five working days. You will receive a clear, easy-to-understand report.
7. Can women take a testosterone test?
Yes. Although testosterone is often thought of as a male hormone, it also plays an important role in women’s health, including fertility, bone strength, energy, and libido.
8. What if my results show low testosterone?
If your results suggest low or imbalanced testosterone, it’s important to discuss them with a healthcare professional. They can help determine whether further testing, lifestyle changes, or treatment is needed.
9. Is this test suitable for monitoring hormone therapy?
Yes, both Total Testosterone and Free & Total Testosterone tests are commonly used by people monitoring testosterone replacement therapy (TRT) or other hormone-related treatments.
10. How accurate are the results?
All samples are processed by accredited laboratories using validated methods, ensuring reliable and clinically accurate results.
