- Uses of This Test
The Testosterone Plus Profile provides a detailed assessment of testosterone status by measuring total testosterone alongside key binding proteins that influence how much testosterone is actually available for the body to use. These results are used together to calculate free (biologically available) testosterone, giving a more accurate picture of testosterone activity than measuring total testosterone alone.
Testosterone plays an important role in sexual health, fertility, energy levels, mood, body composition, and overall wellbeing. However, testosterone in the bloodstream is largely bound to proteins, meaning a “normal” total testosterone result does not always reflect the amount of active testosterone available to tissues. This profile helps clarify testosterone status by assessing both total levels and availability, supporting more informed interpretation when symptoms suggest possible testosterone imbalance.
Why free testosterone matters
Testosterone circulates in the bloodstream largely bound to proteins — mainly sex hormone binding globulin (SHBG) and albumin. Only a small proportion is unbound (or loosely bound) and biologically active.
Measuring total testosterone alone can sometimes be misleading, particularly when SHBG is unusually high or low. By measuring total testosterone, SHBG, and albumin together, this profile provides a clearer view of whether symptoms may relate to low, normal, or high available testosterone, even when total levels appear within range.
This profile is commonly used to support assessment and monitoring of testosterone-related concerns, including:
- Hypogonadism (low testosterone patterns)
- Erectile dysfunction where testosterone status may be a contributing factor
- Male infertility where androgen balance is relevant
- Early or delayed puberty (clinical context-dependent)
- PCOS monitoring in women, where elevated testosterone may be relevant
- Monitoring hormone therapy, including testosterone replacement therapy (TRT)
Important information
Both low and high testosterone can contribute to symptoms and may have long-term health implications. Blood testing is the most reliable way to assess testosterone status. For best accuracy, testosterone testing is typically recommended between 7am and 10am, when levels are naturally highest.
Hypogonadism / Testosterone Deficiency
Low testosterone patterns that may contribute to reduced libido, fatigue, low mood, muscle loss, and fertility concerns.
Erectile Dysfunction
Testosterone imbalance may contribute to sexual function concerns, particularly when libido is affected.
Male Infertility (hormone-related)
Testosterone availability plays a role in reproductive hormone balance and sperm production.
Delayed or Early Puberty (clinical assessment support)
Testosterone measurement may support evaluation of pubertal hormone development when clinically indicated.
Polycystic Ovary Syndrome (PCOS)
In women, elevated testosterone patterns may support assessment or monitoring of PCOS-related hormone imbalance.
Hormone Therapy Monitoring
Supports safe and effective monitoring of testosterone-based therapy to reduce risk of under- or over-treatment.
- Assess biologically active testosterone
- Investigate low libido or sexual health concerns
- Investigate fatigue or low mood linked to hormones
- Support evaluation of suspected low testosterone
- Monitor testosterone replacement therapy (TRT)
- Support fertility-related hormone assessment
What We Test
Biomarkers analysed by accredited UK laboratories
Biomarkers Tested
Androgen Hormones and Binding Proteins
- Testosterone (Total)
Measures total circulating testosterone and helps identify low or high testosterone patterns relevant to symptoms and hormone health.
- Sex Hormone Binding Globulin (SHBG)
Helps determine how much testosterone is bound and unavailable, improving interpretation of symptoms when total testosterone alone is unclear.
- Albumin
Supports calculation of free testosterone by accounting for loosely bound testosterone that contributes to biologically available hormone.
- Free Testosterone (Calculated)
Represents the biologically active portion of testosterone, offering a more accurate reflection of testosterone activity when binding proteins affect total levels.
- Testosterone (Total)

How accurate are home finger-prick tests compared to clinic tests?
Our home finger-prick tests use the same accredited laboratories as our clinic tests. While clinic tests allow for more comprehensive panels, home tests are highly accurate for the parameters they measure.
Do I need a GP referral for a blood test?
No, you don’t need a GP referral. You can book directly with us for any blood test. We are a private clinic offering direct access to comprehensive blood testing.
How old do I have to be to have a blood test?
We will only draw blood from those aged 16 and above due to legal requirements.
How long does it take for the blood test results to come?
If you have used our clinic to complete a blood test, we send off all samples the same day to the lab to be processed. If you have used a home test kit, then once your sample has been sent off the lab will analyse your sample. Results are usually received within 72 hours.
How do I perform the home finger-prick test?
Your home blood test kit will contain easy-to-follow instructions on how to take your own finger blood sample. If you have any concerns or questions prior to using the kit, please contact our phlebotomists who will be happy to assist.
How do I prepare for a blood test?
There is no preparation required prior to taking any of the blood tests. Please simply remember to stay hydrated prior to your appointment. This is to help your veins dilate better to enable a quick and efficient blood sample to be taken and reduce the risks of feeling faint following your blood test.
Please inform the phlebotomist before your test if you are currently taking any blood thinning medication.
Should I fast before my blood test?
Fasting is not required for most blood tests. However, if your profile includes cholesterol tests and you’ve previously had high levels, consider fasting for 8 hours beforehand. While not essential, fasting can provide more accurate results.
Note: Fasting means abstaining from any food and drink, except for water.
