What this test measures
4 biomarkers Analysed
Total Testosterone
This is the total amount of testosterone found in the blood. Some of it is attached to proteins, such as Sex-Hormone Binding Globulin (SHBG) or Albumin, which transport it around your body.
Free Testosterone
Free testosterone is the testosterone that is unbound and available to be used by the body’s cells. When a cell binds to free testosterone its functionality is enabled. The more you have of it, the better.
Sex-Hormone Binding Globulin (SHBG)
This protein is produced in the liver and regulates hormone levels by binding to sex hormones, including testosterone. When your SHBG levels are high, your body has less free testosterone available to be used by the body’s cells.
Another protein produced in the liver which binds to testosterone, inhibiting its ability to be used by the body’s cells.

What is Testosterone Deficiency (TD)??
Low testosterone is a common condition that men can be born with or develop due to age, stress, disease, physical trauma, an unhealthy lifestyle or environmental factors.
What are the key symptoms of TD?
Men with low testosterone often report low mood, irritability, fatigue, anxiety, reduced libido or difficulty achieving an erection. Other common symptoms include brain fog, lack of motivation, low confidence, difficulty losing weight and difficulty gaining muscle.
How do you test for TD?
Blood testing is the only way to know for sure if you have a testosterone deficiency. Our Initial Testosterone Blood Test (a simple finger-prick test) can be taken at home. If the results show that you have low testosterone and you’d like to start testosterone replacement therapy, UK regulations require you to take a second, more comprehensive blood test first to ensure that you can safely start treatment. This one is a venous test which has to be administered by a nurse or phlebotomist.
How common is TD?
Research has confirmed that testosterone counts in men are significantly lower than they were just a few decades ago. One in four men over the age of 30 may have abnormally low testosterone levels according to scientific studies.*

Around the age of 30 testosterone levels naturally begin to decline, but it’s usually a very gradual process. For most men, testosterone levels drop between one to two percent each year from the age of 35. Free testosterone levels also drop considerably as men age, making TD even more common. An increase in obesity, hormone-disrupting environmental chemicals, and anabolic steroid use is also making testosterone deficiency in younger men more prevalent than ever.

Will I be able to talk to a licensed doctor?
Yes, you’ll have a consultation with one of our doctors to discuss your test results and they can provide a personalised treatment plan tailored to your needs. Our doctors specialise in TRT for men and are all registered with the General Medical Council.
How do these blood tests lead to treatment?
Our initial blood test will establish whether you have a testosterone deficiency. If the first test shows that you have low testosterone you’ll need to take our second, more comprehensive blood test if you’d like to start TRT - this is due to UK regulations. If both tests show that you have low T levels, you’ll discuss suitable treatment options with one of our doctors and during an in-depth consultation before starting treatment.
How soon will the test arrive?
Our blood test kits usually arrive within three working days. It may take longer over public holidays.
When will I get my results?
We’ll get in touch to give you your results within two to three business days. One of our TRT specialists will then walk you through the results, provide advice, and answer all of your questions.
