Ft
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.

Sh
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.

Al
Another protein produced in the liver which binds to testosterone, inhibiting its ability to be used by the body’s cells.
Os
Although oestrogen is considered to be a predominantly female hormone, it’s also present in men and plays an important role in regulating their libidos, erectile function, and the production of sperm.
A delicate balance of oestrogen and testosterone ensures optimal sexual function, as well as joint and brain health.

Liver and kidney function is reviewed before starting TRT to ensure that there are no other conditions present.

The full blood count shows general health markers and indicates if your red blood cell count is too high.
Testosterone can increase the number of red blood cells the body produces, so monitoring this while you’re on TRT is important.

Ferritin is an indicator of a condition that may cause low testosterone.

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.
