Our at-home Free Testosterone blood test kit is specially designed for men who want to monitor their testosterone levels. This comprehensive test measures not only total testosterone levels but also albumin, sex hormone-binding globulin (SHBG) and free testosterone levels, providing a more complete picture of your hormone health than just checking total testosterone.

- A blood sample collection kit, which will be delivered within 2-3 working days

Blood sample collection options
Finger prick kit (FREE)
All our kits require a finger prick blood sample which is quick and easy to do at home. But if you don't like the idea of squeezing blood out of your finger, here are some other options:
A home visit by a nurse (+£60)
Have a nurse visit you at home to take your blood sample from your vein. The kit will come with everything the nurse needs to do the blood sample collection. Once you've placed your order, we'll be in touch to arrange an appointment.
Visit a clinic (+£45)
You can visit one of our partner clinics to have a nurse take a blood sample from your vein. Select this option at checkout where you can also see which clinics are near you. Once you've placed your order, we'll send you an email to arrange your appointment.
Organise a nurse myself (FREE)
If none of the above options work for you, you can arrange your own medical professional to collect your sample. There is no additional charge for this. Once you've ordered your test, we'll send you everything you and your chosen medical professional will need to collect a sample and post it back to our labs.
You can choose your blood sample collection method in the checkout. Learn more about sample collection.
When to take the test
We recommend you collect your blood sample within 3 hours of waking up and before any strenuous exercise.
What is Free Testosterone?
Free testosterone is the unbound form of testosterone, the primary male sex hormone, that circulates freely in the blood. Unlike total testosterone, which includes both bound and unbound testosterone, free testosterone is the biologically active form that can directly interact with cells and tissues throughout the body.
In the context of sports performance, free testosterone plays a crucial role in muscle growth, strength, and endurance. It stimulates protein synthesis, enabling muscle growth and repair, while also contributing to red blood cell production, enhancing oxygen delivery to muscles during intense exercise. Adequate free testosterone levels are essential for athletes to optimise their performance, particularly in endurance and strength training activities.

Customer service has been fantastic
Prompt, timely and very satisfactory. I had an issue, I gave feedback. They responded directly to the feedback. We both learned something and I am happy to be a client once more. Well done Edge, I just wish more companies looked after their clients like these guys.

Great service!!
Used this service a couple of times now, and they’ve always done exactly what they’ve said! I’ve received my results perfectly. One of my tubes clotted before the lab received it one time, but forth edge sent another free of charge and the second attempt was successful! Some of the bad reviews here are all human error, always check your emails because forth do a great at keeping in contact and they always respond to my emails very quickly.
