Additional biomarkers can be added by personalising this test.
Biomarkers are specific compounds we can detect in your blood sample that reflect different things about your health. Your test will tell you your levels for each of the above biomarkers, and whether they are in a normal range.
When you purchase this test subscription plan, we will automatically send you another test kit in a few months. Don't worry - you have full control over when this will be, and you can change/cancel it anytime.
When you first purchase this test, you can choose your subscription options in the checkout. We do this, because we recommend taking multiple tests over time to track how your biomarkers change. You'll be charged per test kit (rather than monthly, for example).
One test will show you what areas you need to focus on, continued testing will help you learn how your training, diet and lifestyle is impacting your health.
We recommend a follow up test 3 months after your first test, followed by a test every 6 months depending on your results, but its up to you!
Yes, you can tailor/customise subsequent tests (via your app) to focus on just the areas that need improving.

WHEN TO TAKE THE TEST?
Testosterone levels are at their peak first thing in the morning, so it's best to collect a sample for the testosterone test between 8am - 10am.
You can check your testosterone levels at home using our finger-prick blood test kit.
We also offer phlebotomy services, where a healthcare professional draws blood from your vein either at your home or one of our partner clinics.
Our doctors will review your results and provide a comment to help you better understand your levels and what you can do to improve (you can opt out of this during checkout if you’d prefer).
Learn more about how Forth blood tests work here.
Make sure you’re well hydrated and warn before collecting your blood sample. Running your hands under warm water can help increase blood flow and make the process easier. We recommend collecting your sample between 8 am and 10am, when your testosterone levels are naturally at their highest.
Getting the insights you need to improve your health has never been easier.
It takes 5 minutes to collect a small sample of blood from your finger tip. Post it back to our labs using the Tracked-24 envelope included in your kit.
You will receive your Results within 2 working days in the Forth app, along with the optional doctors comment and detailed report.
The detailed report makes it easy to identify areas that need improving, make changes and track your progress.
"Testosterone is an hormone for both men and women. It can help identify conditions like low testosterone, polycystic ovary syndrome (PCOS), or androgen excess. This test is best used in conjunction with a wider hormone or health panel to assess how this powerful hormone is impacting your wider health."

What causes low testosterone?
Low testosterone can happen naturally, as levels start to slowly decline in men from their early 30s. But, other factors can cause testosterone levels to drop, such as overtraining, stress, medication and lifestyle choices such as lack of exercise, poor diet, and alcohol consumption.
Low testosterone, also known as hypogonadism, comes with various symptoms, including:
What causes high testosterone?
In men, high testosterone levels can be caused by testosterone replacement therapy (TRT) or a number of health conditions including: androgen resistance, congenital adrenal hyperplasia, and testicular cancer.
In women, high levels of testosterone can result in irregular or absent periods, frontal balding, acne, more than average body hair, increased muscle mass, and a deeper voice. This can be caused by a number of health conditions including polycystic ovary syndrome (PCOS).
We advise consulting with your GP if your results are high so this can be investigated further.
Does exercise increase testosterone levels?
Exercise can significantly impact testosterone levels in both men and women. In men, regular exercise, especially resistance training, can lead to a temporary increase in testosterone levels. This is due to the release of hormones that stimulate testosterone production, such as growth hormone and insulin-like growth factor 1 (IGF-1).
However, the effects of exercise on testosterone levels are more complex in women. While regular exercise can also lead to a temporary increase in testosterone levels, these increases tend to be smaller and less sustained than in men. This is because women’s bodies produce lower levels of testosterone naturally and are less responsive to the hormonal signals that stimulate testosterone production.
The type of exercise also plays a role in how testosterone levels are affected. Resistance training, which involves lifting weights or using resistance bands, is generally more effective at increasing testosterone levels than cardio exercise. This is because resistance training causes muscle damage that the body repairs, leading to an increase in the production of testosterone and other hormones that promote muscle growth.
Whilst exercise can have a positive effect on your testosterone levels, repeat overtraining and not enough recovery time can cause testosterone levels to drop and cortisol levels (the “stress hormone”) to rise. It’s important to ensure that you schedule adequate recovery into your training plan to give your body a chance to both absorb your training and replenish your biomarkers.
Can I increase my testosterone levels naturally?
If your testosterone levels are low and you want to increase them without TRT, you can.
Here are some natural ways to increase testosterone levels:
Remember that these are just general guidelines, and what works for one person may not work for another. It is always a good idea to talk to your doctor to get personalised advice on how to maintain healthy testosterone levels.
Can I use this test when on TRT?
Testosterone replacement therapy (TRT) will cause you to have synthetic hormone levels. The Testosterone test will be able to show the levels of this hormone in your body, but it is worth remembering that this will not show you how your body is performing at producing testosterone. High doses of TRT can cause your levels to go above the detectable levels of the analysis technology.
Is this test suitable for women?
Yes, This test is suitable for both men and women.
Whilst testosterone is usually identified as a “male hormone”, premenopausal women produce both oestrogen and testosterone. You can learn more about the role testosterone plays in the female body in our blog.

Learn more about your data security.
Can I have someone take my blood for me?
Yes. We offer two options if you do not want to do our finger prick test. The first is a home appointment where a nurse comes to your home to take a blood sample. The second is to visit a Phlebotomy clinic near you that offers a blood sample service.
A blood sample will be taken from your vein and we will provide you with everything you need to give to the nurse to allow them to take the sample.
The nurse will give you the blood sample to return to us using the pre-paid envelope provided.
Does a doctor review my results?
We have a team of doctors and nurses who look at all results and will comment on any results that are outside of the normal range for your age.
