Order home testosterone tests online
Prices from £49.99
Testosterone is a steroid hormone that is produced by the male testes (testicles). If you’re worried that your testosterone levels may be low, you can do a simple blood test at home using our home total testosterone test kit. If your testosterone level is low or borderline a repeat test after at least 4 weeks is recommended to confirm the result and you would need to see your GP or a specialist if you wanted to start testosterone replacement therapy (TRT). To order and use the test kit, follow these 5 easy steps:
Using a home test works in the following steps:
- Place an order and get your kit delivered to your door, or collect from a local post office (delivery is free)
- Collect a few drops of blood using a finger-prick test
- Send your samples to our UK-based, accredited partner laboratory (postage is free)
- Once your results are available (in 2 to 3 days), our doctors will review your results
- One of our doctors will contact you, via a secure and confidential message in your patient account, to let you know your results and give you advice and support on what to do next
In some cases, the doctor may need to ask for more information. They may contact you by phone, so make sure your telephone number is up to date in your online account.

About home testosterone testing
How to order a testosterone test kit online in the UK
The process is quick and easy – just follow these simple steps:
- Fill out a short online assessment
- Place an order
- Your order will be then posted to your preferred address or you can collect it from a local post office instead
How to use the test kit
- Follow the instructions included in your test kit
- Take the sample between 7am and 11am
- Do not eat or drink anything except water from midnight the night before (talk to your doctor first if you have been told you should not fast or take medications that need to be taken with food or for diabetes)
- Don’t take the sample if you’re feeling unwell
- Wash your hands before use
- Dry your hands and use the alcotip swab to clean the fingertip you would like to collect the sample from (the third or fourth finger of your non-dominant hand is usually best – the one you don’t write with)
- Twist and remove the purple stick from one lancet
- Place the lancet on your fingertip and press the purple button at the end
- If it doesn’t work the first time, you can use one of the two remaining lances to try again
- Once it has worked, you should notice a small drop of blood forming on your fingertip
- Use a clean tissue to wipe the first drop away
- Hold your hand downwards and massage the side of your finger to form another drop of blood
- Use your other hand to gently squeeze the finger you are using and catch drops in the collection tube
- You should fill the small tube to the upper line
- If you are unable to fill the tube to the line, please use an additional lancet on another finger to complete the sample
- Once you have collected the sample, use the plaster provided to stop the bleeding
- Screw the lid on the collection tube, turning it several times until it is closed securely
- Please make sure you fill out your details on the sticky label and affix it on the tube
- You then need to put your sample tube inside the protective wallet and place the wallet inside the prepaid envelope, along with your used lancets
- You can use any UK post box to send your test kit to the lab
How the results work
- Your results will be sent to your ZAVA account
- They should be ready within 2-3 days of the laboratory receiving your sample
- They will include the level of total testosterone measured in your blood sample
- You results will include advice from a ZAVA doctor on your next steps
The testosterone kit is a home pin-prick blood test kit used to check the level of total testosterone in the blood. The test will tell you if your testosterone levels are within the normal range or not.
In men, testosterone is responsible for:
- The growth of body hair
- The growth of the penis during puberty
- Deepening of the voice during puberty
- Muscle development
- Sex drive
- Sexual function
Testosterone levels can fluctuate throughout the day even in healthy males. So, it’s important that the test is carried out at the correct time of day. For example, testosterone levels are usually at their highest in the morning and at their lowest in the late afternoon or evening.
Testosterone levels decline with age, too. In men, it can fall at a rate of 1-2% each year from the age of 40.
You may want to consider getting a testosterone test if you are experiencing any of the following symptoms:
- Low sex drive
- Changes to sexual performance e.g. erectile dysfunction
- Reduced motivation
- Low energy levels
- Reduced muscle mass
- Increased fat levels
- Reduced bone density
You may want to consider a testosterone kit if you’re experiencing erectile dysfunction (ED). ED is also known as ‘impotence’ and is defined as not being able to get or keep an erection. ED is a relatively common condition which affects 50% of men aged between 40 and 70. But, low testosterone is rare, even in men with ED: 4% for men under 50 and 9% for men over 50.
Testosterone replacement therapy (TRT) is only recommended if the test reveals that you’re deficient in the hormone (your total testosterone level is less than 8 nmol/L or in some cases if you have a borderline level of 8-12 nmol/L). These ranges may vary slightly depending on the laboratory that processes your result.
If your results indicate you have a deficient or borderline total testosterone level, then you’ll need to visit your doctor for further tests to find the cause. You will need to talk to your GP or specialist before starting TRT as this will depend on your symptoms and whether you plan to have children in the future. Once you’ve been using your TRT for at least 12 months and you’re having regular check ups with your doctor, you’ll be able to reorder from us.
Testosterone is given to men who are deficient, and it can have benefits such as:
- Increased bone strength
- Increased sexual function
- Improved sex drive
- Increased muscle strength
As well as TRT, you may find making some lifestyle changes may help to relieve your symptoms. For example, ED or a low sex drive can be caused by:
So, changes to your lifestyle can help, for example:
- Increasing physical exercise
- Improving your diet
- Quitting smoking
- Reducing alcohol intake
Although testosterone can be linked to fertility, the testosterone test we provide can’t be used to test for fertility.
Male fertility tests look at semen and the quality of a male’s sperm. The test can be carried out at home or in a clinic. The sample is sent away to a lab where scientists analyse it. They will check sperm for:
- Motility (how well they move about)
All of these can affect the quality of sperm and the individual’s fertility. Home test kits consider a low sperm count as anything under 20 million sperm per millilitre, but recent international guidelines state a sperm count above 15 million sperm per millilitre as normal.
Several factors can affect male fertility:
- A hormone imbalance
- Infections, like gonorrhoea or chlamydia
- Enlarged veins in the testicles
- Genetic problems, like Klinefelter syndrome
- Excessive alcohol consumption
If you’re worried about your fertility, you should speak to your GP who can arrange a semen analysis or talk you through other options like lifestyle changes, if appropriate.
