How does a subscription work?
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).
Why subscribe to multiple tests?
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.
How often should I test?
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!
Can I change what's tested in future tests?
Yes, you can tailor/customise subsequent tests (via your app) to focus on just the areas that need improving.

Frequently asked questions
This is what our customers ask us most about this test. For more information, try our help centre.
What damages the kidneys?
There are many causes of kidney disease. The most common causes in the general population are high blood pressure and type 2 diabetes. Other issues include some long term medications, such as non-steroidal anti-inflammatory drugs like Ibuprofen, and some auto-immune conditions.
How can I improve my kidney function?
It’s really difficult to reverse kidney damage once it has occurred. However, ways to protect yourself from developing kidney damage is to keep well hydrated, regular exercise (to help avoid high blood pressure), stopping smoking, and keeping cholesterol at a healthy level.
What is the first sign of kidney problems?
Kidney disease is often a ‘silent’ problem. Many people don’t know they have a kidney problem until it becomes very severe. This is why it’s worthwhile checking how they’re working, such as with a blood test to check kidney function.
What are kidney stones and how do I prevent them?
Kidney stones are relatively common with an estimated 1 in 10 people experiencing this very painful problem in their lifetime. Kidney stones can develop in 1 or both kidneys and most often affect people aged 30 to 60 years old. Sometimes they can also lead to bladder or kidney infections.
Big stones can cause symptoms, including:
- Pain – mostly in the side or your lower back
- Pain that comes in waves, building to a crescendo then reducing for a period
- Feeling nauseated or vomiting
How soon will the test arrive?
If you order your test before midday on a Monday to Friday then your kit will be dispatched
the same day.
All our kits are sent out via Royal Mail first class post, so it should be with you within 1-2
working days.
How secure is my data?
We have strict processes in place to ensure the protection of your data. Following GDPR the company also operates under tight legal rules about the sharing of data which ensures that data is only shared if it is crucial to the delivery of our service. For example, our doctors see customer results at the time of review, however, after review, access to results is withdrawn.
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.
Can I download the results to share with my GP?
Yes, you can download your results from your health dashboard as a PDF to share with your GP.

Kidney Function Blood Test, recommended by our doctors
"A renal function test assesses how well your kidneys are working. It typically involves measuring creatinine and blood urea nitrogen levels in your blood. These values help determine if your kidneys are effectively filtering waste and regulating the balance of fluids and electrolytes in your body. Abnormal results may indicate kidney problems."
Dr Thom Phillips
