More than 10% of the UK population are living with kidney disease
Our kidney blood test will show you a detailed breakdown of your results for each of the biomarkers tested. It will tell you if your results are within the normal range for your age for each biomarker tested. You’ll also receive comments from our team of doctors on any out of range results. It’ll help you understand how well your kidneys are functioning and if you’re at risk of developing kidney disease.
Our kidney function blood test is a finger prick test, making it easy to collect your blood sample from home. It comes with everything you need to do the test, including free return postage to our labs for analysis. We’ve put together a full how-to video to help you collect your blood sample.
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:
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.
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.
