What is a urea test?
A urea test is a straightforward blood test that provides valuable information about how well your kidneys are functioning. It measures the level of urea, a waste product produced when your body breaks down proteins in your bloodstream. Normally, the kidneys filter urea out of the blood so it can be removed through urine. If your kidneys aren’t working properly, this waste can build up, sometimes without noticeable symptoms.
Urea levels can be influenced by several factors, including hydration, diet and medication. That’s why the test is often used as part of a wider blood panel to investigate issues such as tiredness, swelling or concerns around kidney health. It is also commonly requested for people managing chronic conditions or undergoing treatment that may affect the kidneys.


How is a urea test performed?
A small blood sample is taken, usually from a vein in your arm. The process takes only a few minutes and involves minimal discomfort. In some cases, you may be asked to fast beforehand, especially if the urea test is part of a broader blood test panel.
Once the sample is collected, it is analysed in our accredited laboratories. Results are typically available within 24 to 48 hours and are explained clearly by our clinical team, ensuring you understand what the results mean for your health.
What does a high urea level indicate?
A raised urea level can indicate several possibilities. These may include:
- Reduced kidney function
- Dehydration
- A high-protein diet
- Certain medications
- Increased protein breakdown due to illness or injury
A single result is rarely diagnostic on its own. Our team will consider your urea levels alongside your symptoms, medical history and any other test results to provide a clear and informed picture.
Is a urea test the same as a blood urea nitrogen (BUN) test?
Yes. In the UK, we refer to it as a urea test, while in some other countries, particularly the United States, it is called a blood urea nitrogen (BUN) test. Both measure the same compound and offer the same insights into kidney health.
What does a urea test show about kidney function?
The kidneys filter waste products like urea from your blood. A urea test helps assess how effectively this process is working. High levels may suggest the kidneys are not clearing waste as efficiently as they should, particularly when interpreted alongside tests such as creatinine and eGFR (estimated glomerular filtration rate).
If there are any concerns about your kidney function, our consultants will guide you through further investigations or treatment options.
