From the expert

The kidneys are two small organs located on either side of the body. They are responsible for filtering waste products from the blood and removing excess bodily fluid in the form of urine, controlling the concentration of ions and electrolytes in the blood, and aiding in red blood cell production.

Our Kidney Blood Test measures creatinine, urea and eGFR to indicate how well the kidneys are functioning. Chronic kidney disease (CKD) can progress over many years with few signs or symptoms, especially in its early stages. Some groups of people are at higher risk of developing kidney disease; they include people of African descent, smokers, the obese, the elderly, people with diabetes, high blood pressure and high cholesterol.

Please note that this test is designed to be sent in the post and so excludes potassium which is not stable in the post. If you have been advised to get a kidney function test by your doctor then please use our Urea and Electrolytes Blood Test which includes potassium.
