Special instructions

Fasting is optional for this test. Eating fatty foods might affect the results of a small number of blood tests so we may advise a retest when you are fasted. If you are interested in your triglyceride, LDL or omega 3 levels, then we do recommend fasting. Avoid heavy exercise and eating meat-rich meals for 48 hours before your test.

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. They control the concentration of ions and electrolytes in the blood and also play an important role in producing erythropoietin, a hormone which stimulates red blood cell production. 

Chronic kidney disease can progress over many years with few signs or symptoms that can be specifically related to kidney function, especially in its early stages. Symptoms that can indicate kidney disease include swollen feet and ankles, high blood pressure and changes in how frequently you urinate. Some groups of people are at higher risk of developing kidney disease; they include people of African descent, smokers, the obese, the elderly and people with diabetes. 

This check includes wider tests for general health such as liver function, cholesterol and iron status.

Please not that this test is designed to be sent in the post and therefore excludes some biomarkers which are 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 sodium and potassium.
