Advanced Kidney Function Blood Test

49.00

A quick and easy finger prick blood test to give you insight into how your kidneys are functioning. Our kidneys play a number of key roles in ensuring we are healthy.

  • One of the key functions of the kidneys is to filter blood and remove waste and excess fluid through urine production.
  • Kidney disease rarely shows any signs or symptoms until your kidneys are very badly damaged, therefore, getting a test is recommended.
  • If you currently have chronic health conditions such as diabetes, high blood pressure or a family history of kidney disease it is highly recommended to have a kidney function test
  • Results within 2-5 days once sample kit has arrived at the lab
  • This test kit includes free shipping

Learn about the Biomarkers in this test

Biomarker profiles

  • Kidney
Creatinine
Creatinine is a chemical waste molecule that is generated from normal muscle break down. Sportspeople can therefore have higher levels than the average person. Creatinine is cleared from the kidneys and so is also an accurate marker of kidney function, and may help in diagnosing kidney disease.
Urea
Urea is a waste product produced by the body when it breaks down proteins in the liver. Once the urea is made, it is transported to the kidneys, which filter it out of the blood and remove it from the body in the form of urine. Measuring the levels of urea in the blood can therefore reflect how well both the liver and the kidneys, are functioning. It is important to note that even if one kidney is severely damaged but the other is functioning perfectly, results may still return as normal.
eGFR
The estimated glomerular filtration rate (eGFR) assesses how well the kidneys are working by estimating the amount of blood filtered through the kidneys. The glomeruli are tiny filters in the kidneys responsible for removing waste products. If these filters do not do their job properly, kidney function can be impaired. The eGFR calculation is an estimate of actual glomerular filtration rate, calculated using your age, gender, ethnicity, and serum creatinine levels.
Sodium
Sodium is both an electrolyte and a mineral. It helps to regulate the water and electrolyte balance of the body, and is therefore an important factor in blood pressure and pH. It also plays an important role in the function of nerves and muscles. Sodium levels in the blood are regulated by the kidneys.
