Kidney Function Test

What is a Kidney Function Test?

This test will provide essential information on kidney function, principally in excretion and homeostasis, which is the desired healthy steady state that signals good health and wellness. Electrolytes are salts and minerals which help to regulate and control the balance of fluids in the body. These minerals play a role in muscle contraction, regulating blood pressure and ensure your system is functioning properly.

Why consider a Kidney Function Test?

You may wish to consider our kidney function test if you are concerned about your kidney health or have been experiencing any of the following symptoms:

  • Irregular heartbeat
  • Fast heart rate
  • Fatigue
  • Lethargy
  • Convulsions or seizures
  • Nausea
  • Vomiting
  • Diarrhoea or constipation

How does this test work?

Once you have taken your blood sample, place it in the postage-paid envelope provided and send it to our accredited UK laboratory for analysis.

What tests will you run on my sample?

Our kidney function test will review the following key elements in your body:

  • Urea. A waste product from your metabolism that is normally removed by your kidneys. Excess levels can indicate a problem with your kidney function.
  • Creatinine. This is another breakdown product of muscle metabolism and an excellent indicator of kidney function and health.
