What is a Kidney Function Test?

The Better2Know Kidney Function test gives you access to crucial information regarding kidney function, primarily excretion and homeostasis, which is the optimal state which indicates good health and wellness. This test looks at the salts and minerals, or electrolytes, aid in the control and regulation of fluids in the body. They also play a part in regulating blood pressure, muscle contraction and assurance that your body is functioning the way it should.

  • Vomiting
  • Irregular heartbeat
  • Lethargy
  • Fatigue
  • Diarrhoea or constipation

How does this test work?

This test is run on a small blood sample taken in the comfort of your home. You will also be provided with alco-wipes, a plaster, three finger prick lancets and a postage paid return envelope to return your completed sample to our lab.

What tests will you run on my sample?
