What is a Kidney Function Test at home?

The kidneys are two small secondary organs that produce urine. These are responsible for filtering toxins from the blood and achieving a balance of water, ions and pH.

5 BioMarkers:

  • Urea: gauges how well they are functioning.
  • Creatinine: determines malfunction or failure, level of creatinine. Blood serum creatinine.
  • Phosphate: Is essential for producing energy, muscles, nerve function and bone growth. Measures the amount of phosphate.
  • Albumin: measures the amount of protein in the transparent liquid portion of the blood.
  • Bicarbonate: healthy organs help keep your bicarbonate levels in balance. Measures the amount of bicarbonate in your blood.

Please take the sample in the morning before eating or drinking.
