A Renal Profile or Kidney Function Test (RFT/KFT) is a group of diagnostic assessments that are used to determine the health of the kidneys by evaluating various parameters such as proteins, electrolytes, and minerals. Kidneys not only flush out waste and toxins from our body through urine but also aid in the production of vitamin D, red blood cells and blood pressure-regulating hormones. Therefore, keeping your kidneys healthy should be a primary aim and this is where a Kft test comes in handy.
