What is Renal Function Test (RFT)

An RFT test or Renal Function Test refers to a group of tests done to know about your kidney health. They include various tests such as electrolytes, minerals, proteins, and glucose in your blood. These tests help healthcare providers determine kidney health and assess how well they work.

When your kidneys do not work well, the toxins and waste products accumulate in your body because the kidneys do not excrete them. The fluids can also not leave your body, which leads to a potentially life-threatening condition. Various risk factors can put you at risk of developing kidney disease. However, the most common risk factors are diabetes and hypertension. Therefore if you have even one of them, you might need to undergo renal function tests often. It is because your healthcare providers would check whether your kidneys are healthy or not. If you are at risk of developing kidney disease, get renal function tests done frequently.

What Is Renal Function?

Your body has a pair of kidneys that work day and night without any break to filter your blood. The kidneys keep the nutrients, minerals, and electrolytes that your body needs and dispose of the remains. It protects your body from toxin accumulation by excreting unwanted substances in a timely manner. Moreover, over your kidneys are the adrenal glands that regulate hormones that regulate blood pressure. They can sense if your blood pressure is too high or too low. And they secrete the hormones accordingly to normalize your blood pressure. Your kidneys also help in red blood cell production by secreting erythropoietin.

To stay healthy, your kidneys must work well. If they stop working, you will need to get a transplant or undergo frequent dialysis sessions.
