Kidney Function Test
The kidneys play a vital role in determining your overall health. They act as a filter for your blood, retaining the products which your body needs and filtering out the waste products as urine. Besides reabsorption of glucose, amino acids, and glucose, the kidneys also take part in hormone production which in turn regulate your blood pressure, bone health, and production of red blood cells.
The purpose of kidney function test is to examine the optimal health of your kidneys, and check if they are functioning well. This test is done to monitor your urea and creatinine levels, along with essential salts like sodium and potassium and your filtration rate. This helps the doctor evaluate any kind of kidney diseases, infections, stones, or even cancers.
