Kidney Function Test Overview

Renal function tests (RFT) are done on urine and patient blood to establish how well the kidneys are working. They aid in the diagnosis and management of conditions affecting kidneys. They can be used for general health screening and screening of those patients who are at risk of developing a kidney disease i.e., as high blood pressure (hypertension), diabetes, cardiovascular disease, obesity, elevated cholesterol, or a family history of kidney disease. Adjusting dosages of drugs excreted by kidneys.

What are the different names for renal function tests?

This test is known by two names:

  • Kidney function test
  • Renal function test
  • Urine Routine
  • Creatinine
  • Uric Acid

The kidneys' primary function is to filter out the waste materials from our bodies in urine. A kidney function test is used to determine how well the kidneys are performing their function with the help of a blood test and urine test.

A kidney function test is recommended in the following cases:

  • Patients show symptoms of acute renal failure, such as decreased urine output, swelling in feet and ankles, shortness of breath, fatigue, and confusion.
  • Patients show symptoms suggestive of chronic kidney diseases, such as swelling in feet and ankles, weight loss, shortness of breath, blood in urine, and increased urination at night. 
  • Renal function tests may also be ordered as a routine health screening test.
