Kidney Function Test: Symptoms, Types, and Treatment

 The kidney performs vital functions in the human body, such as filtering out toxins and maintaining the level of acid-base. This test is recommended by a medical professional if the person has symptoms that point toward a problem in kidney function. People with pre-existing medical conditions such as diabetes or high blood pressure are also asked to undergo this test.

Symptoms of Kidney Problem

  • Tiredness

  • Nausea

  • Frequent urination or changes in color

  • Swollen face, hands, or other body parts

  • Fatigue


Common Test for Kidney Function


A KFT lab test is conducted on a person to find out if there are any issues with kidney function. This can be done through a simple blood or urine test. KFT tests are used to check the filtration rate of the kidney. These are some of the most common KFT tests recommended by the doctor:

Estimated GFR Test


This test is used to check the ability of the kidney to filter out toxins from the body.

Blood Urea Nitrogen Test


A blood urea nitrogen test is used to figure out the nitrogen level in the blood. Fluctuations in the urea level in the body indicate a problem in the filtration capability of the kidney.

Imaging Test


An imaging test is usually suggested by the doctor to check for any changes in the physical appearance of the kidney. Some of the common imaging tests available in medical treatment are ultrasound, biopsies, and tomography.

Serum creatinine 


This test is performed to determine the creatinine level in the body. If its level is higher than normal, then it indicates a problem in kidney function.

Urinalysis


This is a test that uses urine samples to find out kidney-related diseases such as kidney stones, diabetes, and other underlying medical conditions.

The price of KFT tests is not very high. So, anyone can afford it if their doctor suggests they undergo these tests. Many renowned medical laboratories conduct these tests at affordable rates. These test reports are used by the doctor to recommend the course of treatment in the case of any irregular results.
