Kidney Function Test: Types and Prices

Kidneys are extremely vital for the proper functioning of the human body. They are responsible for a diverse set of functions, such as maintaining the hormonal levels in the body, removing toxins, maintaining blood pressure, production of red blood cells, and so on. 

Hence, it is obvious that the hindrance in the functioning of this organ will lead to several problems for the body. A kidney function test allows medical professionals to take a close look at their patient’s kidneys to look for any abnormalities.

In this article, we will be taking a look at the different kinds of function tests for this organ. We will also be checking out the kidney function test price

Types of Kidney function Tests

A kidney function test includes several tests that allow doctors to check the glomerular filtration rate of their patient’s body. The tests include:

1. Serum creatinine test

Creatine is an amino acid that is normally found in the muscles of the human body. It produces a waste product called creatinine. Kidneys are responsible to get rid of this creatinine from the body. Hence, a high buildup of creatinine in the body indicates that the kidney is malfunctioning. 

There are several signs that one needs to get a serum creatinine test done. These include high blood pressure, swelling of body parts, and changes in the urinary routine of a person. Fatigue and lost appetite can also imply faulty kidneys. 

The normal levels of creatinine levels in the adult human body are as follows:

  • In men: 0.9 to 1.3 mg/dL
  • In women: 0.6 to 1.1 mg/dL

2. BUN test

BUN test stands for the Blood Urea Nitrogen test. Urea nitrogen is the waste product created when the liver is broken down in the liver of the human body. Urea nitrogen is a toxin and is eliminated from the body from time to time through urination by the facilitation of the kidneys. 

Similar to creatinine, the amount of urea nitrogen present in the blood allows medical professionals to understand whether or not the kidneys are functioning as well as they are supposed to. The BUN test is often carried out with the serum creatinine test.

Conditions like heart failure, liver damage, and malnutrition can be diagnosed through this test. The normal levels of urea nitrogen in the blood are as follows:

  • In men: 8 to 24 mg/dL
  • In women: 6 to 21 mg/dL
  • In children: 7 to 20 mg/dL

3. Urinalysis

As the name suggests, urinalysis refers to the analysis of the patient’s urine. Since urine is the eliminated toxin from the body, its assessment can help diagnose a variety of medical conditions. 

Along with ensuring the proper functioning of kidneys, urinalysis also allows doctors to diagnose diabetes, liver diseases, and so on. Signs that you need a urinalysis done include painful urination, pain in the back and abdomen, and bloody urine in some cases. 

Urinalysis is also carried out before the patient is sent for surgery or checked for urinary tract infections. The urine is analyzed visually and medically by trained professionals to check for any abnormalities in its composition. Since kidneys are responsible to filter out urine, its status can be checked through a urine sample. 

4. Estimated glomerular filtration rate test

Glomerulus is responsible for filtering out the waste from the blood to form urine. It is a proper network of blood vessels, and if it malfunctions in any case then urine can be quite painful or in some cases – bloody. The proper or improper functioning of the glomerulus directly implies the health of a patient’s kidney as well. 

Hence, people who exhibit the symptoms of kidney disease are asked to get a Glomerular Filtration Rate (GFR) test done. These signs include abnormal swelling, foamy urine, backache, and so on. 

People suffering from conditions like hypertension, heart disease, diabetes, and so on should also consider getting tested. The GFR level of 90 ml/min indicates healthy and functioning kidneys in an adult human body.

5. Cost of kidney function test

Since the KFT includes several tests, the package pricing may vary according to your needs. However, overall the kidney function test price falls within the range of 130 rs to 500 rs. 

The kidney function test price depends upon the city you live in and the clinic you choose to get tested from. The average cost, either way, should be around 200 to 250 rs. 


A kidney function test lets the doctor assess the functioning of one of the most vital sets of organs of the human body. It is strongly suggested that you get tested as soon as you exhibit any symptoms of a kidney malfunction. The kidney function test price is quite affordable too. Hopefully, this article will provide you with everything that you need to know about the different types of KFT and the kidney function test price.
