About kidney function test

Why is KFT done?
  • To check for renal disease, also known as kidney failure and end-stage kidney disease.
  • To identify the type of renal disease.
  • To assess glomerular filtration rate (GFR).
What does KFT measure?

A kidney function test measures the following:

  • Blood Urea Nitrogen (BUN): The levels of nitrogen found in the blood as a result of protein activity.
  • Creatinine: As mentioned above, the levels of creatinine present in the blood can help us to know about the glomerular filtration rate.
  • Uric Acid: Uric acid is the waste product found in the body. It is formed due to chemical reactions and food digestion.
  • Albuminuria: Albuminuria is a protein that should be present in the blood and not in the urine. Its presence in the latter signifies the abnormality of the kidney in performing its functions of filtering and purifying the blood.
Risk/side effects of KFT Test

There are no side effects associated with the kidney function test. However, some pain might be felt in the area for a few days where the needle is inserted. It eventually fades away.

Interpreting the kidney function test results

Interpreting the kidney function test results

Interpreting the results of the kidney function test is important in order to evaluate the working of the organs and timely take appropriate health measures.
Keep in mind that factors like sickness and dehydration can impact your kidney function test results.
The table below mentions the normal ranges of different kidney function tests:

Blood Urea Nitrogen 6-24 mg/dl
Creatinine 0.7 – 1.3 mg/dl
Albuminuria 30 mg/g
Uric Acid 3.5 – 7.2 mg/dl


Abnormal results, including high levels of creatinine and urea, can signify short-term or long-term kidney failure.

Similarly, elevated uric acid levels can occur due to dehydration, alcohol intake, renal disease, deficiency of vitamin B12, obesity, etc.

Albuminuria levels higher than 30 mg/g indicate kidney disease, which is hampering the organ from performing its functions.
