What is this test?

The Kidney Function Test is a blood test that measures levels of urea and creatinine in your blood. A sample of your blood is taken and analyzed in the lab.

What is kidney function?

The kidney is the body's filtration plant. Its role is to remove waste products from blood.

If the kidney is not functioning properly, levels of waste substances increase in the blood. This test measures - urea and creatinine, waste products that are present in very small quantities in the blood. If the levels of these substances (urea/creatinine) are higher than normal, it means your kidneys are not working properly

How do I know that I need a Kidney Function Test?

Do the Kidney Function Test if you are :

• Diabetic: Diabetes often leads to kidney damage, and so diabetics should get a kidney function test every few months.
• Swelling over the body: If the kidney is not working properly, it leads to fluid retention and swelling on the body. Kidney Profile is advised in such cases.
• Hypertension: People with high blood pressure may have kidney damage and should get this test
• Kidney Stones: People with kidney stones should periodically do the Kidney Function Test to make sure that the stones are not affecting filtration system of kidney.
• Frequent Urine Infections: If you get repeated urine infections, they may also affect your kidney
• Taking heavy medications: Some medicines can damage the kidney and reduce its function, so people on heavy medications should do this test.
• Patients who have cancer or HIV: HIV and cancer patients should routinely get blood tests done, of which one, is the kidney function test.

How is the test done?

What will be included in the report?

The report includes 4 parameters, as follows:

• Creatinine : Waste product of protein breakdown
• Urea : Waste product of protein breakdown
• Blood Urea Nitrogen : Calculated from Urea value
• GFR : Calculated from value of creatinine, gives estimation of filtration rate of kidney
