What are the tests included in KFT? Completely Explained

Importantly, the kidney filters the blood and separates the waste products from the body as urine. Thus, it helps in maintaining pH balance and fluid balance in the body.

In the kidney function test, some basic components are measured to scan kidney function.

• Serum Creatinine Test: This is a blood test specially performed to evaluate the proliferation of creatinine in the body. Creatinine is a waste product formed from the breakdown of muscles. When there is higher storage of creatinine in the body, this can be assessed as a kidney problem.
• Blood Urea Nitrogen: The main purpose of this test is to check the waste product urea and the amount of nitrogen in the body's blood. Urea is the nitrogenous waste product of metabolism protein, and an excess of urea in the blood can cause diseases.
• Uric Acid Test: This test gives the value of uric acid in the blood. It is a waste product excreted from the body by the kidneys through urine. It is also essential for building blocks of DNA. The uric acid crystals can also accumulate in the kidney and contribute to the formation of kidney stones.
• Other parameters: Several mineral tests such as calcium, sodium, and chloride in the Kidney Function Test are optional parameters to indicate kidney problems like kidney stones.

• Medication: Inform your doctor about prescription medicines, vitamin supplements, and over-the-counter medicines you are taking to avoid interfering with the test results.
• Dietary Restrictions: Do not eat high-protein meals before the test to avoid any increase in BUN levels.

What is the procedure for a kidney function test (KFT)?

The procedure for a kidney function test (KFT) usually takes less than 10 minutes and includes the following:

• Sample Collection: A lab technician will collect blood from a vein in your arm using a sterile needle. If needed, your healthcare provider may also suggest a urine sample collection to detect bacteria or yeast causing the infection.
• Labeling: The expert will transfer the blood into a vial or test tube, label it, and send it to the laboratory for analysis.
• Other considerations: The kidney function test (KFT) measures the creatinine, BUN, GFR (Glomerular Filtration Rate), and electrolytes like potassium and sodium. The urine tests may include an albumin-to-creatinine ratio or other specific evaluations. This is to screen for high albumin levels, known as albuminuria. Your healthcare provider may suggest this screening if he suspects you have a higher risk of kidney disease, including diabetes, high blood pressure, or a family history of kidney problems.

Note: The KFT test results are typically available within 10 hours. Discuss your test results with your doctor for further analysis and guidance.
