A Kidney Function Test (KFT) is a set of blood and urine tests used to assess ...
kidney health. These tests help determine how well the kidneys are filtering waste and maintaining electrolyte balance. Common tests include serum creatinine, blood urea nitrogen (BUN), glomerular filtration rate (GFR), and urine analysis. Early detection of kidney issues through KFT can prevent complications such as chronic kidney disease (CKD) and kidney failure.
Preparations Before the Kidney Function Test
Proper preparation ensures accurate results. Here are some essential steps:
Fasting: Some tests may require fasting for 8 hours.
Hydration: Drink enough water to ensure a proper urine sample.
Medication Adjustment: Inform your doctor about any medications, as some drugs can affect results.
Dietary Restrictions: Avoid excessive protein or potassium-rich foods before the test.
What to Expect During the Procedure
A Kidney Function Test involves simple blood and urine tests.
Blood Test: A small blood sample is taken from a vein, typically in the arm.
Urine Test: A random or 24-hour urine sample may be required to check for protein and other waste materials.
Duration: The entire process takes around 10-15 minutes, and results are usually available within 24-48 hours.
Why Doctors Recommend Kidney Function Test
Doctors recommend KFT for multiple reasons, including:
Monitoring kidney health in people with diabetes, high blood pressure, or a family history of kidney disease.
Diagnosing kidney disorders such as infections, stones, or chronic kidney disease.
Evaluating medication effects on kidney function, especially for long-term drug treatments.
Assessing kidney function before surgery or other medical procedures.
Conditions Diagnosed by Kidney Function Tests (KFT)
A KFT can detect various kidney-related conditions, including:
Chronic Kidney Disease (CKD): A gradual loss of kidney function.
Acute Kidney Injury (AKI): A sudden decline in kidney function due to dehydration, infections, or medication.
