Understand the Value of a KFT (Kidney Function Test)
KFT helps detect early signs of kidney damage or disease, monitor existing kidney conditions, and guide treatment decisions. It’s especially recommended for individuals with diabetes, high blood pressure, or a family history of kidney disorders.
 Breakdown of the KFT Components
A typical Kidney Function Test includes several important parameters:
-
Blood Urea Nitrogen (BUN): Measures the amount of nitrogen in your blood that comes from urea — a waste product formed by the liver. High levels may indicate kidney dysfunction or dehydration.
-
Serum Creatinine: Creatinine is a waste product from muscle metabolism. High levels suggest impaired kidney function or chronic kidney disease (CKD).
-
Uric Acid: Excess uric acid can be a sign of kidney inefficiency or may contribute to gout and kidney stones.
-
eGFR (Estimated Glomerular Filtration Rate): This is a calculated value that estimates how well your kidneys are filtering blood. A lower value may indicate reduced kidney function.
-
Electrolytes (Sodium, Potassium, Chloride): These minerals are crucial for fluid balance and nerve/muscle function. Imbalances may indicate kidney or adrenal issues.
-
Calcium & Phosphorus (in some panels): Often included to assess kidney-related bone and mineral disorders.
Ranges for a Healthy KFT
Note: Reference ranges can vary slightly depending on the lab.
| Parameter | Normal Range |
|---|---|
| BUN | 7–20 mg/dL |
| Serum Creatinine | 0.6–1.3 mg/dL (men), 0.5–1.1 mg/dL (women) |
| Uric Acid | 3.5–7.2 mg/dL (men), 2.6–6.0 mg/dL (women) |
| eGFR | >90 mL/min/1.73m² (Normal) |
| Sodium | 135–145 mEq/L |
| Potassium | 3.5–5.0 mEq/L |
| Chloride | 96–106 mEq/L |
Why Choose a Timely KFT?
Early diagnosis of kidney issues allows for better management and may prevent permanent damage. A timely KFT is valuable for:
-
Monitoring kidney health in diabetic or hypertensive patients
-
Detecting chronic kidney disease (CKD) in early stages
-
Managing fluid and electrolyte imbalances
-
Assessing effects of medications that may impact the kidneys
-
Evaluating fatigue, swelling, or urinary issues
 Stay Proactive with Kidney Health
Your kidneys quietly do the essential work of keeping your body in balance. Routine KFT screenings ensure you stay ahead of potential problems. If your test shows abnormal values, consult your physician promptly for personalized care and treatment.
Notes
-
Reference ranges can slightly vary based on lab standards, age, and altitude.
-
Always interpret values in consultation with a qualified physician.
