| Parameter | Normal Range | Your Value | What High Means | What Low Means |
|---|---|---|---|---|
| Urea Blood Urea Nitrogen |
7 - 20 mg/dL |
High
Kidney disease, dehydration, high protein diet, heart failure, bleeding in GI tract.
|
Low
Liver disease, low protein diet, overhydration, pregnancy, malnutrition.
|
|
| Creatinine Serum Creatinine |
M: 0.7-1.3, F: 0.6-1.1 mg/dL |
High
Kidney disease, dehydration, muscle damage, high protein diet, medications (NSAIDs).
|
Low
Low muscle mass, liver disease, pregnancy, malnutrition, overhydration.
|
|
| eGFR Estimated Glomerular Filtration Rate |
> 60 mL/min/1.73m² |
High
Usually not a concern. May indicate high muscle mass or hyperfiltration.
|
Low
Kidney disease (CKD), chronic kidney disease. Lower values indicate worse kidney function.
|
|
| BUN/Creatinine Ratio Urea to Creatinine |
10:1 - 20:1 |
High
Dehydration, GI bleeding, high protein diet, heart failure, prerenal azotemia.
|

📄 Analyze My Full Report NowWhat is a KFT (Kidney Function Test)?
A Kidney Function Test (KFT) measures how well your kidneys are working. Your kidneys filter waste products from your blood. Abnormal values can indicate kidney disease, dehydration, or other conditions.
Key KFT Parameters Explained:
- Urea (BUN): A waste product from protein metabolism. High levels indicate poor kidney function or dehydration.
- Creatinine: A waste product from muscle metabolism. High levels indicate kidney disease.
- eGFR (Estimated Glomerular Filtration Rate): Estimates how well your kidneys filter blood. Low values indicate kidney disease.
- BUN/Creatinine Ratio: Helps differentiate between kidney and non-kidney causes of high creatinine.
CKD Stages Based on eGFR:
- Stage 1: eGFR ≥ 90 (Normal kidney function with evidence of kidney damage)
- Stage 2: eGFR 60-89 (Mildly reduced function)
- Stage 3a: eGFR 45-59 (Mild to moderate reduction)
- Stage 3b: eGFR 30-44 (Moderate to severe reduction)
- Stage 4: eGFR 15-29 (Severe reduction)
- Stage 5: eGFR < 15 (Kidney failure / ESRD)
When Should You Get a KFT?
- Swelling in feet or ankles
- High blood pressure
- Diabetes
- Changes in urination (frequency, color, amount)
- Family history of kidney disease
- Taking medications that affect kidneys
