Introduction
Estimated Glomerular Filtration Rate Creatinine-CystatinC (eGFRcr-cys) and BUN (Urea) are key diagnostic tools for evaluating kidney function and metabolic health. Comparing these markers helps healthcare providers determine the most appropriate test based on specific clinical conditions like renal filtration efficiency, nitrogen waste levels, or chronic kidney disease risk.
What Is Estimated Glomerular Filtration Rate Creatinine-CystatinC (eGFRcr-cys)?
Estimated Glomerular Filtration Rate Creatinine-CystatinC (eGFRcr-cys) measures how well your kidneys remove nitrogen-based waste (urea) from the blood. It’s often used to screen for dehydration, high protein intake, or impaired renal clearance.
What Is BUN (Urea)?
BUN (Urea) provides complementary insights into kidney performance, especially for estimating glomerular filtration rate or understanding renal stress through ratio-based or creatinine-based formulas.
Comparison Table
Category | Estimated Glomerular Filtration Rate Creatinine-CystatinC (eGFRcr-cys) | BUN (Urea) |
|---|---|---|
Primary Function | Assesses nitrogen waste (urea) | Estimates filtration rate or renal output |
Diagnostic Relevance | Monitors hydration, protein metabolism | Detects early kidney dysfunction |
Test Type | Blood test | Blood test |
Sample Required | Blood sample | Blood sample |
Preparation Needed | None typically required | Fasting optional but not required |
Optimal Range | 6–20 mg/dL (BUN) | Varies by method, age, sex |
Factors That Influence | Dehydration, diet, bleeding | Muscle mass, kidney health, hydration |
Clinical Use Cases | Kidney disease, protein disorders | CKD staging, routine renal panels |
When to Test
Your provider may recommend testing Estimated Glomerular Filtration Rate Creatinine-CystatinC (eGFRcr-cys) and BUN (Urea) if you're experiencing symptoms like swelling, fatigue, decreased urine output, or changes in hydration. They're also used for ongoing monitoring in patients with hypertension, diabetes, or known kidney conditions.
FAQs
Can I test for Estimated Glomerular Filtration Rate Creatinine-CystatinC (eGFRcr-cys) and BUN (Urea) together?
Yes, these tests are often bundled in comprehensive metabolic panels or renal panels.
Which is more accurate for early kidney damage?
BUN (Urea) may offer better insight into glomerular filtration rate, a key indicator for early-stage renal disease.
What affects test accuracy?
Hydration status, medications, and recent diet can all impact values for both Estimated Glomerular Filtration Rate Creatinine-CystatinC (eGFRcr-cys) and BUN (Urea).
