Creatinine Levels GFR Calculator

CKD-EPI Equation:

\[ eGFR = 141 \times \min(Scr/\kappa, 1)^\alpha \times \max(Scr/\kappa, 1)^{-1.209} \times 0.993^{age} \times (1.018 \text{ if female}) \times (1.159 \text{ if black}) \]

1. What Is Creatinine Levels GFR Calculator?

The Creatinine Levels GFR Calculator uses the CKD-EPI equation to estimate glomerular filtration rate from serum creatinine levels, providing an accurate assessment of kidney function.

2. How Does The Calculator Work?

The calculator uses the CKD-EPI equation:

\[ eGFR = 141 \times \min(Scr/\kappa, 1)^\alpha \times \max(Scr/\kappa, 1)^{-1.209} \times 0.993^{age} \times (1.018 \text{ if female}) \times (1.159 \text{ if black}) \]

Where:

\( Scr \) — Serum creatinine (mg/dL)
\( \kappa \) — 0.7 (female) or 0.9 (male)
\( \alpha \) — -0.329 (female) or -0.411 (male)
\( age \) — Age in years
1.018 — Female multiplier
1.159 — Black race multiplier

3. Importance Of GFR Calculation

Details: GFR calculation is essential for detecting kidney disease, monitoring kidney function, and guiding appropriate medical treatment.

4. Using The Calculator

Tips: Enter accurate serum creatinine values in mg/dL, provide correct age, and select appropriate gender and race for precise results.

5. Frequently Asked Questions (FAQ)

Q1: What Is Normal Creatinine Level?
A: Normal serum creatinine levels are typically 0.6-1.2 mg/dL for men and 0.5-1.1 mg/dL for women.

Q2: How Often Should GFR Be Tested?
A: Frequency depends on individual risk factors, but annual testing is recommended for those with diabetes, hypertension, or family history of kidney disease.

Q3: Can Diet Affect Creatinine Levels?
A: Yes, high protein intake and certain supplements can temporarily increase creatinine levels.

Q4: What Factors Affect GFR Accuracy?
A: Muscle mass, diet, medications, and hydration status can all influence GFR calculations.

Q5: When To Consult A Doctor?
A: Consult a healthcare provider if eGFR is below 60 mL/min/1.73m² or if you have symptoms of kidney disease.
