What is GFR Equation Calculator?

The GFR Equation Calculator is a medical tool used to evaluate kidney function. Glomerular Filtration Rate (GFR) is a crucial indicator of kidney health, reflecting the amount of blood filtered by the glomeruli per minute. This calculator estimates GFR using parameters such as age, gender, race, and serum creatinine levels, employing formulas like MDRD, CKD-EPI, or Cockcroft-Gault.

Usage Guidelines

• Accuracy of Input Information: Ensure that the data for age, gender, race, serum creatinine, etc., are accurate, as these parameters directly affect the calculation results.
• Choosing the Appropriate Formula: Select the suitable GFR calculation formula (e.g., MDRD, CKD-EPI, or Cockcroft-Gault) based on the patient's specific situation.
• Consistency of Units: The units for serum creatinine should be consistent (typically mg/dL or μmol/L). If using different units, convert them first.
• Consulting Physician Advice: The results provided by the GFR calculator are for reference only and cannot replace professional medical advice. Always consult a physician before making any medical decisions based on the results.
• Regular Monitoring: For patients with kidney disease or at risk of kidney disease, regular monitoring of GFR is essential for managing health effectively.

Result Analysis

The GFR value obtained from the calculator can be interpreted as follows:

• Normal GFR (≥90 mL/min/1.73m²): Indicates normal kidney function.
• Mildly Decreased GFR (60-89 mL/min/1.73m²): May indicate early kidney disease; further testing may be required.
• Moderately Decreased GFR (30-59 mL/min/1.73m²): Suggests moderate kidney disease; medical intervention may be necessary.
• Severely Decreased GFR (15-29 mL/min/1.73m²): Indicates severe kidney disease; close monitoring and treatment are essential.
• Kidney Failure (<15 mL/min/1.73m²): Indicates kidney failure; immediate medical attention is required.
