GFR Calculator
Description of Glomerular Filtration Rate (GFR): Glomerular filtration rate (GFR) is a measure of how well the kidneys are filtering waste from the blood. It specifically measures the volume of fluid filtered by the glomeruli per unit of time. Glomeruli are the tiny filters in the kidneys that help remove waste and excess fluids from the blood, forming urine.
Role of GFR: GFR is an important indicator of kidney function. It helps healthcare providers assess how well the kidneys are working and can help diagnose and monitor kidney diseases and conditions such as chronic kidney disease (CKD) and acute kidney injury (AKI). A decrease in GFR can indicate kidney damage or dysfunction.
Using the GFR Calculator Tool:
- Input Serum Creatinine: Enter the serum creatinine level in the input field. Serum creatinine is a waste product that is typically measured in blood tests to assess kidney function.
- Enter Age: Enter your age in years. Age is a factor in the calculation of GFR.
- Select Gender: Select your gender from the dropdown menu. Gender is also a factor in the calculation of GFR.
- Select Unit: Select the unit of measurement for creatinine. You can choose between Indian, US, or British units.
- Calculate GFR: Click the "Calculate GFR" button to calculate the estimated GFR based on the entered values.
- Interpretation: The tool will display the calculated GFR value and provide an interpretation of the result. The interpretation is based on the color scale provided: green for normal or high GFR, yellow for mildly decreased GFR, orange for moderately decreased GFR, and red for severely decreased GFR.
- Consultation: It's important to note that the calculated GFR is an estimate and may not reflect the actual GFR. Always consult with a healthcare professional for a proper evaluation of kidney function and interpretation of GFR results.
GFR Information
How GFR is Used and Interpreted:
Assessing Kidney Function: GFR is used to assess how well the kidneys are functioning. A normal GFR indicates that the kidneys are filtering waste from the blood effectively, while a decreased GFR may indicate kidney damage or dysfunction.
Diagnosing Kidney Disease: GFR is an important indicator in the diagnosis of kidney diseases such as chronic kidney disease (CKD) and acute kidney injury (AKI). A persistent decrease in GFR over time may indicate the progression of kidney disease.
Monitoring Kidney Disease: GFR is used to monitor the progression of kidney disease and the effectiveness of treatment. Regular monitoring of GFR helps healthcare providers adjust treatment plans and interventions as needed.
Interpreting GFR Values: GFR values are typically interpreted as follows:
- Normal GFR: A GFR of 90 mL/min or higher is considered normal kidney function.
- Mildly Decreased GFR: A GFR between 60 and 89 mL/min may indicate mild kidney dysfunction.
- Moderately Decreased GFR: A GFR between 30 and 59 mL/min may indicate moderate kidney dysfunction.
- Severely Decreased GFR: A GFR below 30 mL/min may indicate severe kidney dysfunction.
Color Scale Interpretation: The color scale provided in the tool can help interpret GFR values based on disease severity:
- Green (Normal): GFR is normal or high, indicating normal kidney function.
- Yellow (Mildly Decreased): GFR is mildly decreased, indicating mild kidney dysfunction.
- Orange (Moderately Decreased): GFR is moderately decreased, indicating moderate kidney dysfunction.
- Red (Severely Decreased): GFR is severely decreased, indicating severe kidney dysfunction.
Clinical Judgment: It's important to note that GFR values should be interpreted in the context of the individual's overall health, medical history, and other clinical factors. A healthcare professional should interpret GFR values and recommend appropriate treatment or further evaluation if necessary.
