Estimated Glomerular Filtration Rate (eGFR)

• The Estimated Glomerular Filtration Rate (eGFR) Test is a blood test used to assess kidney function by estimating how well the kidneys filter waste from the blood
• The eGFR is calculated using the serum creatinine level, age, gender, and sometimes race
• This Estimated Glomerular Filtration Rate (eGFR) Test is crucial for detecting early signs of kidney disease, monitoring kidney function in patients with known kidney conditions, and guiding treatment decisions to prevent further kidney damage

• The primary use of the eGFR test is to evaluate kidney function and diagnose kidney disease
• The Estimated Glomerular Filtration Rate (eGFR) Test helps doctors identify early stages of chronic kidney disease (CKD) before symptoms appear, allowing for timely intervention
• The eGFR is also used to monitor the progression of kidney disease, assess the effectiveness of treatments, and adjust medication dosages that are excreted by the kidneys

• Estimated Glomerular Filtration Rate (eGFR) Test measurement of serum creatinine, a waste product in the blood that the kidneys normally filter out
• Estimated Glomerular Filtration Rate (eGFR) Test calculation of the eGFR using a formula that considers serum creatinine levels, age, gender, and sometimes race
• Estimated Glomerular Filtration Rate (eGFR) Test interpretation of the eGFR value to assess kidney function

• The interpretation of eGFR results involves understanding the kidney's filtration efficiency. An eGFR of 90 mL/min/1.73 m² or higher is considered normal, while lower values indicate varying degrees of kidney dysfunction
• An eGFR between 60-89 may suggest early kidney disease, while values below 60 indicate more significant kidney damage or chronic kidney disease (CKD)
• eGFR values below 15 indicate kidney failure, requiring immediate medical intervention, such as dialysis or transplantation

• Results of the eGFR test are reported as a numerical value in milliliters per minute per 1.73 square meters (mL/min/1.73 m²)
• This value estimates the rate at which the kidneys filter blood
• Higher values indicate better kidney function, while lower values suggest impaired kidney function
• The results are used to determine the stage of kidney disease, guide treatment decisions, and monitor the effectiveness of interventions

Q. What is the Estimated Glomerular Filtration Rate (eGFR) test?
The eGFR test estimates how well your kidneys are filtering waste from your blood, helping to assess kidney function

Q. Why might I need an eGFR test?
Your doctor may recommend this Estimated Glomerular Filtration Rate (eGFR) Test if you have risk factors for kidney disease, such as diabetes or high blood pressure, or if you need to monitor an existing kidney condition

Q. How is the eGFR test performed?
The Estimated Glomerular Filtration Rate (eGFR) Test involves drawing a blood sample to measure your serum creatinine level, which is then used to calculate your eGFR

Q. What do the results of the eGFR test mean?
A high eGFR value indicates normal kidney function, while lower values suggest varying degrees of kidney dysfunction or disease

Q. How often should I have an eGFR test?
The frequency depends on your risk factors and existing health conditions. Your doctor will advise how often you should be tested based on your situation

Q. Can eGFR results change over time?
Yes, eGFR can fluctuate based on your overall health, kidney function, and any treatments you may be undergoing. Regular monitoring is important

Q. Do I need to prepare for the eGFR test?
No special preparation is needed, but it’s important to follow any specific instructions from your doctor, such as fasting if required
