The eGFR (estimated Glomerular Filtration Rate) blood test is one of the most important tools for assessing kidney function. It provides an estimate of how efficiently your kidneys filter waste from your bloodstream.
- What the eGFR Measures:
- The eGFR test is based on blood creatinine levels. Creatinine is a waste product from muscle activity, and high levels in the blood can indicate poor kidney function.
- The test takes into account factors like age, gender, race, and body size, providing a more personalized evaluation of kidney health.
- Interpreting eGFR Results:
- Normal Kidney Function: eGFR values of 90 or higher typically indicate normal kidney function. However, even with a normal eGFR, other symptoms or conditions may require closer monitoring.
- Mild Decline: eGFR values between 60-89 may suggest early kidney disease. At this stage, managing underlying conditions like diabetes or high blood pressure is crucial.
- Moderate to Severe Decline: eGFR values below 60 indicate significant kidney damage, with a higher risk for kidney failure. Values under 15 often point to end-stage kidney disease, where dialysis or a kidney transplant might be necessary.
- Importance of Monitoring:
- Regular eGFR testing is essential for anyone at risk for chronic kidney disease (CKD). Early detection through eGFR can prevent further damage with lifestyle changes or medications.
Recommended Tests:
- Creatinine Test
Creatinine levels are directly linked to kidney function, and this test complements the eGFR in diagnosing kidney issues.
Creatinine Test - Potassium Test
Kidney dysfunction often leads to imbalances in electrolytes like potassium, making this test important for monitoring related complications.
