Understanding the eGFR Blood Test and Its Role in Kidney Health
The eGFR blood test is essential in assessing kidney function and diagnosing potential kidney disease. Here's a breakdown of what it measures and why it’s important:
- What the eGFR Test Measures:
The eGFR test estimates how well your kidneys filter blood, specifically measuring the amount of creatinine—a waste product—filtered by your kidneys. The test uses factors such as age, sex, and race to calculate the eGFR. - Significance of eGFR Levels:
- Normal eGFR (90 mL/min or higher): Indicates healthy kidney function.
- Mildly reduced eGFR (60-89 mL/min): Early signs of kidney issues, requiring monitoring.
- Moderately reduced eGFR (30-59 mL/min): Kidney disease may be progressing; lifestyle changes or medications might be needed.
- Severely reduced eGFR (15-29 mL/min): Indicates advanced kidney damage; dialysis may be considered.
- Kidney failure (eGFR less than 15 mL/min): Requires immediate intervention, usually dialysis or a kidney transplant.
- Why It's Important:
Regular eGFR testing can help catch kidney problems early before they lead to kidney failure. For individuals with diabetes, hypertension, or a family history of kidney disease, early detection through eGFR testing is critical for managing the condition and slowing disease progression.
Recommended Tests
- Creatinine Test
Since eGFR is calculated based on creatinine levels in the blood, it is crucial to test creatinine to get an accurate estimation of kidney function.
Creatinine Test - Potassium Test
High potassium levels can indicate impaired kidney function, as damaged kidneys struggle to maintain the proper balance of potassium in the body.
