Metabolic / Electrolytes
Also known as: estimated GFR, eGFR, calculated glomerular filtration rate
Contact your doctor if you experience severe swelling, extreme fatigue, nausea, vomiting, or significant changes in urination. These could be signs of worsening kidney function that require immediate medical attention.
This test checks how well your kidneys clean your blood. Your kidneys have tiny filters. These filters take out waste and extra water from your blood.
Your doctor orders this test to check for kidney problems. It helps them see how bad any kidney issues might be. This test also checks your kidney health if you have conditions like diabetes or high blood pressure.
eGFR results are estimates, and normal ranges can vary depending on the lab, your age, sex, and other factors. Your doctor will interpret your results in the context of your overall health.
