Hello, and thank you for requesting me.
The eGFR (non -African American) is a test that is ordered to check for early kidney damage and to monitor kidney function. It is usually ordered along with several other test when the kidney status is evaluated. When a person has either diabetes or hypertension or there is other reason to monitor the kidneys, it is usually ordered.
Signs of kidney disease is puffiness around the eyes or in the face, wrist, abdomen, thighs or ankles, urine that is foamy, bloody, or coffee-colored, decreased urine amounts, increased urination at night. In more severe kidney disease there may be a feeling of itchy skin, tiredness, loss of appetite and nausea, swelling in hands and feet and numbness, darkened skin, and muscle cramps.
