Estimated GFR is a method that helps identify chronic kidney disease, and results for African-Americans have different values than non-African-Americans. Doctors take age, gender, and race into consideration when screening for eGFR, the National Kidney Disease Education Program states.
The eGFR method produces a measure of kidney function that is more useful clinically than looking at serum creatinine only, NKDEP claims. Doctors can report eGFR when they test for serum creatinine measurements to get a better picture of how well the kidney functions. Typically, medical workers divide results into an African-American group and a non-African American group. Measurements of eGFR for African -mericans vary compared to results for people of other ethnic groups. The overall eGFR may be higher in African-Americans.
A normal eGFR level hovers around a unit of 60 or more, the American Kidney Fund says. Low eGFR indicates kidney disease. A test for eGFR may not be accurate for people younger than 18 years of age, pregnant women, or muscular and overweight people. Along with eGFR screenings, doctors can test for chronic kidney disease by examining blood sugar levels, blood pressure, and content in the blood and urine. Patients seeking to curtail kidney disease should get regular exercise, avoid smoking and consume a diet low in salt and fat.
