What eGFR means in blood test?
Healthcare providers use estimated glomerular filtration rate (eGFR) to determine if you have kidney disease, and if so, what stage. eGFR measures your kidneys’ ability to filter toxins or waste from your blood.
Which eGFR equation is best?
Glomerular filtration rate (GFR) is the best overall index of kidney function. Normal GFR varies according to age, sex, and body size, and declines with age. The National Kidney Foundation recommends using the CKD-EPI Creatinine Equation (2021) to estimate GFR.
Is GFR same as creatinine clearance?
Creatinine clearance ( CrCl ) is an estimate of Glomerular Filtration Rate ( GFR ); however, CrCl is slightly higher than true GFR because creatinine is secreted by the proximal tubule (in addition to being filtered by the glomerulus).
What does 1.73 m2 mean?
Your eGFR is reported in millilitres per minute which is written as mL/min/1.73m2 (the “1.73m2” indicates a result expressed relative to body surface area). A normal GFR in a young adult is greater than 90 mL/min/1.73m2.
What is a normal creatinine level for a 73 year old woman?
A normal result is 0.7 to 1.3 mg/dL (61.9 to 114.9 µmol/L) for men and 0.6 to 1.1 mg/dL (53 to 97.2 µmol/L) for women. Women often have a lower creatinine level than men. This is because women often have less muscle mass than men. Creatinine level varies based on a person’s size and muscle mass.
How is EGFR calculated?
Modification of Diet in Renal Disease Study (MDRD) Equation. The MDRD equation has performed well in patients with chronic kidney disease.
Why would EGFR be high?
A eGFR below 60 for three months or more or a eGFR above 60 with kidney damage (marked by high levels of albumin in your urine) indicates chronic kidney disease.
What are normal EGFR levels?
The healthcare practitioner uses the result that applies to the particular patient in order to interpret the results correctly. A normal eGFR for adults is greater than 90 mL/min/1.73m 2, according to the National Kidney Foundation.
What is EGFR lab results?
Estimated Glomerular Filtration Rate (eGFR) A blood sample drawn from a vein in your arm; the eGFR is a calculated estimate of the actual glomerular filtration rate and is based on your blood creatinine level along with other variables such as your age, sex, and race, depending on the equation used.
