In this lesson, you will learn about GFR; what it measures as well as what levels are considered normal in a healthy human. The blood test and calculations used to determine GFR will also be described. Main Functions of the Kidney
A more widely available but less accurate alternative is the creatinine clearance test, which typically requires collection of urine over a 24-hour period.测定GFR的标准方法是测量外源性滤过标志物的清除率,例如奥他拉明的尿液清除率。一种更广泛但不太准确的替代方法是...

Perform a blood test to determine serum creatinine or serum cystatin C levels. Choose one of the four main methods of calculating GFR: CKD-EPI Creatinine Equation; CKD-EPI Creatinine-Cystatin Equation; CKD-EPI Cystatin C Equation; or MDRD equation. Select the values of the parameters α,...
