IntroductieIntroductie
At what level of creatinine does a 65-year-olddiabetic, hypertensive white woman weighing 50kilograms have chronic kidney disease (CKD)?
> 83 µmol/L?
> 133 µmol/L?
> 177 µmol/L?
At what level of creatinine does a 65-year-olddiabetic, hypertensive white woman weighing 50kilograms have chronic kidney disease (CKD)?
77% of physicians said:
Creatinine > 133 µmol/L (>1.5 mg/dL)
Actual eGFR at this creatinine =37 mL/min/1.73m2
At what level of creatinine does a 65-year-olddiabetic, hypertensive white woman weighing 50kilograms have chronic kidney disease (CKD)?
77% of physicians said:
Creatinine > 133 µmol/L (>1.5 mg/dL)
Actual eGFR at this creatinine =37 mL/min/1.73m2
Creatinine = 83 µmol/L (0.94mg/dL)
eGF R = 60 mL/min/1.73 m2

with CKD are aware they have the disease

Why? creatinine reference intervaldoes not easily correlate with GFR
