As kidney disease progresses, the level of creatinine in the blood rises. … WebSep 15, 2004 · In most cases, measurement of creatinine clearance using a timed (e.g., 24-hour) urine collection for assessment of the GFR is not more reliable than estimation using a prediction equation. 1, 2 ...
WebJun 5, 2024 · Both creatinine clearance and the serum creatinine can be used as a surrogate measure of the glomerular filtration rate. Serum creatinine increases as renal function decreases. This relationship is non-linear: i.e. significant changes in glomerular filtration can occur before this is reflected in the serum creatinine.
