A member asked:

What comparison or correlation can be made between the creatinine clearance test and gfr?

A doctor has provided 1 answer

Estimate: The true creatinine clearance test, which requires a timed urine, is much more accurate as a measure of glomerular filtration rate than is the crude and subscientific estimate obtained from just a spot serum creatinine.
