Reporting the eGFR and its implication for CKD diagnosis.

The process of diagnosing chronic kidney disease using the estimated GFR involves several pitfalls.

Until a more reliable method is available to estimate the GFR, the current chronic kidney disease classification should be revised by reducing the central role of the GFR cutoff levels.
