Overview

Differentiating chronic renal failure from acute renal failure and from the condition of having an increased BUN with a normal GFR are the most important diagnostic step in evaluating a patient with raised serum creatinine levels, as these conditions can be treated with therapy specific to the underlying etiology.

Distinguishing chronic renal failure from acute renal failure

Elevated creatinine levels from recent weeks or months suggest that the current disease process is more acute and hence reversible. On the other hand, long standing elevated serum values suggests a chronic disease process.
Even if the elevated serum creatinine levels are chronic, there is a possibility of the patient having a superimposed acute process over a chronic condition such as: a urinary tract obstruction, infections, extra cellular fluid volume depletion, or nephrotoxin exposure.
If the patient's history suggests an array of recent onset symptoms e.g:fever, rash and/or polyarthralgia, it can be safely concluded that the renal insufficiency is a part of an acute process.

Distinguishing chronic renal failure from an increased BUN with normal GFR

The key differentiating factor between the condition of an increased BUN with a normal GFR and chronic renal failure is a normal glomerular filtration rate (GFR).

Other differentials

Uremia due to chronic renal failure should be differentiated from other diseases causing hypertension and hypokalemia for example:^[1]^[1]^[2]^[3]^[4]^[5]^[6]^[7]^[8]^[9]^[10]^[11]^[12]^[13]^[14]^[15]
