It is important to differentiate CRF from [[acute renal failure]] (ARF) because ARF can be reversible. Abdominal [[medical ultrasonography|ultrasound]] is commonly performed, in which the size of the [[kidney]]s are measured.  Kidneys in CRF are usually smaller (< 9 cm) than normal kidneys with notable exceptions such as in [[diabetic nephropathy]] and [[polycystic kidney disease]].  Another diagnostic clue that helps differentiate CRF and ARF is a gradual rise in serum creatinine (over several months or years) as opposed to a sudden increase in the serum creatinine (several days to weeks). If these levels are unavailable (because the patient has been well and has had no blood tests) it is occasionally necessary to treat a patient briefly as having ARF until it has been established that the renal impairment is irreversible.
Differentiating [[chronic renal failure]] from [[acute renal failure]] and increased [[Blood urea nitrogen]] with normal [[GFR]] is the most important diagnostic step in evaluating a patient with raised serum [[creatinine]] levels, as the latter two conditions can be treated with therapy specific to the underlying etiology.
 
==Acute and chronic renal failure==
*Previous measurements of [[serum creatinine]]: Normal [[creatinine]] levels from recent months or years suggests that the current disease process is more acute and hence reversible. On the other hand, long standing elevated values suggests a chronic disease process.
*Even if the elevated [[serum creatinine]] levels are chronic, there is a possibility of superimposed acute process over a chronic condition e.g: urinary tract obstruction, infections, extra cellular fluid volume depletion, nephrotoxin exposure.

Overview

Differentiating chronic renal failure from acute renal failure and increased Blood urea nitrogen with normal GFR is the most important diagnostic step in evaluating a patient with raised serum creatinine levels, as the latter two conditions can be treated with therapy specific to the underlying etiology.

Acute and chronic renal failure

  • Previous measurements of serum creatinine: Normal creatinine levels from recent months or years suggests that the current disease process is more acute and hence reversible. On the other hand, long standing elevated values suggests a chronic disease process.
  • Even if the elevated serum creatinine levels are chronic, there is a possibility of superimposed acute process over a chronic condition e.g: urinary tract obstruction, infections, extra cellular fluid volume depletion, nephrotoxin exposure.
