Measurements of creatinine are used in the diagnosis of renal disease. Measurements of serum creatinine is useful in evaluation of kidney glomerular function and in monitoring renal dialysis. However, the serum level is not sensistive to early renal damage and responds more slowly than blood urea nitrogen (BUN) to hemodialysis during treatment of renal failure. The serum creatinine together with serum BUN is used to differentiate pre-renal, renal and post-renal (obstructive) azotemia since an elevated BUN with only slight to moderate elevation of creatinine suggests pre-renal or post-renal azotemia. Serum creatinine varies with the subject's age, body weight, and sex. It is sometimes low in subject with relatively small muscle mass, cachetic patients, amputees, and in older persons. A serum creatinine level that would usually be considered normal does not rule out the presence of impaired renal function.
