Dehydration secondary to an inflammatory process with fever may cause a false increase in creatinine concentrations not related to actual kidney impairment, as in some cases associated with cholecystitis. Several medications and chromogens can interfere with the chemical assay. Creatinine secretion by the renal tubules can be blocked by some medications, again increasing measured creatinine.
