Creatinine (Jaffé-method)
Creatinine is an excretion product of the kidney, therefore increased plasma values indicate impaired kidney function.

Each laboratory should check if the reference ranges are transferable to its own patient population and determine own reference ranges if necessary. For diagnostic purposes, the results should always be assessed with the patient’s medical history, clinical examinations and other findings.
