Creatinine Pretreatment Lab Value
**Note 1:** Physician statement of Creatinine Pretreatment Lab Value can be used to code this data item when no other information is available.
**Note 2:** Record the lab value of the highest Creatinine test result documented in the medical record **prior to treatment**. The lab value may be recorded in a lab report, history and physical, or clinical statement in the pathology report.
**Note 3:** Record the blood or serum creatinine value for this data item. Do not use urine results to code this data item.
**Note 4:** The Model for End-Stage Liver Disease (MELD) is a numerical scale used to determine how urgently a patient with liver disease needs a liver transplant within the next three months. Results from three routine lab tests are used to calculate the MELD score. Creatinine, one of the tests, measures kidney function; impaired kidney function is often associated with severe liver disease.
**Note 5:** The same laboratory test should be used to record information in Creatinine Pretreatment Unit of Measure [NAACCR Data Item #3825].
