Creatinine Pretreatment Lab Value
Description
Creatinine Pretreatment Lab Value, an indicator of kidney function, is required to calculate the Model for End-Stage Liver Disease (MELD) score, which is used to assign priority for liver transplant. Creatinine concentration in blood is a marker of renal function. Elevated levels are associated with severe liver disease. Creatinine can be measured in blood serum or urine, but these data items apply to blood levels only. Do not code urine creatinine or creatinine clearance in this field. There are two methods of describing creatinine levels in the blood, weight in grams (milligrams per deciliter), usually used in the US, and molecular count in moles (micromoles per liter) in Canada. Conversion: 1 mg/dL = 17.1 umol/L. Code the unit of measure used by the facility laboratory. 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. Results from three routine lab tests are used to calculate the MELD score. Bilirubin, one of the tests, measures how effectively the liver excretes bile. The purpose of this scale was to help prioritize patients for liver transplant by estimating their risk of dying while waiting for transplant. There are several related data items that are defined to record the MELD score. * 3813: Bilirubin Pretreatment Total Lab Value * 3814: Bilirubin Pretreatment Unit of Measure * 3824: Creatinine Pretreatment Lab Value * 3825: Creatinine Pretreatment Unit of Measure * 3860: International Normalized RatioNotes
**Note 1:** **Physician Statement** * Physician statement of Creatinine Pretreatment Lab Value can be used to code this data item when no other information is available. **Note 2:** **Pretreatment results only** * Record this data item based on a blood test performed at diagnosis (pre-treatment). Use the highest value available * Record the blood or serum creatinine value for this data item * Do not use urine results to code this data item. **Note 3:** **Related data item** * The same laboratory test should be used to record information in the related data item data item 3825: Creatinine Pretreatment Unit of Measure.| Code | Description |
