Interpretive DataBackground information for test. May include disease information, patient result explanation, recommendations, details of testing, associated diseases, explanation of possible patient results.
The µTASWako method is used. Results obtained with different assay methods or kits cannot be used interchangeably. The des-gamma-carboxy prothrombin (DCP) assay is intended as a risk assessment for the development of hepatocellular carcinoma in patients with chronic liver diseases. Elevated DCP values have been shown to be associated with an increased risk for developing hepatocellular carcinoma. Patients with elevated serum DCP should be more intensely evaluated for evidence of hepatocellular carcinoma. Results cannot be interpreted as absolute evidence of the presence or absence of malignant disease.
Medication containing vitamin K preparations may cause a negative bias of the DCP values. Medication containing vitamin K antagonist or antibiotic may cause a positive bias of the DCP values.
