Arden Syntax as a standard for knowledge bases in the clinical chemistry laboratory

Arden Syntax, a standard specification for defining and sharing modular health knowledge bases, is introduced in the clinical chemistry laboratory. A decision support system is constructed and integrated with a laboratory information system for validation of test results with the delta check method. Adopting the Arden Syntax makes it easier to share knowledge bases between laboratories. Tools for handling Arden Syntax knowledge bases and methods for decision support system implementation and integration with a laboratory information system are available today.
