This is the Master Laboratory Test file. It contains the standardized Lab Test Name and its associated LOINC code. The Lab will
associate their local test to this file (^LAB(60,test#,1,specimen#)).
Per VHA Directive 2005-044, this file has been "locked down" by Data Standardization (DS). The file definition (i.e. data
dictionary) shall not be modified. All additions, changes and deletions to entries in the file shall be done by Enterprise
