Extended lab flags are configurable in js-i2b2/cells/CRC/ModLabValues/CRC_ModLabValues_config_data.js. By default no change should be noticed.

From Robert Bradford at UNC: "Provides support for an expanded set of lab flag values. List can be easily modified by users to support their needs or expanded to the full set of HL7/LOINC flag values. The expanded list is toggleable via an added config setting in the i2b2_ui_config.js.

It appears that only numeric lab results have the flag functionality included so only those files were modified."
