EQuIS is “The EDD Software”
EQuIS supports a wide variety of Electronic Data Deliverable (EDD) formats and various EDD designs are supported for specific sample types. EDDs are the basis for EQuIS workflows and are available on mobile, desktop, and cloud EQuIS modules. EQuIS EDDs have been in use in large government agencies for nearly two decades. The EQuIS Data Processor, EDP, is the most widely used EDD-enforcement tool in the world.
