CaliberLIMS LDMS functionality facilitates registration and maintenance of documents with proper version control. LDMS stands for Laboratory Documents Management System. This functionality is very handy where a variety of documents are maintained and used as authentic reference material for the lab personnel. These documents may be literature of equipment or products, standard operating procedures (SOPs), and other reference materials. In order that the documents remain current with authentic version control, and also to meet the regulatory requirements, the lab documents need to be regularly updated. The Modification facility affords keeping the current validity of the documents with correct and updated versions.
