The Unified Information System of Russian Laboratory Service Inventory is one of the most priority projects of the Federation of Laboratory Medicine. The goal of the development of this System is data collection about Russian medical laboratories in a structured way, for their further comprehensive analysis, that will allow to improve quality of laboratory service work. In the System detailed information about each laboratory will be stored: its description and staff information, laboratory activity, equipment and its use, analyses flow. Among other tasks of the System there are simplification of filling in forms and high control of input data. Besides, analytics will be able to build comprehensive reports about the laboratory service. So, due to using innovative solutions in the sphere of medicine informatization, the System will give the opportunity of quick access to actual consolidated information over all the laboratory service, and also the opportunity of carrying out multivariable analysis of its condition.
