The project was conducted in a collaboration with the community health care centre Trbovlje, Labena and the Faculty of Medicine (University of Ljubljana). We have developed Labek, a system that aids the work process performed within the diagnostic laboratories of community health care centres. Labek complements the laboratory information systems which are currently used in these laboratories to perform routine laboratory work. The proposed system allows the laboratory personnel to manage the supply of materials and chemicals, perform new orders and manage samples not directly related with the routine laboratory work.
