In the section of the post analytical phase special pro-grams are needed in data preparation and presentation especially for test systems with large volumes of data (e.g., micro-assays, ‘omics’ data). Due to the increasing number of long-term patients or patients with a preventive medical checkup, different forms of medical reporting (e.g., cumulative reporting, graphic course) is necessary. Furthermore, adapted medical reporting is needed, e.g., in pathology or transfusion medicine, for patients with special antibodies as well as structured data transfer in the microbiology, particularly results from resistance testing. In this context it is necessary to link previous reports and measurement data. These reports and data must be provided by the LIS or specialized programs. When the medical report is finished it must be transmitted to the entries/patient. New software for a secure electronic transfer is needed. Paper-based transfer should be restructured and easy readable. Finally, the medical reports/measured values must be digitally archived, independently from the data format of the LIS so that it can be reread if a change in LIS occurs.
