Abstract: a System for calculating and emitting analytical data, particularly medically relevant analytical data, has a computer with an evaluation unit for analyzing information entered by the system user and for generating the analytical data, and an output medium provided at the user side. The evaluation unit is configured for interrogating and accepting information that can be entered at the user side such that the information can be entered autonomously by the user based on a number of inquiries which are predefined at the system side, and which can be selected with reference to each response, and which can be made available as an output to user via the output medium. The evaluation unit is configured for controlling an interactive information capture such that, depending on the running information compilation, specific inquiries can be formulated and shown to the user.
