When you visit a health care service provider, your data is recorded in the patient information system, from where it is transferred to the Kanta Services. You can browse this data yourself in MyKanta. Social welfare and health care services do not use MyKanta, but they can view data stored in the Kanta Services using their own information systems.
More information about MyKanta is available in the kanta.fi online service.
