Public health is one of key priorities of any European Union country, including Latvia. This means not only high quality and high levels of treatment of diseases, but also the timely diagnosis and prevention. An important role here is regular preventive examinations that can be taken by the family doctor, if he is provided with the necessary medical technologies. Currently investigations and analysis are usually carried out by several health care institutions, because only in rare cases, family doctor has the set of diagnostic equipment and skills to evaluate the information obtained in the investigations. Usually the tests are carried out at different times and in institutions, possibly located at considerable distance from the residence of the person under investigation. Thus additional time and resources of the patient and the employer's is being spent time on the way to examination centers and waiting for the results as well as for appointment with the doctor's for collection and assessment.
