Preventive examinations are necessary in all age groups. For children they are even regulated in detail in many countries.

Adults widely accept that seeing a doctor once in a while is a good idea, but it is not easy to plan a protocol. The physician's dilemma is that unnecessary tests should not be performed, as e.g. in case of a laboratory mistake they could lead to further unnecessary interventions and anxiety of the patient. We have heard about cases when slightly elevated values of liver enzymes led to ultrasounds, control blood tests, even liver biopsy. Stories like this ruin the reputation of medicine. For an ill person examinations have to be carefully planned according to complaints and symptoms. For a healthy patient the situation is not different. Preventive examinations may not be misused to produce patients who can be treated for illnesses we pretend they have.

We concentrate on the circulation, kidneys, metabolism, oncology. Blood pressure and EKG data have to be carefully evaluated, if necessary during long-term measurement. Blood and urine tests give valuable information about kidneys, liver and metabolism.
