An area of specialization in Switzerland is the medical check up examination. The performing medical check up centres in Switzerland are among the best in the world. Medical health checks can be provided during one day in some institutes even on Saturday or Sunday. The full medical check up takes about 4-8 hours. This general check up is recommended to people above 50 years – but a medical checkup can also be useful for younger people, especially when belonging to so called high risk groups. A physical check up can be performed in Zurich, Geneva, but also in other cities like Lucerne, Lausanne, Vevey, Montreux, Gstaad, St.Moritz, Interlaken, etc.
