Patient safety protocol

We consider the safety of our patients and our professionals to be of the utmost importance, therefore, in accordance with the current regulations in force, we implement several protective measures against COVID-19 in our Institute, which you can read about in detail HERE. A negative PCR test is required for oral and other body cavity examinations or interventions if the patient had a positive PCR test in the last 3 weeks prior to the test.

The high level of interest in coronavirus testing has proportionally increased the workload of our telephone customer service. In order to improve our service, we provide a dedicated telephone line for corona virus test appointments: +36 1 999-1727
At the above telephone number - on weekdays between 8 a.m. and 8 p.m. - our colleagues only book appointments for coronavirus testing.

In order to provide mandatory information to the National eHealth Infrastructure (EESZT) in accordance with legal regulations, the basic condition for starting care for all Hungarian citizens is to provide the number of the social security identification card ("TAJ kártya") and to provide credible proof of your personal data. In the case of foreign nationals who do not have a TAJ, the number of the foreign travel document will be recorded.
