DAO-REA is an innovative laboratory diagnosis kit for the quantitative detection of the activity of the Diamine Oxidase enzyme in serum and plasma by means of a radioextraction assay method.

The assay requires specialized diagnostic equipment – a beta counter.

Nowadays, the activity of the DAO enzyme is determined in the laboratories of the MEDIREX GROUP a.s., an immunology laboratory of the Onkologický ústav sv. Alžbety in Bratislava and in the laboratory of the Klinická biochémia in Žilina.
