Since the foundation of MADx in 2016, we produce reliable allergy and food intolerance tests for diagnostic clinics, laboratories, doctors' practices and hospitals.
In the beginning there was a vision to improve and modernise immunodiagnostics. Scientists - like our founders, Dr. Christian Harwanegg and Dr. Christian Sascha Dennstedt - always strive for disruptive innovation. So after more than a decade with leading companies in the field Dr. Christian Harwanegg decided to start his own enterprise in 2016. The goal was clear: The newly founded company MADx (Macro Array Diagnostics) should create an allergy test that is supposed to be better, more efficient and easier to use than the ones of the competition. In addition, we wanted to offer the entire value chain from test material to evaluation and interpretation of results, all under one roof.
A mammoth project? Without question, but worth the effort: for sure. Over the past years, we have launched two generations of the ALEX (Allergy Xplorer), which now tests for around 300 different allergens - in a single, non-invasive step. Our panel covers nearly 100% of the world's relevant allergens. We have developed proprietary hardware and software solutions that define new standards. We are constantly innovating and expanding our portfolio, as most recently with the FOX (Food Xplorer), a solution for the detection of IgG-mediated food intolerances.
