The German Zentralinstitut für kassenärztliche Versorgung built kvappradar as an online information portal on health apps for patients, doctors, and psychotherapists. Medexter’s app Hepaxpert, as a useful tool for physicians and patients, is now part of this portal. The app provides reliable interpretations of hepatitis serology test results. Just enter any findings for hepatitis A, B, and C serology and get a comprehensible interpretive text for any of the 61.520 possible constellations, even the extremely rare or complex ones.
