Your allergy is our concern

We take allergy science and make it simple to help you live the life you want. Unleash your full potential with klarify.


Bright young allergy company with a pioneering history

klarify was born in 2018 to help people with allergy. But our parent company ALK is much older. Pharmacist Peter Barfod and Dr Kaj Baagøe were the first in Denmark to turn an everyday substance into an extract for allergy testing. It was 1923 and they chose goose feathers. (Nobody knew then it was dust mites in pillows and duvets making people sneeze.) Peter Barfod's lab became ALK, now a world leader in treatments for allergy.
