About Divisions

Bio-Diagnostics has grown over the years and now has multiple areas of specialty. Each of these divisions are all developed from our expertise in Immunology. Bio-Diagnostics has been a leading UK manufacturer and supplier of innovative diagnostics since November 1979, and we continue to focus and grow our interests beyond Infectious Disease, Autoimmunity, Immunohistochemistry, and Dermatology, (which includes allergy testing).


I found Bio-diagnostics more than helpful, replacing all our allergens in a very quick and efficient way, reducing the complexity of ordering and providing an excellent service to us.

Melanie Paddon, OPD, Circle, Bath.

The company and individual staff are very attentive and efficient at responding to our needs. I would not hesitate in recommending Bio-diagnostics to provide a solution for any potential customers. Thanks Bio-diagnostics.
