Antimicrobial resistance testing

Expert support for antimicrobial profiling


AHVLA Scientific can provide up-to-date profiles for a wide range of currently marketed or research antimicrobials. We can carry out comparative studies between different antimicrobials and changes in resistance profile over time. These are suitable for product registrations, claim extensions or marketing.

Our tests are performed under ISO 17025. This ensures your data is of the highest standard of quality, impartiality and credibility for your customers and regulatory authorities.

Testing services

AHVLA has centres of expertise dedicated to antimicrobial testing and anaerobic work. Our techniques are continuously updated to ensure they are in keeping with advances in the human field as well as veterinary specialisation.

We routinely offer several minimum inhibition concentration (MIC) assays:
