The MicroBioS Team is composed of qualified and motivated veterinarians, molecular biologists and lab technicians in a good mixture to combine broad knowledge, long-year experience and new ideas and techniques. With our expertise we are able to provide a high-quality service for our customers.


Our vision: the delivery of reliable analytical results, competent support and the long-term confidence of our customers.

We are reliable in routine work, but also flexible and open for customer specific questions and projects.

We develop our own test protocols to provide the highest possible sensitivity in combination with high specificity. In order to achieve this, the fastest and cheapest solution is not always the best option.

We critically analyze our own methods and results and are checked regularly by external labs.

We are a local partner for our customers to ensure a personal and straightforward contact as well as a short transport distance.

We provide a customer-oriented service and are at the same time a good employer for our team. Only those who love their work, can do a good job.

This is our daily motivation for providing a high-quality service for our customers.
