Who We Are
Fassisi is an owner-managed company in Göttingen with over 15 years of experience in veterinary diagnostics. As a 100% independent manufacturer, we develop and produce our rapid test systems entirely in Germany. Many members of our team spend their free time in the very places where our customers work every day: in the barn, at the riding arena, or walking their dogs. This shapes the way we approach diagnostics.
What We Do
We develop rapid tests for on-site diagnostics in small and large animals. Our tests deliver results in 10 minutes—no lab, no equipment, and no ongoing costs. The spectrum ranges from diarrhea diagnosis to infection screening and vaccine titer testing. With more than 30 products, we cover the most common diagnostic needs in veterinary practice.
Contract Manufacturing & OEM Production
In addition, we are an experienced partner for contract development and OEM production. As a full-service provider, we implement custom test systems—from feasibility studies through to approved series production. International partners in the diagnostics, pharmaceutical, and agricultural sectors rely on our development expertise.
Why Us
Quality is not just a promise—it’s our business model. We manufacture in accordance with GMP guidelines and are ISO 9001:2015 certified. We are one of the few companies to hold a manufacturing license under the Animal Diseases Act. Every batch is tested and approved at our facility in Göttingen.
As an owner-managed company, we make decisions quickly and without red tape. For our customers, this means: short decision-making processes, reliable delivery capabilities, and a team that shares a passion for healthy animals. Millions of tests sold in over 30 countries confirm our reliability.
