Quality and reliability is what we aim for

GBD Gesellschaft für Biotechnologische Diagnostik mbH is internationally connected and globally active.

As a virological-scientific institute our focus is on the production of customized quality control samples for virus diagnostics and other areas of laboratory diagnostics.

Our purpose

The purpose of our work is to contribute to the continuous quality improvement and standardization of laboratory diagnostics. Our focus is on the production of control samples for virus immunology and virus genome detection. In order to enhance quality in this area, we produce selected sensitivity and specificity panels as well as panels for geno/subtyping and resistance determination of infectious pathogens for our customers.

For decades we have been a producer and strong partner in the preparation of EQA samples.

Our performance

In accordance with the current state of science and technology, we provide quality control materials adapted to the respective clinical/epidemiological situation.


Thanks to a broad collection of source material and a strong network, we are able to produce tailor-made test materials of the highest quality.

Our approach

Close cooperation with scientific partners and other collaborators is important to us. We guarantee the highest level of quality with a controlled and detailed proven manufacturing process - our samples pass through various internal and external testing phases.

Our credo

Working sustainably in a team with and for quality.


Due to our experience and our network, our outstanding strength is flexibility - in production and consulting.
