In vitro & in vivo Toxicology Services

The GBA Pharma service portfolio on in vitro and in vivo toxicology offers you a complete workflow to de-risk either your early stage drug discovery or late stage development programs. In vitro toxicology assays are performed in-house in a quality controlled way. In vivo toxicology studies according to national and international guidelines are available on rodent and non-rodent species in cooperation with our trusted partner.
