In-Vivo DMPK
Flexibility & Speed
Flexibility in study design and meeting demanding time lines is the strength of the GBA Group In-Vivo team. We offer DMPK studies in mice, rats, guinea pigs and hamsters. The GBA Group offers include complete workflow studies (in-life part, bioanalysis and PK evaluation, biomarker assessment ). Non-GLP bioanalysis and GLP bioanalysis of samples from all animal species can be performed.
