In this study, we focus on identifying the context-specific characteristics related to the use and adoption of a bioactive innovation. Through qualitative methodology the study focuses on the existing practices of point of care testing (POCT) in the human and pet health care and wellness markets. The empirical data was collected in Finland through individual interviews, target group discussions, and self-documentation packages. Our results show that innovation characteristics are reflected through the events of existing practices in the field. We conclude our findings by presenting a practice-based framework for the adoption of an innovation, highlighting the role of events in practices as well as their interaction with actors and innovation characteristics. This framework allows us to suggest that the acceptance of an innovation is closely connected with the acceptance of existing and emerging practices.
