Modernizing the flow of blood: Biomedical technicians, working knowledge and the transformation of Swedish blood centre practices.

ABSTRACT

The early 1980s saw a 'paradigm change' in how donated blood was handled and used by blood centres, hospitals and pharmaceutical companies. In Sweden, a five-year state-financed R&D programme initiated a swift modernization process, an alleged 'revolution' of existing blood centre practices. In this article, we use interviews and archival material to analyse the role of female biomedical technicians in this rapid technical and organizational change. In focus is their working knowledge, or savoir-faire, of blood, instruments and techniques. We give a detailed analysis of technicians' embrained and embodied skills to create safety in blood and its representations, handle contingencies and invent new procedures and techniques. These transformations are analysed as sociomaterial entanglements, where the doing and undoing of gender, sociomaterial practices, hierarchies of authority and expertise, and emotions are intertwined.
