According to biomedical discourse, cord blood has been transformed from 'waste' to 'clinical gold' because of its potential for use in treatments. Private cord blood banks deploy clinical discourse to market their services to prospective parents, encouraging them to pay to bank cord blood as a form of 'biological insurance' to ensure their child's future health. Social scientists have examined new forms of (bio)value produced in biological materials emergent with contemporary biotechnologies. This paper contributes to this literature by examining the social and technical production of value in cord blood units collected for private banking. Value, in this paper is defined as a socio-cultural concept in which an object is made meaningful, or valuable, through its relations with social actors and within specific regimes of value. I draw on in-depth interviews with women who banked cord blood and key informants in private banks in Canada, to analyze how social actors produced cord blood as a valuable biological object. I show that a cord blood unit holds promissory value for women who bank and profit value for private banks and that these values are folded into each other and the biological material itself. Analyzing how specific cord blood units are made valuable provides insight into the multiple and possibly competing values of biological materials and the tensions that may arise between social actors and forms of knowledge during the valuing process.
