This paper analysis how health interventions in childcare diabetes, through HbA1c as ameasuring tool, creates, frames and defines different forms of value of life in a Swedish healthcare context. HbA1c, also known as glycated haemoglobin, is used in diabetes care tomonitoring children, and their families, care of diabetes. Because people with diabetes havehigher-than-normal level of glucose in their blood, they also produces more HbA1c. Havinghigh blood sugar over a longer period creates risks for having other complications anddiseases later on in life. This measuring tool is used as a useful test in health care to see if thechild and the family are managing the diabetes effectively or if they need help from theprofessionals – it can therefore be seen as a measurement that produces numbers andknowledge that have a direct impact on health. At the same time it also becomes a healthintervention focusing very much on the families, and the child’s, possibilities to manage, ontheir own, the diabetes in an everyday setting. This paper analysis, from ethnographicdescriptions, health care meeting where medical professionals are measuring HbA1c andtalking about HbA1c with families having a child with diabetes. The analysis focus also onpolicies in diabetes care in Sweden and how HbA1c are framed. Central questions: how isvalue of life created, framed and defined by HbA1c in different contexts? What potentialfutures are imbedded in HbA1c? What (un)equal lives can be analysed through HbA1c?
