Which hospital and where do you live? It's very unusual to happen in a hospital. FBS must have been done so you can simply get a need prick test so they can initiate interventions for you. Either way, the results will not be altered since you've been tested already. I'm a nurse and I work in a hospital with this management system, http://bioleen.com/en . It works a lot well, so you can include that in your recommendation later or complain. I wish this issue will never happen again since it's not only you who's at risk, but also other patients. I'm really worried about what happened, since it's just an easy thing to intervene, but they failed to do so.
