The supply and use of blood during war or disaster require efficient cooperation between national and regional civilian authorities and blood banks as well as the military chain of command and medical units. Tasks and responsibilities are regulated by a directive issued by the Norwegian Armed Forces Joint Medical Services, specifying that during crises, civilian blood banks will be ordered to provide blood to military units. Based upon information obtained by a questionnaire survey, blood banks have an adequate capacity even if the normal power supply or computerised systems fail temporarily. However, plans are presently lacking for the organisation and operation of the civilian blood supply during a crisis requiring cooperation with military units. Key roles and responsibilities for personnel on the civilian side must be defined. Normal and alternative routes of communication must be established and tested regularly.
We modify Dorfman's and Sterrett's group testing protocols to make them suitable for testing blood samples for the presence of HIV antibodies, as well as for many industrial applications, when false negatives cannot be tolerated. We first propose that test kit sensitivity be increased to nearly 100 per cent by altering the reactive versus non-reactive threshold. Subsequently, group and repeat testing are used with a careful selection of group size and the number of times a test is repeated, in order to maximize efficiency while keeping the false positive predictive value (FPPV) within a specified limit. Numerical calculations show that our testing protocol is efficient, has low procedural complexity and keeps both types of classification errors below specified tolerance limits.
