title: European interlaboratory comparison of Lyme borreliosis serology.
abstract: Serological testing for Lyme borreliosis was compared in 5 European reference laboratories with a total of 79 sera in order to determine variations in laboratory performance. A considerable range of methods were used and several laboratories employed 2 or 3 genomospecies of Borrelia burgdorferi sensu lato. No laboratory relied routinely on a single test and each weighted the significance of the findings of the various tests differently. A difference in strategy between laboratories in high and low prevalence areas was apparent in that laboratories in low prevalence areas emphasised specificity more than sensitivity and therefore produced fewer false positives, but also missed some cases. Overall agreement between the laboratories was poor and it was concluded that there is a need for a quality assurance scheme within Europe.
