title: Quality control in diagnostic virology.
abstract: Quality control in diagnostic virology is in its infancy and some preliminary investigations are reported. Simulated specimens containing viruses have been prepared and distributed so that they could be included in the routine work of virus isolation in participating laboratories. Sera containing antibodies to rubella and influenza virus have also been sent to laboratories for testing. Laboratories were able to check their results immediately after the closing date, and could compare their performance with that of other laboratories when the analysis of each distribution was circulated. The results so far show considerable variation in performance and indicate that there is room for improvement in some laboratories. There is no evidence to show whether the exercise has had any effect on the practice of virology in participating laboratories but some baselines have been produced for comparison with the results of investigations in the future.
