[Determination of arenavirus antigens and antibodies by solid-phase radioimmunological analysis]

The necessary conditions of solid-phase radioimmunoassay (SPRIA) have been developed for the detection of arenavirus antigens (Junin, Machupo, Tacaribe, Amapari, and LCM). The sensitivity of SPRIA is higher than that of the complement fixation test more than 100-fold. The antigens could be detected by this method in various materials.
