The latex fixation test (LFT) using Toxoplasma antigen is described. The main parts of this technique are the sensitization of latex particles and incubation of the sensitized particles with sera examined in an icebox (overnight) followed by spinning at 5000 g for 10 min. The sera giving negative results with LFT reacted also in 78.3% with complement-fixing test (CFT) in 79.3% and with indirect fluorescence antibody test (IFAT) in 61.8% and with microprecipitating test (MPT) in 100% negatively. The sera reacting strongly positively with LFT reacted also with CFT in high titers (titer 160 and higher) in 60.9% and in 55% with IFAT (titers 128 and higher).
