Surface fixation as a rapid test for diagnosis of toxoplasmosis.

Surface fixation is a rapid and simple method for the detection of antigen-antibody reactions. It has been used as an epidemiologic and diagnostic criterium for brucellosis, typhus and typhoid fever and recently found to be an encouraging test for amebiasis. Data concerning its application in toxoplasmosis has been considered a justified addition to the more complicated procedures used for the diagnosis of this infection, which has become a world-wide problem. It may thus be used as a screening test, as well as a simplified method of titration of postive sera.
