Rapid test for diagnosis of syphilis by means of the surface fixation method using as antigens VDRL and Treponema pallidum (strain Nichols).

An attempt to use the "surface fixation" method for the detection of antigen-antibody reactions with VDRL and Treponema pallidum has given results which corroborate conventional serological findings in patients suspected of being infected with this organism. The test is performed over strips of filter paper in which mixtures of the serum with the antigen are deposited and submitted to a special procedure of staining in order to detect antigen-antibody reactions.
