An evaluation of Richardson's verification test in the sero-diagnosis of syphilis

Abstract

The importance of the accuracy of serological tests for syphilis has become more than ever emphasized by widespread testing and more efficient therapy. The problems are reviewed in the light of present knowledge of the specificity and sensitivity of standard serological tests for syphilis. Richardson's modification of the Wassermann reaction is described. The results of this test when applied to ninety-two cases giving doubtful or discrepant reactions by routine tests are presented and classified. The cases were followed up clinically. The results indicate that this simple test is a reliable and valuable adjunct to routine methods, and should be employed widely as a verification procedure.
