ANTI M. leprae IgM ANTIBODY DETERMINATION BY ULTRAMICROIMMUNOENZYMATIC (UMELISA HANSEN) FOR THE DIAGNOSIS AND MONITORING LEPROSY

The relationship between the IgM antibody response, antigenic load as well as the clinical improvement after chemotherapy was studied in order to obtain useful data for the early diagnosis and monitoring leprosy. A level of 82% (94/115) agreement was obtained between IgM UMELISA HANSEN and slitskin...
