Results of serological tests for syphilis performed on donors and patients at the Institute of Haematology over the last two years are summarized. The results of tests performed by cardiolipins ++ USR and VDRL antigens, and later confirmed using FTA-ABS and TPHA methods were evaluated. They indicate that the recently produced USR antigen is more sensitive and more specific than VDRL antigen. Similarly, TPHA proves to be more sensitive than FTA-ABS test in these prophylactic assays.
