Number of patients who would have been diagnosed as having syphilis, being BFP, or being false negative based only on nontreponemal and treponemal test results
Test No. of patients with the indicated result in the following test: RPR NR (missed)d RGNa NR (missed) R R Syphilisb BFPc Syphilis BFP MHA-TP 242 27 12 251 33 3 TP-PA 242 27 15 250 34 7 Syphilis-G 242 27 15 252 31 5 ↵a RGN, Reagin II test.
↵b Diagnosed as having syphilis based on reactive nontreponemal and treponemal test results.
↵c Diagnosed as BFP based on reactive nontreponemal test result and nonreactive treponemal test result.
↵d Diagnosed as not having syphilis based on nonreactive nontreponemal test, but the treponemal test was reactive, indicating either past or present syphilis.
