WebThe traditional algorithm uses a non-treponemal test (NTT) —typically a rapid plasma reagin (RPR) test— to screen sera, followed by one (1) or two (2) TTs on the positive samples. An alternative approach is to use a reverse sequence algorithm, which uses a TT to screen and a quantitative NTT to confirm the positives. Web1.
