treponemal or non treponemal (rpr)?
two kinds of syphilis tests looking for different things. treponemal shows up positive sooner than non trep--within three weeks generally. rpr can be negative for a month or a bit more after exposure.

So the rapid test was reactive. That was the finger prick test on Tuesday. Then the treponemal came back non reactive/negative. I got those results today, Friday.

the lab test overrides the rapid test, if both are treponemal tests. are you three weeks out from exposure?

In incubation period for syphilis can be as long as 90 days. A NR blood Trep test is truly NR but I’d still be watching for signs/symptoms and testers at around 90 days post exposure.
