Get a retest, I am also married (faithfully), I am a paramedic and I get exposed to blood all the time. Got a needlestick a month ago, got tested for everything and popped positive for RPR (syphillis)
Got retested by the State (as it is reportable) and just got results back today of totally negative RPR and every other test.
Morale of story, get re-tested there are false positives (I am just hoping not many false negatives).
Still have to tell wife why I was depressed for the last few weeks.
It means you have an active syphilis infection. As with all tests, there's a small chance of a false positive, and if you feel like that, you should retest. But please retest ASAP so you can start your treatment.
