There are three separate tests done for syphilis with your blood sample. Sometimes, a syphilis test can react to something in your system that is from a different infection or condition.


Sometimes, one (or two) tests can show a Positive result, while the other tests are Negative, or Non- Reactive. You will be asked to repeat the blood test in two weeks if this happens. If the result remained the same after the repeat test, it would be considered a False Positive result.
