Sir,what does mean rule out syphilis infection??as you have mentioned in one of the answer...the rule out...is it similar to non reactive??

Your question is not clear. If you provided results in an earlier message and the response was that it rules out syphilis, that meant that you do not have syphilis. It is generally prudent to talk to the doctor who ordered the test. Get HPV vaccine. Wish you good health!

Yes, a non reactive result will rule out the infection. This is where follow up with treating doc remains critical specifically if persisting symptoms as other diagnoses have to be considered and ruled in or out.

To "rule out" means to test for something specific. If you were tested for syphilis and the results were negative, then that issue has been "ruled out". Your issue must be something else.
