How soon does syphilis show up in a blood test?there are diff names for certain tests, does it matter what test?do they detect all in same time frame?

Syphilis: Usually within the first six weeks after a possible exposure. Syphilis is unique in that when one is infected in their mouth, vagina or rectum they may miss the first stage of syphilis because the sore it causes does not hurt. If one has an unexplained sore in this scenario then testing definitely should happen. But, in general six weeks.
