How much time does it take for syphilis to show up in a blood test?

A doctor has provided 1 answer

Syphilis: Signs/symptoms of Syphilis may occur anytime from 3-90 days after exposure, though usually around 3 weeks. The blood test will likely be positive in this time frame. Many people are infected, however, and have no symptoms at all.
