Ask for a syphilis blood test from a clinic, doctor, or sexual health center
Ask for repeat testing if exposure was recent, since early infection may not show up right away
Seek urgent medical care if you have vision changes, hearing changes, severe headache, confusion, or trouble walking
Do not rely on symptoms alone, since syphilis can have no symptoms
Avoid sex until you have been tested and treated if needed
Tell recent sexual partners if you test positive so they can be tested too
