Thank you for this valuable service. For syphillis what is the testing window always six weeks or is it different if there are or are not symptoms? If there are symptoms is the testing window a few days after, a week after or six weeks after? Thank you

When person who has acquired syphilis develop primary, ulcerative lesions at a site of inoculation, blood test for syphilis become positive within 2 to 4 days following the appearance of the lesion, irrespective of when or where the lesion appeared.  Other signs of later stages of syphilis such as a rash or swollen lymph glands are always accompanied with positive blood test at the time they appear or are detected.

Not all persons who acquire syphilis however are aware of developing signs or symptoms of infection which lead them to seek care. In this circumstance, persons who may have been exposed to a sexual partner with Syphilis will have definitive test results six weeks following their last encounter. Blood tests that are negative for syphilis infection at any time more than six weeks following a potential encounter in which syphilis may have been acquired are conclusively negative and there is not a need for further testing.

I hope this information is helpful. EWH

Is Syphillis passed via bodily fluids or strictly through direct contact with a sore? Also how is it transmitted in later stages? Thank you again for the information that you provide on this site. Have a nice day.
