How Long Does Syphilis Take To Resolve Post Antibiotic Treatment?
The cause for Biological false positive has to be identified.
Welcome to HCM.
Thanks for posting your query.
VDRL reactive, but TPHA nonreactive means you are not having Syphilis. It is called as Biological False Positive. BFP will be less than 8 dilutions. It can occur in the presence of diseases other than Syphilis.
Two types of BFP:
1 Acute BFP-- Positive less than 6 months
2. Chronic BFP--- Positive more than 6 months (sometimes for years).
Try to identify the underlying diseases (with investigations) and treating the same will help you to get a VDRL nonreactive.
Azithromycin 4 days can not be the solution for BFP. Consult another experienced physician or who is an expert in STD management.
what is the proper treatment for this.
and after the treatment, when can i do the test again to check the result will be positive or negative?
No treatment is necessary at present
Once again check TPHA test in some other reputed laboratory. If that also nonreactive, you need no treatment for Syphilis. In that case, try to fix the cause for biological false positive result with investigations. Your physician will guide you for the same. If no cause is found, ignore the RPR reactive report. Repeat the test after 6 months. Treatment has to be considered as per the outcome of the investigation reports. Consult your physician or Dermato-venereologist.
