Hi
Thanks for writing here.
I have gone through your query, it is common to have positive TPHA after treatment
You need not to worry if you have complete the course of penicillin injection .
False positive results are seen in many patients with Treponema pallidum haemagglutination test. Certain patients were leprosy also showed false positive TPHA. For confirmation i would have asked you to do DARK ILLUMINATION TEST .
Hope this helps.
