Can A Certified MD Order A TPPA Confirmatory Syphilis Test That Has Turned Up Negative?
Thank you, XXXXXXX
Thanks for posting the query.
I read your problem. Any doctor can ask for some test on the basis of clinical suspicion. If the laboratory refuses to do the test it is purely a local problem and the concerned doctor has to convince the lab or find some other lab.
Doing the test in another country is difficult as it involves restriction in transporting blood samples. Hence I am helpless in this regard. RPR (Rapid Plasma Reagin) may show both false positive and false negative results. RPR is only a non specific test for syphilis. However, if they do VDRL (Venereal Disease Research Laboratory) test that may be more useful.
Hope I have answered your query. Please accept my answer in case you do not have further queries.
