Hi sir,I have unprotected sex with prostitute on September 2015. I have done tridot test on Jan 2016,may 2016 and western blot test on June 2016. All the results were negative. But I have taken antitubercular medication(due to cervical and mediasternal lymphadenitis and bone tuberculosis) i.e. rifampicin, isoniazid,pyrizinamide and ethambutol during the HIV tests.Does these medications will give false negative during tridot and western blot testing? Shall I go for other confirmatory tests? Recently I got eosinophilia and last 6 months ( Oct 2016 to April 2017) my tongue becomes dry and white in colour (initially tongue becomes orange colour in mornings and now it becomes white and dry on morning ) kindly advice me. Thank s in advance.
