After about 68 hours(2013.9.11,12am), I take hiv block drugs from doctor, these drugs are
Tenofovir Disoproxil Fumarate
Tablets , Aluvia (Lopinavir and Ritonavir Tablets) and Lamivudine Tablets. I have take these drugs for 28 days (until 2013.10.8),at 2013.10.9(1 day after taking drugs) , I have take a HIV Duo or Combo (4th generation) test and the result is negative .
so, I want to know
1. Could these drugs delay the hiv window period , so that the combo tese was not correct?
2.
