I dint do hiv rna test i did only antibody tests,should i need to take RNA test also??recently i kissed 2 girls whose hiv status unknown my mouth was not bleeding and i dont know whethere they have light blood scratch in their mouth (heavily is not bleeding )...i did it unexpectedly though i am suffering from hiv phobia...i read in internet that a person can show hiv positive after 4 , 7years also until then reports could show negative even they have virus in the body.is it possible??some articles in internet showing proofs of patient record to support this ...iam panicked by reading this..please guide me correctly...pls dont hate me treat me as a patient...i regret for i did ,i realised and i dont want to repeat my mistake(i had unprotected sex with a lady once 1.5 year before)please clear my doubt.tnq
