1. They don't and haven't since 2004
The manual you provided are from CDC? so this "very rare" statement is done with? Hope so!
Some suggest that immunosuppressed people sometimes have a delayed seroconversion, Dr.HHH says that`s only theoretical.. it`s confusing how science is too vague to provide justification for such a thing.
Can one say to a friend with confidence "you don`t have to retest after your three months - test?"

Dear Teak, Thank you for the answer and manual,I have one last Q regarding this topic, what has "low prevalence" and "high prevalence" -societies?- got to do with the accuracy of a blood test?
I meant ELISA test of course, do false negative results occur more in an HIV low prevalence society? Egypt is considered a low HIV prevalence society, but that`s more according to the "reported cases numbers" and not the reality of things.
What odes this mean for the tests themselves?
Does anyone have an answer? :)
