After all, the need to account for EVERY single person in the population, therefore they cover persons with even the most REMOTE illness, that could hinder any possible test,...not just HIV
tests. Having contacted 2 ID doctors, they too are in agreement with the views expressed on the Doctor Forum, that nearly 98% of persons show up HIV + by 8 weeks. THey too have never seen an 8 week test turn positive.
But then again...it is up to you.
