some websites claims 45 and 3 months for conclusive so any necessary to retest at 45 days? if yes. any possibility of this negetive result turn positive after 45 days or 3 months?
There is no realistic chance that your test would be positive. HIV tests are among the most sensitive on the market, for any disease. The only reason to test out to a maximum of 42 days is if you had an exposure with someone who is confirmed to be HIV+. Three months is outdated, and is not recommended by experts in the field.
