Can HIV be dormant for 8 wks aftr unpro expo and not detect Viral Load n Combo Antigen test at 8 wks then active at 9 wks? I knw it can for antibody
HIV) The CDC states that the 4th Antigen and antibody test window period is 18-45 days and the NAT PCR test to be 14 - 33 days. If these tests are taken after the window periods, are they conclusive ? I am confused because some Doctors say 12 weeks?
As per CDC guidelines hiv window period is 6 weeks, is this applicable for both types of hiv 1 & 2 ? as per my understanding 4th generation antigen is only for hiv 1 and only left with antibody which is recommended to test at 3 months?
Again hiv 4th gen test negative at 22 weeks.A doc here said that hiv antibody can take up to 1 year to show up. Is it true ? Anxiety came back
