What Is The Accuracy Of A 4th Generation HIV Test?
Question: all laboratories with detecting system antigen p24 and antibodies are the same window period of on this Ag/Ab this they applying just for 6weeks
Brief Answer:
You are free from HIV 1 infection and and also HIV 2
Detailed Answer:
Hi,
Welcome to HCM.
Thanks for posting your query.
You had mentioned about the 4th generation DUO test, I think. This test comprises of two parts.
1. Antigen detecting part as P24 antigen of HIV 1 infection
2. Detection of antibodies against both HIV 1 and 2.
P24 antigen can be detected as early one week after the entry of organism and considered conclusive by 4 weeks after the exposure.
Antibody against HIV infection appear inside the body in the presence of infection only after the completion of window period.
Window period for HIV infection is around 6-8 weeks, may be extended in some individuals up to 12 weeks. So this part can be considered as conclusive only after 12 weeks after the risk activity.
The nonreactive or a negative 4th generation HIV test after 10 weeks ruled out the possibility of HIV 1 infection beyond any doubt and the HIV 2 to the extent of almost nil.

HIV and STD organisms are highly fragile. They can not withstand very weak antiseptics or heat.
The chemicals and its composition can be lethal to HIV. Then its contact is enough to kill the virus.
