The combo test detects antibodies and P24 antigen simultaneously.
The working mechanism of this test is very intelligent, a IV gen antibody test is at it's optimum 28 days post exposure.
Now let's understand how it works - The AB detection of the test is a normal III gen antibody test. For a person who has acquired the virus sero-converts 7-14 days post exposure. 7 days post sero-conversion a normal individual would almost always test positive. Meaning - Should test positive by the next 7 days, the calculation comes to 21 days, factoring in a buffer of 7 more days the total calculation comes to 28 days, hence a negative AB on the 28th day is very encouraging.
Now on the other hand, the AG detection of the test looks for the P24 antigen in the body. For a person who has acquired the virus is sero-converting or has already sero converted however, the detectable amount of antibody has not yet been formed, the P24 antigen has a good chance of being detected. During the formation of detectable amount of antibodies, P24 antigen is present in detectable quantity and once the detectable amount of antibody is formed, the P24 antigen fades away.
Teak has already given you an excellent insight, you don't need testing any more, you have conclusively tested negative.
See your doctor if you are concern. Not HIV related.
Yes Teak i know you stated that i dont need further testing.... becuz of you i go out of my home after so many days... even my mom was worried about me ... though she doesnt know .... she was happy today bcuz i was... and this is what i think my zillions thanks to you will not work...
