P24 and antibody complexing

[Pirlo]

How long is the period that both the antibody and antigen are not detectable in the early course of the infection using a fourth generation test???

[vineet837]

yes , elisa is enogh after 1 year of exposure.

p24 will not work after 1 year of exposure.

[khobar4friends]

U mean Elisa is enogh ?

[khobar4friends]

then teak ...
do u mean after 1 year of the exposure the p24 is not reomanded ?
what kind of test do u recomand after 1 year ?

[Teak]

Correct. MOST people will test positive by six weeks. The three months waiting period is to catch the ones that did not produce enough antibodies at six weeks and by 3 months it is conclusive that if there is no antibodies detected at that time, the person is negative.

[Pirlo]

so if the antibody levels are high enough to be able to make the p24 antigen not detected, they still wont be detected by the test??

[Teak]

P24 is no longer able to be detected when antibody production starts and it can take up to 3 months for there to be enough antibodies for the antibody test to detect. Which is why you have already been told that a conclusive negative test is 3 months.
