Thanks for the advice doctor....so is the period of 7 months sufficient to rule out the infection with these HIV 1/2 & P24 antigen test(CMIA) method....and what is the maximum window period for this test.
Brief Answer:
7 months is sufficient
Detailed Answer:
Hello
Thanks for your reply.
7 months is sufficient to rule out HIV infection by the CMIA method. This is known as the 4 th generation test. Usually this test gives accurate information by 4 to 6 weeks after infection. In case some people have delayed response, by 12 weeks after exposure, it's definitely confirmatory to rule out HIV infection.
Hence you do not have HIV infection because the test results are negative.
Take care
