Hi doctor,
Please suggest how far is CMIA test for HIV is conclusive at six months. Some say that three months are sufficient enough and a few say that six months is conclusive for 98 % cases. Which is the truth? Which is the category who take more than three months for seroconversion?
Hi,
Welcome to icliniq.com.
CMIA(chemiluminescent microparticle immunoassay) also know as the HIV-DUO test. It checks for two things, both antigens and antibodies. So, this test is highly conclusive after six weeks, and at six months, it is very conclusive. Seroconversion means developing antibodies against the virus. HIV-DUO detect antibody, but it also recognizes an antigen as I said. So, CMIA will come positive even if antibodies has not yet developed. Antibody may take time to develop (means seroconversion) in those with weak health or having cancer or taking chemotherapeutic drugs. These people are not able to produce antibody early, so it is not detected. But, they get antigens when they are infected, and HIV-DUO or CMIA tests can detect it. So, this test is highly conclusive.
