I want to ask .. I just read the level of accuracy of the HIV test method CMIA .. Following the statement Antibody tests and antigen tests are used continuously to provide more accurate and early detection results. These tests are rarely used alone because of their low sensitivity and can only work before antibodies to HIV are formed. Is it true that this cmia test is carried out after a window of more than 6 months has a very low sensitivity?

1 Answer:

Good morning, thanks for asking at HealthReplies.com. There are various ways to detect HIV, one of which is the method of Cryuminescent Microparticle Immuno Assay or what is called CMIA. This test has so far gone through various studies and it was stated that this test is quite reliable, accurate and is a standard method of measurement used in many places now. Measured by this method are P24 antibodies and antigens which are the 4th generation HIV tests whose results will be either reactive (HIV positive) or non-reactive (HIV negative).


This test can be done most quickly within 14 days after risk behavior, but if the results are negative, it should be repeated at 12th or 3rd month after risky behavior. This is because there is a so-called window period, where the HIV virus is already in the body, but it still cannot be detected. After 3 months, all viruses should be detected and if the results are negative, it means that there is a high possibility that there is no HIV infection in the body of the person. The accuracy of this test reaches 99.9% in the examination after 3 months.


As for the source you are reading, we try to quote the sentence and the discussion is not specifically talking about the CMIA, nor does it mention a span of 6 months. So we feel that there is a misunderstanding in your understanding when you read, and if you are still in doubt, we suggest you should ask your doctor directly to avoid further misunderstanding. So, hopefully answering your question.
