How to detect antibodies? Expectant mothers must take action

Antibody testing includes many contents, among which HIV antibody testing is a project that all expectant mothers must test during pregnancy. It is the so-called AIDS. This disease is very harmful and can be transmitted to the fetus through the placenta. Therefore, if expectant mothers find that they have any discomfort in this regard, they must actively test and treat it.

1. How to do HIV antibody test

How to test HIV antibodies? There are generally two methods for testing HIV antibodies. One is the enzyme-linked method, which focuses on allowing antibodies to bind to enzyme complexes and then detecting them through color development. The second method is the rapid method, also called the "gold standard method", in which the test results can be obtained in a short time using only a special test strip. The detection method used in our country is Western blotting test (WB). There are three possible results for HIV antibody testing: negative, positive, and indeterminate. If the normal value of the HIV antibody test is 0-1, it is negative within this range. If it exceeds 1, it is positive and further examination is required.

2. Purpose of HIV antibody testing

HIV testing during pregnancy is to provide a basis for early prevention and treatment for pregnant women, thereby improving the quality of life of pregnant women and improving the health level of children. Mother-to-child transmission is one of the three main routes of HIV transmission. The HIV virus can be transmitted to the fetus through the placenta, causing the newborn to be infected with the HIV virus. The purpose of HIV antibody testing is to confirm the reaction of the pregnant woman in early pregnancy and to check whether the pregnant woman herself is carrying or has been infected. Through pre-pregnancy examinations, doctors can provide adequate treatment to pregnant women during delivery.

3. How to read HIV test report

Pregnant mothers have the HIV antibody test during prenatal checkups. The purpose of testing HIV antibodies is to reconfirm the pregnant woman's reaction during early pregnancy and to check whether the pregnant woman herself is carrying or has been infected. I believe everyone is wondering what the various complex data on the test report mean. Here I will teach you how to easily read the HIV test report.

There are four methods for detecting HIV: Western blot (WB), strip immunoassay (LIATEK HIVⅢ), radioimmunoprecipitation assay (RIPA) and immunofluorescence assay (IFA). The detection method used in our country is Western blotting test (WB). There are three possible results for HIV antibody testing: negative, positive, and indeterminate. If the normal value of the HIV antibody test is 0-1, it is negative within this range. If it exceeds 1, it is positive and further examination is required.

IV. HIV Testing Prices

I believe mothers must be very concerned about the price of the test. The price of HIV antibody testing corresponds to its testing method, and the price is between 100 and 180 yuan. HIV virus can be identified by detecting viral antibodies, antigens, nucleic acids or virus culture. Currently, the standard testing method is serological HIV antibody testing, which is not very expensive.

For pregnant women who highly suspect that they have been infected with HIV and are anxious for the results, a viral load test can be performed. This test method can be used as an auxiliary diagnosis for those in the early stages of infection whose antibody test results are uncertain or antibody-negative. The cost of this type of AIDS test is relatively high.
