AIDS testing is an effective way to prevent AIDS. For women who are ready to become pregnant and those who have too many sexual behaviors, AIDS testing is more necessary. Let's go to see who needs AIDS testing.
Five categories of people need to be tested for AIDS
1. As we all know, unsafe sex is one of the main ways to spread AIDS. If your sexual behavior is rampant, whether men, women, old or young, regular AIDS testing is necessary.
2. Blood donation or blood transfusion, we all know that paid blood donation and blood transfusion have the risk of AIDS infection, and AIDS testing should be done afterwards. But prevention is more important than testing. When donating and transfusing blood, do not use shared needles or other devices.
3. For pregnant women, mother to child transmission is one of the ways of HIV transmission. Pre pregnancy testing can help you decide whether to prepare for a baby; Prenatal testing can provide more protection for the baby.
4. Injecting drugs and sharing needles, injection, acupuncture, especially injecting drugs and sharing needles, all pose a risk of HIV infection. In addition to conducting testing, it is more important to avoid injecting drugs and sharing needles.
5. If you are infected with a sexually transmitted disease and test positive for it, then it is a dangerous signal, and the biggest risk is not from sexually transmitted diseases. But you may be infected with the more terrible virus - AIDS. Timely detection and diagnosis can help you get rid of AIDS or take active measures to treat it.
What are the methods of AIDS testing
1. Antibody testing
There are mainly enzyme-linked immunosorbent assay (ELISA) and immunofluorescence assay (IFA), rapid detection method, also known as gold labeling method, which is also a method of antibody detection. According to the principle of immunochromatography, it is used for qualitative detection of HIV antibody detection.
2. Antigen detection
Using ELISA to detect P24 antigen, the antigen is present in the blood before antibodies appear in the early stages of HIV infection. Due to the low amount of P24, the positive rate is usually low. Currently, dissociation immune complex method or concentration of P24 antigen are used to improve sensitivity.
3. Nucleic acid test
The PCR method for detecting HIV genes has the advantages of being fast, efficient, sensitive, and specific. At present, this method has been applied to the early diagnosis of HIV infection and the study of AIDS.
