1. How to check for AIDS
To check whether you are infected with AIDS, it is generally determined by testing the blood of the person being tested for AIDS antigen or antibody. AIDS is a transmissible disease, which is mainly transmitted through the exchange of body fluids with AIDS patients, such as sexual intercourse, injection with the same syringe, or blood collection with the same blood collection needle. If you have such high-risk behavior, you should go to the hospital for relevant antigen and antibody tests after 2, 4, and 6 weeks respectively.
2. How to use AIDS test paper
AIDS test The commonly used paper is HIV1/2 antibody test paper. How to use the HIV antibody test paper is as follows: 1. Open the test paper packaging bag and take out the AIDS test paper; 2. Open the twist cap of the painless blood collection needle and disinfect the middle finger with alcohol; 3. Use the painless blood collection needle between the middle fingers Collect blood by pressing, and after confirming bleeding from your finger, drop two drops of blood into the test paper loading area; 4. Then use a pipette to draw the buffer and drop it into the test paper loading area; 5. Wait for 15 minutes and observe the result.
3. When to test for HIV
The problem of HIV testing is also Regarding the AIDS window period, different testing methods and testing times are also different. Fourth-generation HIV antibodies and antigens can be detected in about three weeks. a normal HIA V-stress test can be performed in about two weeks, and a negative test can be ruled out in about two weeks. HIV testing is highly sensitive and can be ruled out if the test results are all negative within 10 days. HIV is produced after infection and can be detected in the blood.
4. How to detect AIDS self-test
HIV self-test There are many methods. First, you can use the more popular AIDS test strips online. AIDS test strips are divided into blood tests and saliva tests. Blood tests are much more accurate than saliva tests. You can collect fingertip vein blood and drip it onto the AIDS test paper. If the red line shown on the test paper is two bars, AIDS is highly suspected.
5. What method is used for AIDS testing
AIDS There are three detection methods: nucleic acid detection, antigen and antibody detection and antibody detection. Nucleic acid testing is based on the detection of HIVRNA in the blood. HIVRNA can be detected before serological changes occur and is more sensitive than p24 antigen testing. Antigen and antibody testing detects p24 antigen and antibodies. Since p24 antigen appears earlier, about two weeks, the window period is shorter. The window periods for these three methods are 2 weeks, 4 weeks and 6 weeks respectively. If there are high-risk behavioral subjects, you can choose appropriate risk detection methods based on your own circumstances.
6. What are the HIV detection methods
AIDS is mainly in humans The main test item for immunodeficiency virus infection is AIDS antibodies, which are confirmed by drawing blood. Generally, the test is done 21 days after exposure to the virus through high-risk sexual behavior. If the test result is negative, it can basically be ruled out. If the test result is positive, AIDS can be considered. Theoretically, HIV antibody screening has nothing to do with diet.
Okay, this is the end of the article, I hope it can help everyone.
