HIV self-testing
HIV self-testing, HIV is a chronic virus, sometimes it may be short-lived, or simply there is a problem with the sampling at the time of the test, resulting in inaccurate results. Here's a look at what HIV self-testing methods are available
HIV self-testing 1What are the HIV self-testing methods?
1, test paper test
Want to self-test AIDS, you can go to the regular institutions or drugstores to buy AIDS test paper. If the body is already infected with HIV, the body will produce antibodies, and through the test paper, you can find out whether you are infected with HIV. This is a popular and quick method of self-testing, and you can find out whether or not you are infected with HIV through the results of the test. If you have AIDS, you need to take immediate treatment to prevent the disease from worsening and causing health problems.
2, medical equipment testing
Want to self-test AIDS, you can use some medical equipment or machine self-test, to see whether their bodies have produced HIV antibodies. Generally through the method of immunization can automatically detect whether the body produces antibodies, its operation is simple, and widely used.
If you have a small space, you can even test yourself at home, so if you want to test yourself for HIV, you can do it with a medical device. A full set of equipment is purchased and placed in the home, and when AIDS is suspected, the machine is utilized to test and obtain accurate results. Once the diagnosis of HIV is confirmed, treatment needs to be taken immediately to improve the condition through antiretroviral therapy.
3, combined with the clinical symptoms of judgment
AIDS self-testing method is actually relatively small, there is another self-testing method is more suitable, that is, a combination of clinical symptoms of AIDS to judge. During the development of AIDS, the more obvious symptom of the patient is the body fever, and easy to have lymph node swelling, weight loss of the obvious performance. Early on, there may be muscle pain, gastrointestinal discomfort, and with the development of the disease, there may be neurological symptoms, respiratory symptoms.
Noticing that you have these abnormal signals, you need to pay attention to it, it is likely to be caused by AIDS. The virus attacks the human lymphocytes in the body, causing damage to the immune system, which is what causes these symptoms. This is also an effective way of self-testing for HIV, by which you can usually find out if you are infected with the virus.
HIV self-testing 2Ten self-tests for HIV
The first step: look at the HIV test paper
For your convenience, the HIV test paper is mounted in a plastic card holder, which makes it more convenient to use, and the principle of the test is unchanged, which is still the double-antigen sandwich The principle of the test remains the same, it is still a double antigen sandwich method.
The description of each part is as follows: the small round hole (S area) is the sampling hole, the tested blood drop should be dropped into the hole. The long, narrow depression is the result area, where T is the position of the test line and C is the `position of the control line.
Step 2: Blood collection
Blood collection instruments: blood collection needle (medium thickness sewing needle can also be), alcohol, cotton balls.
Blood collection site: fingertip or earlobe. Blood collection method: first use alcohol cotton balls to disinfect the blood collection site and blood collection needle, and then collect the preparation.
Note: The first drop of blood should be discarded and the second and third drops should be used for the test. Drops of blood should be placed directly into the sampling hole, or sucked into a clean pipette first, and then dropped into the sampling hole.
Step 3: Interpretation of results
Observe the results within 10-15 minutes after sampling.
1, only one red line appears on the test paper (control line C) for negative results;
2, two red lines appear on the test paper, (control line C and detection line T) for positive results;
3, the test paper does not appear on the red line, indicating that the test experiment has failed, please take another card to re-test.
It is important to note that since there are always "false positives" in any test, don't be nervous if you get a positive result, but go to your local CDC to confirm, or ask us for advice, which is of course confidential. For negative results, if you test negative after the "window period", you can rest assured that you are not infected with HIV.

AIDS latency symptoms When it comes to AIDS, I believe everyone knows. How many of you know the symptoms of HIV incubation period? If you don't know, then let's take a look below. 1, systemic symptoms Clinical symptoms in patients with AIDS are commonly recurring low-grade fever (about 72%), accompanied by chills, lethargy, fatigue, weakness, and weight loss (up to 5-22 kilograms), followed by extreme lethargy and weakness, and can not support the usual physical activities. In the case of diarrhea, we need to pay attention to the chronic diarrhea is also a very obvious early clinical manifestation of some AIDS patients. And often can not find the cause of fever, diarrhea and weight loss. According to the characterization of the clinical manifestations of 38 cases of AIDS, these symptoms and signs accounted for more than 80% of the total number of cases. 2, lymph node swelling The incidence of 55% to 100%, when the high-risk group of patients with generalized lymph node swelling and can not be explained by other reasons, is likely to be related to HIV infection. The enlarged lymph nodes, although generalized, are most often found in the posterior neck, submandibular, or axillary lymph nodes. The enlarged lymph nodes are non-fusing, hard, occasionally painful with no surface skin changes. The degree of lymph node enlargement correlates with the level of HIV antibody in the serum. In addition, lymph node enlargement may also occur in AIDS-associated lymphomas, including Burkitts lymphoma, immunoblastic lymphoma, and Hodgkin's disease. 3, skin damage The skin and mucous membranes are one of the main invasive parts of the HIV, so AIDS patients often water symptoms of skin damage, and usually have a rash, itching, and urticaria disease. However, the skin damage is characterized by the skin changes of Kaposi's sarcoma, which will be described in a later section and will not be discussed here.

HIV self-testing 3 If you suspect you have AIDS and don't want to go to the hospital for a checkup, what should you do? To avoid embarrassment, I'll share two HIV self-testing methods. The first is the blood test paper test. It is done by puncturing a bit of skin with a blood needle to get a blood sample. The first drop of blood is usually not suitable for this test, and the second or third drop of blood is used. The sample is taken from the tip of the finger, and the results appear within 15-40 minutes. The second is the saliva test. This saliva test uses saliva directly from the gums as the test object, and the advantage is that there is no need to collect blood, so there is no pain. It also greatly protects the privacy of the patient and is very easy to operate. But because HIV antibodies in saliva are still rare, the accuracy of this test is relatively high, reaching more than 90 percent. It's also recommended that when testing with HIV test strips that you do it several times, with the testing cycles spaced out. This is because HIV is a chronic virus, and sometimes the disease may be short-lived, or there may simply be a problem with the sampling during the test, resulting in inaccurate results. So if you choose to test yourself, it's recommended that you do it more than once. Although nowadays there are very convenient test strips that allow people to perform self-tests. But it is important to emphasize that the purpose of the test is to find out how you are doing. Even if it is 99 percent correct, there is no guarantee that you are not the one percent.
