How accurate are HIV test strips?

AIDS test strips are an advanced AIDS antibody detection technology that can detect HIV-1/2 specific antibodies in the blood. The operation time is generally about 10-15 minutes. The operation is simple, fast, accurate, and does not require additional drugs. Therefore, it is very popular among AIDS patients. So how high is the accuracy of AIDS test strips?

HIV test strips types

There are two types of HIV test strips: one is a blood test strip, and the other is an oral test strip (commonly known as a saliva test strip). HIV blood test strips are painlessly collected from the fingertips, usually just one drop of blood is enough. Currently, the best blood test strips recognized on the market are Abbott in the United States, SD in South Korea, and Hangzhou Aibo. There are also many blood test strip brands in China, but due to poor technology, most of them are imitations and are not very reliable; there is only one recognized saliva test strip, namely the American Awei, also known as Aweier, which does not require blood collection, only oral mucosal permeate can be extracted. Because saliva test strips have relatively high technical requirements, domestic technology cannot meet them, so domestically produced saliva test strips are basically imitations. The reagents and detection methods used in the above-mentioned test strips are different. Hospital clinical testing often uses several different brands in combination, and the results are best when they are tested simultaneously and verified with each other. These brands are the most commonly used in general hospitals and CDCs. At present, there are many brands of AIDS test strips in China, but the brands are more diverse, and most of them are produced by small domestic companies, and the reliability is not high. It is recommended that friends must choose test strips produced by regular manufacturers, well-known brands, high reliability, and trustworthy. After all, AIDS testing is related to life, health, and family happiness, and it is not a joke.

HIV test strip accuracy

HIV test strips are an advanced HIV antibody detection technology that is fast, convenient and accurate. Commonly used test strips such as Abbott, Abbott, Aivita, and South Korea SD have a single test accuracy of more than 99.8%. If the test results are the same for two or more times, the test results can be considered 100% accurate. Depending on the characteristics of individual body fluids, HIV test strips generally produce test results in 10-15 minutes, and up to 20 minutes. With the advancement of technology, HIV test strip detection technology has become quite mature, and it can protect the privacy of the test subjects and allow them to know their infection status earlier. It is very popular in hospitals, disease control and a large number of HIV-phobic friends and has been widely used.

At present, the AIDS window period generally follows the six-week theory of the Institute of Clinical Virology of the National Center for Disease Control. This is also the conclusion drawn by the most authoritative AIDS research institution in China after long-term clinical research: the window period is generally 2-6 weeks, starting from the date of high-risk occurrence. HIV can be detected after 2 weeks, and the standard is after 6 weeks. For those who have not been high-risk for 6 weeks, they can start self-testing after 2 weeks to gradually release the pressure. If the test result is negative after 6 weeks, it is completely ruled out. It is recommended to use multiple brands at a time, test at the same time, verify each other, and do AIDS tests at different times to ensure that there is no risk.
