The window period of AIDS is the time from HIV infection to HIV antibody production in the body, which is called the window period. How long is the window period of AIDS? How long does it take for AIDS antibody to be negative?
What is the window period of AIDS
First of all, we need to explain the concept that we do blood testing, which is blood test. This test is the AIDS virus antibody in the blood. If you check the AIDS virus antibody in the blood, it means that you are a AIDS virus infected person, and you have AIDS virus in your body.
However, it takes time from the entry of AIDS virus into the body to the occurrence of antibodies, which is generally 3 weeks to 2 months, and cannot be found before the occurrence of antibodies. The possibility of detecting HIV antibody is very low, but there is virus in the body and virus in the body, but what the antibody cannot detect is the window period.
In short, the AIDS window period is the period from AIDS virus infection to AIDS virus antibody production in the body, which is called the window period. After the human body is infected with HIV, it usually takes 2 to 12 weeks, with an average of about 42 days before HIV antibodies can be detected in the blood. The time from infection with HIV to the production of antibodies by the body without detecting HIV antibodies is called the window period. During the window period, HIV antibodies cannot be tested, but due to the presence of HIV in the body, there is also contagiousness during the window period.
Why did you mention the window period? Because in the window, people infected with AIDS can transmit the virus to others. If the first test is negative, the doctor usually recommends another test after two to three months to confirm the result. If it is found to be negative after three months, you can almost rest assured. Because few people have a window period exceeding 3 months.
How can AIDS test paper be accurate
The accuracy rate of AIDS test paper is reliable, the accuracy rate of saliva AIDS test paper is 99.85%, and the accuracy rate of blood AIDS test paper is 99.7%, all of which use the same reagents as hospitals, CDC, blood stations and other medical institutions.
Detection principle of AIDS test paper: AIDS test paper is a next-generation detection reagent developed by colloidal gold immunolayer analysis technology, which can detect HIV-1/2 specific antibodies in serum and plasma samples. Through the joint evaluation of the China Institute for the Control of Pharmaceutical and Biological Products, six authoritative AIDS monitoring centers in China, validation laboratories, blood centers and hospitals, the results show that the sensitivity of this test paper reaches 99.40%, the specificity reaches 100%, and the total compliance rate reaches 99.7%. The quality of AIDS test paper is the same as the current international mainstream reagents.
