The appearance of 2 bars after 2 hours of HIV test paper does not have much reference value or special significance.
The HIV test paper is divided into the quality control area and the detection area, the appearance of two bars means that there is a bar in each of the two areas, indicating that the initial screening is positive, suggesting that may be infected with HIV.
However, it takes 15 to 20 minutes to determine the validity of the HIV test results, and if the two bars appear after 2 hours, the results are not accurate and of little significance.
The presence of two bars after 2 hours is considered to be a false positive due to oxidation or reaction with other substances, and it is recommended to go to the hospital for examination.
It is important to note that the results of the HIV test cannot be used as a basis for diagnosis or exclusion of HIV. If you suspect HIV infection, it is recommended that you go to a regular hospital or CDC for testing.
