False negative results may appear when using AIDS test paper for AIDS testing. If the suspected infected person has doubts about the test results of the test paper, it is best to go to the local CDC for testing. AIDS test paper is divided into three types, saliva test paper, blood test paper and urine test paper. The safety and accuracy of the test paper produced by regular manufacturers are very high, and there are few false negative results, but occasionally accidents may occur, mainly for the following reasons:

1. The test paper is not purchased from regular channels, and the test paper itself is not a qualified inspection product.

2. The test was in the window of AIDS at that time, and the body had not produced enough detectable antibodies, so the result was negative.

Matters needing attention in AIDS test paper

At present, there are three kinds of AIDS test paper on the market, namely blood test paper, saliva test paper and urine test paper. Blood from fingertips or earlobes, exudate from oral mucosa between gums and urine were taken as test samples.

The working temperature of test paper is required to be between 2-30℃, and the normal room temperature is about 20℃. It can work at this temperature. After disassembling the test paper, read the instructions carefully, collect samples according to the instructions, and then find the sample hole on the test paper. After adding the sample into the hole, observe the reaction results within the time specified in the instructions, generally within 20 minutes.
