HIV test strips are usually not diagnostic of HIV. Although the accuracy of HIV test strips is relatively high, they are only used as a clinical screening risk assessment, and even if they are positive, accidents cannot be ruled out, and they cannot be used as a basis for a final diagnosis. HIV test strips can be used to quickly screen for HIV infection and can be categorized into urine test strips, saliva test strips and blood test strips. After six weeks of high-risk sex, you can use the test paper to test, relatively speaking, the accuracy is high, even if it is positive, but can not be diagnosed as AIDS. Since there are more HIV test strips available on the market, expired, damaged packaging, moisture, or substandard production batch will affect the final test results and lead to incorrect results. If you suspect that you have AIDS, please go to the hospital or CDC in a timely manner for examination, subject to the results of laboratory tests to avoid delay.
