How to self-check whether you have contracted HIV/AIDS

The main methods for self-testing for HIV/AIDS include the following three: 1. Blood testing: Use a specialized HIV test strip and collect a sample of blood from a finger prick or venous blood. Follow the instructions, wait for a certain period, and then observe the result. This method has relatively high accuracy, but proper procedure must be carefully followed. 2. Oral mucosal transudate testing: Use an oral swab to wipe along the upper gum line, place the swab into a diluent solution until fully saturated, then remove and lay the test strip flat to await results. This method is simple and easy to perform, but results may be affected by oral health conditions. 3. Urine testing: After collecting urine, use a dropper to transfer the urine into the sample well of the test card and wait for a period before reading the result. Urine testing is convenient to perform, but results may be influenced by urine concentration and collection methods.
