The different HIV self-tests vary somewhat in their application. Each test kit has detailed step-by-step instructions in the instruction leaflet.
Insti
For the insti, first open the red vial with the number 1. Then disinfect the finger with an alcohol swab and prick the fingertip with the lancet. Drop a large drop of blood into the 1st vial, close and shake well. Pour the liquid into the test field and wait until it has been absorbed. Then add the liquids from the 2nd and 3rd vials, but always wait until the liquid has been completely absorbed. After 5 minutes, you can read the result for 20 minutes.
