there’s a tube that should have liquid in it. If it’s not in the tube already, it’s in the box for you to put in the tube. After that, take the nasal swab and swab your nostrils. Put swab in tube w/liquid and swirl it around for 10 secs. Leave swab in tube for a minute, and when you remove it, squeeze the tube around the swab to get out all liquid soaked into tube. In kit there should be a dropper attachment for tube. Attach and squirt three drops of tube sample into the oval marked with S on test kit. Wait ten minutes for result (usually shows up after a min).
