It's a quick one
I got my hands on a saliva antigen test. Not being a fan of nasal swabs, I wanted to see how this one worked. In the box you get the test itself, some reagent in a small bottle, a swab for collecting the sample, and a small bag to spit into.
The process is simple. You spit into the bag, collect a sufficient amount of material with the swab, snap it into the bottle with the reagent, close it, shake it, and wait a minute. Then you prepare the test, break off the top of the bottle, and add three drops. Now you wait — 15 minutes. The test can be read up to 30 minutes after adding the drops. There should always be a line at C; otherwise the test is invalid.
Stay negative!
