Most likely those are controls for testing the machines for accuracy. In medical facilities it is required to test daily for accuracy. For instance glucose monitoring machines are tested with a positive and negative solution to make sure the machine registers these correctly.

so, what do they use as a testing compound?
Not sure what they use for covid controls. Since it is biohazard I am guessing perhaps a live virus of some kind. For glucometer checks it is a glucose product.
