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.

You are probably right there, we had to calibrate glucose monitors and HemoQ machines on our unit daily using High/Low liquid. I'm sure the lab has to do the same with their test reading devices.

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.

Since I am not in possession of these controls and can not say for sure; this is why I said most likely. Based on 50 years as an RN and knowing that machines have to be tested with controls, this is most likely what it is.😉
