For us, similar to Dr. Lem's company, our traditional business is providing more of a complete test kit where we provide the swabs, the equipment and all of the reagents as well, so we already have a version of this style of test that would also be used for testing surfaces, air, water and sewage, all of the vectors of potential point-to-point contamination for COVID-19 and other pathogenic diseases. The way it would work would be identical to the way it's used for testing people. The only difference is where you take the sample from.
