Serious question: What about the parts and materials needed to make and package the tests (in Maine) - where do those come from, and can they easily get supply of those materials in the needed quantities and quality? What is in them? Guessing, specialty paper, plastic, reagents, probably plastic &/or cardboard packaging... machines to make them if the production line didn't previously exist? If theyr'e all local/regional, it'd be great, but if there's just that one missing component...
