Another great find Fred. Great concept but the machines required to read them are quite expensive and I don't think many doctors offices will have them at these prices, hospitals yes. In the long run, this could be a significant development in the world of viral detection if the reading machines can be mass produced to reduce costs. Not only for Covid but for others as well.

I still like our home test with results at what will be a drastically lower cost.
