Yes not cheap and slow turn around time but a step. If you believe, as I do, the adaptability of the N Assay (b) to a N Assay (v) someone has to be considering, testing and preparing to commercially develop the (v) for mass distribution once approved by the FDA. Of course everything is dependent on FDA approval. Other countries have less strict requirements as can be seen by the number of tests already out there although results are not reliable.
