My post 5622 was not intended to be as a negative for nnlx. It was to show the fixation of the FDA on PCR and the limitation based on the availability of the equiptment necessary to complete the test. Why no one in the media doesn't ask the question, Can PCR distinguish between alive and dead virus? What are the alternatives? As wondefrful as PCR maybe, it alone is not the end all for all the worlds health care detection needs.
