As I recall BP's company is based on a personalized medicine approach " knowing in advance what medicine to give a patient, what dosage and for how long" were his words to that effect, I believe his company will provide the DX to to do just that for Covid and for many other disease states. Tamoxifen ( breast cancer drug) is a great example of how personalized medicine works. A patient is given a DNA test to see if 2D6 pathway( In the CYP450 system where Tamoxifen is metabolized functions properly). If it does not there is no reason to waste precious time or money on taking that drug. The physician can then choose a different drug to treat patient. Just my opinion.
