RE:Test coming to Ontario jan 4. If Ichor Blood Services sells saliva based tests and talks to Air Canada, this could become a serious competitor for DM in respect to the business with AC.
BUT as long as the regulators like CDC, WHO, and other regulators, see in RT-PCR the gold standard, there will be no relevant competing product. Because for internationl acceptance of testing results it need regulated worldwide used testing procedures, and this is RT-PCR.
