I would presume the answer begs best know evidence on data available in the current AZ testing community

there are way many more bright and highly educated medical professionals who are much better versed than most contributors on this thread - I would be highly skeptical of doing my research from anyone who provides you with answers in this type of forum, including myself

however, if you're truly seeking answers to what you believe is a major flaw in the prescreening or testing of AZ patients in the current medical diagnostic's community, then there are many professionals who you can take this up with outside this thread

when you do, please report back your findings...
