> Get a test before you start, so you have a base value. Test again after a month or two maybe three, and see what the change is. This is sound advice, but isn't there a chicken and egg problem right now? We're in a significant part of the pandemic, which I would imagine (assumption) that "routine" tests such as that may not be easy to come by. While at the same time there is notable evidence that VDI is prevalent in severe cases. By the time you get an answer to know the base line, it seems like it would be largely too late to make a possible difference in the short term? Is there a "safe" amount you could increase it without knowing your base line?
