Tu analyze & cgm

How can Tu Analyze report 16% report a health problem with cgm? WHAT does THAT mean? cgm does not give a health problem.

They are doing surveys asking for these problems. If a cgms is sometimes reporting numbers way lower than the reality it is a health issue. I would have taken a correction instead. In my last use the cgms was pretty blind for numbers above 200. If a cgms does not catch a low at night it is a health issue too - not caused by the device of course. But it was expected that this type of event can be detected at least earlier. Problems in accuracy can also lead to stress, anxiety and worries. In general I found the cgms useful but the issues do exist.
