Slightly tangential to Particulate matter but FDA_TrackerJim reminded me — has the insurance landscape changed recently?

I know it is not exactly on-topic but it seems related enough to ask here rather than starting a new thread. Apologies if this has been covered — I did search first.

Follow-up question: what labs did your doctor order to monitor this

This is exactly right. Dr.EM_Chicago articulated what I have been trying to explain to my friends for months. The Particulate matter aspect is what made the difference for me.
