About BP in a doctor's office, not 1 in 10 of the staff who take BPs does it correctly. Plus, if you see the doc infrequently all he has is a snapshot, when an average would give a better picture, due to the inherent variability of BP. I'm not trained in medicine but I do understand data analysis. The info doctors work from is scary, as is their cavalier attitude toward much of it.
By coincidence, I have an appointment with my retinal specialist today. Awhile ago one of his "techs" said, "Oh, I see your A1C is 8.6". Now I'm borderline diabetic, under good control, and my A1C has never been anywhere near 8.6, hovers around 6.0. Moreover, they are not connected to a data source that would show such a record, would only know what I told them. Then, they routinely ask me "what was your blood glucose this morning?" Damned if I know, I don't have a sticker routine. For some reason they treat me as a full blown diabetic. Like I said, scary.
Where did that A1C number come from?
