Holy crxp
@Cumberland,
That was indeed a high one there! ;o)
Happy you are still with us. Cant recall myself what my own highest might have been, as it was probably back when I was admitted to the hospital the very first time at point of diagnosis? Can recall some of the highest readings I had when I back in the 80ties got switched on to that new amazing rocket science stuff called fast acting insulin and a near-instant bg meter: The meter showed 26 mmol/L and the caring staff clapped their hands and encouragingly expressed: "Wow - not bad at all!"
But clearly not a number to brag too much about as life can indeed become complicated or over all together.
Just looked up "the human medical records" and found the highest ever recorded bg in a human being and surviving it was:
Mr. Michael Patrick Buonocore from the USA, a 7 yo kid who was admitted to the Pocono Emergency Room in Pennsylvania, on 23 March 2008 with a
blood sugar level of 147.6 mmol/L. Converting that to a
HgAc1 would give you around 85%. Though do recognize you cant just freely convert like that, as the HgAc1 express a sustained average at that very number, which of course most probably is not what that young kid had been through before ending up in the emergency room.
