Thanks for the many replies so far and in
general,laboratories quote (as we do)11.1mmol/L as the upper
limit of "normal" for a random plasma glucose.Unless I am
mistaken,this goes back to the dark days of GTTs in Varley
1st edition etc when 200mg/dL was the "normal" maximum (?
whole blood) glucose level 30 minutes post glucose
load.Therefore a "normal" person is "allowed" to have a
random glucose value up to this level and of course 200mg/dL
equates to 11.1 mmol/L,
How many people have meals at any time equivalent to 75g
glucose and how many of you out there would like at any time
to have a plasma glucose of 9.1mmol/L let alone 11.1 mmol/L.
I understand the sentiments in Jonathan's e-mail but if we
cannot know what question is being asked,how can we know what
answer to give?
With regard to Richard's comments.I am not sure if it is
exactly the same problem as in the GTT thread before
Christmas.He says results should reflect disease but if we
tell GPs that its "normal" to have a random glucose up to
11.1 mmol/L then its not reflecting anything.
