If a non diabetic sugar reads 423, 562, HI on a glucose meter what does that mean
Hi I am a 26 year old woman and for a while I have been sweating profusely, craving sweets, thirsty and exhausted. A close friend of mine noticed that all of this and decided to check my sugar it was HI, 562, 351, and 40 what's this mean? I told this to a doctor and they can't find anything? Or when they test it is normal!

My opinion would be that the "stick" was defective, the meter is defective, something else, your friend didn't follow proper protocol. The 423 and 562 are highly abnormal and extremely dangerous.

200 is high. I suspect 423 orf 562 would put you in a coma.

I would be retested by a Physician.
