Scheiner, in his book: Until There is a Cure, The Latest and Greatest in Diabetes Self Care, indicated that ketone testing of urine would be necessary if the blood sugar is high.
Is it a good idea to test if we are not feeling well, even if the blood sugar is between 90 - 180 ("normal"), or is it a waste of time?
Well, it's likely not usually recommended unless BG is ~240. But then again, you have to urinate anyway and the test strips are pretty cheap, so why not.
Trace/small amount of ketones in urine while in a fasting state are actually a healthy and normal state: Ketosis which is completely different from DKA.
Thanks. And what if BG is ~ 240, such as after a meal and if there were a possibility of underdose of insulin (I'm still new to the carbohydrate estimating) Anyone else?
If my BG is persistently high 250 or more I will test my ketone. And if positive or not it's time to get a syringe and take a big revenge bolus. Once I start spilling ketones it takes a massive amount of insulin to get my BG turned around. I buy new strips every year or two, they do not last forever once the bottle is unsealed. If your a T1 you need Ketone Strips.....and it's double important if your a pumper...
