Carol,

   Was that 400 reading a normal reading for them or perhaps just a spike? It's definitely high but if they had been out having cake or indulging in an ice cream sundae or something equally sweet, I can see how such a reading could happen. Not to worry terribly but to take note of (and to mention to the Dr.). This is NOT true, however, if normal readings are consistently high....as I'm sure you know...and really does need to be addressed ASAP. Some might even say with a trip to the ER.
    I once received a bunch of brand new syringes, strips, lancets and even insulin from a family who lost their diabetic family member. Later we found out that they had had hospice care and it's highly unusual for hospice to allow any type of medication in the house (that belonged to the deceased). Orders are for it to all be thrown away. At the time, I was uninsured and really, REALLY appreciated the extra help.
