Um...your doctor may decide to TREAT you as if you were a diabetic,
but if s/he diagnoses you as such and you do not meet the standard
medical criteria established for the disorder, guess what...your
doctor is wrong. Being diagnosed as a diabetic has tremendous
repercussions for acquiring health or life insurance. It isn't
something you want for fun on your records.

MDs do not make up criteria for diagnoses. Although diagnostic
criteria may change over time for specific disorders, they are subject
to standards/diagnostic protocols within their specialty. An MD
doesn't pull the criteria out of her/his hat.

70s, huh? Dead for what reason?

It is used when fasting BGs are inconclusive and other symptoms may be
present, leading the MD to suspect diabetes. It is a standard
diagnostic tool...granted, FBG will likely tell the story, but it
doesn't always...in which case a OGTT will likely tell it...very
commonly used to determine gestational diabetes, too.

It's a pricey test and takes a lot of time for the patient stuck at
the lab, so it isn't requested unless necessary...

Normal blood values for a 75-gram oral glucose tolerance test used to
check for type 2 diabetes:

* Fasting: 60 to 100 mg/dL
* 1 hour: less than 200 mg/dL
* 2 hours: less than 140 mg/dL. Between 140-200 mg/dL is
considered impaired glucose tolerance or pre-diabetes. This group is
at increased risk for developing diabetes. Greater than 200 mg/dL is
diagnostic of diabetes mellitus

Normal blood values for 100-gram oral glucose tolerance test used to
screen for gestational diabetes:

* Fasting: less than 95 mg/dL
* 1 hour: less than 180 mg/dL
* 2 hour: less than 155 mg/dL
* 3 hour: less than 140 mg/dL


Go look on Quest's site for making a lab appointment and the 3 basic
categories for lab work uinder "doctor's orders," you have to chose
one of the following:

For a child under the age of 12
For glucose tolerance testing
Routine

Do you think they'd do that if no one has done them in 30 or more
years?
