Definition
-ears, lip margin, or foot pads
Term
What is fructosamine?
Definition
-glycated proteins (primarily albumin) that have irreversible binding of glucose
Term
What does an elevation in fructosamine indicate? What action does it indicate?
Definition
-indicates poor glycemic control
-need to perform glucose curve: will not differentiate b/n insulin under dose, short duration, and somogyi
Term

Definition
-Continuous glucose monitoring system
-measures interstital glucose every 5 min up to 72 hours
Term
Can we use urine glucose strips as a stand alone test? HOw do we use them? What do they indicate?

-no
-multiple times in same day once weekly
-if always glucosuria = poor control & if never glucosuria = may be overdosed
Term
Describe long-term canine DM management if no clinical signs?
