I am currently working towards developing a model for type 2 diabetes, using fructose and streptozotocin (STZ). Prior to injecting my C57BL/6 mice with STZ, we tested blood glucose with a tail-prick, using an AccuChek Instant glucometer. As per methods used in relevant literature, I fasted my mice for 4 hours prior to checking blood glucose (BG). The mean BG in my normal control, which did not receive fructose water was around 8 mmol/L, a BG akin to mild hyperglycaemia. Bear in mind, this group is not due for induction, and received a normal diet of commercially available mice pellets. For the second BG test, I fasted my animals for 6 hours, and got the same if not similar results.
Please assist.
