15 Questions
What is the purpose of the fasting plasma glucose test?
To screen for diabetes mellitus and other disorders of glucose metabolism
How does glucagon affect plasma glucose levels in the fasting state?
It raises plasma glucose by accelerating glycogenolysis, stimulating gluconeogenesis, and inhibiting glycogen synthesis

70-100mg/dl (3.9 – 5.6mmol/L)
At what fasting blood glucose level is diabetes mellitus considered diagnostic?
140 – 150mg/dL (7.8-8.3 mmol/L)
What do nonfasting blood glucose levels exceeding 200mg/dL (11.1mmol/L) suggest?
Diabetes
What is the primary purpose of the fasting plasma glucose test?
To screen for diabetes mellitus and other disorders of glucose metabolism
What is the role of insulin in regulating blood glucose levels?
To check the rise in glucose levels by promoting its uptake into cells
