3 Multiple choice questions
-Impaired Glucose Tolerance (IGT). Glucose level rises higher than 140 but is less than 200.
-Impaired Fasting Glucose (IFG).
- Performed in place of OGTT (Oral Glucose Tolerance Test). For patients w/ poor absorption of orally administered glucose. [May have a glucose transporter problem in GI tract].
- Plasma glucose measured 2hrs after 75g glucose load. Value greater than or equal to 200mg/dL indicative of DM if confirmed on another day by either an elevated FPG (above 126) or RPG value (200) or elevated glycosylated hemoglobin A1c.
3 True/False questions
Oral Glucose Tolerance Test (OGTT) → Plasma glucose levels measured every 30mins for up to 3hrs. In diabetic, glucose levels start high and rise higher than in a normal patient. Levels also remain higher for a longer period of time.
What are normal FPG and 2hr Postprandial after 75g glucose challenge? → - FPG below 110 mg/dL
- 2h PG below 140 mg/dL
Borderline type includes those who are neither diabetic nor normal types, e.g. IFG or IGT.
Fasting Plasma Glucose (FPG) Assay → Irrespective of last meal or time of day. Glucose result of 200mg/dL or greater in presence of symptoms is presumptive of DM.
