-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].
- No fasting required. 50g glucose load. Between 24-28 weeks gestation. If FPG >125mg/dL then GDM confirmed. If Peak plasma or 2hr glucose value >200mg/dL then GDM confirmed.
3 True/False questions
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.
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.
Casual (Random) Plasma Glucose (RPG) Assay → Fast for at least 8hrs. FPG result less than 110 mg/dL is normal, between 110 and 125 mg/dL imply impaired fasting glucose (IFG), values greater than or equal to 126 mg/dL indicate DM.
