Q
how to screen?
A
A- One step approach:
75g 2H oral gluc tolerance test,criteria:
-Fasting plasma glucose ≥92 mg/dL but <126 mg/dL
-1H ≥180 mg/dL
-2H ≥153 mg/dL).
B- Two step approach: 1H plasma glucose after 50g oral gluc ≥130 mg/dL go to 100g 2H oral gluc tolerance test. -Fasting : 95 mg% -1h : 180 mg% -2h: 155 mg% -3h: 140 mg%
