FBG and OGTT: Fbg is fasting blood glucose (sugar) and ogtt is an oral glucose tolerance test. For the ogtt, a woman comes in fasting, drinks a sweet liquid with a set amount of glucose. Blood is drawn just before the woman drinks the glucose solution, and at several time points afterwards for up to 3 hours (~ 4 draws total). Having a high glucose for two of the readings means she has gestational diabetes.
