Blood Sugar Test

wife is going to have the blood sugar test today.. she is in her 28-week pregnancy.

this is the test.

An oral glucose tolerance test (OGTT) measures plasma glucose at timed intervals over a 3-hour period. The person being tested starts the test in a fasting state (having no food or drink except water for at least 10 hours but not greater than 16 hours). An initial blood sugar is drawn and then the person is given a drink with high amount of sugar in it (75 grams of glucose or 100 grams for pregnant women). The person then has their blood tested again 30 minutes, 1 hour, 2 hours and 3 hour intervals after drinking the high glucose drink. If the plasma glucose level is 200 mg/dl or more in the blood sample taken 2 hours after drinking high glucose shows that the test is positive.

Gestational diabetes is also diagnosed through OGTT. Glucose levels are normally lower during pregnancy, so the basic values for diagnosis of diabetes in pregnancy are lower. If a woman has two plasma glucose values meeting or exceeding any of the following numbers, she has gestational diabetes: a fasting plasma glucose level of 95 mg/dL, a 1-hour level of 180 mg/dL, a 2-hour level of 155 mg/dL, or a 3-hour level of 140 mg/dL.
