Glucose screening is usually done between 24 and 28 weeks of pregnancy. Between 24 and 28 weeks of pregnancy.
During this second test, called the 100-gram oral glucose tolerance test, your blood glucose level will be tested four times during a three-hour period after drinking the cola-like drink. If two out of the four blood tests are abnormal, you are considered to have gestational diabetes. All pregnant women should be screened for gestational diabetes during their pregnancy. Screening may be done by taking the woman's medical history and examining certain risk factors, but an oral glucose tolerance test is also recommended. Glucose screening is usually done between 24 and 28 weeks of pregnancy. If the test, which screens for gestational diabetes, reveals elevated levels of blood glucose (sugar), a glucose tolerance test is then given to confirm the gestational diabetes diagnosis. There are several tests intended to identify gestational diabetes in pregnant women. The first, called the Glucose Challenge Screening, is a preliminary screening test performed between 26-28 weeks. If a woman tests positive during this screening test, the second test, called the Glucose Tolerance Test, may be performed. This test will diagnose whether diabetes exists or not by indicating whether or not the body is using glucose (a type of sugar) effectively. Prior to the taking the glucose tolerance test, your doctor will ask you to make sure and eat at least 150mg of carbohydrates (about what you will get from a slice or two of bread) for three days prior to the time you will be asked to fast. In fact, only about a third of women who test positive on the glucose screen actually have the condition. If you test positive on the screening, you'll need to take the glucose tolerance test (GTT) – a longer, more definitive test that tells you for sure whether you have gestational diabetes.

Ultrasound exam Find out what doctors look for and how ultrasound exams are done. Gestational diabetes is a high blood sugar condition that some women get during pregnancy. Between 2 and 5 percent of expectant mothers develop this condition, making it one of the most common health problems during pregnancy. The oral glucose tolerance test (OGTT) was the gold standard for making the diagnosis of type 2 diabetes. It is still commonly used during pregnancy for diagnosing gestational diabetes. With an oral glucose tolerance test, the person fasts overnight (at least 8 hours, but not more than 16 hours).  The oral glucose tolerance test is used to screen for gestational diabetes. Gestational diabetes is a specific type of diabetes that can develop in some women late in pregnancy (usually after the 24th week). Women who develop this complication do not have diabetes before becoming pregnant. All pregnant women should be screened for gestational diabetes during their pregnancy. Screening may be done by taking the woman's medical history and examining certain risk factors, but an oral glucose tolerance test is also recommended.
