The glucose test, also known as the glucose test, is done in order to check the amount of sugar in the blood, which is called glycemia, and is considered the main test to diagnose diabetes.
To perform the exam, the person must be fasting, so that the result is not influenced and the result can be a false positive for diabetes, for example. From the result of the exam, the doctor may indicate readjustment of the diet, use of antidiabetic medications, such as Metformin, for example, or even insulin.
The reference values for the fasting glucose test are:
- Normal: less than 99 mg / dL; Pre-diabetes: between 100 and 125 mg / dL; Diabetes: greater than 126 mg / dL on two different days.
The fasting time for the fasting glucose test is 8 hours, and the person can only drink water during this period. It is also indicated that the person does not smoke or make efforts before the exam.

Glucose intolerance test
The glucose tolerance test, also called the blood glucose curve test or TOTG, is done on an empty stomach and consists of the ingestion of glucose or dextrosol after the first collection. In this examination, several glucose measurements are made: fasting, 1, 2 and 3 hours after ingesting the sugary liquid provided by the laboratory, requiring the person to remain in the laboratory practically all day.
This test helps the doctor to diagnose diabetes and is usually done during pregnancy, since it is common for glucose levels to rise during this period. Understand how the glucose tolerance test is done.
TOTG reference values
The reference values for the glucose intolerance test refer to the glucose value 2 hours or 120 minutes after glucose intake and are:
- Normal: less than 140 mg / dL; Pre-diabetes: between 140 and 199 mg / dL; Diabetes: 200 mg / dL or more.
Thus, if the person has a fasting blood glucose greater than 126 mg / dL and a blood glucose equal to or greater than 200 mg / dL 2h after taking glucose or dextrosol, it is likely that the person has diabetes, and the doctor must indicate the treatment.
Examination of glucose in pregnancy
During pregnancy it is possible for the woman to have changes in her blood glucose levels, so it is important that the obstetrician request the glucose measurement to check if the woman has gestational diabetes. The test requested can be either fasting glucose or the glucose tolerance test, whose reference values are different.
