The glucose test, also known as a glucose test, is done to check the amount of blood sugar, called blood sugar, and is considered the primary test for diagnosing diabetes.
To perform the test, the person must be fasting, so that the result is not influenced and the result can be a false positive for diabetes, for example. Depending on the test result, your doctor may indicate a dietary adjustment, the use of antidiabetic medications, such as metformin, for example, or even insulin.
The reference values for the fasting blood glucose test are
The fasting time for the fast 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 any effort before the test.
Know your diabetes risk by performing the following test:
The glucose tolerance test, also known as a GLUCOSA curve test, or TOTG, is fasting and involves ingestion of glucose or dextrosol after the first sample. This test performs several glucose measurements: with the head empty, 1, 2 and 3 hours after ingestion of the sweet liquid provided by the laboratory, forcing the person to stay in the lab most of the day.
This test helps your doctor diagnose diabetes and is usually done during pregnancy, as it is common for glucose levels to increase during this period. Understand how the glucose tolerance test is performed.
The reference values for the glucose intolerance test refer to the glucose value 2 hours or 120 minutes after glucose intake and are:
Thus, if the person has fasting blood glucose levels above 126 mg/dL and blood sugar levels of 200 mg/dL 2 hours after ingestion of glucose or dextrosol, the person is likely to be diabetic and the doctor should indicate treatment.
During pregnancy, the woman may have changes in her blood sugar level, so it’s important for the obstetrician to order blood glucose measurement to check if the woman has gestational diabetes. The requested test may be fasting blood glucose or glucose tolerance, with different reference values.
