Intravenous Glucose Tolerance Test It is used to assess the efficiency of insulin release of the pancreas or the effectiveness of insulin. It is not a talent test to see how much sugar a person can take. Process: Glucose is intravenously injected directly into the bloodstream. Blood glucose levels are measured every 15 minutes. Findings: People with simple diabetes do not have the peak glucose level. People with diabetes may have a delayed peak and a slower decrease in blood glucose levels. Limitations: It can be difficult to assess the exact time of glucose absorption from the gut. This test may miss the early stage of diabetes. Hemoglobin A1C test measures the amount of hemoglobin attached to glucose molecules in the bloodstream. Interpretation: HbA1c specifies how well diabetes is being controlled. Normal: < 5.7% Prediabetes: 5.7 - 6.4% Diabetes: > 6.5% If HbA1c is 8 month average It is a live span of red blood cells A HbA1c level of 8% for 2 months might be a sign of diabetes. Changes over time: HbA1c test is a good way to check long-term blood sugar control. HbA1c test can be used to monitor diabetes management. HbA1c Measures average blood glucose levels over the past 2-3 months. Reflects glycosylated hemoglobin. Interpretation: HbA1c specifies how well diabetes is being controlled. Prediabetic: 5.7-6.4% Normal: < 5.7% Diabetic: > 6.5% Limitations: The test cannot be used to diagnose diabetes in children or the gestational diabetes. The test may not be accurate in cases of anemia or other types of blood diseases.
