Why Does It Take A Long Time To Draw Blood To Diagnose Diabetes?
Morning, I want to ask why the blood glucose tolerance test is done in an interval of 1/2, 1, even 2 hours? And if people who have hypoglycemia, including diabetes? Thank you
Hello, Ms. Ayu Ninda Pertiwi. Thank you for the question submitted to HealthReplies.com.
Oral glucose tolerance test (TTGO) is an examination method to assess the body's response to sugar intake. This test can help differentiate above normal sugar levels in individuals with diabetes and prediabetes.
Until now, the method of implementing TTGO recommended by the Indonesian Endocrinology Association in 2015, which refers to the World Health Organization (WHO) guidelines, states that TTGO is initiated by examining fasting blood glucose levels after fasting patients for at least 8 hours. After that, adult patients are given 75 grams of glucose dissolved in 250 mL of water and taken within 5 minutes, then asked to return to fasting until blood samples are taken for examination of blood glucose levels 2 hours after glucose loading. The diagnosis of diabetes on TTGO examination can be established if fasting plasma glucose levels> = 126 mg / dL, or if plasma glucose levels 2 hours after TTGO> = 200 mg / dL.
Determination of the time limit for the examination, the glucose level given, and the cut-off value for the diagnosis of diabetes is the result of a consensus of experts in the field of metabolic, hormonal, and diabetes based on the results of diagnostic studies. These values indicate a good ability to be able to distinguish differences in circumstances between diabetic, prediabetes, and normal individuals.
Regarding hypoglycemia, this is one of the acute complications that can occur in diabetic patients. However, hypoglycemia is not a diagnosis criteria for diabetes.
