Glucose, 1-Hour (after 75 g Oral Glucose) details
What Glucose, 1-Hour (after 75 g Oral Glucose) shows
In a 75 g oral glucose tolerance test, you drink a standard glucose solution after fasting, and blood samples are taken at set times to see how your body clears the sugar. This value is your glucose level one hour after the drink. It is used in evaluating diabetes, prediabetes and, in pregnancy, gestational diabetes. A higher result than expected at one hour suggests glucose is not being cleared efficiently, which can point to impaired glucose tolerance or diabetes, while a lower value suggests a normal response. The one-hour result is interpreted together with the fasting and later samples, and pregnancy and non-pregnancy criteria differ.
Tests that include Glucose, 1-Hour (after 75 g Oral Glucose)
This test is primarily used to diagnose diabetes in children and adults who are not pregnant. For pregnant women, a different test is recommended. To ensure accurate results, patients need to fast overnight and then consume a 75g glucose solution. A fasting blood sample is taken immediately after. For children, the glucose amount is adjusted to their body weight. Diabetes may be diagnosed if fasting glucose levels are ≥126 mg/dL or if glucose levels are ≥200 mg/dL two hours after consuming the glucose.
- Fasting Glucose Blood sugar measured after fasting, one of the primary tests used to screen for prediabetes and diabetes.
- Glucose, 1-Hour (after 75 g Oral Glucose) Your blood glucose one hour after a 75 g glucose drink, part of an oral glucose tolerance test used to assess how your body handles sugar.
- Glucose, 2-Hour (after 75 g Oral Glucose) Your blood glucose two hours after a 75 g glucose drink, a key value in the oral glucose tolerance test for diabetes and prediabetes.
For appropriate interpretation of this test, the patient must fast overnight and ingest a 75 g load of glucose, immediately after a fasting specimen is obtained. (for children, the glucose load is 1.75 g/Kg of body weight, up to 75). The diagnosis of diabetes is made if glucose exceeds 200 mg/dL in the 2 hour specimen and in any preceding specimen.
- Fasting Glucose Blood sugar measured after fasting, one of the primary tests used to screen for prediabetes and diabetes.
- Glucose, 1-Hour (after 75 g Oral Glucose) Your blood glucose one hour after a 75 g glucose drink, part of an oral glucose tolerance test used to assess how your body handles sugar.
- Glucose, 2-Hour (after 75 g Oral Glucose) Your blood glucose two hours after a 75 g glucose drink, a key value in the oral glucose tolerance test for diabetes and prediabetes.
- Glucose, 3-Hour (after 75 g Oral Glucose) Your blood glucose three hours after a 75 g glucose drink, part of an extended glucose tolerance test that also looks for late drops in sugar.
- Glucose, 30-Minute (after 75 g Oral Glucose) Your blood glucose 30 minutes after a 75 g glucose drink, part of an extended glucose tolerance test that tracks your early sugar response.
This test measures plasma glucose levels to help diagnose and manage carbohydrate metabolic disorders. It's particularly useful for identifying conditions of abnormally high (hyperglycemia) or low (hypoglycemia) blood sugar levels.
- Fasting Glucose Blood sugar measured after fasting, one of the primary tests used to screen for prediabetes and diabetes.
- Glucose, 1-Hour (after 75 g Oral Glucose) Your blood glucose one hour after a 75 g glucose drink, part of an oral glucose tolerance test used to assess how your body handles sugar.
- Glucose, 2-Hour (after 75 g Oral Glucose) Your blood glucose two hours after a 75 g glucose drink, a key value in the oral glucose tolerance test for diabetes and prediabetes.
