Glucose, 7th Specimen details
What Glucose, 7th Specimen shows
A glucose tolerance test measures how your body handles a measured dose of sugar. Blood samples are taken at set times, usually starting with a fasting sample before you drink a glucose solution and continuing at intervals afterwards, with the exact timing depending on the protocol your clinician ordered. This value is the glucose level in the seventh sample. Together, the samples show how quickly your glucose rises and how well insulin brings it back down. A higher result than expected at this point can suggest impaired glucose tolerance or diabetes, while a low result later in the test can point to reactive hypoglycemia. Each value is interpreted as part of the full curve, not on its own.
Tests that include Glucose, 7th Specimen
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, 2nd Specimen Your blood glucose in the second sample of a multi-sample glucose tolerance test, showing how your body handles sugar at that point after the glucose drink.
- Glucose, 3rd Specimen Your blood glucose in the third sample of a multi-sample glucose tolerance test, showing how your body handles sugar at that point after the glucose drink.
- Glucose, 4th Specimen Your blood glucose in the fourth sample of a multi-sample glucose tolerance test, showing how your body handles sugar at that point after the glucose drink.
- Glucose, 5th Specimen Your blood glucose in the fifth sample of a multi-sample glucose tolerance test, showing how your body handles sugar at that point after the glucose drink.
- Glucose, 6th Specimen Your blood glucose in the sixth sample of a multi-sample glucose tolerance test, showing how your body handles sugar at that point after the glucose drink.
- Glucose, 7th Specimen Your blood glucose in the seventh sample of a multi-sample glucose tolerance test, showing how your body handles sugar at that point after the glucose drink.
