production of glucose from noncarbohydrate sources
an enzyme that converts glucose to gluconolactone and that is used in glucose analytical methods
an enzyme that converts glucose to gluconic acid and that is used in glucose analytical methods
hemoglobin modified by the binding of glucose to the beta globin chains of hemoglobin?
hemoglobin A1c (HbA1c)
glycated hemoglobin (GHb)
the storage form of glucose found in high concentration in the liver
conversion of glucose to glycogen
the conversion of glycogen to glucose

blood glucose concentration below normal
the pancreatic hormone essential for proper metabolism of blood glucose and maintenance of blood glucose levels
irregular-shaped clusters of cells scattered throughout the pancreas that contain alpha cells,beta cells, delta cells, and pancreatic polypeptide (PP) secreting cells
islets of Langerhans
analysis of blood glucose at timed intervals following ingestion of a standard glucose dose
oral glucose tolerance test (OGTT
an enzyme that converts hydrogen peroxide to water and oxygen
a precursor of insulin, inactive form of insuline
Hormones such as ___________ act in a variety of ways to increase bloodglucose concentration
process of formation of new glucose is called?
Hypoglycemia accrues due to which hormone deficiency?
Diagnostic test are performed for diabetes and hypoglycemia?
Fasting blood glucose
Oral glucose tolerance test
two hour postprandial glucose
which test is performed on a blood sample taken when the patient has not eaten or taken in calories for 8 hours or longer. Can be performed from a fingerstick, and the results can be obtained while the patient is still in the physician’soffice
Fasting Blood Glucose
Explain how the OGTT is performed.
fasting blood glucose sample is drawn and tested and a urine sample was obtained.
patient consumed a beverage containing a standard glucose dose
Blood and urine samples were subsequently collected at set intervals, typically 30 minutes and 1, 2, and 3 hours.
which step is important during specimen collection for glucose tests and why?
Blood cells metabolize glucose and can rapidly lower the specimen’s glucose concentration, causing a false low glucose value.
Therefore,serum or plasma must be separated from the blood cells as soon as possible after collection.
