  21. an enzyme that converts hydrogen peroxide to water and oxygen
  22. after eating
  23. a precursor of insulin, inactive form of insuline
  24. Hormones such as ___________ act in a variety of ways to increase bloodglucose concentration
    • growth hormone,
    • epinephrine,
    • somatostatin,
    • cortisol,
    • glucagon
  25. process of formation of new glucose is called?
  26. Hypoglycemia accrues due to which hormone deficiency?
  27. Diagnostic test are performed for diabetes and hypoglycemia?
    • Fasting blood glucose
    • Oral glucose tolerance test
    • two hour postprandial glucose
    • Hemoglobin A1c
  28. 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
  29. 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.
  30. 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.
