The flashcards below were created by user elinor on FreezingBlue Flashcards. What would you like to do?


  1. Blood serum test
    Blood test to measure the level of substances such as calcium, electorlytes, testosterone, insulin,and glucose.  Used to assist in determining the function of various endocrine glands.
  2. Fasting blood sugar (FBS)
    Blood test to measure the amount of sugar circulating throught the body after a 12-hour fast.
  3. glucose tolerance test (GTT)
    Test to determine the blood sugar level.  A measured dose of glucose is given to a patient either orally or intravenously.  Blood samples are then drawn at  certain intervals to determine the abiltiy of the patient to use glucose.  Used for diabetic patients to determine their insulin response to glucose.
  4. protein-bound iodine test (PBI)
    Blood test to measure the concentration of thyroxine (T4) circulating in the bloodstream.  The iodine becomes bound to the protein in the blood and can be measured.  Useful in establishing thyroid function.
  5. radioimmunoassay (RIA)
    • radi/o = ray
    • immun//o = protection

    Blood test that uses radioactively tagged hormones and antibodies to measure the quantity of hormone in the plasma.
  6. thyroid function test (TFT)
    Blood test used to measure the levels of thyroxine, triiodothyronien, and thyroid-stimulating hormone in the bloodstream to assist in determining thyroid function.
  7. total calcium
    Blood test to measure the total amount of calcium to assist in detecting parathyroid and bone disorders.
  8. two-hour postprandial glucose tolerance test
    Blood test to assist in evaluating glucose metabolism.  The patient eats a high carbohydrate diet and then fasts overnight before the test.  Then the blood samlple is taken 2 hours after a meal.
  9. Thyroid  echography
    -graphy = process of recording

    Ultrasound examination of the thyroid that can assist in distinguishing a thyroid nodule from a cyst.
  10. Thyroid scan
    Test in which radioactive iodine is administered that localizes in the thyroid gland.  The gland can then be visualized with a scanning device to detect pathology such as tumors.
