    test that measures blood glucose levels after a 12 hour fast
  45. glucose tolerance test (GTT)
    test that measures the bodys ability to metabolize carbohydrates by administering a standard dose of glucose and measuring glucose levels in the blood and urine at regular intervals
  46. insulin tolerance test
    test that determines insulin levels in serum (blood) by administering insulin and measuring blood glucose levels in blood at regular intervals
