The patient with acromegaly asks the purpose of the glucose tolerance test (GTT). The nurse responds by saying that:
1. "The doctor wants to know if you have either diabetes or acromegaly."
2. "The growth hormone will cause the glucose to be used up very quickly during the test."
3. "It measures the growth hormone in the presence of oral glucose levels at speci-fied times."
4. "It tells whether your thyroid reacts to the high levels of sugar taken during this test."
3
The level of growth hormone will drop in the presence of oral glucose. In the patient with acromegaly, the growth hormone level stays the same. The GTT is the best diagnostic tool for acromegaly.
