A nurse reviews laboratory data for an adult patient. The serum TSH is below normal limits. When the patient inquires about the significance of this finding, what is the nurse's best response?
1. Hypothyroidism causes the TSH to decrease.
2. The test is probably erroneous, as the patient does not exhibit a goiter.
3. TSH is not a good screening test for thyroid disease.
4. The low TSH is consistent with hyperthyroidism.
