Question

A patient presenting with Graves' disease will most likely demonstrate which laboratory finding?

a) Free T4 =3 pmol/L (NL=10-27 pmol/L)
b) TSH=0.04 mIU/L (NL=0.15-4.0 mIU/L)
c) ESR=42 mm/h (NL <15 mm/h)
d) TWBC=12,400 cells/mm3 with 70% neutrophils

Answer 1

In Graves' disease, the most likely laboratory finding is a low TSH level.

Step-by-step explanation:

A patient presenting with Graves' disease will most likely demonstrate which laboratory finding? The correct laboratory finding in a patient with Graves' disease is b) TSH=0.04 mIU/L (NL=0.15-4.0 mIU/L).

In Graves' disease, the body produces autoantibodies that mimic the action of TSH hormone, resulting in overproduction of thyroid hormones. As a result, the thyroid hormone levels are elevated, and the production of TSH, which normally stimulates the thyroid gland, is suppressed. Therefore, in Graves' disease, we expect to see a low TSH level.
