Question

Quizplus · Accepted Answer

Graves' disease is an autoimmune disorder that causes overactivity of the thyroid gland. The presence of increased serum thyroid antibodies, mainly TSH receptor antibodies (TRAb), is a hallmark laboratory finding in Graves' disease. This can be used to diagnose the condition.

Answer: C 
 Decreased radioactive iodine uptake is another laboratory finding in Graves' disease. In this condition, the thyroid gland takes up and uses iodine excessively due to overstimulation, leading to reduced radioactive iodine uptake. This is a typical finding in Graves' disease, which can confirm the diagnosis.

Therefore, the best choices are B and C.
