Decreased thyrotropin receptor antibodies

Decreased free thyroxine index

Decreased triiodothyronine

Decreased thyroid-stimulating hormone (TSH)

Answer and Explanation

The Correct Answer is D

A. Decreased thyrotropin receptor antibodies: Graves' disease is characterized by the presence of thyrotropin receptor antibodies, so they are typically increased, not decreased.

B. Decreased free thyroxine index: Graves' disease typically results in increased levels of thyroid hormones, not decreased.

C. Decreased triiodothyronine: T3 levels may be elevated in Graves' disease due to increased thyroid hormone production.

D. Decreased thyroid-stimulating hormone (TSH): Graves' disease causes excessive thyroid hormone production, leading to suppressed TSH levels. TSH is typically low in hyperthyroidism because the thyroid gland is overactive and not being stimulated by the pituitary gland.

Correct Answer is C

Explanation

A. Systemic lupus erythematosus (SLE): SLE is an autoimmune disease but is not directly linked to the pathophysiology of HIT.
