A) autoimmune antibody stimulatio of the thyroid gland

B) a TSH-producing tumor of the pituitary gland

C) insufficient TRH production by the hypothalamus

D) a T3-producing tumor of the pituitary gland

3) Why are TSH levels markedly decreased?

A) the free T4 levels are too low to promote TSH production by the pituitary gand

B) the elevated levels of anti-TSH receptor antibodies inhibit release of TSH from the thyroid gland

C) markedly elevated levels of anti-thyroglobulin and anti-thyroid peroxidase antibodies inhibit TSH production by the thyroid gland

D) increased levels of T3 provide for feedback inhibition of TSH production by the pituitary gland

4) Why would this patient exhibit the symptoms of weight loss and heat intolerance?

C) excess thyroid hormones are increasing the metabolic rate

D) an imbalane in the T4:T3 ratio is suppressing the metabolic rate

 
An 11-yo female with no significant past medical history presented with
symptoms of weight loss and heat intolerance. She has also experienced
a decline in grades at school. The physician ordered thyroid function
tests including Free T, T3, TSH, anti-TSH receptor antibodies, anti-
thyroglobulin and anti-thyroid peroxidase antibodies. The results are
shown below.
