d
Increased T3 and T4 levels and an increase in Thyroid Stimulating Hormone
QuestionChoice
This is unlikely to be consistent with the diagnosis of the patient’s case

e
Decreased T3 and T4 levels, but a normal plasma concentration of Thyroid Stimulating Hormone
QuestionChoice
This blood work would be consistent with a diagnosis of hyperthyroidism due to Grave’s Disease or hyper-secreting thyroid tumour

c
Increased T3 and T4 and decreased Thyroid Stimulating Hormone
QuestionChoice
This would be consistent with a diagnosis of primary failure of the thyroid gland, with 90% of the cases being due to Hashimoto’s Thyroiditis or due to a lack of dietary iodine
