Step 1
It is 520 pmol/L, which is higher than the normal range. This indicates that patient A has an elevated level of Free T4. Show more…

Mrs. TT had a laboratory blood test done. Her test result shows that her thyroxine (T4) level is 7 picomol/L and thyroid-stimulating hormone (TSH) level is 8 mlU/L. What is a likely diagnosis for Mrs. TT based on her test result? Briefly explain your answer. T4 reference range: 10-25 picomol/L TSH reference range: 0.4-5 mlU/L

1. Diagram the hypothalamic-pituitary-thyroid axis. Make sure to include the feedback loops and spell out the hormone names. 2. What is the physiological role of thyroid hormones? Does T3 or T4 play a larger role in the target tissues? Explain. 3. If you gave a person with primary hypothyroidism (iodine deficiency) an injection of TSH, would T3 and T4 levels increase? Why or why not?
A 24-year-old woman presents 2 months postpartum with symptoms of hyperthyroidism. She does not have evidence of Graves' ophthalmopathy. Her TSH level is undetectable, and free T4 is two times the upper limit of normal. Questions 1. What are possible causes for her thyrotoxicosis? 2. What tests would be useful to sort out the cause of her thyrotoxicosis?
