you have no idea! None of the above is likely to be the correct diagnosis.
Which one of the following sets of blood test results would one most likely in the case of a patient with Grave’s disease?
T4 = High, TSH = High, Thyroid-Stimulating Antibodies = High
T4 = High, TSH = High, Thyroid-Stimulating Antibodies = Low
T4 = High, TSH = Low, Thyroid-Stimulating Antibodies = High
T4 = High, TSH = Low, Thyroid-Stimulating Antibodies = Low
T4 = Low, TSH = High, Thyroid-Stimulating Antibodies = High
T4 = Low, TSH = High, Thyroid-Stimulating Antibodies = Low
T4 = Low, TSH = Low, Thyroid-Stimulating Antibodies = High
T4 = Low, TSH = Low, Thyroid-Stimulating Antibodies = Low
Which one of the following statements is false?
Granulosa cells surround the ovulated oocyte.

FSH stimulates granulosa cells directly, while LH stimulates granulosa cells indirectly.
If a man with autoimmune disease developed antibodies that blocked FSH receptors, circulating levels of inhibin would be lower than normal.
A.the patient has diabetes.
B.the patient has Grave’s disease.
C.the patient is suffering side effects from long-term glucocorticoid therapy.
