Hyperthyroid (graves disease) Labs
TSH level would be __
T3/T4 would be ___ - ANSWER- TSH would be low
Serum free T3 and T4 would be elevated.
Remember the knocking on the door analogy:
the pituitary gland recognizes that the t3 and t4 are elevated, so it will not send anyone
to knock on the thyroids door to increase it (aka will not send out any more TSH)
Hypothyroidism (hashimotos's) labs
TSH level would be __
T3/T4 would be ___ - ANSWER- TSH level is high
T3& T4 are low.
This is because the TSH is trying to get the thyroid to produce more T3 and T4, but the
thyroid cant. Hence the patient will need synthetic T4. (synthroid)
