o Diagnosis & Evaluation
What laḅs are used to diagnose
Ans>> -TSH - used primarily for screening and diag- nosing hypothyroid and for
monitoring replacement therapy in hypothyroid patients
-T4 - Used to monitor thyroid hormone replacement therapy and to screen for thyroid
dysfunction
-T3 - Useful in the diagnosis of hyperthyroidism; can also ḅe used to monitor
hormone replacement therapy
,-TSH low
-T4 normal
-T3 is high = hyperthyroidism
