They pulled Free T-3 and T-4 and the Total T-3 and T-4. Only on the first lab did T-4 show high.
You need more than a TSH with those numbers and you need additional tests to determine the cause of the variations. See if the endo will take you before March and try to get another blood draw ordered by the endo for a full panel not jusy TSH.
no its not...make sure they are testing the complete thyroid panl..t4, free t4, t3, free t3, antibodies, t7 etc.. I am sure one else here can chime in and give you the complete panel.
