A member asked:

What does normal tsh and high free t4 mean? have had the labs checked twice and having many symptoms (tired, heart palpitations, headaches, etc.?

A doctor has provided 1 answer

The actual active thyroid hormone is Free T3. The Free T4 converts to Free T3 to be active. Measure your Free T3 and actually see if you are hypo or hyperthyroid by that test. If your thyroid is normal, then there is another cause for your symptoms. Stress and lack of sleep can also cause those symptoms.
