Understanding your thyroid panel: TSH, free T3, free T4, and antibodies

A thyroid panel is more than TSH. Many persistent fatigue and weight complaints sit in the gap between a normal TSH and poor conversion or autoimmune context. This guide explains what each marker contributes and when follow-up is warranted.[4]

TSH alone can miss clinically important thyroid context.

Free T3 and free T4 help explain conversion and availability patterns.

Antibody testing matters when autoimmune thyroid risk is suspected.
