Thyroxine (T4) is the most prevalent thyroid hormone produced by the thyroid gland.

Tests which include a Free Thyroxine test:
High Free T4 can be associated with an overactive thyroid gland (hyperthyroidism), particularly when it occurs alongside typical clinical symptoms.
Changes in thyroid function can affect many body systems and are often reviewed further to clarify the cause.
Some medicines (including certain contraceptive birth control pills, epilepsy drugs, and large doses of aspirin) can interfere with Total T4 test results. In general, Free T4 levels are minimally affected by these medications.
Low free T4 can be associated with an underactive thyroid gland (hypothyroidism), particularly when it occurs alongside symptoms commonly linked to reduced thyroid function.
