Free Thyroxine (FT4) Blood Test
What it measures
Thyroid Function Tests
Clinical significance
Free thyroxine (free T4) tests are used to help evaluate thyroid function and diagnose thyroid diseases, including hyperthyroidism and hypothyroidism. The test may also be used to help evaluate a patient with an enlarged thyroid gland, called a goitre.
The normal range for free T4 in adults is 0.8 to 1.8 ng/dL or 12 to 30 pmol/L.
High levels of any of these tests (total T4, free T4, or free T4 index) may indicate an overactive thyroid, also known as hyperthyroidism.
Low levels of any of these tests (total T4, free T4, or free T4 index) may indicate an underactive thyroid, also known as hypothyroidism.
Your doctor may suspect that one of these conditions is present if you have symptoms such as: eye issues (dryness, irritation, puffiness, and bulging), skin dryness or skin puffiness, hair loss, hand tremors, changes in heart rate, changes in blood pressure. You may also experience more general symptoms, such as: weight changes, difficulty sleeping or insomnia, anxiety, fatigue and weakness, intolerance to cold, sensitivity to light, menstrual irregularity.
