No special preparation is needed for the Free T4 test. However, some medications may affect the results of the test, so it's important to discuss with your healthcare provider about any medications you are taking.

The Free T4 test is a simple blood test. A healthcare professional will draw a blood sample from a vein in your arm using a small needle. After the needle is inserted, a small amount of blood is collected into a test tube or vial.

A high Free T4 level may indicate an overactive thyroid (hyperthyroidism). Symptoms can include rapid heart rate, anxiety, weight loss, difficulty sleeping, tremors in the hands, weakness, and sometimes a swollen thyroid gland (goiter) or eye problems.

A low Free T4 level may indicate an underactive thyroid (hypothyroidism). Symptoms can include weight gain, dry skin, constipation, cold intolerance, and fatigue.

Free T4 is the portion of T4 that is not bound to proteins in the blood and is free to enter body tissues. Total T4 includes both free T4 and T4 bound to proteins. The Free T4 is typically a more accurate reflection of thyroid hormone function than Total T4.

The frequency of the Free T4 test should be determined by your healthcare provider based on your health condition and response to treatment. If you are being treated for a thyroid disorder, you will likely be tested more frequently.

Treatments may include medications to regulate the production of thyroid hormone, radioactive iodine to slow down hormone production, or surgery to remove part of the thyroid gland.
