T4 (thyroxine) circulates in body in a bound form with thyroxine-binding globulin and albumin. Less than 0.3% of the total T4 is free fraction (FT4) and is the active form. Free T4 test measuring free T4 levels, more accurately reflect how the thyroid gland is functioning when checked with TSH.
Thyroid hormones are essential for growth and metabolism. Following are the symptoms of hyperthyroidism: weight loss, rapid heartbeat, tremors, sweating, anxiety, increased sensitivity to heat, etc.
Whereas patients with hypothyroidism suffer from weight gain, fatigue, slow heart rate, increased sensitivity to cold, depression, dry and thin hair etc.

Frequently Asked Questions
Free T4 test is done along with TSH to
1. Diagnose thyroid disorders both overt & subclinical
2. Monitoring patients on thyroid replacement therapy
In a very small group of patients only T3 & FT3 is increased.
In pregnancy due to increase in thyroglobulin and decrease in albumin may cause increase of T3 & T4 levels, without actually impacting body functions hence testing FT3 and FT4 is more representative
Free T4 test measures levels of FT4 hormone in blood
Free T4 test requires a blood sample. A tourniquet (elastic) band is placed tightly on the upper arm. The patient is then asked to make a fist. This helps in the build-up of blood filling the veins. The skin is disinfected before needle insertion and the blood sample is collected in vacutainer.
