Free T3 is the unbound, active form of the thyroid hormone T3. It regulates metabolism, energy production, heart rate, and body temperature. Abnormal Free T3 levels can indicate hyperthyroidism (elevated levels) or hypothyroidism (low levels), guiding treatment decisions.
The Free T3 at-home blood test measures Free triiodothyronine (Free T3), the metabolically active thyroid hormone responsible for regulating your energy, weight management, and temperature control. It’s part of our endocrinology blood test kits designed for convenient home sampling.
Consider a Free T3 blood test kit if you experience:
Our home blood testing kit uses a small-volume TDL Tiny self-sampling collection tube. Simply perform a quick finger prick, collect a few drops of blood, seal the tube, and post it back. Accurate results from at-home blood tests in just days.
All Mayfield Clinic tests are GP-led. Once your Free T3 results are ready, you can book an optional follow-up appointment—either in person or via video consultation (additional fees apply)—to discuss your hormone levels and next steps.
Our at-home Free T3 blood test kit uses a high-precision laboratory method to analyse your tiny finger-prick sample. Results are comparable to traditional venous sampling in accuracy and reliability.
1. Wash and dry your hands thoroughly. 2. Use the lancet provided to prick your fingertip. 3. Collect the drops of blood in the TDL Tiny collection tube. 4. Seal the tube, complete the form, and post it back in the pre-paid envelope. Full instructions are in the kit kit for a seamless at-home sampling experience.
The Free T3 home blood testing kit measures the levels of Free T3 (triiodothyronine), the active thyroid hormone responsible for regulating metabolism. It’s designed for at-home blood tests, allowing you to finger-prick a small blood sample and send it back to our lab for analysis.
We recommend testing in the morning before breakfast, ideally on the same day each month if monitoring treatment. Avoid heavy exercise or major dietary changes for 12 hours prior to testing.
