Many people in the UK experience unexplained symptoms—such as fatigue, mood changes or weight gain—without knowing if their thyroid might be involved. Now, getting answers is easier than ever with the Free T3 Home Blood Test Kit from Mayfield Clinic.
Our self-sampling kit is designed for UK adults seeking clarity about their thyroid. It uses a TDL Tiny Self-Sampling Kit—a small-volume, finger-prick blood collection system that’s easy to use at home.
Free T3 is a key indicator of your thyroid’s real-time performance. Low or high levels can contribute to symptoms like tiredness, poor concentration, or shifts in body weight. Testing now means you can start making lifestyle changes or seek treatment sooner.
Take control of your thyroid. Simple, fast home testing puts your health in your hands.
You’ll receive a pre-paid kit, collect a finger-prick sample, post it back in the included envelope, and get results online within one day of the lab receiving your sample.
Our kit uses a small, gentle device similar to those for home glucose monitoring. Most people experience only minor discomfort, if any.
If your results are outside the expected range, our doctors can offer guidance on next steps. You may be advised to have further tests or visit your NHS GP for treatment.
