Many UK adults experience unexplained fatigue, brain fog, or difficulty losing (or gaining) weight. These symptoms can be frustrating—especially when routine tests come back normal.
But did you know: Sometimes, your symptoms could be linked to your thyroid, specifically your Free T3 levels.
Your thyroid gland produces several hormones, with T3 playing a critical role in energy levels and metabolism. Free T3 is the active form, circulating in your blood and ready to help regulate vital functions in your body.
It’s common for hypothyroidism or other thyroid imbalances to be missed in standard blood tests, especially if only TSH is checked. Measuring Free T3 can provide a clearer view of your thyroid health.
Mayfield Clinic is pleased to offer a Free T3 Home Blood Test Kit using the TDL Tiny Self-Sampling Kit. This UK service allows you to:
If you’d rather be tested at the clinic, you can also book an in-person blood test with one of our GPs.
If you’re concerned about your thyroid health, learn more or order your Free T3 home blood test kit with Mayfield Clinic today. Take control of your wellbeing—get clarity and peace of mind close to home.
Free T3, or triiodothyronine, is one of the key thyroid hormones and gives insight into how well your thyroid is functioning. It helps regulate metabolism, mood, and energy.
Common symptoms include fatigue, mood swings, weight changes, sensitivity to temperature, and difficulty concentrating. If you have concerns, consider a thyroid blood test for clarity.
You can buy our home test kit on our product page or book in-person testing at Mayfield. If your symptoms are severe, see your GP or refer to the NHS for further advice.
