Sample Collection Options for your Free T4 Test
Free T4 (FT4 or free thyroxine) is often used in conjunction with TSH to assess thyroid function at a basic level. It is the active form of thyroxine, released from the thyroid gland in the neck. Thyroxine's role is to control metabolism - release of energy from all cells of the body. A lack of thyroxine leads to symptoms which include tiredness and weight gain, whereas an excess will lead to weight loss, rapid heart rate and anxiety. It is generally believed that the Free T4 level is a reliable indicator of thyroid status - ie whether the gland is over-active (hyperthyroidism) or underactive (hypothyroidism).
There's a reason that over 30% of Blue Horizon Kit requests are from patients that have used us before.

Utterly patient, kind and helpful, kit arrived next day, as did my results. 5 stars well-deserved.UK
Great service and product. The turn around is brilliant (mostly - there was a glitch during the early part of the Covid pandemic, but that seems to be resolved now). Tests are recognised by the medical profession so I am able to use the results to get the treatment I need without further tests.UK
I had various questions which they answered via email/webchat and the timing of getting a kit, sending it back and getting the results was good.UK
