What is FT3?
Free Triiodothyronine, abbreviated FT3, is a thyroid hormone in the blood that is essential for regulating metabolism, heart function, digestion, and brain development.
Why should FT3 be tested?
Testing FT3 is useful for evaluating thyroid function. It is particularly helpful in diagnosing hyperthyroidism or hypothyroidism, especially if other tests, such as those for TSH or FT4, show abnormal results.
What does it indicate?
FT3 levels provide information about how active the thyroid gland is. It aids in the diagnosis of thyroid diseases and in monitoring the treatment of thyroid conditions.
What does a high FT3 level mean?
A high FT3 level may indicate hyperthyroidism (an overactive thyroid gland), which can lead to symptoms such as weight loss, palpitations, increased anxiety, insomnia, and hand tremors.
What does a low FT3 level mean?
A low FT3 level may suggest hypothyroidism (an underactive thyroid gland), which can result in symptoms such as weight gain, fatigue, depression, cold intolerance, and dry skin.
Frequently asked questions
Answers to what people usually want to know.
How does it work from order to result?
After ordering we generate a referral letter and email you the instructions. You pick a collection point yourself and book an appointment there. Blood is drawn at the location, processed at the lab, and your result arrives digitally.
How quickly can I get tested?
Usually very quickly. Collection points typically have slots within a few days, sometimes even same-day. It depends on how busy the location is. For a few specialist analyses we first ship collection materials, which takes a bit longer.
Do I need to book an appointment?
At most collection points yes. Some accept walk-ins. This is clearly indicated per location. You choose the location that works best for you.
