About this test

1 in 7 people live with a thyroid condition with symptoms ranging from low energy and depression to unexplained weight gain and insomnia. If you don’t feel right but you can’t put your finger on why, this simple thyroid test can tell you if it's your thyroid. IS YOUR THYROID MAKING YOU DEPRESSED? The thyroid gland is a small butterfly-shaped gland in the front of the neck which uses iodine to produce hormones which control your metabolism. These hormones regulate the speed at which your brain, heart, muscles and liver work. Every cell in the body depends on thyroid hormones to produce energy. Your thyroid is intricately connected with every system in your body, so if a thyroid test reveals it’s not working properly you most likely won’t feel great. Thyroid disorders typically present later in life, and if you're a woman over 35 your odds of an abnormal thyroid test result increase significantly. Thyroid conditions can cause a wide variety of seemingly unrelated symptoms. An abnormal thyroid rest result can reveal fatigue and low energy levels, depression, unexplained weight gain (or loss), slow heart rate, feeling cold (even on warm days), muscle aches, dry skin, hair loss, constipation, difficulty concentrating, fertility problems, feelings of agitation and nervousness, insomnia, diarrhoea, increased sweating, heart palpitations… it’s a long list! Read our blog [https://www.i-screen.co.nz/blog/hypothyroidism-test] to find out more. Our thyroid test can help you work towards higher energy levels, improved hormone function, weight regulation and relief from other thyroid related symptoms.

What we measure

THYROID FUNCTION

Your thyroid gland produces hormones that regulate growth and energy expenditure.

TSH
Communicates with the thyroid gland to produce T3 and T4 which regulate metabolic functions. High TSH thyroid test levels indicates an underactive thyroid, and low levels an overactive thyroid.
FT4
Measures the thyroxine that is freely circulating and able to regulate metabolism. High FT4 thyroid test levels indicate an overactive thyroid, and low levels an underactive thyroid.
FT3
Measures the triiodothyronine that is freely circulating. High FT3 thyroid test levels indicate an overactive thyroid, and low levels an underactive thyroid.
