The thyroid is a little gland at the front of your neck, shaped like a bow tie, which helps all of the cells of your body to work in balance and at the right speed, it releases thyroid hormones to do this.
If you have an underactive thyroid, you may feel sluggish, tired or depressed. You may experience dry skin, hair or nails, constipation or weight gain.
Your results will give you an indication of whether your thyroid is functioning normally or not. When we send you your results in your secure account, we will also give you help and advice on what to do next.
