A thyroid hormone level screening is a blood test that measures the levels of various hormones produced by your thyroid gland. These hormones include various thyroid function indicators.
An imbalance of any of these hormones can wreak havoc with your wellbeing. Did you know thyroid disorders are 15 times more common in women than in men? If you are considering getting a thyroid hormone level screening, you are in great hands, as our caring team is on standby to help get your thyroid health back on track.
Your thyroid is a butterfly-shaped gland located at the base of your neck and it forms part of an intricate network of glands called the endocrine system (a system responsible for coordinating multiple bodily activities). Your thyroid gland is specifically tasked with regulating various metabolic processes throughout your body by producing hormones that influence your metabolism, growth, and development.
These hormones include T3, T4 and TSH (a hormone responsible for regulating the production of T4 and T3). When your thyroid gland produces too little or too much hormones, it can lead to troublesome symptoms like irritability, fatigue, weight loss, and weight gain. Therefore, it is crucial to ensure that your thyroid hormone levels are balanced.
You should consider getting a thyroid hormone level screening at one of our clinics in London if you have a family history of thyroid disorders (such as thyroid cancer or autoimmune thyroid diseases like Hashimoto’s thyroiditis or Graves’ disease), have a goiter, are pregnant, are taking certain medications, have undergone radiation therapy to your head, neck, or chest, or are over the age of 60.
Hyperthyroidism (an overactive thyroid) and hypothyroidism (an underactive thyroid) occur when your thyroid gland produces too little or too much thyroxine (T4) and triiodothyronine (T3).
