Thyroid Test - what is it and how the test is done
Our body contains several important endocrine glands that help regulate its metabolism and other functions that are required for us to function properly. The thyroid gland is one of such principal glands without which several functions of our body will stop taking place normally. In case your doctor suspects that your thyroid gland is not functioning properly, they will right away order a blood test that will determine: - the functioning of your thyroid gland and if it is working normally, - the levels of thyroid hormone (T3 and T4) in the blood, and - whether you have hypothyroidism or hyperthyroidism, based on low or high levels of these hormones, respectively. A thyroid function test is a simple blood test, where blood is drawn from your arm and then sent to the lab for analysis. However, with these thyroid function test evaluations, it becomes easier to order a targeted treatment plan that will help bring back your thyroid gland functioning back to normal and will enable the circulating thyroid hormones to remain within their normal ranges, thus ensuring a perfectly well-balanced metabolism of your body.
