Thyroid Exam The thyroid exam is important as it's often the first step towards diagnosing thyroid diseases such as Grave's disease, Hashimoto's thyroiditis and multinodular goiters. Both inspection and palpation are important aspects of the thyroid exam. Anatomy of the Thyroid Techniques: Thryroid Exam There are several physical examination maneuvers described for examination of the thyroid described below that are at least moderately sensitive and specific. Much of the exam is based on physiological reasoning and tradition rather than on studies of reliability or precision Introduction: Examination of Thyroid Thyroid disease, the second most prevalent endocrine disorder, occurs in 10 to 15% of the population over age 40. The overall prevalence of overt hypothyroidism is approximately 1 to 3%, rising as high as 10% in women. Most cases of hypothyroidism present after the age of 50 The best way to initially test thyroid function is to measure the TSH level in a blood sample. Changes in TSH can serve as an early warning system - often occurring before the actual level of thyroid hormones in the body becomes too high or too low

There are certain signs and symptoms that the patient may present with and it is these that you are examining the patient for in this station The thyroid is an endocrine gland located in the neck. It secretes hormones that are responsible for metabolic rate, protein synthesis, and the body's sensitivities to other hormones. In this article, we shall look at how to perform an examination of the thyroid gland, and detect signs of thyroid disease
A thyroid scan is usually ordered when a physical examination or laboratory finding suggests that the thyroid is enlarged or has a lump (called a thyroid nodule). If laboratory tests show an overactive thyroid, a radioactive iodine uptake test may be ordered at the same time to evaluate thyroid function The specific blood tests that will be done to test your thyroid can include: Thyroid-stimulating hormone (TSH) is produced in the pituitary gland and regulates the balance of thyroid hormones — including T4 and T3 — in the bloodstream. This is usually the first test your provider will do to check for thyroid hormone imbalance
When abnormal thyroid function tests are not due to thyroid disease. While blood tests to measure thyroid hormones and thyroid stimulating hormone (TSH) are widely available, it is important to remember that no all tests are useful in all circumstances and many factors including medications, supplements, and non-thyroid medical conditions can affect thyroid test results Thyroid Uptake & Scan This nuclear medicine exam is performed to evaluate the size, location, and overall functional level of the thyroid gland.
