How do they check your thyroid? Understanding the process of thyroid examination is crucial for individuals who have concerns about their thyroid health or have been diagnosed with a thyroid condition. The thyroid, a small gland located at the base of the neck, plays a vital role in regulating metabolism, energy levels, and overall health. Detecting thyroid disorders early is essential for effective management and treatment. This article will explore the various methods used to check the thyroid and what you can expect during these examinations.
One of the most common and straightforward ways to check your thyroid is through a physical examination. A healthcare provider will feel your thyroid gland by pressing gently on your neck to assess its size, shape, and texture. This examination can help identify any abnormalities, such as swelling or nodules, which may indicate a thyroid disorder. While this method is not definitive, it can often provide valuable clues and prompt further investigation.
Ultrasound is another diagnostic tool used to check the thyroid. An ultrasound uses high-frequency sound waves to create images of the thyroid gland. This non-invasive procedure is painless and can help identify nodules, cysts, or other abnormalities that may not be palpable during a physical examination. It can also provide information about the size, shape, and characteristics of the thyroid gland, which can be helpful in diagnosing conditions such as thyroiditis or thyroid cancer.
Thyroid function tests are blood tests that measure the levels of thyroid hormones in the body. These tests can help determine if the thyroid is overactive (hyperthyroidism) or underactive (hypothyroidism). The most common thyroid function tests include:

Radioactive iodine uptake (RAIU) is another diagnostic test used to check the thyroid. This test involves swallowing a small amount of radioactive iodine, which is then absorbed by the thyroid gland. The levels of radioactive iodine in the blood and thyroid gland are measured over time to assess the gland’s function. RAIU can help diagnose hyperthyroidism, hypothyroidism, and thyroiditis.
In some cases, a fine-needle aspiration biopsy (FNAB) may be necessary to check the thyroid. This procedure involves using a thin needle to extract a small tissue sample from the thyroid gland. The sample is then examined under a microscope to look for signs of cancer or other abnormalities. FNAB is typically recommended when a nodule is found on the thyroid gland and further investigation is needed.
Understanding how they check your thyroid can help you feel more prepared and informed about your thyroid health. If you have concerns about your thyroid, it’s essential to consult with a healthcare provider who can guide you through the appropriate diagnostic tests and treatment options.
