How to test for Thyroid Function
The thyroid gland is a small, butterfly-shaped gland on the front of the neck. It is responsible for producing hormones that regulate the metabolism throughout the body. Testing for thyroid function is a common medical procedure used to assess the proper functioning of the gland.
Methods of Testing
Testing thyroid function can be done in several ways. These include:
- Blood Tests. Tests such as TSH (thyroid stimulating hormone) are used to check the amount of hormones currently produced by the thyroid gland.
- Ultrasound Scans. This type of scan creates high-frequency sound waves to create a visual image of the thyroid gland.
- CT/MRI Scans. This test uses numerous x-rays to produce detailed images of the thyroid gland.
Patient Preparation
Patients may need to do some preparation prior to testing for thyroid function. Guidelines given by their doctor will depend on their specific circumstance, but can include fasting, taking medications, and avoiding caffeine and/or smoking.
Summary
Testing for thyroid function is a medical procedure used to assess the functioning of the thyroid gland. It involves a variety of methods such as blood tests, ultrasounds, and CT/MRI scans. The patient may be required to do certain preparation in advance of the testing.
