Definition:

The thyroid is an endocrine gland located in front of the trachea (windpipe) at the top of the neck. In fine needle aspiration, a needle is inserted into the thyroid to obtain a sample of thyroid cells.

Alternative Names:

How the test is performed:

This test may be done in the health care provider's office or in a hospital. Usually anesthesia is not necessary because the needle is fine (very thin). You will lie on your back with a pillow under your shoulders and your neck extended.

The biopsy site is cleansed. The fine needle is then inserted into the thyroid, and a sample of thyroid cells and fluid is drawn into the needle. The needle is then withdrawn.

Pressure will be applied to the biopsy site to stop any bleeding, and the site will be covered with a bandage.

How to prepare for the test:

Inform the health care provider of any drug allergies you have, which medications you are taking, if you have bleeding problems, and if you are pregnant. You must sign a consent form.

For infants and children:

The preparation you can provide for this procedure depends on your child's age and experience. For specific information regarding how you can prepare your child, see the following topics:
