A fine needle aspiration of the thyroid gland is a procedure to remove thyroid cells for examination. The thyroid is located in front of the trachea (windpipe) at the top of the neck.
Alternative NamesThyroid nodule fine needle aspirate biopsy; Biopsy - thyroid - skinny-needle; Skinny-needle thyroid biopsy
How the test is performedThis test may be done in the health care provider's office or in a hospital. Usually numbing medicine (anesthesia) is not needed because the needle is very thin.
You will lie on your back with a pillow under your shoulders and your neck extended. The biopsy site is cleaned. A thin needle is inserted into the thyroid, and a sample of thyroid cells and fluid are removed. The needle is then taken out.
Pressure will be applied to the biopsy site to stop any bleeding. The site will be covered with a bandage.
How to prepare for the testTell your health care provider if you have drug allergies, bleeding problems, or are pregnant. You should also make sure your health care provider has a current list of all medications you take, including herbal remedies and over-the-counter drugs.
How the test will feelYou may feel a sting as the needle is inserted.
Why the test is performedThis is a test to diagnose thyroid disease or thyroid cancer. It is often used to get information on thyroid lumps that can either be felt by the doctor or seen by ultrasound.
Normal ValuesThe thyroid tissue is normal in structure and the cells appear noncancerous under a microscope.
What abnormal results meanAbnormal results may mean:
The main risk is bleeding into or around the thyroid gland. If bleeding is severe, the windpipe (trachea) may be compressed. This complication is rare.
This is done by extracting cells from the thyroid using a very fine needle. It is usually done under local anaesthetic and then the cells are sent to a cytopathologist to be analysed.

typical size needle used for fine needle aspiration
To acquire a sampling of the cells in a thyroid nodule, an endocrinologist or a radiologist will need to perform a fine needle biopsy. The cells extracted will then be evaluated by a pathologist to determine if the growth is benign or malignant, and if surgery is needed. As for a fine needle biopsy will cause thyroid cancer to metastasize, talk to your doctor.Related Article: How to Prepare for a Needle Biopsy
A procedure called fine-needle aspiration allows the clinician to extract cells directly from the lump for further evaluation.

Fine needle aspiration; with imaging guidance
It could be a malignant thyroid nodule. It needs further investigation, likely with fine needle aspiration cytology (FNAC).
It can be done in a doctor's office, clinic, or hospital
The CPT code for a biopsy of a lymph node by fine needle aspiration (FNA) without image guidance is 10005. This code specifically applies to procedures involving the aspiration of a lymph node using a fine needle technique. If the procedure involves multiple lymph nodes, additional codes may be used to report those separately.
Fine needle aspiration is done with a large-gauge needle.
aspiration biopsy (using a fine needle) and large-core needle biopsy. Either of these may be called a percutaneous needle biopsy. Percutaneous refers to a procedure done through the skin.
