How Do I Prepare and What Can I Expect 

Ultrasound-Guided Thyroid Biopsy
An ultrasound-guided thyroid biopsy is a procedure that is performed to evaluate lumps or nodules in your thyroid gland that have been detected either by a physical exam or a prior ultrasound. Tiny samples of thyroid tissue are removed for evaluation and testing. The procedure takes approximately thirty minutes to complete.  

How to Prepare for an Ultrasound-Guided Thyroid Biopsy

  • Eat a regular meal prior to arrival.
  • Bring a list of medications you usually take and any allergies you have.
  • Take your regular medications with sips of water.   Prior to your procedure, please check with your physician for restrictions regarding medications that may increase bleeding, such as Aspirin, Coumadin, Plavix, Ibuprofen, Motrin, Naprosyn, Vitamin E, Ginko Biloba, Garlic supplements, Glucosamine Chondroiton, Flaxseed, Fish Oil, Feverfew, Ginger, Licorice.

  • The bandaid on the biopsy site should be left on for one day.
