One-Day Thyroid Diagnosis

Our team delivers prompt, personalized and efficient expert management of thyroid conditions. We offer a special care pathway enabling a precise diagnosis to be made within 24 hours following a thyroid fine-needle aspiration (FNA) biopsy.

We are a leading thyroid disease center and a pioneer in the use of two minimally invasive treatments: transaxillary robot-assisted thyroidectomy and thermal ablation.

We are the only center in the greater Paris area to provide diagnosis within 24 hours. The typical wait time ranges from ten to fifteen days.

Thyroid FNA biopsy is a minimally invasive procedure that is generally well-tolerated by patients. It consists in extracting cells from a thyroid nodule, a lymph node or a lump in the neck in order to make a diagnosis.

What thyroid nodule treatments are available at the American Hospital of Paris?

We provide treatment for thyroid nodules whether they are detected by the patient through a self exam, by a doctor during a thyroid palpation, or by chance. In this last scenario, known as thyroid incidentaloma, a nodule is discovered during an imaging exam, such as a CT scan, PET scan or supra-aortic trunk Doppler exam, performed for indications other than thyroid evaluation.

  1. First, the patient comes for a consultation at the American Hospital of Paris.
  2. If necessary, an expert ultrasound is performed in our center. If the patient has already undergone a high-quality ultrasound, there is no need for an additional one, and the FNA biopsy can scheduled.
  3. A specific appointment is made for the thyroid FNA biopsy, which will be performed by an experienced health care provider.
  4. The day of the appointment, the procedure is performed and an on-site cytopathologist with expert thyroid disease knowledge analyzes the specimen contained between glass slides.
  5. The biopsy results are provided and explained to the patient the same day, in person.
  6. Patients can contact their endocrinologist, surgeon or other provider the very next day. By then, the doctor who ordered the biopsy will have received the results.

What happens during a thyroid fine-needle aspiration biopsy?

Step 1: A thyroid ultrasound exam with nodule mapping is performed.

Step 2: The indication for a thyroid FNA biopsy is confirmed and the procedure is performed.

Step 3: The slides containing the specimens are sent to the lab for analysis under a microscope.

Step 4: The biopsy results are provided and explained to the patient the same day, in person.
