Fine Needle Aspiration

Fine Needle Aspiration is a minimally invasive procedure. The needles used in this procedure are thinner than those used for blood drawing. Because of the ultrasound guided aspiration techniques, both palpable and nonpalpable lesions can be assessed. Fine needle aspiration collects cells from superficial lesions of the thyroid nodules, lymph nodes, salivary gland, soft tissue and breast. It is a very safe, minor surgical diagnostic procedure and takes less than a few minutes.

The advantages of a pathologist performing FNA’s:

  • FNA’s are done onsite and can be immediately assessed for adequacy of the specimen.
  • Immediate preliminary diagnosis.
  • Depending on the results of the immediate evaluation, additional specimens can be collected for special studies such as culture, flow cytometry and immunohistochemical staining.
  • Results are usually provided within 24 hours.
