Fine-needle aspiration biopsies of deep visceral or non-palpable masses

Deep or non-palpable masses are sampled under image guidance, such as CT, ultrasound, or fluoroscopy, and are scheduled through the Department of Radiology. The FNA service should be notified so that Cytology staff can be present to prepare the smears and assess the adequacy of the aspirated material. During regular laboratory operating hours, please call (916) 734-3031. Outside of regular operating hours, please contact the AP Pathologist or Resident on call by contacting the hospital operator.
