Fine Needle Aspiration Service
The cytology service offers an FNA clinic where we perform fine needle aspiration biopsies on superficial nodules. Portable ultrasound imaging is used selectively for non-palpable nodules. The clinic is open to both Stanford patients and patients from off-site clinics. Clinic hours are from 9 a.m. until 4 p.m., Monday through Friday.
The clinic operates as a walk-in service (i.e. first come first serve) with no appointments necessary. Early arrival is encouraged to minimize waiting, as wait times vary widely and may be in excess of 3 hours or more.
Patients are required to have a written FNA order specifying the biopsy site (include indication if site is palpable or if ultrasound will be required), clinical history, any requests for special studies (e.g. flow cytometry, specific molecular assays), ordering physician's name and contact information, and an ICD code. If the patient is not registered at Stanford, patient demographics and insurance information will also be required for pre-registration, which will need to be completed before the patient is seen.
