Preferred Specimen
Needle washings in alcohol-based preservative (e.g. CytoLyt®), collected in a plastic leak-proof container and
4 unstained, fixed or air-dried slides of needle washings, submitted in a slide container
4 unstained, fixed or air-dried slides of needle washings, submitted in a slide container
Instructions
DO NOT REJECT.
Express a small portion of the FNA from needle directly onto glass slide and air dry or fix immediately by immersing in alcohol or by fixing with a commercially prepared cytology spray fixative. Label each slide with patient's name, pathology sample ID, and the number of needle pass (i.e., 1 for 1st, 2 for 2nd, etc). The needle should then be washed in a screw-cap vial of alcohol-based fixative (e.g. CytoLyt®) and labeled with patient's name, pathology sample ID and FNA location. FNAs from different locations (e.g., distinct nodules) should be collected individually on different slides and needle washings (e.g., A-left lobe, B-right lobe).

Clinical Significance
Thyroid masses are evaluated by fine needle aspiration (FNA). This assay will provide cytologic evaluation and diagnosis of thyroid FNAs by a cytopathologist.
