Collection Instructions
1 mL node washing or saline node washing is also acceptable. A 25-gauge needle is inserted obliquely within the transducer plane of view and moved back and forth through the nodule to compensate for patient movement and needle deflection. There is no suction device; cells move into the needle via capillary action. Three to six separate passes are performed, each with a new needle. After collection of the cytology samples, each FNA needle is then washed with 0.1-0.5 mL of normal saline; the washes from all needles are pooled (final volume 1 mL) and immediately frozen. and then transported to the laboratory directly.
