Fine Needle Aspiration

Fine needle aspiration

For FNA, the needle is connected to a 6 mL syringe containing 1 to 2 mL of air, which helps expel the sample onto the slide. For solid lesions, the rapid pecking technique is used to collect cells from the lesion. For liquid or cystic lesions, you can connect the needle to the extension device, and then connect the extension device to a needle of the appropriate size for aspiration. The fluid collected from these lesions can be prepared for cytological evaluation or submitted for culture and sensitivity testing. Prepare slides for cytology in a standard way.
