Fine Needle Aspiration is a technique, whereby cells are obtained from a lesion or organ using a thin needle. Aspirated material is smeared, stained and examined under a microscope for diagnosis or used for molecular biology, cytometry or in vitro analysis. It is cheap, simple, quick and causes minimal trauma.
