In an attempt to reduce the number of inadequate smears processed by our laboratory and the false negative rate of fine needle aspiration cytodiagnosis, we have introduced a fine needle aspiration cytology service where aspirates are taken by the cytopathologist in a clinic. In the 12 month period since the introduction of this service, the number of inadequate smears fell sharply. Nine per cent of the specimens were inadequate compared with 43% of specimens from other sources. the establishment of the clinic resulted in a threefold reduction in the cost of diagnosing breast lesions.
