WE would like to update guidelines for specimen submission to our Cytopathology dept. and we are interested to know requirements of other labs for pleural effusion samples - do they require the whole volume of effusion? or only a part of it? 150 ml or up to 500 ml? the first part or the last part? what kind of sampling do they recommend in a case of large volume effusions?
thanks for any input
