Can I ask you all, what do you use as controls when doing ICC on cytology
cytospin preps or smears?  Since there isn't much sample, do you use
paraffin sections as positive controls and is that adequate control

thin layer cytology preps and wondering what control material to use.
Thanks for your help.
