Adequacy is carried out by the Biomedical Scientist usually in the UK. I make a couple of air dried per passage and stain Diff Quick; you can then give an indication of adequacy within 5 min or so. Usually if the FNA is performed properly you don't get much material;; for example breast and LN's are usually sparse and you get maybe a couple of slides (we don't check these for adequacy as the Site is easily re-needled). Pancreas, Thyroid and Lung are another matter. Usually CT orientated FNAC of the lung tend not to be too cellular but sometimes they are; I used to stain a couple for adequacy and make as many slides as possible. The problem is if you make loads of slides and malignant cells are not apparent in those you stain then you have to look at all the others; tough. If there are malignant cells abundant then you ought to look at all the slides just in case they hold diagnostic information. In the end we did 6 slides and washed the remainder into a pot with saline and did Cytospins if appropriate.
Pancreatic FNACs taken under a ultra sound flexible scope can also be very cellular (blood) and the above statement holds. Thyroid's can be very bloody, very bloody; trick is not to pull on the plunger but let it seep into the syringe. Too much blood and what little you have gets well diluted!!

Moose Sent: 31 August 2009 19:34 To: histonet@lists.utsouthwestern.edu Subject: [Histonet] FNA SLIDES A question has arisen for us- How many slides do you (should you) make per pass for pathologist for adequacy and/or diagnosis? What about CT guided biopsies of liver, lung, "masses" etc. Thanks in advance for your input.
