It all depends on your definition of "levels" . Levels is going deeper into the block between each pick up. Serial sections are just cutting a ribbon and taking that ribbon. I don't feel you are deeper in the block when you take "sections" at 12 and 13. Sections 19 and 20 may be deep enough to be considered "level 2". You are only advancing 3um with each section. It doesn't do the patient any good to leave the tissue undiagnosed in the block. There have been times when the cancer didn't show up until level 3. I treat every biopsy as my own. Of course, you must defer to the pathologist . Our job is not to make it easier on us, ours is to serve the patient. Just my 2 cents.
