We are seeing rouleaux fairly frequently that appears in one screen cell and not the other, and in some of the gel panel cells the same way. This is in a Ortho IgG gel card ran on a Vision analyzer. The Rouleaux is verified in tube under the scope. We normally run a PEG tube screen and panel on these patient's and they are almost always negative. Why would this appear in some cells and not in others?
Thank you.
