http://www.smartgroups.com/message/readmessage.cfm?gid=1423922&messageid=3766 Yes, the CBC shows anemia. A biochemistry panel is the next step to determine the cause of the anemia. If the BUN is elevated then it is secondary to kidney disease. If the panel is normal then it can be from Anemia of Chronic Disease (ie insulinoma, lymphoma, bacteria infection, etc). Adrenal gland disease can also cause anemia from high estrogen levels. Lots of possibilities, but more testing is needed. Hope that helps, Jerry Murray, DVM [Posted in FML issue 4099]
