My cat's healthy but has a high white blood cell count. Why?

If Pudding has been normal and the veterinarian did not find any abnormalities on her physical exam, then try not to stress. The blood cells are cyclic in nature and sometimes we catch them at a low point. Stress can also impact the counts. Retesting in 3 weeks is the best route to go so that you can see what the trend is and then make an appropriate assessment. I hope this helps and please feel free to post any additional questions.

It can be indicative of an immune problem, but can occur for various other reasons. I would have it checked again in a few weeks in case it was just transient, also confirming a low wbc count on a microscope is a good idea as machines can get it wrong. Maybe your vet already did this though.

Hi there! If your cat is clinically normal (not having any symptoms of a problem), this likely is not a problem and doesn't mean anything at all. Some animals may have RBC counts that are slightly out of the normal "average" ranges on lab work. Unless there are symptoms of a problem that can be correlated with these changes, they're not usually anything to worry about.

Hello, the elevations of the cells is very mild. It appears that she may have a mild infection, given that his eosinophils are high, the most likely cause may be associated with parasites. The medications should not cause the white blood cells to go up, instead, it should help decrease their number. Speak with your veterinarian about checking his stool for parasites and consider deworming him as well. Also check for heart worm disease. Hope this helps and best of luck.

High white cell counts indicate inflammation or infection and yes, IBD can contribute. IF she seems back to herself you could continue with the new diet and retest in 3-4weeks to see if the white count is returning to normal. Intestinal biopsies are not without risk and if she has stabilised on the new diet I would be include to continue and monitor

This is only a CBC test result. The white count is low and it is mostly low from not enough lymphocytes. My suspicion would be a virus or cancer. Viral infections are the most common cause of a low white blood cell count in cats. Feline Immunodeficiency Virus (FIV) and Feline Infectious Peritonitis (FIP) are two such viruses. These viruses invade the white blood cells and use them to make copies of themselves, increasing the virus’ strength and reducing the number of white blood cells. Other possibilities include: * Bacterial infections. These infections can range from abscesses to respiratory infections to sepsis. Essentially, any infection or inflammation causes a drop in white blood cells, particularly neutrophils. HER DROP IS LYMPHOCYTES, not neutrophils so I think this is less likely. * Bone marrow diseases, or the panleukopenia virus, which destroys the marrow where white blood cells are produced. * Pancreatitis. The inflammation of the pancreas will draw white blood cells from the bloodstream, lowering their count. * Certain medications. Corticosteroids can actually suppress the production of white blood cells. THIS IS WHY I DON'T AGREE WITH THE STEROID ADMINISTRATION AT THIS TIME. Antibiotics, yes. Steroids, no. Just my opinion though. I can't really say your vet is wrong. This is just not what I would do especially since she is not responding. More testing needs to be done: * repeat the CBC to see where the white count is now * chemistry panel to check liver, kidneys, etc * FeLV/FIV testing * FIP (corona virus) testing * pancreatitis test Hope this helps. Best wishes.

My concerns are that Kim has a high white blood count (indicating possible infection or immune mediated infection) and REALLY low hematocrit of 12%. The hematocrit is the percentage of red blood cells in the body. Usually when it is that low, the animal needs a blood transfusion. Granted I didn't do the exam on him so I would call your vet to discuss if this is needed, as well as additional diagnostics or medicines. I would also talk to them about whethe he needs to be hospitalized in a 24 hour care until he is more stable as he sounds very sick. I hope this helps and he starts to feel better really soon.
