What is the purpose of a follow up examination for a cat?
Your veterinarian will schedule follow-up examinations for your cat to monitor eosinophil counts (not always indicative of tissue infiltrates) and myelosuppression (by which bone marrow activity is decreased) if chemotherapeutic drugs are being used . Clinical signs will also be monitored along with any physical abnormalities (e.g. loss of appetite, lethargy, vomiting, and diarrhea).
What organs are affected by eosinophils?
Common sites of infiltration include the gastrointestinal tract (especially the intestine and liver), spleen, bone marrow, lungs, and lymph nodes (especial ly those in the abdominal area). It frequently has a fatal outcome.
What is the inflammatory disease of the small intestine?
An early form of this disorder may be apparent in some cats; eosinophilic enteritis, an inflammatory disease of the small intestine that is directly related to infiltration of eosinophils in the connective tissue of the intestinal lining.
What is the disorder of cats?
Hypereosinophilic Syndrome in Cats. Hypereosinophilic syndrome, characterized by persistent eosinophilia -- that is, sustained overproduction of eosinophils (white blood cells of the immune system) in the bone marrow, is a disorder of unknown cause.
What is the purpose of radiographic contrast?
Radiographic contrast, which uses an injection of a radiocontrasting agent into the area to be viewed, may be used to improve visibility of the internal organs . These X-rays may show thickened intestines and abnormalities in the lining of the intestines. Other findings may be reactive hyperplasia (abnormal enlargement) of the lymph nodes due to eosinophil infiltration, and fibrosis (excess fibrous connective tissue) and thrombosis (coagulation in the arteries) surrounding the heart.

Other findings may be reactive hyperplasia (abnormal enlargement) of the lymph nodes due to eosinophil infiltration, and fibrosis (excess fibrous connective tissue) and thrombosis (coagulation in the arteries) surrounding the heart.
What does a high WBC mean?
Generally a high white blood cell count means that Muffin has an infection or virus. However, the WBC is just one piece of the diagnostic puzzle. The rest of the blood work, such as platelets and red blood cell count, must be considered. The vet will also have to account for Muffin's medical history, her symptoms and her lifestyle.
What are the different types of white blood cells?
There are five types of white blood cells: neutrophils, eosinophils, monocytes, lymphocytes and basophils, all known as the differential. The distribution of these cells can help focus on the cause of an illness. Neutrophils are the primary white blood cells that fight infection, so if Muffin's neutrophil level is high, she's likely got an infection. Since monocytes help in this battle, a high level of monocytes indicate the same condition. Lymphocytes also help fight infection as well as develop antibodies to ward off future attacks. High levels of these cells indicate infection, viral diseases and certain forms of cancer. Eosinophils are often elevated when a cat has parasites or an allergic reaction. Basophils aren't very common and tend to appear in cases of parasite infection, particularly in animals with heartworm.
What is the normal range for a cat's WBC?
White blood cells are measured as thousands per cubic milliliter (K/uL). The normal range in a cat is between 5.5 and 19.5, meaning under normal conditions Muffin should have ...
What is the primary white blood cell that fights infection?
Neutrophils are the primary white blood cells that fight infection, so if Muffin's neutrophil level is high, she's likely got an infection. Since monocytes help in this battle, a high level of monocytes indicate the same condition. Lymphocytes also help fight infection as well as develop antibodies to ward off future attacks.

The normal range in a cat is between 5.5 and 19.5 , meaning under normal conditions Muffin should have between 5,500 and 19,500 white blood cells per cubic milliliter of blood. Low WBCs can indicate viral infections, bone marrow issues or poisoning; in these cases, the white blood cells are concentrated in the affected area ...
Why are lymphocytes important for cats?
Lymphocytes also help fight infection as well as develop antibodies to ward off future attacks. High levels of these cells indicate infection, viral diseases and certain forms of cancer. Eosinophils are often elevated when a cat has parasites or an allergic reaction.
What does WBC mean in cats?
The white blood cell count (WBC) is a valuable diagnostic tool. Along with other tests, medical history and symptoms, it reveals a lot about the state of a cat's health. If Muffin's older or feeling punky, chances are her vet will use this indicator to help gauge her health.
What is the difference between natural killer cells and T cells?
Natural killer cells and some types of T cells (cytotoxic T cells, for example) destroy foreign material, whereas antibodies and other T cells (helper T cells) stimulate other parts of the immune system to do so. If lymphocytes are reduced or abnormal, the cat is immunodeficient and susceptible to a wide variety of infections.
Why do neutrophils increase in the presence of inflammation?
Because of this, the number of phagocytes in the blood can provide an indication of circumstances in the tissues. For example, the neutrophil number increases in the presence of inflammation. An abnormally low number of circulating neutrophils (due to marrow failure, drugs, or toxins) can lower resistance to bacterial infections.
Why do lymphocytes act as a response?
Lymphocytes usually act appropriately to rid the body of foreign “invaders” that cause disease. An inappropriate response occurs when antibodies are produced against the body’s own cells, such as red blood cells.
What hormones cause lymphocytosis?
Lymphocytosis, an increase in the number of circulating lymphocytes, may occur as a response to the secretion of epinephrine (a hormone also known as adrenaline). A reduction in the number of lymphocytes circulating in the blood may be caused by corticosteroid drugs or hormones secreted during times of stress.
How are phagocytes regulated?
As with red blood cells, the production and number of phagocytes are tightly regulated by chemical messengers of the blood. Unlike red blood cells, which remain circulating in the blood, phagocytes use blood vessels as a pathway to the tissues. Because of this, the number of phagocytes in the blood can provide an indication ...
What is the name of the antibody that is produced in response to a new microorganism?
They include several classes, each of which has a different function. For example, one class (IgA) is commonly found in the lungs and intestines; another (IgM) is the first antibody produced in response to newly recognized foreign microorganisms; a third (IgG) is the main antibody in the bloodstream; and a fourth (IgE) is involved in allergic reactions.
What is the function of white blood cells?
The function of white blood cells (also called leukocytes) is to defend the body against infection. There are 2 main types of white blood cells: phagocytes and lymphocytes.
Why is WBC low?
With that known, any count of WBC deviating from the normal reference range for a human being is dangerous. An elevated count of WBC might be a sign of an ongoing infection which stimulated the body to raise its army of WBC abruptly. SImilarly, low counts of White Blood Cells could result due to weak immune functioning, malnutrition or other medical issues. It equally could be due to an infection that has already progressed and is silently destroying the WBC’s. There could be low or non-significant symptoms in some cases and the disease can only be detected later. However, In both the cases, the human body is prone to deadly diseases.
What is the function of white blood cells?
White blood cells or WBC are groups of nucleated cells (unlike non-nucleated mature RBC) having different shapes, sizes and possess selective functions; very crucial for our body immunity against the outer pathogens such as bacteria, parasites, viruses etc. The WBC are also responsible for cleaning the old ageing cells, cancer causing cells and cellular debris produced by cell lysis or inflammation. However, the number of WBC are less than RBC but their function is very crucial for a healthy body. Decrease in number of WBC may lead to multiple health complications caused by weak immun
What is an elevated WBC count?
Some moderately elevated counts may show a large number of immature forms of white blood cells and this can also be consistent with a malignancy or severe infection. So basically an elevated WBC count or the presence of an abnormal percentage of immature WBCs in an otherwise asymptomatic patient is an indication for further evaluation. The most likely next test would be a bone marrow aspiration and biopsy which is a relatively minor procedure when done skillfully. Using an amnestic drug like Versed can shield a patient from any memory of the procedure and a local anesthetic along with an intravenous analgesic can virtually eliminate any pain. I performed many of these using only a local anesthetic and patients tolerated the procedure with only very brief and and relatively minor pain. So I wouldn't be fearful of the test if it is recommended.
Why are white blood cells important?
They are crucial and deciding to survival of a human being, because without them the human body is prone to infinite infections and diseases. WBC works alongside other immune mechanism to defy the body against such infections, and their number is determining to a person’s immune resistance. There are different types of WBC’s in body and each have their own normal counts.
What happens if you have a high neutrophil count?
If the differential count has more neutrophils in it then lymphocytes (and I'm talking a high amount of neutrophils, like over 65%) then you would more than likely have a bacteria infection.
What does it mean when a cat's white blood cell count is high?
I'm assuming it could mean there is some sort of infection, just like with humans. White blood cells all react in the same way within the animal kingdom. They all have the same purpose. If the white blood cell count on a cat is high (whatever would be considered high for a cat), I would assume infection. Let the vet inform you of what kind of infection before trying to administer antibiotics on your own though.
What does a lab pathologist look for in a vet?
The lab pathologist and your vet look at both ABS and percentages to make their diagnosis. Normally, the percentages are stable within each group.
What type of cells secrete antibodies?
Lymphocytes. Granulocytes. Monocytes. There are two types of lymphocytes – B and T cells. B-lymphocytes secrete antibodies, special proteins that bind to foreign organisms in the body to help destroy them. Think of antibodies as special blood soldiers charged with assassinating foreign invaders.
Why is CBC not performed in primary care?
Despite this fact and in my experience, this recommended component is often not performed in primary care veterinary practices. Two most commonly cited reasons from primary care doctors for omitting a blood film evaluation are lack of confidence performing a blood film assessment and lack of time to perform the evaluation. In contrast, veterinary reference laboratories are not allowed to omit this step! If veterinary reference laboratories can’t omit peripheral blood film evaluations, then veterinarians performing CBCs in their in-house laboratories can’t omit them either!
What is a complete blood count?
Measuring WBCs is relatively straightforward. A small sample of blood is collected for a non-invasive test called a complete blood count (CBC). A CBC allows a veterinarian to obtain a comprehensive evaluation of blood, as it measures WBCs, as well as RBCs, blood clot-forming cells called platelets. Complete blood counts are performed on machines called hematology analyzers found either at reference veterinary laboratories or in hospitals. There are advantages and potential limitations to performing tests in a veterinary hospital compared to a reference veterinary laboratory. To learn more about this, click here.
What are the most common white blood cells?
Granulocytes are the most common type of white blood cells in circulation. These cells contain many granules filled with potent chemicals involved in immune responses. They help the body get rid of certain types of infectious organisms, and are also involved in inflammatory processes and allergic reactions. On the basis of how their granules take ...
What do monocytes do?
Monocytes travel from blood vessels to sites of infection to become macrophages that scavenge that phagocytosed organisms and cleanup of cellular debris. Some macrophages also aid T-lymphocytes in their immunologic responsibilities.
What are the cells that protect the body?
White blood cells, also called leukocytes, are cells that defend the body against various diseases, including infectious organisms (i.e.: bacteria, virus, fungi, protozoa, etc.) and cancer. An elevated white blood cell count (called leukocytosis) can happen for a number of reasons, including: 1 Increased production to fight an infection 2 Reaction to a drug that increases production 3 A bone marrow disorder that causes increased production 4 A disorder of the immune system that increases production
What causes increased production of WBCs?
Increased production to fight an infection. Reaction to a drug that increases production. A bone marrow disorder that causes increased production. A disorder of the immune system that increases production. White blood cells or WBCs are made in the bone marrow, are released into circulation, and ultimately travel to various tissues ...
What Is Anemia?
Anemia is a term that means a decrease in red blood cells (RBCs), which may be mild, moderate, or severe. It’s caused by an underlying disease, injury, infection, or toxin.
How does anemia in cats come about?
Anemia in cats may come about in three ways: by blood loss, by a problem with RBC production, or by conditions in which RBCs are destroyed. Sometimes, more than one of these factors is involved.
Why is it bad for cats to go outside?
Also, going outdoors puts cats at an increased risk of anemia due to trauma/injuries, parasites, and infections.
What does looking at a blood smear under a microscope tell you?
Looking at a blood smear under a microscope also provides information about RBC size and appearance (which helps determine if the anemia is regenerative or non-regenerative) and allows visualization of blood cell parasites.
What is the term for a decrease in the body's circulating red blood cells?
Anemia is the term for a decrease in the body’s circulating red blood cells (RBCs). Depending how low the RBC count goes, this may cause anything from mild symptoms to a life-threatening emergency.
How long do RBCs live?
RBCs only live for about two months, so the body regularly produces a new supply. The demand for new red blood cells is even higher during anemia.
What does anemia mean in cats?
Anemia causes a wide variety of symptoms. The pictured cat shows signs of jaundice, which occurs in very severe cases of anemia. Usually, this is only seen with sudden rupture (hemolysis) of large numbers of RBCs.
Symptoms
Causes
- The cause of hypereosinophilic syndrome is unknown. However, it is believed to be cause by a severe reaction to an underlying, as yet unidentifiable antigenic stimulus that may be composed of two different strains of a virus. An early form of this disorder may be apparent in some cats; eosinophilic enteritis, an inflammatory disease of the small in...
Diagnosis
- The veterinary examination will consist of standard laboratory work, including a complete blood profile, chemical blood profile, a complete blood count, and a urinalysis. You will need to give a thorough history of your cat's health and onset of symptoms. Additional diagnostics will include a bone marrow aspiration and/or core biopsy of the cells, and a biopsy of the affected organ or m…
Treatment
- Long-term maintenance therapy will be employed to control or reduce the eosinophilia and organ damage. High serum immunoglobulin concentrations (the fraction of the blood serum that contains antibodies) can signify a good response to treatment with prednisone, a corticosteroid given to reduce inflammation, and therefore a better prognosis. Prednisone can be effective at s…
Living and Management
- Your veterinarian will schedule follow-up examinations for your cat to monitor eosinophil counts (not always indicative of tissue infiltrates) and myelosuppression (by which bone marrow activity is decreased) if chemotherapeutic drugs are being used. Clinical signs will also be monitored along with any physical abnormalities (e.g. loss of appetite, lethargy, vomiting, and diarrhea).
