- White blood cell disorders occur when you have too many or too few white blood cells. White blood cells, also known as leukocytes, are one of three types of cells that compose the blood. They are produced in the bone marrow and play an important role in your immune system.

Hypogranularity refers to a decrease in the number and/or staining intensity of granules within the cytoplasm of white blood cells (WBCs). This abnormality can be observed in various types of WBCs, including neutrophils, eosinophils, and basophils.
Definition. White blood cells (WBC) are a heterogeneous group of nucleated cells that can be found in circulation for at least a period of their life. Their normal concentration in blood varies between 4000 and 10,000 per microliter.

White blood cells are also known as leukocytes. They are the body's defense against infections. There are several different types with different purposes. Some white blood cells are part of our innate immune system, meaning they know how to attack foreigners from the moment we’re born. Other white blood cells are part of our humoral or learned immu...
White blood cells start out in the bone marrow in a process called hematopoiesis. All blood cells come from a common hematopoietic stem cell (HSC). This is also called a "pluripotent" stem cell. These stem cells specialize—or differentiate—in different stages. The HSC cell first separates into either a lymphoid or myeloid stem cell. The lymphoid st...
A low WBC count does not have symptoms on its own, but having low WBCs can make you more likely to get an infection. Common symptoms of infections include: 1. Fever 2. Cough 3. Painful or frequent urination 4. Blood in the stools 5. Diarrhea 6. Redness, swelling, or warmth near the infection
Leukocytosis means ahigh white blood cell count. Infections usually cause a higher-than-normal (elevated) white blood cell count, but there are also other causes of high WBCs. WBC counts can also be increased when the body releases white blood cells too early from the bone marrow (overproduction). Common causes of elevated WBCs include: 1. Infectio...
Leukopenia means a low white blood cell count.A low white blood cell countcan be caused by: 1. Severe infections 2. Bone marrow damage or disorders (e.g., aplastic anemia, bone marrow "takeover" by blood cancers or metastatic cancer; drug or chemical-related damage to the bone marrow) 3. Autoimmune diseases (e.g., lupus, rheumatoid arthritis) 4. Sp...
White blood cells are an important part of our immune system. Different types of white blood cells perform different functions in the body. Overall, white blood cells help to protect us against bacteria, viruses, and parasites. A high white blood cell countis usually a sign of an infection or illness. A low white blood cell count can indicate anoth...
Oct 15, 2023 · A white blood cell disorder is one in which the white blood cells are either qualitatively or quantitatively affected. There are many possible causes of this, including infections, genetic disorders, autoimmune diseases, and, in rare cases, cancer.
White blood cell (WBC) count measures the total number of white blood cells per volume of blood. Both increases and decreases can be significant.
