Leukopenia (from Greek λευκός (leukos) 'white' and πενία (penia) 'deficiency') is a decrease in the number of leukocytes (WBC). Found in the blood, they are the white blood cells, and are the body's primary defense against an infection. Thus the condition of leukopenia places individuals at increased risk of infection.
For those with severe bone marrow failure, the cumulative incidence of resulting stem cell transplantation or death was greater than 70% by individuals 60 years of age. [13] The incidence of bone marrow failure is triphasic: one peak at two to five years during childhood (due to inherited causes), and two peaks in adulthood, between 20 and 25 ...
A white blood cell differential is a medical laboratory test that provides information about the types and amounts of white blood cells in a person's blood. The test, which is usually ordered as part of a complete blood count (CBC), measures the amounts of the five normal white blood cell types – neutrophils, lymphocytes, monocytes, eosinophils and basophils – as well as abnormal cell ...
An excess of white blood cells is usually due to infection or inflammation. Less commonly, a high white blood cell count could indicate certain blood cancers or bone marrow disorders. The number of leukocytes in the blood is often an indicator of disease, and thus the white blood cell count is an important subset of the complete blood count.
Virtually every cell in the body requires iron in order to function well. Iron is involved in key bodily processes, including the transportation of oxygen in the blood. It also plays a central ...
Aplastic anemia causes a deficiency of all blood cell types: red blood cells, white blood cells, and platelets. [5] [6] It occurs most frequently in people in their teens and twenties but is also common among the elderly. It can be caused by immune disease, or by exposure to chemicals, drugs, or radiation. However, in about half of cases, the ...
This is an incomplete list, which may never be able to satisfy certain standards for completion.. There are many conditions of or affecting the human hematologic system—the biological system that includes plasma, platelets, leukocytes, and erythrocytes, the major components of blood and the bone marrow.
The city’s hated new congestion toll could dangerously delay FDNY response times — meaning the “difference between life and death,” unions repping thousands of Bravest warned Sunday.. The ...
