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 ...
In hematology, plasma cell dyscrasias (also termed plasma cell disorders and plasma cell proliferative diseases) are a spectrum of progressively more severe monoclonal gammopathies in which a clone or multiple clones of pre-malignant or malignant plasma cells (sometimes in association with lymphoplasmacytoid cells or B lymphocytes) over-produce and secrete into the blood stream a myeloma ...
Postoperative cognitive dysfunction (POCD) is a decline in cognitive function (especially in memory and executive functions) that may last from 1–12 months after surgery, or longer. [1] In some cases, this disorder may persist for several years after major surgery. [2] POCD is distinct from emergence delirium. Its causes are under ...
Monocytopenia is a form of leukopenia associated with a deficiency of monocytes. It has been proposed as a measure during chemotherapy to predict neutropenia , [ 1 ] though some research indicates that it is less effective than lymphopenia .
Non-classical monocytes produce high amounts of pro-inflammatory cytokines like tumor necrosis factor and interleukin-12 after stimulation with microbial products. Furthermore, a monocyte patrolling behavior has been demonstrated in humans both for the classical and the non-classical monocytes, meaning that they slowly move along the ...
Leukocytosis can be subcategorized by the type of white blood cell that is increased in number. Leukocytosis in which neutrophils are elevated is neutrophilia; leukocytosis in which lymphocyte count is elevated is lymphocytosis; leukocytosis in which monocyte count is elevated is monocytosis; and leukocytosis in which eosinophil count is elevated is eosinophilia.
With a high rate of Ras mutation in CMML, deregulation of this signalling pathway has been linked to the pathogenesis of the disease. Tumour necrosis factor, GM-CSF, interleukin-3, interleukin-4, interleukin-6, and interleukin-10 may have a role in hyperproliferative CMML cells. These cytokines can stimulate the growth of CMML in vitro. [11]
Acute myelomonocytic leukemia (AMML) is a form of acute myeloid leukemia that involves a proliferation of CFU-GM myeloblasts and monoblasts.AMML occurs with a rapid increase amount in white blood cell count and is defined by more than 20% of myeloblast in the bone marrow.
