A bone marrow aspirate may be used to confirm an increase in basophils or significantly high numbers of precursors to the granulocytes. Since basophilia is present in a vast range of clinical conditions, depending on a variety of underlying causes, supplemental signs and symptoms must be investigated for a diagnosis.
MPO negative by light microscopy; granules positive in a speckled pattern by electron microscopy. Myeloid antigens are expressed. Diagnosis of poorly differentiated cases made by electron microscopy. May manifest basophil and mast cell granules by EM. Cytogenetically heterogeneous but frequently associated with Philadelphia chromosome. There is ...
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 ...
For this diagnosis, immature eosinophil (e.g. myeloblast) cell counts in the bone marrow and peripheral blood must be less than 20% and the chromosomal alterations (inv(16)(p13.1q22)) and t(16;16)(p13;q22) as well as other features diagnostic of acute myelogenous leukemia must be absent. The latter diagnostic features include clonal cytogenetic ...
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.
In medicine, granulocytosis is the presence of an increased number of granulocytes in the peripheral blood.Often, the word refers to an increased neutrophil granulocyte count (neutrophilia), but granulocytosis formally refers to the combination of neutrophilia, eosinophilia, and basophilia. [1]
A peripheral blood mononuclear cell (PBMC) is any peripheral blood cell having a round nucleus. [1] These cells consist of lymphocytes (T cells, B cells, NK cells) and monocytes, whereas erythrocytes and platelets have no nuclei, and granulocytes (neutrophils, basophils, and eosinophils) have multi-lobed nuclei.
Eosinopenia is a condition where the number of eosinophils, a type of white blood cell, in circulating blood is lower than normal. [1] Eosinophils are a type of granulocyte and consequently from the same cellular lineage as neutrophils, basophils, and mast cells.
