The root cause of basophilia can be determined through a bone marrow biopsy, genetic testing to look for genetic mutations, or ultrasound to determine enlargement of the spleen. 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 ...
A Basophil granulocyte stains dark purple upon H&E staining. Basophilic is a technical term used by pathologists. It describes the appearance of cells, tissues and cellular structures as seen through the microscope after a histological section has been stained with a basic dye. The most common such dye is haematoxylin.
An anterior pituitary basophil is a type of cell in the anterior pituitary which manufactures hormones. It is called a basophil because it is basophilic (readily takes up bases), and typically stains a relatively deep blue or purple. [1] These basophils are further classified by the hormones they produce.
Reference ranges for blood tests of white blood cells, comparing basophil amount (shown in violet) with other cells. Basophils appear in many specific kinds of inflammatory reactions, particularly those that cause allergic symptoms. Basophils contain anticoagulant heparin, [8] which prevents blood from
When an infection occurs, mature basophils will be released from the bone marrow and travel to the site of infection. [24] When basophils are injured, they will release histamine, which contributes to the inflammatory response that helps fight invading organisms. Histamine causes dilation and increased permeability of capillaries close to the ...
Allergic symptoms are caused by an initial systemic histamine release by activated basophils and mast cells, that may lead to shock with laryngeal edema, lower-airway obstruction and hypotension. This is why basophils are considered with mast cells to be the key cells in allergic diseases. basophil activation and labeling
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 ...
Basopenia (or basocytopenia) is a form of agranulocytosis associated with a deficiency of basophils. [1] It has been proposed as an indicator of ovulation. [2] It is difficult to detect without flow cytometry, because normal levels are so low. [3]
