  2. White blood cell differential - Wikipedia

    en.wikipedia.org/wiki/White_blood_cell_differential

    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 ...

    en.wikipedia.org/wiki/Basophil_activation

    In most cases, a positive skin test is used in identification of allergies, but the activation of basophilic granulocytes with anti-IgE, the expression of the CD63 antigen on the cell surface (plasma membrane) allows identification of the allergen responsible for the hypersensitivity reaction without performing the common scratch test. Only a ...

    Basophils are a type of white blood cell. Basophils are the least common type of granulocyte , representing about 0.5% to 1% of circulating white blood cells . [ 1 ] They are the largest type of granulocyte.

    There are four types of granulocytes (full name polymorphonuclear granulocytes): [3] Basophils; Eosinophils; Neutrophils; Mast cells; Except for the mast cells, their names are derived from their staining characteristics; for example, the most abundant granulocyte is the neutrophil granulocyte, which has neutrally staining cytoplasmic granules.

    It also makes blood vessels more permeable so neutrophils and clotting proteins can get into connective tissue more easily. Heparin is an anticoagulant that inhibits blood clotting and promotes the movement of white blood cells into an area. Basophils can also release chemical signals that attract eosinophils and neutrophils to an infection ...

  7. Wright's stain - Wikipedia

    en.wikipedia.org/wiki/Wright's_stain

    Wright's stain is a hematologic stain that facilitates the differentiation of blood cell types. It is classically a mixture of eosin (red) and methylene blue dyes. It is used primarily to stain peripheral blood smears, urine samples, and bone marrow aspirates, which are examined under a light microscope.

    Basophils: Purple/dark blue nucleus, violet granules Monocyte: Violet nucleus, light blue cytoplasm Bacteria and fungi: Dark blue Cytoplasm, collagen and muscle: Various shades of pink, orange, yellow and blue [11] Spermatozoa: Light blue acrosomal region, dark blue post-acrosomal region [8]

  9. Basophilic - Wikipedia

    en.wikipedia.org/wiki/Basophilic

    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.
