  2. Blood smear - Wikipedia

    en.wikipedia.org/wiki/Blood_smear

    Modern complete blood count analyzers can provide an automated white blood cell differential, but they have a limited ability to differentiate immature and abnormal cells, so manual examination of the blood smear is frequently indicated. [5] [6] Blood smear examination is the preferred diagnostic method for certain parasitic infections, such as ...

    en.wikipedia.org/wiki/Reference_ranges_for_blood...

    Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...

  4. 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/Complete_blood_count

    A complete blood count (CBC), also known as a full blood count (FBC), is a set of medical laboratory tests that provide information about the cells in a person's blood.The CBC indicates the counts of white blood cells, red blood cells and platelets, the concentration of hemoglobin, and the hematocrit (the volume percentage of red blood cells).

  6. Leukemoid reaction - Wikipedia

    en.wikipedia.org/wiki/Leukemoid_reaction

    Conventionally, a leukocytosis exceeding 50,000 WBC/mm 3 with a significant increase in early neutrophil precursors is referred to as a leukemoid reaction. [2] The peripheral blood smear may show myelocytes, metamyelocytes, promyelocytes, and rarely myeloblasts; however, there is a mixture of early mature neutrophil precursors, in contrast to the immature forms typically seen in acute leukemia.

  7. Elliptocyte - Wikipedia

    en.wikipedia.org/wiki/Elliptocyte

    Rare elliptocytes (less than 1%) on a peripheral blood smear are a normal finding. [citation needed] These abnormal red blood cells are seen in higher numbers in the blood films of patients with blood disorders such as: [4] Hereditary elliptocytosis and Southeast Asian ovalocytosis; Thalassemia; Iron deficiency; Myelodysplastic syndrome and ...

  9. 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 .
