    Exceptions are mainly those values that denote total blood concentration, and in this article they are: [3] All values in Hematology – red blood cells (except hemoglobin in plasma) All values in Hematology – white blood cells; Platelet count (Plt) A few values are for inside red blood cells only: Vitamin B 9 (folic acid/folate) in red blood ...

  3. 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 ...

    In the US, this is usually expressed as 4,000 to 11,000 white blood cells per microliter of blood. [7] White blood cells make up approximately 1% of the total blood volume in a healthy adult, [ 8 ] making them substantially less numerous than the red blood cells at 40% to 45% .

    Neutrophils are the most abundant white blood cells in the human body (approximately 10 11 are produced daily); they account for approximately 50–70% of all white blood cells (leukocytes). The stated normal range for human blood counts varies between laboratories, but a neutrophil count of 2.5–7.5 × 10 9 /L is a

    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).

    Major types of blood cells include red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes). Together, these three kinds of blood cells add up to a total 45% of the blood tissue by volume, with the remaining 55% of the volume composed of plasma , the liquid component of blood.
