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 ...
A pseudothrombocytopenia false-positive result may occur when automated platelet counting devices are used. As a means of double checking the results, the patient's blood sample is often examined under a microscope. If the clumping is visible and the number of platelets appears normal, pseudothrombocytopenia may be concluded.
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).
A counting chamber, is a microscope slide that is especially designed to enable cell counting. Hemocytometers and Sedgewick Rafter counting chambers are two types of counting chambers. The hemocytometer has two gridded chambers in its middle, which are covered with a special glass slide when counting.
Hematology analyzers are used to conduct a complete blood count (CBC), which is usually the first test requested by physicians to determine a patient's general health status. [5] A complete blood count includes red blood cell (RBC), white blood cell (WBC), hemoglobin , and platelet counts, as well as hematocrit levels.
Blood smear examination is usually performed in conjunction with a complete blood count in order to investigate abnormal results or confirm results that the automated analyzer has flagged as unreliable. [3] Microscopic examination of the shape, size, and coloration of red blood cells is useful for determining the cause of anemia.
Microangiopathic hemolytic anemia may be suspected based on routine medical laboratory tests such as a CBC (complete blood cell count). Automated analysers (the machines that perform routine full blood counts in most hospitals) are designed to flag blood specimens that contain abnormal amounts of red blood cell fragments or schistocytes.

A complete blood count (CBC) may show increased reticulocytes, a sign of increased red blood cell production, and decreased hemoglobin and hematocrit. The term "non-hereditary spherocytosis" is occasionally used, albeit rarely. [2] Lists of causes: [3] Warm autoimmune hemolytic anemia; Cold autoimmune hemolytic anemia/paroxysmal cold hemoglobinuria
