Mean platelet volume (MPV) is a machine-calculated measurement of the average size of platelets found in blood and is typically included in blood tests as part of the CBC. Since the average platelet size is larger when the body is producing increased numbers of platelets, the MPV test results can be used to make inferences about platelet ...
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).
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 ...
A normal human platelet count ranges from 150,000 to 450,000 platelets/microliter (μL) of blood. [4] Values outside this range do not necessarily indicate disease. One common definition of thrombocytopenia requiring emergency treatment is a platelet count below 50,000/μL. [5]
The prevalence of pseudothrombocytopenia in K2-EDTA reported in different studies ranges from 0.03 to 0.27 percent in outpatients, [3] which accounts for 15 to 30 percent of all cases of isolated thrombocytopenia. Tests can mistake small clumps of platelets for leukocytes, thus showing a pseudoleukocytosis in blood counts. [4] Platelet ...
Normal count is in the range of 150 × 10 9 to 450 × 10 9 platelets per liter of blood, [1] but investigation is typically only considered if the upper limit exceeds 750 × 10 9 /L. When the cause is unknown, the term thrombocythemia is used, as either primary thrombocythemia or essential thrombocythemia .
Pancytopenia is a medical condition in which there is significant reduction in the number of almost all blood cells (red blood cells, white blood cells, platelets, monocytes, lymphocytes, etc.). If only two parameters from the complete blood count are low, the term bicytopenia can be used. The diagnostic approach is the same as for pancytopenia.
The normal mean corpuscular volume (abbreviated to MCV on full blood count results, and also known as mean cell volume) is approximately 80–100 fL. When the MCV is <80 fL, the red cells are described as microcytic and when >100 fL, macrocytic (the latter occurs in macrocytic anemia). The MCV is the average red blood cell size.
