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 reference range is usually defined as the set of values 95 percent of the normal population falls within ... Mean platelet volume (MPV) 7.2, [147] 7.4, [148] 7.5 [149]
Platelet concentrations vary between individuals and over time, with the population average between 250,000 and 260,000 cells per mm 3 (equivalent to per microliter), but the typical laboratory accepted normal range is between 150,000 and 400,000 cells per mm 3 or 150–400 × 10 9 per liter.
The platelet count can be reported in units of cells per microlitre of blood (/μL), [165] 10 3 cells per microlitre (× 10 3 /μL), or 10 9 cells per litre (× 10 9 /L). [4] The mean platelet volume (MPV) measures the average size of platelets in femtolitres.
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 normal range (99% of population analyzed) for platelets is 150,000 to 450,000 per cubic millimeter. [6] If the number of platelets is too low, excessive bleeding can occur.
In hematology, thrombocythemia is a condition of high platelet (thrombocyte) count in the blood. 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.
In a typical set of rules, a platelet donor must weigh at least 50 kg (110 lb) and have a platelet count of at least 150 x 10 9 /L (150,000 platelets per mm³). [2] One unit has greater than 3×10 11 platelets. Therefore, it takes 2 liters of blood having a platelet count of 150,000/mm³ to produce one unit of platelets.
