Mean Platelet Volume (MPV)

The average platelet volume represents the average volume of a single platelet, which is more valuable when combined with PLT changes. The average volume of platelets is increased. It is seen in patients with excessive platelet destruction and good bone marrow compensatory function. It is the index that first reflects the recovery of hematopoietic function after suppression of hematopoietic function. Basic Information Specialist classification: cardiovascular examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Tips: When bone marrow hematopoietic failure, the average platelet volume and platelet count continue to decline. The more severe the inhibition of hematopoietic function, the smaller the average platelet count. When the hematopoietic function is restored, the average platelet volume is first increased, and then the platelet count is increased. Normal value Blood cell automatic analyzer 6.8 ~ 13.5fl (6.8 ~ 13.5 μm3). Clinical significance The average volume of platelets is increased. It is seen in patients with excessive platelet destruction and good bone marrow compensatory function. It is the index that first reflects the recovery of hematopoietic function after suppression of hematopoietic function. The average volume of platelets is reduced, which is seen in bone marrow hematopoietic dysfunction and reduced platelet production. Low results may be diseases: thrombosis, secondary thrombocytosis, high results may be diseases: radiation sickness, thrombocytopenic purpura precautions Judging bone marrow hematopoietic function: When bone marrow hematopoietic failure occurs, platelet mean volume and platelet count continue to decrease at the same time. The more severe the inhibition of hematopoietic function, the smaller the average platelet count. When the hematopoietic function is restored, the average platelet volume is first increased, and then the platelet count is increased. Inspection process Subjects were venously collected and assayed in time for serum separation. Impedance method by automatic blood cell analyzer. Not suitable for the crowd 1. Patients who have taken contraceptives, thyroid hormones, steroid hormones, etc., may affect the results of the examination and prohibit patients who have recently taken the drug history. 2, special diseases: patients with hematopoietic function to reduce disease, such as leukemia, various anemia, myelodysplastic syndrome, etc., unless the examination is essential, try to draw less blood. Adverse reactions and risks 1, subcutaneous hemorrhage: due to pressing time less than 5 minutes or blood draw technology is not enough, etc. can cause subcutaneous bleeding. 2, discomfort: the puncture site may appear pain, swelling, tenderness, subcutaneous ecchymosis visible to the naked eye. 3, dizzy or fainting: in the blood draw, due to emotional overstress, fear, reflex caused by vagus nerve excitement, blood pressure decreased, etc. caused by insufficient blood supply to the brain caused by fainting or dizziness. 4. Risk of infection: If you use an unclean needle, you may be at risk of infection.
