Mean Platelet Volume (MPV)

The mean platelet volume (MPV) refers to the mean of platelet volume, while the platelet mean volume size is nonlinearly negatively correlated with platelet count. Therefore, when considering the significance of platelet mean volume, it should be combined with changes in platelet count to help determine bone marrow 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 (1) Increase May-Hegglin abnormalities, immune thrombocytopenia, giant thrombocytosis, and thrombosis. (2) Reduce Wiscott-Adrich syndrome, recovery from thrombocytopenia, acute radiation sickness, and intense chemotherapy. Low results may be diseases: thrombosis, high incidence of thrombotic diseases in the elderly may be diseases: radiation sickness, secondary thrombocytosis, thrombocytopenic purpura 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.
