Large platelet ratio (P-LCR)

The proportion of large platelets (P-LCR) refers to the percentage of large platelets in the blood. Platelets are disc-shaped, ranging from 1 to 4 microns to 7 to 8 microns in diameter, and vary widely from individual to individual (5 to 12 cubic microns). Because of its ability to move and deform, platelets are multi-form when observed by general methods. In general, the ratio of large platelets is high, and the probability of hemorrhage and thrombosis is increased. If the above indicators are normal, the coagulation function is normal, there should be no major problems, and no medication is needed. Usually pay attention to diet, eat less high-sugar, high-fat greasy food, try to light diet, use more fresh vegetables and fruits, black fungus and so on. Basic Information Specialist classification: cardiovascular examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Tips: Before the examination, listen to the doctor's arrangements. Normal value Reference value: 100-300*109/L. Clinical significance The reason for the high single large platelets alone has no important clinical significance and needs to be combined with other test results. Acute blood loss, hemolytic anemia, polycythemia vera, and chronic myeloid leukemia after splenectomy can cause large platelet elevation. The lower cause may be caused by hypersplenism, regenerative anemia, radiation sickness, disseminated intravascular coagulation, acute leukemia, immune or idiopathic thrombocytopenic purpura, and certain drugs. Need to cooperate with other inspections to judge. Low results may be diseases: hemolytic anemia, aplastic anemia high results may be diseases: secondary polycythemia, radiation sickness, acute blood loss anemia considerations Before the examination, listen to the doctor's arrangements. Inspection process Subjects were venously collected and assayed in time for serum separation. Take appropriate platelets and then perform an assay. 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.
