Macroplatelet ratio is the proportion of large platelets to total platelets. The normal range for the large platelet ratio is 17.5% to 42.3%. When the large platelet ratio exceeds the normal range, it indicates that platelet maturation is reduced, and acute infection and excessive blood loss may occur. 1. Acute infection: it refers to the pathological phenomenon that pathogens multiply after invading into the human body, and the infection may lead to respiratory tract infection, such as fever and cough and coughing up sputum, etc., and anti-infective drugs, such as amoxicillin, etc., should be used. May induce urinary tract infection, such as frequent and urgent urination and painful urination symptoms, need to take antibiotic drugs, such as levofloxacin and so on. 2. Excessive blood loss: the physiological function of platelets is mainly for hemostasis, such as gastrointestinal bleeding, you need to go to the hospital in a timely manner, when a large amount of blood loss, the need to enter the red blood cells. The ratio of large platelets can reflect the state of bone marrow hematopoiesis. If the platelet ratio is high, you need to go to the hospital in time for treatment under the guidance of the doctor.
