A platelet count of 0.37% exceeds the normal range of 0.11%-0.23% and is considered elevated. If only one item of platelet pressure is abnormal and the rest of the indicators are normal, there is no need to worry too much. If there are other uncomfortable symptoms or abnormal test results, you should consult a doctor in time to identify the primary disease. The main causes of elevated platelet pressure include physiological factors and pathologic factors, which need to be clarified. 1. Physiological factors of elevated platelet pressure: Platelet pressure is the product of the average volume and number of platelets. Generally speaking, strenuous exercise and pregnancy will lead to an increase in the number of platelets, which will lead to an elevated platelet pressure, which is a normal physiological condition, and it can be restored to normal after observing for a period of time. 2. Pathological factors of elevated platelet pressure: including acute blood loss, hemolytic disease, leukemia, etc., which will lead to high platelet count, as well as diseases that will lead to a large reduction in blood volume, such as excessive dehydration, vomiting, severe diarrhea, etc., further examination is needed to identify the primary disease and treat it symptomatically. Abnormal platelet pressure index should be analyzed together with other test results, and the cause of the disease should be identified and actively treated under the guidance of the doctor to avoid deterioration of the situation.
