What is the normal value of human platelets

If the human body's platelets are healthy, it means that the body is particularly healthy, so many people want to fully understand what is the normal value of human platelets? The following content gives a detailed introduction to many friends who want to fully understand these contents. If you want to know more, you can see the detailed answer below.

The concept of platelet count refers to the number of platelets in a unit volume of blood. The normal value of platelet count is 100-300×10^9/L. Thrombocytopenia causes prolonged bleeding time, and bleeding may occur in severe injury or in an excited state. When the platelet count is <50×10^9/L, mild injuries can cause purpura of the skin and mucous membranes, and bleeding may occur after surgery; when the platelet count is <20×10^9/L, spontaneous bleeding often occurs. It is generally believed that when the platelet count is <20×10^9/L, prophylactic platelet transfusion is required. If the platelet count is >50×10^9/L and the platelet function is normal, there will be no obvious bleeding during the operation.

1. Thrombocytosis: When the platelet count is >400×10^9/L, it is thrombocytosis. Primary thrombocytosis is common in myeloproliferative diseases, such as chronic myeloid leukemia, polycythemia vera, essential thrombocythemia, etc.; thrombocytosis is common in patients with acute and chronic inflammation, iron deficiency anemia and cancer. This type of increase generally does not exceed 500×10^9/L. The situation improves after treatment and the platelet count will quickly drop to normal levels. After splenectomy, platelet count will increase significantly, often higher than 600×10^9/L, and then slowly decrease to the normal range.

2. Thrombocytopenia: When the platelet count is <100×10^9/L, it is thrombocytopenia, which is common in platelet production disorders such as aplastic anemia, acute leukemia, acute radiation sickness, etc.; increased platelet destruction, such as idiopathic thrombocytopenic purpura, hypersplenism, excessive consumption such as disseminated intravascular coagulation, familial thrombocytopenia such as giant platelet syndrome, etc.

What is the normal value of human platelets? The above content has given a comprehensive introduction. Therefore, for friends who want to have a comprehensive understanding, I believe that through the above introduction, they have a comprehensive understanding and knowledge of the normal value of human platelets. After understanding it, you must pay attention to maintaining health in daily life. In terms of life, you must pay attention to details to make your body healthier.
