What Does a Blood Routine Examination Test For?
Blood routine examination mainly checks red blood cells, white blood cells, and platelets, which is the most basic test. It can also detect whether there is anemia. Based on the number of white blood cells detected, it can initially determine whether leukemia is present and whether there is a fever. If some blood diseases occur, it will lead to a low platelet count.
1. White Blood Cell Examination: Most human suppurative bacterial infections are caused by the use of certain drugs, diseases such as influenza, radiation exposure, rheumatic diseases, and certain blood diseases. Infections such as measles, viral hepatitis, tuberculosis, and lymphocytic proliferative diseases can lead to an increase in lymphocytes. More common causes are exposure to radiation and the use of adrenal cortical hormones such as prednisone.
2. Red Blood Cell Count Examination: The number of red blood cells is affected by anemia or blood loss. When it is high, there may be an increase in red blood cells, and when it is low, it may indicate anemia.
3. Hemoglobin Examination: Hemoglobin is found in red blood cells and transports oxygen to provide the body with the oxygen it needs. Women are generally more prone to anemia due to menstruation and pregnancy, resulting in lower hemoglobin levels compared to men. High hemoglobin levels may indicate polycythemia or reduced cardiac output, while low levels may indicate hypochromic anemia or iron deficiency anemia.
