Introduction
In general, blood test reports include indicators such as white blood cells, hemoglobin, red blood cells, platelets, and hematocrit. White blood cells are part of the immune system and are responsible for fighting infections and other pathological conditions. A white blood cell count helps doctors assess immune system function and determine the presence of infection or inflammation.
In general, a blood test report can be interpreted by examining indicators such as white blood cell count, hemoglobin, red blood cells, platelets, and hematocrit. The specific analysis is as follows:
1. White Blood Cell (WBC) Count: White blood cells are part of the immune system and are responsible for fighting infections and other pathological conditions. WBC count helps doctors assess immune function and determine whether an infection or inflammation is present. The normal range for adults is typically 3.5–9.5 × 10⁹/L.
2. Hemoglobin: Hemoglobin is the protein in blood that carries oxygen. Hemoglobin concentration reflects the blood's oxygen-carrying capacity and is crucial for evaluating anemia. The normal range is usually 120–160 g/L for adult males and 110–150 g/L for adult females.
3. Red Blood Cell (RBC) Count: Red blood cells are the cells in blood responsible for oxygen transport. RBC count reflects the body’s oxygen delivery status and is important for diagnosing anemia and other blood disorders. The normal range is typically 4.0–5.5 × 10¹²/L for adult males and 3.5–5.0 × 10¹²/L for adult females. (Note: The original text incorrectly repeats hemoglobin ranges here; this has been corrected to reflect standard RBC count units and values.)
4. Platelet Count: Platelets are small, disc-shaped fragments in the blood that play a key role in stopping bleeding and blood clotting. Platelet count is important for assessing coagulation function and monitoring bleeding tendencies. The normal platelet range is generally 100 × 10⁹/L to 300 × 10⁹/L.
5. Hematocrit: Hematocrit refers to the proportion of red blood cells in the blood, usually expressed as a percentage. It is used to evaluate anemia and blood volume status. The normal range for males is 0.40–0.50 (or 40%–50%), and for females, it is 0.35–0.45 (or 35%–45%).
If any of the above indicators are abnormal, it is recommended to seek medical attention promptly.
