During blood test and examination for anemia patients, it is usually possible to detect whether they suffer from anemia. If anemia is suspected, it is recommended to promptly visit the hospital and undergo relevant examinations under the guidance of a doctor.

Observable Manifestations

1. Red Blood Cells: The normal number of red blood cells in the blood of adult males is 4-5.5 million per cubic millimeter, while for females, it is 3.5-5 million per cubic millimeter. When the value is lower than this range, it indicates the possible presence of anemia.

2. Hemoglobin: The hemoglobin concentration of adult males ranges from 120-160g/L, while for females, it ranges from 110-150g/L. If the value falls below this range, it may also indicate anemia.

3. Mean Corpuscular Volume (MCV): MCV is a parameter reflecting the contents of red blood cells and can be used to determine macrocytic or microcytic anemia. The normal reference value is 82-97fL. If the value is lower than this, it may indicate diseases such as iron-deficiency anemia or thalassemia.

4. Mean Corpuscular Hemoglobin Concentration (MCHC): MCHC refers to the amount of hemoglobin per liter of blood. The normal reference value for adults is 32%-36%. If the value is higher than this, it is commonly seen in thalassemia. If the value is lower than this, it is commonly seen in iron-deficiency anemia.

Non-Observable Manifestations

Apart from the above indicators, a comprehensive diagnosis needs to be made by combining reticulocyte count, bone marrow aspiration, and other relevant test results. For example, the percentage of reticulocytes normally accounts for 0.5%~1% of the total white blood cells. If the percentage decreases, it often indicates a decrease in hematopoietic function, and further bone marrow aspiration examination is needed to identify the cause.

For anemia caused by acute blood loss, it is generally not possible to detect the presence of anemia through blood routine tests. Anemia patients need to undergo targeted treatment based on their own conditions to improve discomfort symptoms. In daily life, pay attention to a balanced diet and eat more iron-rich foods, such as animal liver, red dates, and spinach, which are beneficial for replenishing the body's nutrients and promoting recovery.
