"Is blood test necessary for anemia diagnosis?"

Whether anemia requires blood tests for diagnosis is generally related to the severity of the anemia. If the patient has only mild anemia, blood tests are not necessary; however, if the patient has severe anemia, blood tests are typically required.

1. Not Required:

Anemia refers to a clinical condition where the number of red blood cells in the peripheral blood decreases, resulting in inadequate oxygen supply to tissues and organs when falling below the normal range. Iron deficiency anemia caused by a lack of hematopoietic raw materials due to insufficient intake or absorption of iron, vitamin B12, and folic acid is the most common type. In cases of mild anemia without significant discomfort, blood tests are generally not necessary. Instead, dietary adjustments can be made, such as consuming iron-rich foods like pig liver and spinach.

2. Required:

However, if the patient's condition is severe and symptoms like pallor and fatigue appear, prompt blood tests at a hospital are necessary to assess the blood routine and guide targeted treatment based on the underlying cause under medical supervision. In daily life, patients are advised to rest adequately, avoid excessive fatigue, maintain a balanced diet rich in high-quality protein, fresh fruits, and vegetables, and limit spicy, greasy, and stimulating foods.
