Can a blood routine test detect the type of anemia

Blood routine examination can generally preliminarily determine anemia, but cannot directly determine the specific type of anemia. Blood routine examination can screen for anemia through indicators such as hemoglobin concentration, red blood cell count, and hematocrit. When the hemoglobin concentration is lower than the normal value, it indicates the possibility of anemia, and combined with the average red blood cell volume, it can preliminarily distinguish between small cell anemia, positive cell anemia, or large cell anemia. For example, iron deficiency anemia is often manifested as small cell hypochromic anemia, while megaloblastic anemia is often manifested as large cell anemia. But to determine the specific type and cause of anemia, further tests such as serum iron metabolism indicators, folate and vitamin B12 levels, hemoglobin electrophoresis, and bone marrow puncture are usually required. The ability of blood routine examination to differentiate and diagnose special types of anemia such as hemolytic anemia and aplastic anemia is limited.

It is recommended to seek medical attention promptly when abnormal anemia indicators are detected. Doctors will determine the type of anemia based on blood routine results combined with other specialized examinations. In daily life, it is advisable to increase the intake of iron rich foods such as animal liver and lean meat in moderation, while ensuring the intake of fresh vegetables and fruits to supplement folate and vitamins. Avoiding long-term consumption of strong tea and coffee can affect iron absorption, and regular sleep can also help improve anemia symptoms.
