Introduction

Under normal circumstances, a child's complete blood count (CBC) test results include white blood cells, red blood cells, hemoglobin, platelets, neutrophils, etc. These numerical values on the test report can generally assist in ruling out or diagnosing related diseases. For detailed interpretation, it is recommended to consult a doctor. In summary, a child's CBC test provides important information about their blood health.

Under normal circumstances, a child's complete blood count (CBC) test report includes white blood cells, red blood cells, hemoglobin, platelets, neutrophils, and other indicators. These numerical results can assist in ruling out or diagnosing related diseases. For specific details, it is recommended to consult a physician. The detailed analysis is as follows:

1. White Blood Cells

White blood cells are part of the immune system and help fight infections. The normal range is (5–12) × 10⁹/L. Values above or below this range may indicate infection or other health issues.

2. Red Blood Cells

Red blood cells carry oxygen to various parts of the body. The normal range is (6–7) × 10¹²/L. Levels below the normal range may suggest anemia, while higher levels could be associated with dehydration or other conditions.

3. Hemoglobin

Hemoglobin is a protein in red blood cells responsible for oxygen transport. The normal value for children is 110–150 g/L. Significantly low values may be related to iron deficiency anemia or megaloblastic anemia; conversely, elevated levels may indicate hypoxia or polycythemia vera.

4. Platelets

Platelets play a key role in stopping bleeding. The normal range is (100–300) × 10⁹/L. A significantly low count may indicate bleeding disorders, whereas a high count often suggests a hypercoagulable state.

5. Neutrophils

The proportion and count of neutrophils can provide clues about infection or inflammation. The normal value for children is (15–20) × 10⁹/L. Abnormal results may be associated with acute tissue injury, acute bacterial infection, or acute poisoning.

In summary, a child's CBC test provides important information about their blood health. However, interpretation of these results should be performed by a qualified physician to ensure accuracy and appropriate medical management.
