Introduction

In general, blood test reports are interpreted by examining indicators such as red blood cells, white blood cells, fasting blood glucose, hemoglobin concentration, and total cholesterol. Red blood cells are responsible for carrying oxygen to various parts of the body. They provide information about anemia, polycythemia, and other blood disorders. The normal range for adult males is 4.0–5.5 × 10^12/L.

Under normal circumstances, a blood test report is interpreted by examining indicators such as red blood cells, white blood cells, fasting blood glucose, hemoglobin concentration, and total cholesterol. The specific analysis is as follows:

1. Red Blood Cells (RBC): Red blood cells are responsible for carrying oxygen to various parts of the body. RBC levels provide information about anemia, polycythemia, and other blood disorders. The normal range for adult males is 4.0–5.5 × 10¹²/L, and for adult females, it is 3.5–5.0 × 10¹²/L.

2. White Blood Cells (WBC): White blood cells are part of the immune system and help fight infections and diseases. A white blood cell count can help identify the presence of infection, inflammation, or immune system disorders. The normal WBC range for adults is 3.5–9.5 × 10⁹/L.

3. Fasting Blood Glucose: Fasting blood glucose refers to the blood sugar level after at least 8 hours without caloric intake. Measuring fasting glucose is used to screen for diabetes or monitor blood sugar control in individuals with diagnosed diabetes. The normal fasting blood glucose range is 4.4–6.1 mmol/L.

4. Hemoglobin: Hemoglobin is the protein in red blood cells that carries oxygen throughout the body. Hemoglobin concentration provides key information about anemia. The normal hemoglobin range is 120–160 g/L for adult males and 110–150 g/L for adult females.

5. Total Cholesterol: Total cholesterol is one of the indicators related to cardiovascular health. Elevated total cholesterol levels may increase the risk of atherosclerosis and heart disease. The ideal total cholesterol level is less than 5.18 mmol/L.

If any of the above indicators are abnormal, it is recommended to seek medical attention promptly.
