Introduction

In general, blood test reports are evaluated based on indicators such as red blood cell count, white blood cell count, platelets, hemoglobin, and neutrophil percentage. Red blood cell count refers to the number of red blood cells per liter of blood and can be used to monitor red blood cell production and apoptosis. The normal range for red blood cell count in adult males is 4.0–5.5×10^12/L.

Generally, a blood test report is interpreted by examining indicators such as red blood cell count, white blood cell count, platelet count, hemoglobin, and neutrophil percentage. The specific analysis is as follows:

1. Red Blood Cell (RBC) Count: This refers to the number of red blood cells per liter of blood and helps monitor red blood cell production and destruction. The normal RBC count for adult males ranges from 4.0 to 5.5 × 10¹²/L, and for adult females, it is 3.5 to 5.0 × 10¹²/L.

2. White Blood Cell (WBC) Count: This measures the number of white blood cells in the blood and helps detect conditions such as acute infections or leukemia. The normal WBC count for adults is 3.5–9.5 × 10⁹/L, for infants it is 15.0–20.0 × 10⁹/L, and for children, 5.0–12.0 × 10⁹/L.

3. Platelet Count: This indicates the number of platelets in the blood, with a typical normal range of 100–300 × 10⁹/L.

4. Hemoglobin: Hemoglobin is a protein in the blood responsible for oxygen transport and gas exchange. The normal hemoglobin range for adult males is 120–160 g/L, and for adult females, it is 110–150 g/L.

5. Neutrophil Percentage: This refers to the proportion of neutrophils among the total white blood cells. The normal neutrophil percentage ranges from 50% to 75%.

If any of these indicators are abnormal, it is recommended to seek medical attention promptly to avoid delaying diagnosis and treatment.

Can blood tests detect AIDS?

Whether blood tests can detect HIV depends mainly on the stage of infection. After the window period, when the viral load is high and sufficient antibodies are present, blood tests can usually determine whether a person has HIV. However, during the window period, when the viral load is low and antibody levels are insufficient, blood tests may fail to detect the infection. Therefore, it is recommended to undergo testing after the window period to allow timely treatment based on test results.
