Is hemoglobin the critical value for detecting anemia

Hemoglobin testing is a core indicator for screening anemia, with a threshold value typically of 120g/L for adult males and 110g/L for females. To determine anemia, a comprehensive analysis of indicators such as red blood cell count and hematocrit is required. The main influencing factors include nutritional deficiency, chronic blood loss, and bone marrow hematopoietic dysfunction.

1. Core indicator:

Hemoglobin is a protein responsible for carrying oxygen in red blood cells, and its concentration directly reflects the oxygen carrying capacity of the blood. Clinically, the World Health Organization standard is adopted: an adult male below 120g/L and a female below 110g/L can preliminarily determine anemia, and the critical value for pregnant women is 100g/L. When testing, it is important to note that altitude can affect the reference value. For every 1000 meters increase, the normal hemoglobin value increases by about 4%.
