Anemia is mainly determined by the indicator of hemoglobin concentration, in addition, in order to analyze the cause of anemia should also pay attention to iron metabolism, folic acid, vitamin B12 and other indicators.
The diagnosis of anemia is mainly based on the indicator of hemoglobin concentration (Hb). In the sea level region of China, Hb <120g/L in adult men, Hb <110g/L in adult women (non-pregnant women), and Hb <100g/L in pregnant women are defined as anemia.
In addition, after diagnosing a patient with anemia, it is necessary to comprehensively determine the cause of the anemia based on the patient's symptoms, signs, and other laboratory test indicators in order to target treatment.
For example, erythrocyte parameters such as mean corpuscular volume of red blood cells (MCV), mean corpuscular hemoglobin volume (MCH), mean corpuscular hemoglobin concentration (MCHC) are low, iron metabolism indicators such as serum ferritin, transferrin saturation is low can suggest iron deficiency anemia; folic acid, vitamin B12 is low, macrocytic anemia, should be considered megaloblastic anemia.
Specific disease diagnosis and treatment should be carried out under the guidance of physicians.
