What is the range of average hemoglobin concentration

The normal range of average hemoglobin concentration is 320-360 grams per liter, which reflects the concentration of hemoglobin in red blood cells and is commonly used for differential diagnosis of anemia types. The average hemoglobin concentration is one of the important parameters in blood routine examination, which is measured by a fully automated blood analyzer. Clinically, 320-360 grams per liter is usually used as the standard reference range. A value below 320 grams per liter may indicate small cell hypochromic anemia such as iron deficiency anemia, chronic disease anemia, or thalassemia, where the red blood cell volume is small and the hemoglobin content is insufficient. Cases above 360 grams per liter are relatively rare and may be related to physiological conditions such as dehydration, burns, severe vomiting that lead to blood concentration, as well as hemolytic diseases such as hereditary spherocytosis. During testing, it is necessary to eliminate interference factors such as sample hemolysis and lipid blood. Venous blood testing results are more stable and reliable than peripheral blood. Due to differences in testing equipment and methods, the reference range may vary slightly among different laboratories, but generally does not exceed the medical consensus range of 310-380 grams per liter. When abnormal average hemoglobin concentration is detected, it is recommended to make a comprehensive judgment based on indicators such as red blood cell count, average red blood cell volume, and red blood cell distribution width. Daily attention should be paid to balanced intake of iron rich foods such as animal liver, lean meat, spinach, etc., and avoiding long-term consumption of strong tea that affects iron absorption. Pregnant women, teenagers, and patients with gastrointestinal bleeding can regularly monitor this indicator, and after vigorous exercise, they need to supplement enough water to prevent false elevation caused by blood concentration.
