Hemoglobin 87

The hemoglobin index is actually very important for everyone's body. If there is a problem with your hemoglobin, it means that there is some disease in your blood vessels. So when you find that your hemoglobin is 87 during the examination, don't be too nervous. After all, everyone's physical condition is completely different, especially children's physical condition is generally lower than that of adults.

The hemoglobin reference value varies slightly depending on gender and age. The reference range is as follows:

1. Male

120～165g/L (12.0～16.5g/dl)

2. Female

110～150g/L (11.0～15.0g/dl)

3. Babies

160～220g/L (16.0～22.0g/dl)

4. Children

110～160g/L (11.0～16.0g/dl)

The hemoglobin level in children decreases with age and approaches that of adults.

The physiological and pathological variations of hemoglobin are roughly the same as those of red blood cells. However, in various anemias, the reduction of red blood cells and hemoglobin is not necessarily in a parallel relationship.

1. Physiological increase

Newborns, plateau residents, etc.

2. Pathological increase

Polycythemia vera, dehydration caused by various reasons, congenital heart disease, cor pulmonale, etc.

3. Reduce

Various anemias (such as aplastic anemia, iron deficiency anemia, sideroblastic anemia, megaloblastic anemia, hemolytic anemia, thalassemia, etc.), massive blood loss (such as traumatic bleeding, surgical bleeding, postpartum bleeding, acute gastrointestinal bleeding, chronic blood loss caused by ulcers, etc.), leukemia, postpartum, chemotherapy, hookworm disease, etc.

The English abbreviation for hemoglobin is HGB or Hb. Hemoglobin is a special protein that transports oxygen within red blood cells and is the protein that makes blood red. It is composed of globin and heme. The globin part is a tetramer composed of two pairs of different globin chains (α chain and β chain). The International System of Units is now widely adopted, with the number of grams of hemoglobin in each liter (one thousand milliliters) of blood as the standard. The utility value of hemoglobin and red blood cells is similar. The increase and decrease of hemoglobin can refer to the clinical significance of the increase and decrease of red blood cells.

The most important component in red blood cells is hemoglobin, which is composed of globin and heme. The biosynthesis of globin is the same as that of general proteins. Heme is an iron porphyrin compound and a cofactor of hemoglobin as well as myoglobin, cytochrome, peroxidase, catalase, etc. Heme involved in hemoglobin synthesis is mainly synthesized in immature red blood cells and reticulocytes in the bone marrow.
