What is the normal value of hemoglobin in newborns?

Many people know that the hemoglobin value will affect our physical health, but what they don’t know is that the hemoglobin value of a newborn is different from that of an adult. In many cases, what we need to do is to observe carefully. If your child is feeling uncomfortable, you should go to the hospital for examination in time.

Under normal circumstances, the red blood cell count of a newborn is 6-7×1012/L, and the hemoglobin count is 170-230g/L. This decreases by about 20% around 10 days after birth. Later, due to rapid growth and development, rapid increase in blood volume, and temporary low bone marrow hematopoietic function, the red blood cell count drops to about 4×1012/L and the hemoglobin count is about 110 g/L at 3-4 months. It then rises slowly and reaches adult levels at around 12 years old, i.e., red blood cell count 4.5-5.5×1012/L, and hemoglobin 120-160 g/L. The normal hemoglobin value varies with age. Anemia is considered when it is less than 145 g/L in the neonatal period, less than 90 g/L at 4 months, less than 100 g/L at 4 to 6 months, less than 110 g/L at 6 months to 6 years, and less than 120 g/L at 6 to 12 years. The parts of the body that are most likely to show anemia are the conjunctiva, lips, and nails. When anemia occurs, the child often appears pale. Parents should pay close attention to observation. The identification of anemia must be combined with a routine blood test. For more complicated anemia, a bone marrow puncture may be required if necessary. Hemoglobin is blood pigment, and the normal level for women is 110-150g/L. Generally, too few red blood cells or low hemoglobin is called anemia. Judging from your values, you are anemic. However, for most women, due to their menstrual cycles, a few slight differences in values ​​do not indicate a big problem.

Hemoglobin is the main component of red blood cells. Each hemoglobin molecule is composed of four heme groups and globin, and each heme is composed of four pyrrole rings with an iron atom in the center of the ring. When the iron in hemoglobin is in a divalent state, it can reversibly bind to oxygen (oxyhemoglobin). If the iron is oxidized to a trivalent state, Hemoglobin is converted into methemoglobin and loses its oxygen-carrying capacity.

Men: 120-160 g/L;

Women: 110-150 g/L;

Newborn: 170-200 g/L;

Children: 110-160g/L.

The above is about the normal value of hemoglobin in newborns. I hope it will be helpful to everyone. In many cases, what we need to do is to observe, observe the child’s health status, and pay attention to the child’s health. This is very good. In our daily life, we should pay good attention to the child’s health and know some medical knowledge. This is very good.
