- Hemoglobin: normal children
- Norma hemoglobin in the adult
Hemoglobin - is a complex protein compound that is found in red blood cells and gives them a red color.Without it can not transport oxygen and carbon dioxide through the body, that is breathing.It is a substance binds oxygen in the lungs, a current spreads through the arterial tissues gives them picks up oxygen and carbon dioxide, which already carries a venous blood flow into the lungs.
for important functions of respiration hemoglobin in the blood to be contained in a certain amount.If it is not enough, the person shows signs of oxygen starvation.This state and accordingly a disease in which the hemoglobin is less than norm, called anemia.
However, too high a concentration of red respiratory pigment - it is also a sign of pathological characteristic for some diseases of the heart and lungs, dehydration and other conditions.Therefore, the determination of hemoglobin concentration is considered to be one of the basic laboratory research that was carried out as sick people and healthy patients during regular checkups.
Norma hemoglobin in the blood - is the amount of pigment that allows to control the body.People of different genders and ages, this rule is different, which is associated with a number of physiological characteristics.Therefore doctors to carry out the most accurate interpretation of test results, always taking into account the sex and age of the patient.
usually determined hemoglobin concentration in grams per liter of blood (g / l).In some laboratories, the measurement results may be represented in other units, such as g / dl.To put these figures in g / l, it is necessary value in g / dl multiplied by 10.
Hemoglobin: normal children
The boys and girls the normal value of this parameter equally, but in different age groups, it is cast.Thus, in children under one year normal hemoglobin concentration - 100-140 g / l.However, this is only the average numbers, since the baby in the first week of life, this indicator is much higher (1-2 days - up to 220 on day 10 and up to 180 g / l).
At the age of 1-2 months, the concentration of the respiratory pigment gradually decreases due to the collapse of fetal (fetal) hemoglobin, insufficient active education "adult" hemoglobin and red blood cells, as well as the sharp increase in the weight of the child and, accordingly, the volume of circulating blood in his body.For example, some babies for the first 2 months of life, gaining 60-70% of its original weight, and their bone marrow is simply no time to produce red blood cells.Therefore distinguish even such a state as physiological anemia in infants.
After a year and 6 years old children hemoglobin concentration should be between 110-145 g / l after six years is the norm value of the index in the range of 115-150 g / l.
Norma hemoglobin in the adult
Men hemoglobin in the blood should be in the framework of 130-160 g / l.It is more than that of women, for which the norm - 120-140 g / l.Such features of the doctors explain the fact that men tend to have great physical activity, which needs energy, oxygen and respiratory pigment, respectively.In addition, the concentration of hemoglobin in the blood in the body affects the male hormone testosterone.Because of this, bodybuilders and other athletes taking steroids, suffer from increased hemoglobin.Women athletes, this figure can also be upgraded, as they sometimes endure the load is much higher than any average man.
In addition, the concentration of hemoglobin in the fairer sex affects the menstrual cycle.Therefore, in the reproductive age, when a woman has a regular menstrual period, hemoglobin decrease may be up to 110 g / l.At the same time, anything below is considered by doctors as a manifestation of anemia.
During pregnancy, the lower limit concentration of hemoglobin is considered as 110 g / l.Such a fall in the rate is due to a physiological increase in the volume of blood circulating in the vessels of the expectant mother.An increase of this amount is due to the liquid portion of blood but not corpuscles, erythrocytes and therefore the pigment contained therein, becomes smaller.In addition, iron is required for the synthesis of a respiratory pigment, uses, and the child, in his body and blood formation processes occur, and fetal hemoglobin is produced.
If a pregnant patient's hemoglobin index falls below the limit of 110 g / l, doctors recommend that women certainly carry out the correction of their diet (to focus on foods that contain iron, proteins, vitamins) and prescribe iron supplements inside.This can prevent a variety of negative consequences that may arise due to oxygen starvation of the mother and baby.
summarize, we note that although hemoglobin is considered an important indicator of the laboratory, only for its concentration to judge whether a patient has anemia, the doctor can not.This requires a certain clinical data and results of other analyzes (such quantity indicators such as the number of red blood cells, a color indicator, the average content of hemoglobin in the red blood cell, etc.).
