There are a lot of red blood cells in the blood of the average person: for example, if the body weight is 60 kilograms, the total number of red blood cells in the human blood will be approximately 25 trillion. The production of red blood cells by the bone marrow is continuous, because "live" red blood cells only about 120 days. When the lifespan of red blood cells expires, they wear out and grow old - the spleen and liver are already being "disposed" of already unnecessary blood cells, and the bone marrow in the meantime supplies young erythrocytes to the bloodstream. During pregnancy, constant monitoring of the indicators of the quantity and quality of red blood cells becomes mandatory. For this, a general (clinical) blood test is used, which, in addition to the number of red blood cells, also determines the rate of erythrocyte sedimentation.
A general blood test is performed by taking a prototype of blood from the finger. If the analysis shows a small decrease in the number of red blood cells, physicians classify it as the norm: during pregnancy, the need for hemoglobin greatly increases. But a significant reduction in the number of erythrocytes and hemoglobin during gestation causes the physician to be alarmed: this state of affairs indicates the development of anemia, which can cause certain complications of pregnancy. If the fact of the presence of anemia is established, you must immediately begin to eliminate it, in order to prevent possible oxygen starvation of the fetus, delay its development, premature birth.
The analysis of the erythrocyte sedimentation rate (ESR, and sometimes the abbreviation ROE - the erythrocyte sedimentation reaction) also becomes the norm for pregnant women. The rate of erythrocyte sedimentation is the amount of time that is necessary for the deposition of red blood cells and the appearance of "above them" plasma. For example, if you pour fresh blood into a glass flask standing in an upright position, you can see in the near future how the erythrocytes drop out and the transparent layer of plasma is formed on top of the flask. The number of erythrocytes that precipitate within 1 hour is measured in millimeters - this is the indicator of ESR. In pregnancy, the rate of erythrocyte sedimentation is usually increased: if in non-pregnant women the ESR value is up to 15 millimeters per hour, then during the gestation of the child, the erythrocytes settle at a rate of 45 millimeters per hour. Also, often the first two trimester can be characterized by decreased ESR, but at the end of pregnancy it increases almost threefold.
Interest for doctors is during pregnancy and the quantitative composition of erythrocytes in the urine. An appropriate analysis for the expectant mother is mandatory, because with the development of the fetus and the growth of the uterus, the organs of the genitourinary system are shy, which can lead to exacerbation of chronic diseases. The presence of these can be evidenced by an increased amount of erythrocytes in the urine. The erythrocytes found in urine during pregnancy can report problems of the urinary and urogenital tract. Therefore, if an increased number of erythrocytes in urine was recorded, the procedure of ultrasound of the kidneys and bladder, the analysis for bacteriological culture of urine, will be expedient.
The future mother is obliged to treat her health and the condition of the whole organism with increased attention and responsibility. Regular analysis is one of the components of proper health control during pregnancy. And they should not be neglected, because in time detected any changes, including those relating to red blood cells, can prevent the development of a possible disease, often potentially dangerous for the baby.
