The norm of erythrocytes in men and women: a table, basic indicators and transcript

When taking blood from a finger or from a vein, laboratory technicians examine our blood in order to find deviations from the norms. For example, a lack of red blood cells can talk about anemia, and an excess of white blood cells or a low index of ESR indicates a possible inflammatory process. All these indicators should be monitored. Moreover, the norm of erythrocytes in men is controlled.

Let's stop on red blood cells. These elements have a scarlet hue, since they transfer a red iron protein - hemoglobin. And if a hemoglobin deficiency is detected, it is necessary to investigate the cause, since the body receives less oxygen, and this can be dangerous. It is also necessary to check sometimes whether there are deviations in such a measure as the norm of erythrocytes in urine in men.

Red blood cells work in the body

Erythrocytes - the most, you can say, necessary elements of blood in the list of hematological indicators. Thanks to their work, the body breathes a much needed gas - oxygen;cells can be fed and fully functional. Taurus-erythrocytes also excrete carbon dioxide from tissues, participate in protecting the body from infections. And what if not blood helps us maintain a constant body temperature.

erythrocyte norm in men

Without erythrocytes a man could not live. In the body of an adult male there is somewhere 5 liters of blood( 8% of the total body weight).With this volume of blood, what is the norm of red blood cells in men? Let us consider these questions in more detail.

What is the difference between erythrocytes and reticulocytes?

The blood is constantly being updated. And if suddenly in the process of updating blood cells there are violations, a person can seriously get sick. Erythrocytes are originating within the bone marrow. The process of creation and development of these cells by erythropoiesis is called. And the process of renewing all blood is hemopoiesis. The production of reticulocytes is stimulated by the hormone erythropoietin( renal hormone).

If the body suddenly loses blood reserves or lacks air, the bone marrow receives a command to immediately develop new red blood cells. These young cells are still completely "empty", and within 2 hours their task is to be filled with hemoglobin.

Only then these cells can be called erythrocytes. And very young cells are called reticulocytes. Their level is also checked in a general analysis. Disturbances in the process of reticulocyte formation lead to a violation of the normal level of erythrocytes.

This is how important for us red blood cells( the norm in men by age).A table describing the age norms will be given below.

A significant deficiency of red blood cells due to any problems indirectly indicates the onset of severe anemia or even blood cancer. Sometimes anemia begins because the spinal cord produces few new bodies. Anemia is mild, moderate and severe. Severe anemia is noted when HGB is 70 g / L.But for the definition of cancer, you need to take a lot of other, more accurate and complex tests.

General blood analysis

Formal basic elements of blood have their functions and their norms. For each element there are tables, which indicate the norms for different ages. The slightest discrepancy between the data obtained in the analysis and the norms, worries doctors. The therapist is obliged to appoint a comprehensive examination if the erythrocyte norm in the blood of men or women is not observed.

What are the values ​​for adults?

The norm of erythrocytes in the blood of men and women is slightly different. All the differences are in the table below.

Indicator In men In women
Red blood cells RBC( 1012 / L) 4-5,6 3,6-4,6
Reticulocytes RTC 0,2-1,1 0,2-1,1
Hemoglobin HGB( g / l) 130-150 120-140
Leukocytes WBC( 109 / L) 4-9 4-9
Platelets PLT( 109 / L) 180-320 180-320

These are the basicindicators. They are enough to determine whether a person is healthy or not.

Reasons for changing the RBC level

Increasing the level of RBC is called erythrocytosis. And to describe the decline of this level there is the term "erythropenia", which is also known as "anemia".Erythropenia occurs in people who eat poorly, eat few vitamins. Or they lost a lot of blood because of internal bleeding.

Rise of erythrocytes has under itself such bases:

  • of illness or disease SSS;
  • pneumonia, bronchitis;
  • of blood disease;
  • polycystic kidney disease( or other kidney disease).

In addition to these diseases, the cause may be ordinary dehydration. Or the use of drugs of the steroid group. If a person takes such drugs, the doctor should be warned about it in advance. Otherwise, the rate will be exceeded for false reasons.

Erythrocytes: the norm in men by age. Table of normal indicators for men and women

All norms in the general analysis have a time frame. The given data are calculated for men and women of mature age. Normally, the number of erythrocytes in men is more than 5. But these norms change to old age. Let's see how the figures, which are considered to be the norm, change, depending on the age.

Age of the RBC male.(1012 / l) RBC female(1012 / L)
Up to 18 4-5,1 3,9-5,1
Up to 65 4,2-5,6 3,8-5,1
65 and more 3,8-5.6 3.8-5.1

Obviously, 40% of the total mass of blood is made up of red blood cells. The norm in men, women only in tenths is different. As can be seen from the table, the level of RBC in the blood of a man is higher than that of a woman. In addition, in women, this level is almost unchanged throughout life. But ESR in men is lower. This is due to physiology.

Erythrocytes in the urine. What is the reason?

To establish the disease, erythrocytes in urine are also investigated. The norm of erythrocytes in urine in men is estimated using Nechiporenko's analysis. In the clinic, under the microscope, the number of red bodies in a milliliter of urea is studied. Erythrocytes( RBC) can not be more than 1 thousand per milliliter.

In principle, red blood cells "travel" throughout the body. And through the vessels they penetrate into the urinary tract. However, hematuria( an increase in erythrocytes) is a bad indicator. And there is also a macrohematuria - this increase in red blood cells in the blood so that the urine changes its color to pink or red.

What does this mean? Sometimes these physiological changes are associated with a general overheating in the sun or in the sauna. Perhaps, the man was overworked physically, or there were a lot of spices in the food;and maybe there was alcohol in the body.

But it could also mean that everything is not well in the body. And the reason for somatic changes. You can expect in this case the following diseases:

  • kidney disease( very often ordinary kidney stones give such a color of urine) and the genitourinary system;
  • severe intoxication;
  • thrombocytopenia( reduced the number of platelets in the blood);
  • also speaks of hemophilia, which is a genetic abnormality.

In fact, the medical causes of hematuria are more than 100. In each case, you need to collect a detailed history and look for causes in the history of the patient's illnesses and watch for his well-being. The norm of RBC in urine sediment in men is from 0 to 14, and it is normal for women to have an index of up to two units, that is, of cells.


So, the UAC in addition to the main indicator( the norm of red blood cells in men or women) certainly explores and such items:

  • blood composition, the quality of the main bodies.
  • hematocrit;
  • hemoglobin;
  • ESR;
  • level of lymphocytes.

What is hematocrit? This indicator determines the ratio of the number of erythrocytes to plasma cells. The norm of erythrocytes in men in relation to plasma is 39-49%.And after 65 years - 37-51%.In women, the picture is slightly different: to 65 - from 35 to 47%;after this age - 35-47.

the normal number of erythrocytes in men

For more detailed biochemical analysis, blood is taken from the venous stream. In this case, such indicators as cholesterol, glucose, blood proteins, urea, bilirubin level and others are analyzed.


This indicator gives doctors information on the rate of erythrocyte sedimentation. Blood cells are negatively charged and, when moving in plasma, repel each other. Nevertheless, under certain conditions, they change their charge and begin to stick together.

red blood cells in men

The ESR or ESR( sedimentation rate in a test tube of blood cells) in women is higher than in men. That is, in men, ESR to 10 - the norm, and in women - to 15. However, during pregnancy or during menstruation, the indicator may increase to 20. Although each woman may have their own, different from other standards. Higher rates, clearly not fitting in the norm, are direct evidence of the inflammatory processes occurring in the body.
