General blood analysis. How to decrypt.

  • Hemoglobin, abbreviated as HB, HgB is a protein rich in iron that binds to oxygen in the body;
  • Oxygen - O2 - is involved in 90% of the processes of obtaining energy for the body, it is transferred from the lungs to cells with the blood;
  • Red blood cells (RBC - Red Blood Cells, English) - red blood cells, the main transporter for oxygen;
  • Hematocrit is the volume that is occupied by red blood cells in the bloodstream;
  • MCHC (Mean Cell Hemoglobin Concentration) is an indicator of the density and filling of an erythrocyte with hemoglobin. Differs from MCH - the amount of HgB in the erythrocyte;
  • The study of hemoglobin density is part of a general blood test and is not carried out separately.

MCHC blood test - red blood cells and hemoglobin

The erythrocyte formula of a laboratory blood test consists of 8 different indices, is included in the general blood test (CBC) and is a fairly detailed, informative study. Among other points, the results based on the MCHC index data from the complete erythrocyte formula mean with what density hemoglobin is distributed throughout the erythrocyte, exactly how much HgB can be transported by the erythrocyte along the bloodstream to tissues and cells. In the results of the OAC, this index can be found under the name “average hemoglobin concentration”.

In the case of the density of HgB in a red blood cell, the rule “the more, the better” does not work, since hemoglobin has the task of not only binding and transporting oxygen, but also delivering the processed volume, that is, carbon dioxide to the lungs “for exhalation.” At a high concentration within the boundaries of one red blood cell, hemoglobins lose their structural quality: the thickness of the cell membrane is disrupted, and oxygen transfer becomes difficult.

Any deviation of the indicator from the norm indicates that gas exchange is impaired, and there is some problem in the body related to hematopoiesis. To find out what exactly it is, doctors turn to other tests.

What do high and low MCHC levels mean?

In a situation with a paradoxically high level of this indicator, you should not be nervous; this phenomenon cannot be called widespread. If the CBC results show a mean hemoglobin concentration that is significantly higher than 37 g/dL (or is also measured in %) it is best to first assume a laboratory error. For clinical practice, such high values ​​are very rare; hemoglobin crystallizes at such concentrations. Therefore, in such cases, a repeat blood test is always performed.

What happens at high rates

First of all, this indicates a lack of fluid and a violation of the water-salt balance. An equally common cause may be a lack of vitamins, and almost always these are representatives of group B. With a deficiency of B9 / B12 in the blood, that is, folic acid or the cobalamin group, anemia develops, better known as anemia: folate deficiency, pernicious (megaloblastic).

What does a low score mean?

This is considered a result of less than 30 (units or percent). In this case, one should suspect a deficiency of pyridoxines (derivatives of vitamin B6) or insufficient absorption of iron, its sudden loss. In women, iron deficiency can be caused by hormonal changes and associated with the characteristics of the monthly cycle and menopause. Pathological conditions - hereditary, autoimmune - can also be hidden behind a low HgB density index in the blood.

The indices for both red blood cells in other tests and HgB decrease.

Reference values ​​for hemoglobin density in erythrocytes

If the test results for the erythrocyte index are satisfactory, depending on the state of health and physical activity, preventive courses of taking micronutrients are recommended. Iron supplements and vitamin B6 are more often required; this compound actively helps the proper absorption of this microelement.

Prevention of hematopoietic pathologies is especially important for everyone who has bad habits - for example, drinking alcohol, nicotine. These toxic substances have the ability to gradually but inevitably inhibit hematopoiesis, reducing the volume of red blood cells in the blood. Among other things, alcoholic drinks have a detrimental effect on the functioning of the bone marrow, where red blood cells mature. This disrupts the delivery of oxygen to cells.

Oxygen in the body

The role of this macroelement in the body, simply put, is one: redox reactions. But such modesty is deceptive, since oxygen is the most important life-forming organogen, that is, a chemical element without which not a single type of metabolism can exist.

  • Part of proteins, hormones, enzymes, vitamins, nucleic acids and other compounds in the body, including low molecular weight ones;
  • Oxidizes carbohydrates, proteins, fats with the release of necessary energy;
  • Participates in the reaction of phagocytosis - disposal of waste cells;
  • The most important element in the launch of immune functions;
  • When there is a lack of oxygen in the blood, free radicals accumulate - molecules that accelerate cell aging and increase the risk of developing diseases, including malignant tumors (cancer).

What does hemoglobin affect?

First of all, this is a priority “delivery service” for oxygen, figuratively the highway with the busiest traffic. Each HgB molecule inside the red blood cell combines with four oxygen molecules from the lungs, then the bloodstream delivers the mixture to those tissues and cells that lack O2 to carry out the oxidative reaction and obtain the necessary energy.

In addition to this global load, hemoglobin also takes in the product of oxygen processing - carbon dioxide. Approximately 15% of the total volume of carbon dioxide (CO2) is transferred from cells back to the lungs, also by hemoglobins.

A lack of HgB creates significant difficulties with oxygen transport, which means an imbalance occurs for all types of metabolism. The pH of cells and the production of nutrients are disrupted, overall functionality decreases, but the vulnerability of cells to pathogens increases.

Lack of oxygen caused by low density and quantity of hemoglobin also leads to disruptions in the Krebs cycle:

  • this is a key, priority system that ensures cellular respiration;
  • is the final stage of energy production;
  • connection between catabolic and anabolic reactions.

In addition to this functionality, which has the highest priority in the body, it is hemoglobin that gives the blood its rich red color.

What does it mean if monocytes are elevated?

In a normal state, the number of monocytes in the blood is as follows (per 1 liter of blood):

  • for adults: from 0.04 to 0.08*109 cell units;
  • for children: from 0.05 to 1.1 * 109 cell units.

If we talk about the norm in relative terms, then the number of monocytes should be 1% -10% of the total mass of leukocytes. Moreover, for children the optimal range is from 2% to 7%, and for adults – from 1% to 8%. If the concentration is greater than the specified values, this indicates increased monocytes in the blood. This disorder is called monocytosis.

Vitamins, microelements and hemoglobin

The choice of micronutrients and the need to take complexes should be considered from different perspectives:

  • Against the background of pathological conditions

In this case, the addition of any multivitamin preparations, except those aimed at treating diseases of the hematopoietic system, must be discussed with the attending physician. Inflated hemoglobin density indicators require special attention, since additional intake of B vitamins will cause a new increase in the index or no decrease in the blood test results.

At the same time, at low levels, taking B vitamins and iron supplements is completely justified, since it is these compounds that help restore values ​​to normal.

  • Prevention and prevention of diseases

The choice of micronutrients in this case also requires preliminary discussion with a specialist who will focus exclusively on the results of blood tests. In addition to the erythrocyte index, you will need indicators for leukocytes and platelets - all this data will be reflected in the CBC.

A general study of blood quality, together with a biochemical analysis and results on the presence and concentration of vitamins, is the most informative picture of the state of health. This combination of blood tests, in addition to diagnosing diseases, is widely used in dietetics and pediatrics, and allows one to determine the actual, personal need for micronutrients.

How often should you take a general blood test?

The frequency of health monitoring is determined by the attending physician, if we are talking about the presence of diseases. In this case, there are no restrictions on taking any blood test; the studies will allow you to quickly respond to changes in your health status and change the course of treatment in a timely manner.

For everyone without abnormalities, it is recommended to repeat the CBC annually to confirm the absence of abnormalities or to detect imbalances at an early stage.

For those who do not take a passive position in matters of caring for their own health, OBC, biochemistry or vitamin tests are taken according to a plan determined by the goals of the micronutrient intake program and lifestyle.

First check-up

An indicator of health status at a current moment in time. Based on these data, not only a personal formula for the concentration and combination of vitamins and micronutrients can be developed, but also a nutritional part, a diet, if weight correction is required.

Second check-up

The life cycle of red blood cells is no more than 4 months, and there is no synchronicity in RBC renewal. To monitor the first results of taking a multivitamin complex according to an individual formula, you will need to donate blood again before the majority of the red blood cells are replaced. But you also shouldn’t rush, especially in the case of combined health support methods. The body’s reaction to changes in diet and/or physical activity 6-7 weeks after the start of the program will be exhaustively informative.

Every next check-up

The frequency of checking your own successes is determined by their severity. If the body responds sensitively to the introduction of micronutrients into the nutrition plan, the trend is very likely to continue. The date of any inspection after the second check-up in this case is set arbitrarily or every 2 months if there are grounds for additional control measures. Risk factors include primarily bad habits and excess weight. Adhering to the schedule of laboratory tests is also recommended for everyone who is faced with infectious viral diseases, injuries, and stress.

Normal parameters for different age and gender groups

The values ​​of this indicator have slight differences, which is determined by the development or extinction of metabolic processes, including the factor of blood cell production. Among male and female representatives, some differences are also noted, which, of course, is taken into account when deciphering research materials.

Thus, the boundaries of the norm are determined as follows. Children under 12 years of age. At this age, gender characteristics do not affect this indicator. In newborns, values ​​of 280-350 g/l are taken as normal. In children older than MCHC increases to 370 g/l and does not change until the age of 12 years.

Teenagers under 18 years of age. At this age, the indicators for boys and girls will differ; this is due to the onset of puberty and the characteristics of the body’s restructuring. For boys, MCHC should not exceed 380 g/l, while for girls it should not exceed 370 g/l. The latter have slightly low values, this is due to regular blood loss during menstruation.

In adult men and women of reproductive age (up to 45-50 years), the indicators do not differ significantly and can vary from 320 to 380 g/l. In older people, MCHC values ​​gradually decrease as they age, which is explained by a decrease in the activity of all processes in the body, including cell production.

Where to get tested for hemoglobin

In this case, we are talking about a comprehensive OBC test - as part of this blood test, not only the hemoglobin density in the red blood cell is examined, but also other characteristics of red blood cells. A general study is carried out in most laboratories of medical clinics; choosing the most comfortable one is a matter of habits, convenience of location, and cost.
