A complete blood count is a standard procedure that every person has undergone in life. When passing the analysis, a result is formed that demonstrates the number of cells in the blood and any deviations in the readings. Blood is analyzed for any disease, mild or complex. Also, medicine recommends to undergo this standard analysis on a regular basis, without unpleasant symptoms or discomfort.

Thus, you can prevent the appearance of the disease or not bring it to a complex form. Changes in performance rarely occur strongly, but this is enough for a person to feel bad.

Blood sampling usually takes place early in the morning and on an empty stomach. For a general analysis, capillary blood is taken from a finger, where it is considered more purified and the indicators will be more accurate. There is no specialized preparation for donating blood.

It is necessary to donate blood on an empty stomach so that the indicators are not changed when eating. Blood from a vein is taken less often for analysis and it is aimed at obtaining other results and studying other indicators.

Interpretation of analyzes and their accuracy


Deciphering of analyzes occurs in several stages, each of which is considered with different special equipment. Modern laboratories are equipped with the latest technology and show results with incredible accuracy.

But even with a slight change in the indicator, the patient does not need to panic, there may be a sharp jump in indicators against the background of a hormonal surge or taking some products. For recognition, you should re-pass the analysis and study the dynamics of indicators.

The analysis can be taken on the referral of a doctor, if you feel unwell, or if you suspect a disease, or you can examine yourself, this is approved by medicine. But already the deciphering of the analysis should be dealt with by an experienced specialist with a medical education, since he must diagnose the disease and then prescribe drugs, carry out treatment.

During the decoding of analyzes, many indicators are studied, each of which occupies a special place, performs a specific function and their level must correspond to the required norm in the body. It is during deviations from the norm that their number changes and metamorphoses occur in the human body.

The main constituents of blood


Blood consists of main and auxiliary indicators, with its own characteristics and functions. If the indicator is normal, then no worries arise, but at the first symptoms, you need to contact the clinic for an appointment for tests.

The main indicators in the blood:

  1. Erythrocyte is a red blood cell that occupies a large mass of the entire blood composition and is the main element that performs the main functions in the blood. Red blood cells are involved in the supply and delivery of oxygen to all cells of the human internal organs, skin and brain. They also purify cells from carbon dioxide and release it out of the body through the lungs. If the red blood cell count is significantly increased, there is a risk of sticking them together and clogging the blood vessels, which is deadly for humans.
  2. Hemoglobin is a special combination of proteins and fats that forms a useful and essential blood composition. Hemoglobin takes place in the erythrocyte cell and is directly involved in the movement of oxygen through the human body. A decrease in the required level contributes to the appearance of anemia - oxygen deficiency, and an increase in this indicator indicates a lack of fluid in the body.
  3. Hematocrit is an indicator that is reflected as a percentage, and it shows the proportion of red blood cells in the blood to the total plasma. A decreased level also indicates anemia, and an increased level indicates a lack of fluid.
  4. The platelet is an equally important indicator responsible for blood clotting. If a capillary or vessel is damaged or cut, blood flows out through the wound, and it is this cell in the blood that is responsible for stopping the flow and the formation of a thrombus in the wound. Here, deviations in the rate of the indicator should also not be allowed. When it decreases, the blood becomes liquid and with a large wound, it is difficult to stop its flow and you can lose large volumes of vital fluid. And with an increased level of platelets, clogging of not only wounds, but also vital passages in the veins and heart muscle can occur.

The role of leukocytes in the blood


Leukocytes or white blood particles are elements responsible for the body's defense, and show the level of the state of the human immune system.

The leukocyte meaning is to form the body's defense against viruses, infections, bacteria and toxins. Each leukocyte cell has its own purpose and each has an indicator of the norm of leukocytes in human blood.

Leukocytes in the blood and their norm is a very imprecise concept. Since at different ages and state of the body, the norms of leukocytes are constantly changing.

Leukocytes are always present in blood cells and their rate is unstable. It strongly depends on age, diet and even the time of day. But the rate of leukocytes in the blood practically does not change from gender.

Leukocytes consist of the so-called subgroups, each of which has its own function and occupies a certain rate in the blood: neutrophils, lymphocytes, monocytes, basophils and eosinophils.

If the test result obtained exceeds the normal number of leukocytes, this indicates an increased protective level of the body and a readiness to resist with bacteria. But the lowered level makes the doctor and the patient worry about the state of the body. When the white blood cell count drops, the body may not be able to cope with some of the attacks of infection.

There are several main reasons for lowering this indicator:

  1. There may be a lack of young cells to create an updated system of leukocytes, this also indicates a low level of erythrocytes and hemoglobin. To avoid this, you may need to follow some kind of diet and medication support for the body.
  2. In the case of a very poor environmental situation in the place of residence of a person, there may be a strong decrease in the leukocyte count. Since they are constantly being released to combat toxins and toxins in the environment.
  3. In the treatment of oncological diseases, chemotherapy, in addition to malignant cells, there is also a killing and positive. Leukocytes die at the stage of development and significantly reduce immunity, thus, a person becomes extremely vulnerable.
