- Formerly called clinical (CBC) now - a general blood test - the fastest and most informative testing; a quick and informative screening that reflects the state of health;
- The analysis examines the number of blood components, their ratio and the general specificity of the elements - hemoglobin, red blood cells, leukocytes, platelets;
- The abbreviation for leukocytes in the results is WBC (White Blood Cells, white blood cells - translation from English);
- The role of leukocytes is immunity, resistance to pathogens, disposal of tissue destruction residues (phagocytosis).
WBC blood test – immunity and leukocytes
A general blood test may contain up to 25 parameters for assessing its quality and composition. It is white blood cells (cells) that receive more attention, and to obtain a detailed informative picture of leukocytes, about 20 blood test indices are used: these are the relative and absolute content of subpopulations of white blood cells. These include basophils, neutrophils, eosinophils, lymphocytes and macrophages of the mononuclear system.
Leukocytes are the main markers of any inflammatory process, the body’s immune response to internal and external interference: tumor, allergen, infection. The task of white blood cells is to neutralize pathogens, foreign components and their own cells that have exhausted their resources.
To diagnose acute systemic diseases and inflammation, a detailed study is prescribed: leukocytogram, leukocyte formula. The need for such blood tests arises, for example, in case of anemia (anemia), tumors, poisoning, during the diagnosis and treatment of pathological processes of a bacterial or viral nature, etc.
To monitor health status, among other indicators in the list of UAC tests, a shortened study is sufficient: the content of individual formed elements in the blood and their morphology. Basic information about the absence of an increased load on the immune system is provided by calculating the mass of white blood cells, this is determined by the calculation of WBC - White Blood Cells.
Regardless of whether the WBC value is decreased or increased in the general analysis, any deviation indicates a reaction of the immune system, and it occurs against the background of any disease or pathological process.
Low and high white blood cell count
White blood cells are the first line of defense in the body. An increase in the level of WBC in the blood indicates atypical activity of the immune system and the need to look for the cause that caused the mobilization of protective forces. A low WBC threshold is evidence that the body’s immune capabilities are running out.
The weight and ratio of WBC varieties in the blood fluctuates not only due to diseases or injuries of a different nature. Any changes in the total volume of white blood cells, an increase or decrease in the indicator, are also influenced by temporary conditions:
- Bleeding – including during the monthly cycle in women;
- Poisoning – food, medicine, alcohol, toxic substances;
- Injuries – burns, cuts, dislocations, fractures, etc.;
- Various procedures - therapeutic, surgical, hardware cosmetology;
- High physical activity or a sharp increase in its level;
- Stress – an imbalance in the mental and/or emotional state, including destructive long-term experiences (distress);
- Lack of vitamins, especially B12 (cobalamins) and B9 (folic acid), micronutrient deficiency.
Monocytosis
Monocytosis is a condition in which the number of blood monocytes exceeds the standard. The norm is from 2 to 9%. This may indicate:
- Specific infections with a long course (tuberculosis, chlamydia, viral and bacterial diseases);
- Parasitic infestations;
- Monocytic type of leukemia;
- Lymphogranulomatosis and other types of lymphomas;
- Autoimmune diseases;
- Infectious mononucleosis;
- Condition after removal of the spleen.
A decrease in the level of monocytes practically does not occur.
Additional blood tests for leukocytes
If we talk about the choice of additional cellular nutrition programs - micronutrients - the data in the WBC analysis is only enough to understand whether an inflammatory process or disease is currently developing in the body. The WBC data does not influence what exactly the vitamin complex should be. However, it is the CBC that shows the level of white blood cells and helps determine the further path to study the composition and quality of blood.
The results for white blood cells can be clarified by deciphering the leukocyte formula in the composition of the UBC, also called a leukogram shift and studying the percentage of all types of WBC:
- To the left – a regenerative shift, the release of young, immature WBC into the blood. A sign of inflammation, excessive physical activity, poisoning, bleeding;
- To the left with rejuvenation - indicates the undesirable presence of cells in the blood that normally should only be found in the bone marrow. It is necessary to examine for chronic and acute diseases: leukemia, spread of metastases, myelofibrosis, etc.;
- To the right - degenerative shift, lack of production of new WBC. It is at this point in the leukocytogram that one can suspect a lack of vitamins B9 (folate deficiency anemia) B12 (anemia with a lack of red blood cells, polyneuropathy). Also – kidney disease, liver disease, reaction to blood transfusion.
Analysis for vitamins and microelements
Against the background of a low WBC level, it is recommended to add to the blood test a comprehensive study of the concentration of key micronutrients - important participants in the formation, development, and regulation of the immune system. The reason for the decrease in the level of white blood cells can most likely be vitamin deficiency or the intake of an unbalanced complex of additional cellular nutrition, especially if inflammatory processes and diseases are excluded.
This blood test is called “Basic micronutrients of immunity”, also can be referred to as Vitamins and trace elements, Immune response. It is a fairly informative addition to the OAC, clarifies the reasons for the deterioration of well-being when there are no diseases, injuries or other obvious reasons for reducing the level of leukocytes.
Eosinophilia and basophilia
An increase in the number of eosinophilic leukocytes, which are designated EOS in the WBC analysis, is when the resulting figure exceeds 5%. This is possible when:
- Allergic reactions;
- Skin diseases (atopic dermatitis, psoriasis, eczema);
- Worm infestation;
- Autoimmune processes;
- Some infections (scarlet fever);
- Eosinophilic type of leukemia.
The norm for basophil content is no more than 1%. These cells are usually not detected by WBC analysis. Their appearance may occur in some forms of myeloblastic leukemia.
What vitamins and microelements are necessary for immunity?
A complex multi-stage system protects our health at different levels: from skin integrity to humoral and cellular reactions involving lymphocytes - one of the subtypes of leukocytes. The action of micronutrients is also aimed at supporting various functions in the body. For example, vitamin A is responsible for skin condition, phagocytosis and stimulation of immunoglobulin production; group B compounds provide and maintain the activity of red (erythrocytes) and white blood cells. Each element not only has its own function, but also has a close relationship with many others.
Priority participants in the regulation of the immune system
Vitamins
-fat-soluble (accumulate) – A, E, D3, K2;
- water-soluble (do not accumulate, systematic intake is required) – C, B9, B12, B5, B6;
Micro- and macroelements
-Iron (Fe) – is part of the WBC activators, increases the saturation of tissues with macrophages (antibacterial protection);
-Zn (zinc) – stimulates phagocytosis, antimicrobial defense (including viruses);
-Cu (copper) – macrophage activator;
-Mn (manganese) – protection of the cell membrane;
-Se (selenium) – potentiates both cellular and humoral responses;
Change in lymphocyte level
Lymphocyte cells, like neutrophil leukocytes, provide immune surveillance in the body. But in contrast to them, lymphocytes are responsible for both cellular and immunoglobulin immunity. Their norm is 18-40%. Explanation of possible results of WBC analysis is given in the table.
| Lymphocytosis (increased blood lymphocytes) | Lymphopenia (decreased blood lymphocytes) |

WBC blood test is an excellent alternative to the classic study of its leukocyte composition. The main thing is to know the subtleties of correct interpretation of the results obtained.
How often should you take a leukocyte blood test?
It is recommended to monitor WBC parameters as part of a general laboratory blood test at least once a year if the state of health is satisfactory and the tests themselves do not have diagnostic value.
If we are talking about somatic diseases or in cases where caring for one’s own health is based on the principles of expediency, within the framework of evidence-based medicine, the frequency of blood tests and laboratory tests is determined by a doctor or a certified nutritionist or dietitian. It is on the study of the individual characteristics of blood and further on its composition, the body’s response to micronutrients that the bioniq system for assembling personalized vitamin complexes is built.
Where to get tested for leukocytes
It is the CBC, abbreviated or with a leukocytogram, that can be done by any laboratory; the quality of such blood tests will not differ. The issue is a little more complicated with studies of vitamin levels, since there is no single form for such a task. In each case, the doctor prescribes a list of microelements and vitamins that are priority for study.
For example, you can donate blood specifically for the group of fat-soluble vitamins or group B. Microelements are most often studied according to the following list: iron, magnesium, manganese, calcium, zinc, copper.
The choice of tests is made on the basis of personal complaints about health or regarding a specific purpose for collecting information.
For this purpose, bioniq has developed comfortable programs for assembling personalized bioniq LIFE and bioniq BALANCE micronutrient complexes, with the ability to collect material at home or in a place convenient for you.
