Eosinophils are normal or reduced in blood.

Eosinophils are a type of white blood cell whose action is to destroy the foreign protein in the blood. After appearing in the bone marrow, eosinophils move for several hours into the blood stream, and from there migrate to tissues, where their main vital activity takes a week or two. Norm of eosinophils in the blood indicates the absence of allergic, inflammatory and oncological diseases. But even if the amount of eosinophils in the blood does not correspond to the norm, it can be interpreted in various ways. Today we will talk about what eosinophils are in the blood test and what their level says.
- From birth to one year: 1-6%
- From one year to two: 1-7%
- From 2 to 4 years: 1-6%
- Over 4 years old - 1-5%
The absolute index is not so often taken into account, because it is the ratio of leukocytes that is important for diagnosis, the so-called leukocyte formula.109 / l)
Eosinophils above normal
What does this mean? Eosinophils primarily cause an allergic readiness of the body, because the appearance in the blood of foreign protein, against which the action of these blood cells is directed, is due to the presence of an allergen.
A condition in which there are more eosinophils in the blood than is necessary, according to the norm, is called eosinophilia.
Here is what an increase in eosinophils may indicate:
- Allergy( including medications. For example, aspirin use provides for such a side effect).
- Magnesium deficiency;
- Infection with parasites;
- Chronic gastrointestinal diseases;
- Congenital heart disease;
Not always eosinophilia is a bad sign, during an infectious disease, a slight increase in eosinophils indicates a successful treatment.
Depending on the level of growth of eosinophils, there are three degrees of eosinophilia:
- Light( up to 10%);
- Moderate( 11-19%);
- Pronounced( above 19%).
Obviously, at a rate of 1-5%, eosinophils 8 in an adult are related to a pronounced degree of deviation.to contents ↑
Eosinophils are reduced
The phenomenon opposite to the increase in eosinophils is called eosinopenia. In other words, it is a decrease in blood eosinophils. Most often, it is judged on the exhaustion of the body. The causes of eosinopenia may be as follows:
- Infection in the body;
- Injuries and burns;
- Postoperative period;
- Severe purulent infections, sepsis;
- Myocardial Infarction;
- Heavy metal intoxication;
- Constant stress;
- Lack of sleep;
- Adrenal and Thyroid Pathologies;
Eosinopenia, in which the level of cells reaches 0, characteristic of typhoid fever, acute appendicitis, desentery.
If a person constantly sleeps a little, works a lot and is nervous, and as a result of a blood test, eosinophils are lowered in an adult, the reason is to be found in the lifestyle review.
Do not overlook the fact that blood tests for eosinophils may be inaccurate, if there is a suspicion that the result is erroneous, donate blood to another laboratory.
Low eosinophils in the blood are less common than elevated ones, and often they are not of high importance for diagnosis. But at the same time, eosinopenia may be one of the factors that determine the presence of severe pathology in the complex.
So, if eosinophils are lowered in a child, and the decrease occurs smoothly, but constantly, the doctor may suggest Down Syndrome. Premature babies also have a lower level of eosinophils compared with that for their age.
The fact that eosinophils are lowered during pregnancy usually does not go beyond the normal range. During the term of carrying the child, the body partially blocks the immune defense to prevent the fetus from rejecting as a foreign object. In this regard, the numerical amount of eosinophils is also reduced.
During childbirth, their level may drop to zero. This can be explained by strong pains, spasms and stress for the expectant mother, these factors, which usually cause eosinopenia, are combined with each other. Over time, after the birth of a child, the level of eosinophils is restored and returns to normal.
Often, changes in eosinophil levels are associated with fluctuations in the number of other blood cells. This helps the doctor more accurately suggest a diagnosis.
One of the most severe cases of changes in the number of eosinophils is eosinophilic leukemia. But the diagnosis of this disease cannot be based on a single blood test. Before making a conclusion about the presence or absence of leukemia, the doctor prescribes a versatile examination of the body.
By regularly taking a blood test, you reduce the risk of running diseases and get more chances to keep your body and blood in a healthy state. But a competent, responsible patient, along with timely blood donation, should be able to independently understand the result obtained in order to speak the same way as the attending physician.
