What is a smear from the nose to eosinophils? What are the indicators of the norm? After reading our article, you will find answers to these and other exciting questions.
The human body is made up of many organsand systems. Each has its own function, which is necessary for the overall coordinated work of all organs. Elements such as eosinophils also have their significance in the process of vital activity of the human body. They belong to the leukocyte subspecies. To determine their quantity, the patient is sampled and analyzed for a smear from the nose.
Value
Eosinophils are the elements thatare created from the bone marrow, namely from stem cells. They are granulocytes that do not divide. In order to form eosinophils, it takes several days. The whole process of their formation takes 3-4 days.
After they were formed in the bone marrow,eosinophils separate from it and circulate in the blood of a person. There they are about 6 hours. Although some people have longer, it all depends on the individual characteristics of the person. The life cycle of eosinophils is 2 weeks. After these elements enter the blood, they pass into such parts of the body as the gastrointestinal tract, lungs and subcutaneous tissues. Here they remain until the end of their life.
Eosinophils are of particular importance for the functioning of the body. They participate in the following functions:
- These elements destroy helminths.
- They have the property of absorbing foreign elements and particles that enter the human body.
How much should be present in the body? Smear from nose to eosinophils: norm
In order to determine in what quantityor other elements are contained in the human body, it is necessary to donate blood for its analysis. To count the number of eosinophils, you can take sputum for analysis. She is in the nasopharynx of the patient. You can also learn to do a smear from the nose to eosinophils.
There are standards for the norm of this type of leukocytes. For a healthy child, whose age is under 13 years, it is 0.5-7%. An adult is considered to be the norm from 0.5 to 5%.
Deviations
Renting a swab from the nose on eosinophils, remember thatthe results should be close to the minimum value of the norm. In the case when they are elevated, then, as a rule, this means that a person develops a rhinitis or has an allergic rhinitis. The increase in eosinophils in this type of analysis suggests that the common cold is of an allergic nature, not an infectious one.
It is important to know that if a person is healthy, then innasal mucosa eosinophils should not be present. In this case, the smear from the nose to eosinophils should show the minimum value of these elements. But if the indicators exceed the norm, this means that there is some pathology in the human body.
In the case where the level of eosinophils is exceeded inlarge amounts, this is a clear sign of a respiratory allergy at a neglected level of the disease. Also, similar changes indicate that in the human body there is bronchial asthma.
In addition, for this type of analysis, the presence of ascarids in the body can be diagnosed.
What diseases can be diagnosed if eosinophils are elevated?
A nasal swab can show that the valuesexaggerated. What does it mean? This phenomenon in medicine is called eosinophilia. The organism in this state can be at the stage of development of the diseases listed below:
- Allergy. As a rule, in this case, skin and respiratory tracts are affected. If the allergy is not treated and goes to a neglected form, then eosinophils spread into the lungs and complicate their work.
- Periarteritis of the nodular type.This disease is characterized by the fact that the muscle arteries of the human body die. This disease is more likely to affect middle-aged men. They begin to worry about such symptoms as abdominal pain, skin rashes, fever, kidney pathology, weight loss, joint pain.
- Leukemia can be diagnosed in children in the form ofmyeloid leukemia. This disease is characterized by the fact that the patient has heart failure. This is due to the fact that the valves of the heart are affected. If suspected of this disease, a swab of the nose (eosinophils) in children is taken.
- The presence of parasites affects the increase in eosinophils. Since their main task is to fight against extraneous elements that appear in the human body.
In addition to the above pathologies, the leveleosinophils in the human body can affect the intake of medications, or infection. For a precise diagnosis of the disease, other types of research may be needed.
Conclusion
Now you know what a smear from the nose to eosinophils is, why it is done. Also, the article specifies the rate of this indicator, and describes what is the deviation from the norm.
