Successful treatment of any disease primarily depends on the establishment of the correct diagnosis. But it often happens that pathologies completely different in nature cause similar changes in the analyzes.

One such striking example is eosinophilia in a clinical blood test, which can occur both in allergic diseases and in infection with worms.

What to do in such a situation? To get started, we recommend reading this article. This article details the methods of dealing with parasites. We also recommend contacting a specialist. Read the article >>>

What is eosinophilia

This name is a condition in which the number of eosinophils in the blood increases sharply. At the same time, infiltration, or soaking of the surrounding tissues with eosinophils, is also observed. Eosinophils are a subtype of white blood cells, leukocytes.

They are responsible for many functions of the immune system, for example, they have the ability to absorb foreign cells and particles. In addition, they are actively involved in allergic processes by binding or releasing histamine. That is, they can both stimulate allergies and perform antiallergic function. Also, eosinophils play an important role in protecting the body from helminth parasites, destroying their cells.

Accordingly, both with allergies and with helminthic invasion, the production of these cells in the bone marrow increases - and a condition called eosinophilia develops. But the same duality of eosinophil functions can lead to diagnostic errors.

When to get tested for worms

At the time of the general analysis of blood and feces, high eosinophil counts are sometimes found. This is a sign that warns of the risk of parasite infestation. Although such an indicator can attract the attention of an allergist doctor.

Perhaps this allergy is caused by the presence of parasites in the body. It is also necessary to sound the alarm when a high level of hemoglobin and ESR is detected.

Symptoms similar to those with parasites in the body are usually referred to:

  • frequent colds;
  • apathy;
  • fatigue;
  • intestinal obstruction;
  • brittle hair and nails.

To identify an accurate diagnosis, it is necessary to pass tests. Modern diagnostics of the disease gives effective results. It is necessary to donate blood and feces for research, with the help of which the absence or presence of helminths is established.

These analyzes can determine:

  • types of helminths;
  • reproduction of parasites;
  • the number of helminths in the body.

It should be added that the analysis (ELISA) is the most accurate (it shows the reliability of the results by 96%). In addition, research makes it possible to diagnose at an early stage and create the right approach to the treatment of parasites.

Indicators of eosinophils in hematological examination

A general blood test for worms (hemotest) allows you to determine the number of eosinophils (a type of leukocytes), which fight a foreign protein. As soon as worms appear in the body, the level of eosinophils increases sharply, signaling that the body is susceptible to infection.

In addition, the state of immunity, symptoms, the presence of complications, which also affect the indicator of the number of cells, are taken into account.

The condition of the body in which an increase in the level of eosinophils is observed is called eosinophilia. The intensity of this condition is directly related to the form of symptoms.

The number of eosinophils in the blood increases with helminth infection. An indisputable sign of helminthiasis is the level of eosinophils greater than 8%, at a rate of 1–5% of the total number of leukocytes.

Biochemical research

Blood biochemistry is a clinical research method that allows one to judge the state of most internal organs and body systems, reveals the presence of infections, including helminthic invasions.

This analysis examines the following components:

  • glucose;
  • total / direct bilirubin;
  • aminotransferases - AST and ALT;
  • alkaline phosphatase;
  • indicators of total protein;
  • cholesterol.

To detect the presence of worms, a comprehensive biochemical analysis is prescribed with the diagnosis of all indicators.

Eosinophils in a blood test for roundworm

Ascariasis is a helminthic invasion that is caused by human ascaris. This is a fairly common disease, especially among children. The analysis for roundworm is an important stage of diagnosis, the timely implementation of which helps to prevent the development of complications of ascariasis.

A man, in whose intestines females and males of Ascaris parasitize, is the only source of invasion. Adult roundworms live in the small intestine, where females, after fertilization, lay about 200,000 eggs per day. Getting into the environment with faeces, under favorable conditions, the eggs ripen for 10-15 days or more.


When a person swallows mature eggs, larvae emerge from them in the upper part of the small intestine, which penetrate through the intestinal wall into the inferior vena cava, then into the vessels of the liver and lungs, from where they pass into the alveoli and bronchi.

In the lungs, they rise along the epithelium of the respiratory tract into the pharynx and are swallowed into the gastrointestinal tract.

After re-entering the small intestine, they develop within 70 to 75 days into adult parasites capable of producing eggs.

The lifespan of an adult roundworm reaches a year, after which it dies and, together with feces, it is removed outside. Therefore, the presence of ascaris in one person for several years is explained only by repeated infections.

In the clinical course of ascariasis, two phases are distinguished - early (migratory) and late (intestinal). The first phase coincides with the period of migration of the larvae, while the second is due to parasitism of helminths in the intestines and possible complications.

The main clinical signs of ascariasis are symptoms of lung damage (dry cough, shortness of breath, chest pain), low-grade fever, urticaria, itching, malaise, weakness, headaches, eosinophilia up to 20-30%, hyperleukocytosis.

In the chronic phase of ascariasis, nausea, intestinal dysfunction, abdominal pain, and sleep disturbances occur. Possible complications of ascariasis: pancreatitis, appendicitis, intestinal obstruction.


The identification of an increased number of eosinophils in a clinical blood test may be evidence not only of allergies or helminthic lesions. Eosinophilia can develop with many other diseases. After all, clinical practice and laboratory studies prove that an increase in this indicator is not specific to any pathology.

Its identification should only alert the doctor, force him to prescribe additional, more thorough and highly specialized examinations to the patient. Therefore, before starting treatment for helminthiasis, allergic or any other disease, it is imperative to accurately determine the cause of the increase in the number of eosinophils.
