Parasites are organisms that live off a foreign organism, feed on its resources and harm it with their vital activity.

According to statistics, about 95% of people on Earth are infected with parasites, and even in developed Europe, parasites are recorded in every third inhabitant.

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 >>>

One person can suffer from five or more types of parasites at the same time. Therefore, in order to timely diagnose parasites and start treatment, you need to know what the tests for worms are called and where they can be taken. You can read more about the tests for parasites here.

What are the tests for parasites

Detection of the presence of helminths in the body allows the study of blood and feces. The analysis of feces is carried out in order to detect the eggs of worms and allows you to determine the presence of a helminth and its type (pinworms, tapeworm, etc.).

Since the active vital activity of the parasite is manifested by the release of toxic substances and sensitization of the body, characteristic changes in the blood formula can be seen in the analysis.

A complete blood count helps detect an increase in the level of eosinophils and, less often, anemia. This study allows one to suspect or confirm the presence of a parasitic disease without specifying the type of parasite.

Stool analysis is not always informative. The absence of worm eggs in the feces gives grounds to exclude only some types of helminthiasis. To detect other parasites, a blood test is carried out for antibodies to them (echinococcus, opisthorchia, trichinella, etc.).

What are blood tests for worms called?

In medical practice, blood tests for worms are called as follows:

  • General blood analysis;
  • Immunological method (ELISA);
  • Hemoscanning;
  • Serological analysis;
  • PCR diagnostics.

General blood analysis

First of all, in a general blood test, attention is paid to the manifestation of anemia and the number of eosinophils (a subspecies of leukocytes).

Eosinophils are capable of destructive action on foreign cells, therefore they take an active part in the anthelmintic process. But at too high a concentration they can cause allergic reactions. The number of eosinophils above the norm indicates helminthic invasion, including.

Also, blood for helminths shows the following results:

  • Decrease in hemoglobin with a simultaneous decrease in erythrocytes (anemia);
  • Increased protein content;
  • Increased content of immunoglobulins;
  • A high level of IgE antibodies responsible for the antiparasitic effect, which causes the appearance of allergic reactions.
  • Eosinophilia detects the following types of worms by blood analysis: toxocara, roundworms, intestinal acne, hookworms, nekator.

So, when toxocaras are damaged, the level of eosinophils increases by 30 and even 90% of the norm, and this state may not change for several months and years.

Anemia is a sign of infection with roundworms, broad tapeworm, whipworm, bovine tapeworm, pork tapeworm.

Regardless of how the blood test for worms is called, its main purpose is to assess the effect of worms, their vital activity on the composition of the blood.

ELISA

ELISA, and is aimed at identifying antigens to certain parasites. Modern diagnostics allows you to carefully examine the blood and determine:

  • A kind of helminths;
  • How developed is the parasite's reproductive capacity;
  • The degree of infection.

The study for antibodies to helminths is by far the most accurate, it gives a reliable result in 95% of cases. An antibody test can be performed early in the course of infection, starting from the fifth day after infection.

As a result of the determination of antigens and antibodies, an effective treatment can be selected. This study allows you to identify the most common types of parasites:

  • Ascaris;
  • Giardia;
  • Trichinella.

Also, hemotest allows you to determine the following parasitic diseases:

  • Teniosis;
  • Opisthorchiasis;
  • Fascioliasis;
  • Amoebiasis.

The analysis coding is included in the count of the antibodies JgM, JgG and JgA. To determine the stage of invasion, it is necessary to know what these or other results are talking about.

If all three antibodies are not present in the organization, then the result will be considered negative (JgM (-), JgG (-), JgA (-)). This means that a person has a stable immunity to parasites. If immunoglobulin G is found to be positive (JgG (+)), then this will mean that the person has recently had this infection.

If the result is as follows - JgM (+), JgG (- / +), JgA (- / +) - this means that the disease is in the acute phase. The result JgM (-), JgG (+/-), JgA (+/-) indicates that the person has acquired a chronic form of this disease. The result JgM (+), JgG (+), JgA (+) indicates an exacerbation of this infection. If immunoglobulin M is negative (JgM (-)), then it will indicate a complete recovery.

Hemoscanning

What is the fundamental difference between the blood hemoscanning method (blood scanning using a dark-field microscope) from the traditional clinical blood test?

The analysis is carried out immediately, in the presence of the patient, at a very high magnification (approximately 1000-2000x) on a dark-field microscope connected via a video camera to a computer monitor. This enables the patient to see all the processes in his blood in real time during hemoscanning.

The nutritionist who performs the hemoscanning explains what is happening on the monitor screen to the patient.

The dark-field microscope and the hemoscanning method allow for analysis at a magnification of over 1000x, which allows you to see the state of the corpuscular elements of the blood: erythrocytes - their shape, contours, mobility, their "stickiness" (the process of sludge blood cells).

Hemoscanning clearly shows (visualizes) the state of platelets, lymphocytes and blood leukocytes in dynamics.

With hemoscanning, you can visually assess:

  • Helminth larvae;
  • The presence of other parasites;
  • Blood plasma condition;
  • Cholesterol crystals
  • Uric acid salts;
  • The presence of crystals of orthomonophosphates (a sign of calcium deficiency);
  • The presence of bacterial flora;
  • The presence of fungal flora in the blood;
  • The presence of yeast flora;
  • Helminth larvae.

Serological analysis

This is another kind of research. This method is used when it is necessary to identify protozoa and multicellular parasites not only in children, but also in adults. For research, not blood is taken, but serum.

During the analysis, antibodies to various parasites are determined. Serological research even allows you to establish which infectious diseases the body has already had to deal with recently.

Despite the good information content, this study has a drawback, it does not always make it possible to determine the stage of the disease, and it can be difficult to make an accurate diagnosis. Therefore, it is necessary to carry out it again after 10-14 days. After comparing the results, a conclusion is reached.

PCR diagnostics

PCR diagnostics (polymerase chain reaction) is a high-precision method for diagnosing numerous infections and helminthic invasions, which is based on the study of human genetic material (DNA and RNA).

Depending on the purpose of the study, blood, saliva, sputum, genital secretions and other biological materials are used. It often happens that parasites of different nature can cause the same symptoms of the disease.

What is the name of the analysis of feces for worms and their eggs

The following types of fecal examination for the presence of parasites are distinguished:

  • General analysis of feces for eggs of worms;
  • Scraping for enterobiasis.

General analysis of feces for eggs of worms

The analysis of feces for helminth eggs is a microscopic examination, the purpose of which is to detect parasites in the lower parts of the digestive tract.

An example of a form for passing an analysis for eggs of worms

This laboratory test is performed when:

  • Carrying out a medical examination or registration of a patient for treatment in a hospital,
  • The presence of symptoms of helminthic invasion,
  • The child's admission to kindergarten or school,
  • Obtaining a certificate in the swimming pool or a medical book.

Features of the analysis of feces for helminth eggs:

  • With ascariasis - microscopic examination reveals the eggs of parasites in the intestinal stage of the disease. In the migration phase, ascaris larvae are found in sputum, and in the blood - an increased level of specific antibodies. If Ascaris eggs are found in the duodenal contents, then this indicates the presence of parasites in the bile and pancreatic ducts;
  • Enterobiasis (pinworms) - a study of scraping from the perianal folds is carried out. The diagnosis of enterobiasis is established in case of detection of pinworm eggs or the helminths themselves. The study is carried out three times, with an interval of 3-7 days;
  • Giardia Lamblia - repeated microscopic examination of feces. Warm stool should be examined once a week for a month. In modern conditions, highly sensitive test systems have been developed that allow the detection of total antibodies in the blood, antigens of lamblia cysts in feces by ELISA. It is possible to detect vegetative forms and cysts of lamblia with microscopy of bile in 50%;
  • In case of strongyloidosis, control of the effectiveness of treatment is carried out only by examining bile (even if the parasite was detected in the feces) 1 month after treatment.

Scraping for enterobiasis

The analysis of feces for enterobiasis should be taken from three different sites so that the result is as accurate as possible. The collected material is immediately delivered to the laboratory. In order to deliver the feces to the laboratory, from where it will be sent for research, you need to purchase a special plastic container with a lid.

Feces should be donated several times, since it is not always possible to find parasite eggs in it. In order for the analysis to be as accurate as possible, before collecting feces. do not wash.

Additionally, a blood test is performed, which is able to show anemia and eosinophilia in the presence of helminths.

Even if you know how to correctly take an analysis for enterobiasis, and how to collect feces for this analysis, the results may not be enough to establish an accurate diagnosis. In such cases, if the patient has all the signs characteristic of worm infestation, an analysis is made for enterobiasis using PCR.

Girls and women may be assigned an examination by a gynecologist to exclude inflammation in the genitals. But the most reliable of all is the study of fresh scraping for enterobiasis. It is recommended to pass scraping for enterobiasis at least three times with an interval of two weeks between them.

What are the children's tests for parasites

Typically, children are infected in the same way as adults. Then the helminths heavily attack the child's body and cause symptoms the same as in adults. Therefore, in order to detect helminths in a child, you will need to see a doctor and take blood and feces for analysis. Therefore, children's tests for worms will be called the same as in adults.
