The need to pass tests for parasites in children arises in the case of comparative diagnostics in order to establish the type of worm, as well as during a preventive examination of the child. Having penetrated the body, parasites can not only be localized in the intestines - some of them have the ability to spread throughout the body and get into any internal organs with blood flow.

Situations in which it is recommended to take tests

There is a certain list of symptoms, the appearance of which should prompt parents to examine their child for the presence of helminthic invasion. Such manifestations include:

  • excess saliva;
  • nausea, which appears quite often;
  • lack or increased appetite;
  • headache;
  • dizziness;
  • discoloration of the skin - it becomes pale;
  • darkening of the skin under the eyes;
  • bowel disorders (diarrhea or constipation);
  • regular and sudden pain sensations without clear localization;
  • itching in the rectal sphincter area;
  • grinding of teeth that occurs at night during sleep;
  • the appearance of a rash of a varied nature and localization.

If at least a few of the symptoms listed above are observed, you must immediately consult a doctor and pass the appropriate tests, and not only the child, but also all family members. Tests that help identify parasites in the body include:

  • study of feces for the presence of helminth eggs in them;
  • scraping - with a disease such as enterobiasis;
  • linked immunosorbent assay.

Stool examination

Stool analysis is considered the most affordable, simple and common method for detecting parasites. It is through its implementation that it is possible to confirm or refute the diagnosis of the presence of a helminthic invasion in a child. Also, using the analysis of feces, it is possible to carry out a differential diagnosis of the disease if an infection with microorganisms that belong to the group of protozoa has occurred.

To make the result more accurate, it is recommended to donate feces for this study several times, observing a certain time between analyzes. The fact is that for some time, adults of helminths may not emit eggs.


Feces analysis requires some preparation.

At least a week in advance, you must stop taking the following medications:

  • antibiotics;
  • remedies for helminths

  • laxatives;
  • drugs that have the ability to eliminate the manifestations of diarrhea.
  1. If necessary, endoscopic examinations of the lower intestine can be carried out at least fourteen days before stool delivery.
  2. The material must be taken in small quantities from several sites.
  3. The sampling of the test material should be carried out in a dry and clean glass or plastic container with a lid.
  4. No more than a day should pass from the moment of sampling to the statement of the material in the laboratory. But there are parasites, for the detection of which the study of feces should be carried out no later than thirty minutes after sampling (for example, with giardiasis).

Immunoassay studies

The most accurate of all examinations of children for the presence of helminthic invasion is considered serological, which is called an enzyme immunoassay. The test material in this case is venous blood. With the help of this study, it is possible to identify the presence of antibodies in the body, the appearance of which indicates a pathogenic agent.


The advantages that appear when conducting this study include the ability to:

  • identify helminths, even if their number is insignificant;
  • determine the type of parasite with a high level of accuracy;
  • find out the quality of the medical therapy carried out.

To donate blood correctly, you must follow these guidelines.

  1. You need to donate blood before starting treatment.
  2. Blood donation must be done in the morning and on an empty stomach (only drinking water is allowed).
  3. Food overload should be avoided on the eve of testing. You need to eat food no later than 8 hours before blood sampling.
  4. Seven days before blood sampling, you must stop taking any medication. If such an action is considered impossible, then the laboratory workers must be notified of the acceptance of a certain type of agent.

The pediatrician makes a diagnosis based on the results of the analysis, by assessing the clinical picture and collecting anamnestic data. It is a serological study that allows you to determine the type of pathogen and prescribe an adequate and effective treatment.

Diagnostic scraping

You can use cotton swabs to collect the test material. It is recommended to collect material after sleep (in the morning), before visiting the toilet and taking water procedures.


The procedure itself must be carried out with caution with a cotton swab, which should be dipped in glycerin. It should be carried out in the anal area, around the rectal sphincter. After that, the cotton swab must be placed in a glass or plastic test tube and closed with a lid. The collected material should be delivered to the laboratory on the same day.

With the help of this study, you can quickly identify worms. It is recommended to take scrapings for enterobiasis every six months. For the diagnosis to be reliable, and doubts to be removed, it may be necessary to re-take the material after two or three days.

Be considerate of your children

It is children who need attention and care, so parents should be aware of the unpleasant health problems of a child that can occur.

It is important to know what types of helminths are, and what tests you need to pass to find them. Follow the recommendations and be healthy at all times.
