Video: How And When To Get Your Child Tested For An Ovarian Leaf
How and when to get your child tested for an egg leaf
The test for helminth eggs, which in medicine is called the test for ovum leaf, is the most important method for diagnosing parasitic diseases in children. This accessible and informative method allows you to quickly identify ascariasis, enterobiasis and some other types of helminthic invasions in a child.
The test for helminth eggs, which in medicine is called the test for ovum leaf, is the most important method for diagnosing parasitic diseases in children.
When to take
Doctors prescribe a test for worm eggs for children who have symptoms of helminth infection (severe itching in the anus, nausea, vomiting, abdominal pain, weight loss with increased appetite, etc.). It is recommended to undergo a diagnosis if a small patient had close contact with a person who suffers from one or another type of helminthiasis.
It is also required to pass the test for an egg leaf for a child in preparation for admission to a children's educational, leisure or health-improving institution (kindergarten, school, camp, sanatorium). This is required by the rules for the prevention of mass infection of children with parasitic infections.
For the purpose of early detection of helminthic invasions, all patients over 1 year old in a medical institution are advised to conduct a study for helminth eggs at least once a year, regardless of the presence or absence of symptoms of infection.
For the purpose of early detection of helminthic invasions, all patients older than 1 year are advised to conduct a study on helminth eggs at least once a year.
Types of tests for worm eggs
Tests for worms in children are performed using the following methods:
- Stool examination. This type of diagnosis is prescribed to identify ascaris, bovine and pork tapeworm, schistosomes, liver flukes and some other intestinal parasites. Worm eggs are found in feces when examined under a microscope.
- Perianal scraping. For microscopic examination, a material obtained by scraping from the folds of the perianal zone is taken. Thus, pinworm eggs are revealed, which the females lay around the anus of the infected. This method is used only in the diagnosis of enterobiasis, which cannot be detected by examining feces.
- Blood test (ELISA and PCR). In the strict sense of the word, ELISA and PCR are not considered tests for egg-leaf, since they allow to identify not the eggs of parasites, but the very fact of the presence of helminthiasis at any stage of its development. Nevertheless, these methods are considered the most accurate and widely used in the diagnosis of parasitic infections in children. A blood test helps to determine not only common types of helminthic invasions, but also more rare ones.

The study of feces is prescribed in order to identify ascaris, bovine and pork tapeworm, schistosomes, hepatic flukes.
Carrying out an analysis for the eggs of worms in children does not imply a particularly thorough preparation. If a feces or scraping is required for research, the child should not be washed. In addition, it is forbidden to stimulate bowel movements with laxative suppositories and enemas. The bowel movement should take place naturally.
To collect biomaterial, you need to purchase a sterile container with a small plastic spatula or cotton-tipped applicator in the lid.
How to get tested correctly
This is best done in the morning, right after the child wakes up.
To collect feces for research, it is necessary for the child to empty into a pot, which must first be thoroughly washed with laundry soap and rinsed with boiling water. Then you need to take a small amount of material using a special spatula that comes with the purchased sterile container. In this case, you need to touch different sides of the feces, since the eggs of the parasites may be unevenly distributed in the feces.
If a baby needs to be tested, feces are collected from a clean diaper in the same way. The weights taken from the diaper are not suitable for research.

After collecting the material, close the lid of the container and deliver the container to the laboratory within 2 hours. It is recommended to donate feces for eggs of worms 2-3 times in a row with intervals of several days.
Material for analysis for enterobiasis can be handed over at a medical institution or collected independently at home. For this, the child needs to be put on his side with his back to you, spread his buttocks and hold several times around the anus with a prepared cotton applicator, which must then be placed in a container.

The timing of making tests for worm eggs depends on the type of diagnosis:
- analysis of feces for egg-leaf - 1-6 days;
- scraping for enterobiasis - 1 day;
- blood test - 2-9 days.
It should be borne in mind that the result obtained during the study is valid for a limited time. If, after this period, the certificate on the results of the diagnosis was not used for its intended purpose, then the child will have to take the analysis again in order to get fresh information. Most often, results are valid no more than 10 days.
Stool analysis and scraping for enterobiasis is done free of charge in most state clinics, provided that the patient has a doctor's referral. In private medical institutions, these procedures cost about 300-400 rubles.
In private medical institutions, these procedures cost about 300-400 rubles.
The cost of a blood test depends on what type of helminth needs to be identified. So, to conduct a study on Trichinella or Toxocara, you will need to spend about 500 rubles, for the diagnosis of ascariasis - 800-900 rubles.
Normally, in the results of stool analyzes and in scrapings, eggs of worms should not be found. However, the absence of parasitic particles in the biomaterial is not yet evidence that the child is completely healthy. It is possible to declare with confidence that there are no helminths in the baby's body, it is possible only if the results of all tests on the egg leaf, carried out in a row with a slight interruption, are negative.
If no eggs of the causative agents of the disease were found in the results of diagnostics for enterobiasis, this is not evidence of the absence of other types of parasites.
In the study of blood, antibodies of class M and G are detected, which are produced in the child's body in response to infection with one or another type of worm. If IgM antibodies are found in the test results, this is a sign of recent parasite infestation. In this case, the disease proceeds in an acute form. IgG immunoglobulins indicate the development of a chronic form of helminthiasis.
If no antibodies of either class are found in the blood, this means that the child is not infected with this type of worms. However, this result does not exclude the presence of other types of helminthic invasions.
