Worm infestation (helminthiasis) is a common problem in children. In order to timely identify this pathology, periodic examination cannot be ignored.

The most accurate method for detecting helminths is the donation of blood for analysis.

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 >>>

When is the analysis necessary?

It is recommended to take the analysis for worms regularly, even though there are no symptoms.

Although, there are typical signs that indicate the presence of worms in a child:

  • Cough and rash of an allergic nature. By the way, a cough is not associated with a respiratory illness. These symptoms are a response to the waste products of parasites.
  • At night, itching appears in the anus.
  • Fatigue and weakness. This can be explained by the fact that the child's body poorly assimilates useful incoming substances.
  • A sharp decrease in body weight. Oddly enough, but when you eat a sufficient amount of food, the weight becomes less and less. The explanation is simple: all the nutrients entering the body are eaten by helminths.
  • Headache and dizziness. This is due to the intoxication of the body.
  • The work of the digestive tract is disrupted. There is nausea, vomiting, and abdominal pain. Such symptoms clearly indicate the presence of parasites in the intestines.

What are the types of tests for worms?

To detect worms in the body, a number of specific studies are carried out.

Immunoassay blood test

For this analysis, blood is taken from a vein, which is checked for the presence of antigens and antibodies to parasites. Antibodies are proteins called immunoglobulins, which are produced in the body, reacting to the vital substances of helminths, which are antigens.

The advantage of this study is that it can detect infestation at an early stage. The accuracy of the analysis reaches 95%.

What the analysis shows:

  • Type of parasite;
  • How it reproduces;
  • The number of helminths in the body.

The analysis is deciphered by counting the number of antibodies JgG, JgM, JgA.

The stage of invasion is determined by analyzing the results:

  • When 3 antibodies are absent in the body, the result is considered negative. This means that the child has a stable immunity to worms.
  • When immunoglobulin G is positive (JgG (+)), it means that the child recently had this infection.
  • Indicators JgM (-), JgG (- / +), JgA (+/-) indicate a chronic form of pathology in a child.
  • The result indicates the acute phase of the disease - JgM (+), JgG (- / +), JgA (- / +).
  • The result of JgM (+), JgG (+), JgA (+) indicates that this infection has worsened.
  • With a negative indicator of immunoglobulin M, we can talk about an absolute recovery of the child.

If we compare this analysis with other laboratory methods, then the enzyme immunoassay has a large number of advantages: high accuracy, determination of the stage of the disease.

What methods are used to detect helminth infection?

The main diagnosis of blood for worms is called ELISA (enzyme-linked immunosorbent assay). It detects specific antibodies to parasites. The accuracy and specificity of this method is quite high. It may not be effective for intestinal helminthiasis without a migratory stage.

The diagnostic method is based on the introduction of special reagents into the patient's blood sample, which react with antibodies to parasites, forming enzyme complexes.

To identify these complexes, additional reagents, special conditions are used, or the resulting compounds themselves give a noticeable precipitate. If there is any noticeable change in the sample, the result is considered positive.

If the type of parasite is not exactly known, then ELISA is performed for several types of parasites at once. The result may be negative - all the species for which the analysis was carried out are absent, positive (the type of helminth is indicated). A related result means that it is impossible to give an unambiguous answer, therefore, it is necessary to retest the blood.

If you suspect helminths, in the development cycle of which there is a migration stage, a serological test may be prescribed to detect helminth antigens in the blood. It is carried out in a similar way to ELISA, only its purpose is directly helminth antigens.

The most rare method for detecting helminthiasis is microscopic. In extremely rare cases, it can detect the presence of a pathogen, for example, ascaris larvae. This technique is practically not used to detect intestinal helminthiasis, since its accuracy is extremely low.

How do children take a feces test for oviduct?

So, how to get tested for helminth eggs? In order for a laboratory study to show the correct result, you must adhere to certain rules for the delivery of feces:

  1. Biological material should be obtained as a result of spontaneous bowel movement;
  2. It is necessary to make sure that no urine and other foreign impurities get into the sample under study.

It is desirable that the process of emptying the intestines be on the same day when the patient will donate biological material. Ideally, they donate feces within 2-3 hours after bowel movement. The maximum storage time is 24 hours. Store in the refrigerator in the door on the bottom shelf.

Preparation for a test for helminthiasis

To correctly pass the analysis for worms, parents must take care. The study of feces is an informative method, however, errors in the preparation process can significantly distort the results.

The preparation rules are as follows:

  • Seven days before the collection of biological material, castor oil and other laxatives should not be given to the child. You can not take antiparasitic drugs, antibiotics, antidiarrheal drugs. If the baby has problems with stool, then the doctor can help with this - he prescribes a drug that will facilitate the natural act of defecation, while not affecting the final result of laboratory diagnostics;
  • It is recommended to take care of dishes for stool samples in advance. Matchboxes are in the distant past. Now you can purchase a special container that comes with a spatula for collecting feces.

Due to the specifics of the life cycle of parasitic individuals, the study is carried out several times - at least three times. If the first analysis showed a negative result, this does not mean the absence of helminths in the child's body. The coprogram should be performed three times with an interval of five days. When three forms are written negatively, they may additionally recommend donating blood.

A few days before the coprogram, it is recommended to exclude from the diet food products that provoke increased gas production, loose stools, bloating in the abdomen, heartburn, and other unpleasant symptoms. For example, beets have a laxative effect, and sauerkraut causes gas production.

Blood test for worms

Many parasitic diseases are disguised as pathological conditions not associated with helminthiases. Therefore, in order to make the correct diagnosis, it is recommended to donate blood for worms. There are studies for each type of helminth. However, it is not always possible to establish the cause of the malaise, therefore, universal research options are used.

A blood test can be performed by the following methods:

  1. Enzyme-linked immunosorbent assay (ELISA);
  2. PCR (polymerase chain reaction);
  3. Immunofluorescence method;
  4. Hemoscanning;
  5. RNGA.

The doctor decides which analysis to choose on an individual basis. However, in most pictures, an enzyme immunoassay is taken as a basis, and the rest of the tests are an additional option. ELISA is used not only for making a diagnosis, but also during treatment - it helps to determine the dynamics of helminthic invasion.

The method of immunofluorescence is a method due to the use of special coloring components. It is used to detect antibodies and antigens. Conducted only in private clinics, the study involves two stages.

One drop of biological fluid is enough to carry out hemoscanning in a child. The analysis reveals:

  • The state of the immune system;
  • Leukocyte count;
  • Plasma viscosity;
  • The concentration of erythrocytes.

The blood is examined under multiple magnification. But it does not show a living parasite or its eggs. Altered blood fluid cells tell about helminthiasis. The experience of a doctor is of great importance for the accuracy of diagnosis.

Additional diagnostics identifying parasites

In addition to the above tests for worms in children, there are other equally effective studies. Such tests are not specific and are usually prescribed during a comprehensive examination.

  • Coprogram is an analysis of feces that allows you to identify parasites and assess the functionality of the digestive system. The biomaterial for the test is feces; in time, the coprogram is made from 1 to 3 days. An analysis is prescribed for suspected amebiasis and helminthic invasion.
  • Hemoscanning of blood for parasites - analysis of leukocytes under a microscope, which allows detecting disorders in the body The presence of parasites is indicated by a large number of eosinophils. The test is done for 1.5-2 hours, blood is taken from a finger. This method has a significant drawback - a very high cost.
  • Bioresonance scanning is a non-invasive method that tests electromagnetic oscillations emitted by the cells of the body. Conventional medicine considers this study to be quackery.

Prevention

The main task of parents is the timely detection of the problem. The results of tests for worms in children show the presence or absence of parasites. But you can avoid infection with worms by applying preventive measures.

  • Follow simple rules of hygiene (hand washing).
  • Wash toys made of fabric, wash the rest thoroughly.
  • Wash vegetables and fruits under running water.
  • Heat the meat and fish.
  • Give pets for worms regularly.

Conclusion

Children need protection and attention. How parents monitor their child's health will determine his future health. The defeat of the body by helminths is one of the most common causes of poor health in children. To prevent a slight malaise from developing into a serious illness, it is necessary to regularly take tests for worms in a child.
