Roundworms are a fairly large species of roundworms. They are capable of affecting many internal organs, causing various kinds of complications. A complex of different methods is used to treat ascariasis.

Before prescribing drugs, the patient needs to be tested for roundworms: blood and feces. The results obtained allow the specialist to choose the most effective means to combat ascaris.

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 an analysis for roundworms, and what are the types

Tests for the detection of helminthic invasion should be taken not only at the stage of exacerbation of symptoms, but for preventive purposes. Diagnostics allows you to determine the presence of a parasite in the body at an early stage, which allows the doctor to choose adequate methods of therapy.

Before the appointment of tests, the patient is interviewed, the doctor examines the clinical manifestations. Without a personal examination and communication with the patient, the doctor cannot diagnose ascariasis.

If the clinical manifestations are similar to ascaris invasion, the patient is prescribed the following tests:

  • general clinical - feces for the presence of a parasite. Also, you can not do without a general study of the patient's blood. The presence of anemia or an increased content of eosinophils is a sign of invasion. Biochemical examination of urine allows you to identify the waste products of the parasite;
  • specific examination of feces, sputum;
  • laboratory methods - allow you to identify antibodies that the body produces to fight ascaris;
  • if necessary, the patient is prescribed ultrasound, CT, MRI, X-ray, endoscopy.

The research method can be determined by the stage of development of the pathology:

  • specific and serological methods are effective at the migration stage. They can be accompanied by ultrasound, endoscopy, CT;
  • at the intestinal stage, coproscopy and blood tests are informative. Ultrasound, CT are used to confirm the results.

At the initial stage, a complete blood count may show an increased number of eosinophils.

Larvae can be found in sputum. You can see eggs in feces only 2 months after infection.

The most effective method for early diagnosis of ascariasis is ELISA, which allows you to determine the presence of antibodies to the parasite.

Usually it is prescribed:

  • patients with prolonged cough that does not respond to treatment, anemia, upset stools, recurrent allergies;
  • a family in which someone is being treated for ascariasis;
  • a person who has undergone treatment - allows you to determine the effectiveness of therapy.
How to take Decoding
The patient does not need to undergo special training. Blood is taken from a vein on an empty stomach. The blood is mixed with ascaris antigens - the indicators are evaluated based on the results of mixing. ELISA detects antibodies of Ig class M and G, indicating the stage and presence of invasion.

M indicates the acute stage of infection - the first two weeks of invasion. G - a sign of prolonged invasion, the patient may have previously been treated for ascariasis. This marker after therapy is reduced by half, after six months it completely disappears.

  • It is considered normal if antibodies are not detected, which means that there was no parasitic infection. It is considered negative when the titer is less than 1/1, the CP is positive when it is less than 1.1.
  • Antibodies are detected - a sign of a previous infection or its presence. Tests with a titer of 1/600 or more are considered positive, KP is more than 4.2.
  • Doubtful results if the titer is 1 / 200-1 / 400, KP 1.2-4.1. Re-examination of biological material is required.

Stool tests for roundworm

This study is the most common among the prescribed tests for detecting helminthic invasion.

Conventional methods (coproovoscopy, coprogram) show high results only in the presence of worm eggs in the intestines. This requires a chronic course of the invasion.

The presence of too old, immature, same-sex worms, the tests will not be able to reveal To clarify the preliminary diagnosis, it is necessary to carry out the PCS - it allows you to determine the traces of the vital activity of the parasite and particles of their DNA.

How to take Decoding
Before delivery, you must exclude the use of any medications at least 5 days before the tests. The biomaterial is collected with a spatula and placed in a sterile container (you can buy it at any pharmacy).

It is important to exclude the mixing of feces with water, urine. Do not stimulate bowel movements with laxatives or enemas.

Compliance with the rules and the characteristics of the course of infection affect the reliability of the results. The acute stage is the most informative, the error is no more than 10%. If IgG antibodies are found in the biomaterial, it is a sign of infection.

After the first delivery of the analysis, a second diagnosis is carried out. The doctor will prescribe when it needs to be done. This allows you to determine the progress in treatment or the invasion continues to develop dynamically.

Tests for roundworm in children

Infection of young children occurs quite often. If the parents have any suspicions, you should consult a doctor. For a baby, the test procedure will be completely identical to that of an adult.

There are no specific differences. In most cases, the symptoms of infection are more intense - this is due to the peculiarities of the work of the body's defenses.

With positive and weakly positive indicators, it is taken into account that immunity produces antibodies to parasites of this species for a certain period of time. Therefore, the patient will have to re-undergo the examination after a while. Re-delivery will allow you to find out a reliable result and choose a therapy method.

Ascariasis occurs in both adults and children. If negative symptoms appear, you urgently need to contact a medical institution for tests.

You can not resort to self-medication methods without knowing the exact cause of the disease - this negatively affects the patient's condition, can cause irreparable consequences and significantly complicate further treatment with recovery.
