How correctly to pass the analysis of a feces on eggs a worm

Very often a certificate of absence of helminthic invasions is required. Therefore, many people have the question: "The analysis of feces on eggs worm, how to take?". Investigations of feces on eggs worm allows to identify helminthiases in the body of adults and children.

The analysis allows to find out:

• flukes;
• lentets.

General rules for the delivery of stool

To make the results of the tests more reliable, you need to know how to properly pass the feces for the study:

1. Biomaterial for analysis should be obtained due to a spontaneous act of defecation, i.e., without the aid of an enema and the use of laxatives.
2. It should be ensured that urine, excretion from the genitals, menstrual blood is not included in the test sample.
3. No analysis is carried out on egg worms in patients with bleeding, suffering from hemorrhoids, anal fissures, gum disease, accompanied by bleeding.

It is desirable that the emptying of the intestine occurred on the day the material was delivered. It is best if the sample is given a maximum within 30-45 minutes after defecation. It is allowed to collect feces the night before or the day before the analysis. In this case, the sample material is stored at a temperature of 4-5 degrees. Do not allow it to freeze.

Important!The longer the biomaterial is stored, the less reliable the results will be.

2 days before the test, it is not necessary to eat foods that increase gas formation and cause liquid stool or constipation, as well as staining feces, for example, beets.

When it is possible to refuse the use of certain pharmaceuticals that change the color of feces (activated charcoal, bismuth and iron preparations), their composition (rectal suppositories) or acting on peristalsis (pilocarpine).

Important!After X-ray diagnosis of the gastrointestinal tract and the delivery of feces for the study should pass a minimum of 2 days.

How to pass to an adult

The analysis can be assigned to both children and adults. At the same time, there is no difference how to collect and hand over the biomaterial. The feces are collected in a clean and dry glass or plastic container. The optimal option is a disposable container with a screw cap and a spatula.

1. It can be purchased at a pharmacy. Cal for research is taken from several places of a single portion (top, sides and inside) in the amount of 1 teaspoon.
2. If feces are collected from the toilet, then it is better to cover with cellophane and collect the material already from polyethylene.
3. On the dishes you need to write the patient's name and initials, his date of birth and the time of collection of the biomaterial.

In pregnancy

Pregnant women are prescribed to give feces for eggs with a worm for a period of 7-11 weeks. At pregnant women often helminths are allocated spontaneously. They also need to be handed over to the laboratory for analysis together with a sample of feces.

How to collect a feces and give an analysis to a child

If the child is 1 year old or less, it is easiest to collect the feces from the diaper. Pediatricians are advised to use a homemade diaper from a diaper.

To wash a baby before the act of defecation is unlikely to happen, since it is not known when a child goes to the toilet, so it will be enough to conduct usual daily hygiene procedures.

What to do if the baby does not have a chair

If the infant does not have a stool, then the anus can be stimulated. To do this, you need vaseline oil and a gas pipe.

Place an oilcloth on the bed, put the baby on her, on her back or on her right side, and her legs should be bent at the knees. Leave the end of the gas pipe with petrolatum oil and put the child in the anus at a maximum of 1 cm. After three minutes the baby goes to the toilet. If this does not happen, massage the tummy to the child clockwise. After 20 minutes, re-insert the gas pipe.

To stimulate the anus, you can use a mercury thermometer. Its tip should be held several times clockwise near the anus. You can grease the tip of the thermometer with vaseline or boiled vegetable oil and insert it into the anus of the baby for 1 cm. It is better to use a conventional mercury thermometer, since there is usually no effect from the electronic thermometer.

When a child is older and goes to the toilet, the feces are collected from the pot. In this case, urine should not enter the biomaterial under study.

Important!When collecting stool from the pot, it must be washed with baby soap and rinsed thoroughly. Do not wash the pot with disinfectants. You can lay a pot of food film or a plastic bag and already with them to collect feces.

How much analysis is done

How much analysis is being prepared depends on the laboratory, in some days the analysis is 1 day and the result is ready for another day, and in some the results will be known only after 6 working days.

Many do not know where to pass the helminth analysis? You can take the analysis in a local polyclinic, or in an independent medical laboratory, for example, Invitro.

Interpretation of results

Normally, the result should be negative, that is, helminth eggs should not be detected in the test sample. In the case of a positive result, the form of the analysis indicates which species of helminths was found.

When passing the analysis, you need to take into account one point that helminths lay eggs and multiply not every day, but at a certain time. Therefore, it is desirable to take the feces 3 times with an interval of 2 days. Only in the case of a negative triple result can we speak about the absence of helminths in the body.

Types of tests for worms

In addition to putting the feces on egg worm, there are more effective analyzes that allow to detect helminths in the body, for example, scraping for enterobiasis. It allows to detect pinworm eggs in 50% of infected, while the usual analysis of feces reveals helminthiases only in 10-15% of patients.

To obtain reliable results, scrapings should be repeated at intervals of a couple of days. Before passing the analysis, it is not necessary to wash the anorectal area and empty the intestine, then the results will be more accurate.

Biomaterial sampling is carried out in the morning, immediately after awakening. You can do scrapings in a medical institution with the help of medical staff or on your own. To do this, you need either a special container with a cotton swab or a slide with an adhesive tape.

Collection of biomaterial in a container with a cotton swab:

1. Open the container, remove the cotton swab.
2. Spread the buttocks, draw a stick around the anus and place it back in the tube.

Biomaterial sampling on a slide:

1. Remove the adhesive tape from the slide, spread the buttocks, glue the sticky tape on the skin around the anus for 2 seconds.
2. Then again, glue it on the glass in the same place. Make sure that the sticky side does not touch any foreign objects.

To detect helminthic invasions, an enzyme immunoassay is recommended that can detect a disease in 95% of the infected.

In venous blood, immunoglobulins and antigens are detected to the worms. Immunoenzyme analysis allows detecting helminth infections in the initial stages. Depending on the type of worms, the results of the study are ready in 1-7 days.

In acute helminthiasis, you can use other methods:

• endoscopic diagnosis and biopsy;
• computed tomography;
• Ultrasound;
• X-ray of visceral organs;
• latex agglutination reaction;
• the Coombs method;
• reaction of passive hemagglutination.

Each study is assigned individually, depending on the clinical picture of the disease.
