How to collect feces for analysis for parasites?

The analysis of a feces on eggs a worm often administered to identify carriers of helminths to prevent the spread of parasitic infestation in the groups of contacting people.

Mandatory submission of this analysis to workers of a public catering and other professions that require a health book, it's also necessary for admission of children in kindergartens and educational institutions, when applying for a job, hospitalization, the passage of of treatment, you visit the pool.


In addition, the study of feces on the egg-worm can be assigned including diagnostic measures for suspected intestinal helminths. The accuracy of laboratory results will largely depend on how correctly was harvested biological material. This article covers all questions relating to delivery of analyses of a feces on eggs a worm for children and adults.

Why do we need analysis?

To take the analysis of a feces on eggs a worm is not a formal approach. The person he assigned must understand that the identification of helminth infestation it is important, first and foremost, for himself. After all, parasites cause serious harm, some species are able to penetrate into the liver, brain, heart and other organs.

Laboratory testing of stool not always reveal an infestation, because in a small sample of biological material put on the analysis of helminth eggs may not be. Parasites lay eggs is not constant, so the stool unevenly distributed.

In addition, the results may be affected by the disregard of the rules of preparation for the analysis, the incorrect collection and storage of the material.

Therefore, it is necessary to strictly follow all the rules of preparation for the analysis, collection and storage of the sample, and to realize the necessity of re-taking, if the analysis shows the absence of parasites.

What symptoms may indicate infection by worms?

The symptom clearly indicates the presence of worms is the itching and wiggling in the anus, especially noticeable in the evening and night. It is typical for enterobiasis – infestation of pinworms. Invasion of other types of worms does not have such a clear and characteristic clinical picture, symptoms can be unexpressed, or is characteristic of many other diseases.

Suspected helminthiasis can cause the following symptoms:

    Intestinal disorders
  • Loss of appetite until its complete absence;
  • Flatulence and intestinal disorders;
  • The presence of blood and mucus in the stool;
  • Loss of body weight;
  • Frequent headaches, sleep disorders;
  • A constant feeling of fatigue;
  • Pallor of the skin;
  • The weakened immune system causing susceptibility to frequent colds;
  • Grinding of teeth in sleep;
  • Skin problems.

With the appearance of at least a few of these symptoms must be examined, including the identification of parasitic infestation.

How to prepare for the analysis?

To enhance the reliability of the result of the analysis of a feces on the egg-worm, is required before submission to follow certain rules.

Does not make sense to explore a feces on eggs of helminths in the following cases:

  1. When taking anti-parasitic drugs and immediately after their course;
  2. After radiographic examination using barium preparations;
  3. After the oil enema.

In all these cases, the probability of detection of helminth eggs is close to zero, and the results of the analysis may not be revealing.

Also reduce the performance of research may be taking some potent drugs. If they are not vital, their admission should be discontinued 3 days prior to collection of stool sample.

If the patient is undergoing treatment, which cannot be interrupted, for example, a course of antibiotics, the delivery of the analysis of a feces on eggs a worm is better to postpone until the end because in the changed environment in the intestine the reproduction of the worms is slowing down, and their eggs may not be detected.

Has an impact on the results of the research and composition of food that people ate before the collection of biological material. With the use of products that contribute to increased flatulence and loose bowels, the food supply quickly pass the intestinal tract, and the probability content in the feces of parasite eggs is reduced. So 1-2 days before collection of feces for analysis on helminth eggs it is recommended to eliminate from the diet foods that cause loose bowels.

For each person the collection of these products individually, but, in General, these include:

  • Cabbage and sauerkraut;
  • Fresh beets;
  • Apricots, plums;
  • Prunes;
  • Grapes;
  • Persimmon;
  • Yogurt;
  • Cucumbers, zucchini, pumpkin;
  • Bean;
  • Watermelon, melon.

Also not recommended the use of the products, coloring feces in unusual colors – the already mentioned beets, blueberries, cherries, black currants.

Adhering to these simple rules, you can significantly increase the likelihood of identifying helminth infection and timely initiation of treatment.

What are the rules of collecting feces for analysis?

If you followed all the rules of preparation for the study of feces for the presence of parasite eggs indicated above, it is possible to produce a sample of material for analysis. Usually this point raises many questions: how much feces for analysis on the egg-worm, what are the rules of its collection, is it possible to store the material collected, etc. let us Consider in detail the answers to these questions.

The laboratory does not accept for analysis a stool to match and other cardboard boxes, for the collection of material you can take a small glass container with a tight lid or buy in the drugstore special plastic container for collection of faeces. This container is convenient because it is equipped with a shovel for collecting the sample and tightly fitting lid, not passing the smell.

Sterilize a glass container, especially the pharmacy, there is no need. The jar and lid is enough to clean baking soda and thoroughly rinse with clean hot water and a container to collect feces in the wash is not needed.

If collection is done in the home containers, making it convenient disposable spoon. You can also use a cotton swab, several matches. To use for this purpose, chips, chips and not sticks, as they may be eggs of parasites, which will lead to distortion of results of the analysis.

Do I need to wash?

If the collection of urine must be washed away, to avoid getting in the biological material of the secretions and microflora that live on the genitals, when collecting feces for analysis on helminth eggs to wash is not recommended.

Some species of helminths (pinworms) lay eggs around the anus, also in the anus could remain helminth eggs from the previous defecation.

While passing stool, they may be in the first portion of the biological material, which increases the likelihood of identifying a helminth infection.


How to collect feces for analysis?

It is necessary to defecate in a clean dry pot or vessel. Not allowed to "catch" the material from the water of the toilet. It is also necessary to monitor the feces did not hit the urine to empty the bladder need in another place.

The fence material is produced from multiple places of faeces: from the initial segment, middle and end, with surface and depth. A stool sample for analysis should be approximately equal to the size of a walnut.
Immediately after collection, the containers should be tightly closed, the material does not dry out.

How to cause a bowel movement?

Physiological processes do not always lend themselves to mind control, to force the bowel to give the waste products on demand is almost impossible. The easiest way to collect feces for analysis on helminth eggs to those people who used to empty the bowel in the morning after waking up, because the lab usually accept biological material for tests in the morning.

To stimulate the bowel to empty is not recommended to use enemas, butt plugs, because it reduces the probability of obtaining a reliable result of the analysis on the egg-worm, which is not too high.

To morning defecation in a natural way by following these recommendations:

  1. After waking up drink a glass of cool water;
  2. After 15-20 minutes, have Breakfast;
  3. If within 20 minutes after the Breakfast you wanted to use the toilet, make a gentle massage of the abdomen and exercises to strengthen the intestinal peristalsis.

Self-massage of the abdomen is performed lying on the back. Relaxing the stomach, perform stroking around the navel in a spiral, the direction of movement – clockwise. It's easiest, fingers clenched into a fist.

After the massage, do the following exercises to stimulate the bowel to empty:

  • Standing on all fours, draw and relax the stomach;
  • Lying on your back, pull your knees up to your chin and then return to the starting position.

If all the above measures had no effect, it means that the analysis will have to collect in advance.

But before you move on to the next paragraph of this article, and find out how much you can store feces for worm eggs, remember the above recommended method of improving intestinal motility. Applying it daily, you will quickly train your body for regular morning bowel movement, which undoubtedly will be very useful for your health.

How long can you store the material?

Storing a sample of material for analysis on helminth eggs is necessary in a tightly closed container, tied in a plastic bag in the refrigerator at a temperature of 6-10°C. At this storage, the stool is not dry, the eggs of worms, if present in the sample, species-change, and will be available for identification. Storage time should not exceed 8-12 hours.


How is the study of the material in the lab?

To determine the presence of eggs of worms in the feces, as well as their type, the following methods of laboratory research:

  1. Defending. In this method, the material is mixed with water, settled and decanted the liquid fraction. Do that a few times. Eggs and fragments of helminths have a higher specific weight therefore they always remain in the sediment. After repeated washing of the precipitate material can be seen under a microscope for the presence of parasites.
  2. In elutriation. This method is used to detect fragments of worms. From the provided analysis of the sample made semi-fluid mass, and placed it in a Petri dish and tweezers removing light particles, examine them under a magnifying glass or a microscope. Thus, one can identify fragments of worms and define them.
  3. Native smear. In this method, under a microscope studied only one drop of the emulsion obtained by dilution of faeces with water. This allows to detect helminth eggs and protozoan parasites. But with their small amount deposited in the material, they can simply not get into the population drop, resulting in a negative result of the analysis may be false.
  4. A thick smear. This method is more informative because it allows to explore a larger amount of material than other methods. The sample size of a pea is placed on a glass slide and pressed against the transparent polymer plate is dipped in the liquid. An hour later, the sample acquires the necessary degree of transparency and examined under a microscope. This method is considered the most progressive, its accuracy is about 85%.

Performing analysis of a feces on the egg-worm any of these method is time consuming, the result can be ready within days of delivery. Delays typically are associated with overload of the laboratories.

What could be the decryption result of the analysis?

Research of a feces on eggs of worms may show only the presence or absence of parasites that reproduce in the gastrointestinal tract: round and tapeworms, and flukes. To detect other helminths, for example, echinococcosis, used enzyme-linked immunosorbent assay (ELISA).

If the eggs and fragments of worms in the deposited material is not detected, the result of the analysis in decoding will be negative. However, a negative result does not guarantee the absence of parasitic infestation.

If after putting the stool on the egg-worm transcript contains a positive result against any type of worms (or more), their presence is beyond doubt, and the patient is assigned a treatment.

In addition to helminthic infection, with stool sample can be diagnosed by infection of protozoan infections: Giardia lamblia, dysenteric amoebas, cyclosporine.

What to do when detecting bot?

If the analysis of feces on the egg-worm showed the presence in the body of any parasite, then in any case can not refuse treatment. Besides the fact that the bot can become an obstacle to achieve the goal – admission to work or school, place the child in the preschool, obtaining health books, etc., it can cause serious health damage.

Human parasites feed on its vital juices, the selected energy. In addition, they reduced immunity, which can lead to the development of more serious diseases.


It is also unacceptable and self. Antiparasitic products are of high toxicity. Even if the form of the parasite is known, the dosage of the drug effective against him, should be installed only by a physician, with all the physique and condition of the patient. Treatment must be under the supervision of a specialist, otherwise you may have serious complications caused by the toxic effect of Anthelmintics.

You should also not forget that the eggs of the worms are easily transmitted through household items, and personal contacts. Therefore, upon detection of a parasitic infestation in humans medical examination and, if necessary, treatment of other family members, including Pets.

How often should I get tested?

Typically, the analysis of feces on the egg-worm seems to once at receipt in kindergartens and educational institutions, at work, in a hospital, sanatorium, when making reference to the pool, and at the time of examination.
