The analysis of feces on eggs a worm, which is often used for the identification of carriers of helminths to prevent the spread of parasitic infections in the group of contacting people.
Mandatory submission of this analysis is that workers of a public catering and other professions that require a health book, it is also necessary for the admission of children in kindergartens and educational institutions, when applying for a job, hospitalization, transition treatment, you visit the pool.
In addition, the study of feces on the egg-worm, which can be also diagnostic measures for suspected intestinal helminths. The accuracy of the laboratory results, which will largely depend on how correctly was harvested biological material. This article covers all of the issues relating to the delivery of the analysis from the feces on eggs a worm for kids and adults.
Why do we need analysis?
To take the analysis of feces on eggs a worm is not a formal approach. The person who is assigned must understand that the identification of the helminth infections is important especially for themselves. After all, parasites that cause serious damage, some species are able to penetrate into the liver, brain, heart and other organs.
Laboratory testing of the stool still does not reveal the infection, because in a small sample of biological material placed on the analysis of helminth eggs, may not be possible. Parasites will lay eggs is not constant, so the stool unevenly distributed.
In addition, the results can affect non-compliance with 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 analysis, collection and storage of the sample, and to realize that it would be necessary to re-take, if the analysis shows no parasites.
What symptoms may indicate infection with worms?
Is a symptom that is clearly indicative of the presence of worms is the itching and wiggling in your anus, especially noticeable in the evening and at night. This is typical for enterobiasis – infection with pinworms. The invasion of other types of worms does not have such a clear and characteristic clinical picture, the symptoms can be unexpressed, or is a characteristic of many other diseases.
Suspected helminthiasis can cause the following problems:
- Loss of appetite until its complete absence;
- Bloating and intestinal disorders;
- The presence of blood and mucus in the stool;
- Loss of body weight;
- Frequent headaches, sleep disorders;
- The constant feeling of fatigue;
- Pallor of the skin;
- The weakened immune system, causing susceptibility to frequent colds;
- Grinding the teeth in sleep;
- Problems with the skin.
With the onset of at least some of these symptoms, it should be considered, including the identification of parasitic infections.
How to prepare for the analysis?
To increase the reliability of the result of the analysis of feces on the egg-worm, is a mandatory submission to follow some rules.
There is no sense to explore the mud on the eggs of helminths in the following cases:
- Taking anti-parasitic drugs and immediately after their course;
- After radiographic examination using barium preparations;
- 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 effectiveness of the research can be on some strong drugs. If are not essential, their admission should be discontinued 3 days prior to collection of sample of feces.
If the patient is in the process of healing that cannot be interrupted, for example, a course of antibiotics, delivery of the analysis of feces on eggs a worm it is better to be delayed until the end, because in the changed environment in the gut, the reproduction of the worms is slowing down, and their eggs may not be detected.
It has an effect on the results of the research and the composition of the 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 enters the digestive tract, and the probability content in the feces from the parasite eggs are reduced. So 1-2 days before the collection of stool for analysis on helminth eggs it is recommended to eliminate from the diet foods that cause you to lose the intestines.
For each person, the collection of these products individually, but in General, these include:
- Cabbage and sauerkraut;
- Fresh beet;
- Apricots, plums;
- Prunes;
- Grapes;
- Persimmon;
- Yogurt;
- Cucumbers, zucchini, pumpkins;
- Beans;
- Watermelon, melon.
Also not recommended is the use of the products, coloring the mud in unusual colours – the already mentioned beet, blueberries, cherries, black currants.
Following these simple rules, you can significantly increase the likelihood of identification of the helminth infections and timely initiation of treatment.
What are the rules of collection of stool for analysis?
If you have followed all the rules of preparation for the study of feces for the presence of parasite eggs indicated above, it is possible to prepare a sample material for analysis. Usually this point raises a lot of questions: how much mud for the analysis of the egg-worm, what are the rules of its collection, it is possible to store the material collected, etc., let us consider in more detail the answers to these questions.
The laboratory does not accept for the analysis of 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 to collect the sample and a close fitting lid, do not place the smell.
Sterilize a glass container, especially in the pharmacy, there is no need. The jar and lid is enough to clean baking soda and thoroughly rinse with clean warm water and a container to collect the sludge in the washer is not necessary.
If the collection takes place in the home containers, making it convenient for one-time use of spoon. You can also use a cotton cloth, more matches. For use for this purpose, chips, chips and not sticks, as they may be eggs of parasites, which will lead to distortion of the results of the analysis.
I have to wash?
If the collection of urine must be washed away to avoid getting the biological material from the secretions and microflora that live on the genitals, in the collection of stool for analysis on helminth eggs by washing is not recommended.
Some types of helminths (pinworms) lay eggs around the anus, in the anus can other helminth eggs from the previous tomb.
While passing the stool, which may be in the first part of the biological material, which increases the likelihood of identification of the helminth infections.
How to collect feces for analysis?
This is necessary to defecate in a clean dry pot or container. It is not allowed to "catch" the material out of the water in the toilet. It is also necessary to monitor the mud did not hit the urine to empty the bladder should in another place.
The fence material is produced in several places of the faeces: from the initial segment, in the middle and at the end, with the surface and the depth. Stool sample for analysis, which should be approximately the same size of a walnut.
Immediately after collection, the containers must be tightly closed, the material does not dry out.
How to cause a bowel movement?
Physiological processes do not always lend themselves, mind control, to force the bowel to waste products on demand is almost impossible. The easiest way to collect feces for analysis on helminth eggs, that those people who are used to empty the bowel in the morning, when waking up, because the lab usually accept biological material for the investigation in the morning.
To promote the bowel to empty is not recommended to use enemas, butt plugs, because it reduces the likelihood of obtaining a reliable result of the analysis on the egg-worm, which is not too high.
Morning defecation in a natural way by following these recommendations:
- After waking up drink a glass of cold water;
- After 15-20 minutes, have Breakfast;
- If in 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 down on your back. Relaxing the stomach, perform stroking around the navel in a spiral, the direction of movement – clockwise. The easiest way is, fingers clenched into a fist.
After the massage, do the following exercises to stimulate the bowel, if you want to:
- Standing on all four, draw and relax the stomach;
- Lying on your back, pull your knees up to the chin and then returns to the start position.
If all the above measures had no effect, this means that the analysis will need to collect in advance.
However, before you move on to the next paragraph of this article, and find out how much you can keep of stool for the worm eggs, not to forget, above recommended, improves intestinal motility. Use every day, you will quickly train your body for regular morning bowel movement, which no doubt will be very useful for your health.
How long can you store the material?
Storage of sample 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 from 6 to 10°C. At this storage, the stool is not dry, the eggs, the worms, if present in the sample, types of changes, and will be available for identification. The storage time should not exceed 8-12 hours.
How is the study of the material in the laboratory?
For determining presence of eggs of worms in the feces, as well as their type, the following methods of laboratory research:
- Defend. In this method, the substances to be mixed with water, settled and decanted liquids, oils. This a couple of times. The eggs and fragments of helminths have a higher specific weight therefore they always remain in the sediment. After repeated washing of the colored material can be seen under a microscope for the presence of parasites.
- In elutriation. This method is used for the detection of fragments of the worms. From the 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 microscope. Thus, it is possible to identify fragments of worms and define them.
- Smear the mother. 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 the small amount deposited in the material, that you can simply not get into the fall population, resulting in a negative result of the analysis may be wrong.
- 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. One hour later, the sample acquires the necessary degree of transparency and examined under a microscope. This method is considered to be the most advanced, accuracy is about 85%.
Perform analysis of sludge in egg-worm all of these methods is time-consuming, the result can be ready within a few days of delivery. Delays are typically associated with overload of the laboratories.
What could decrypt the result of the analysis?
Research on 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. For the detection of 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 ensure the absence of parasitic infection.
If, after placing 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 to treatment.
In addition to helminthic infection, with stool sample can be diagnosed infections protozoan infections: Giardia lamblia, dysenteric amoebas, cyclosporine.
What to do when you detect a bot?
If the analysis of the mud on the egg-worm showed the presence in the body of each parasite, then, in any case can not refuse treatment. In addition to the fact that the bot can become an obstacle to the achievement of the objective – admission to work or school, place the child in a kindergarten, preparation of health books, etc, this can cause serious health damage.
Human parasites feed on its vital juices, the selected energy. In addition, reduce the immunity, which can lead to the development of more serious diseases.
It is also unacceptable, and themselves. Antiparasitic products are of high toxicity. Although the form of the parasite is known, the dose of the medicinal product effective against him, he should be running only the doctor, with all the physique and condition of the patient. Treatment should be under the supervision of a specialist, otherwise you may need to serious complications caused by the toxic effects of Anthelmintics.
You should also remember that the eggs from the worms can be transmitted through household items and personal contacts. Therefore, at the detection of parasitic infections in humans of the medical examination and, if necessary, treatment for 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 the indication of the pool, and at the time of the inspection.
