The analysis of a feces on eggs a worm are often administered to identify the carriers of helminths to prevent the spread of the infestation parasitic in the groups contact with the people.
Mandatory the presentation of this analysis to workers of a public catering and other professions that require a health book, it is also necessary for the admission of children to kindergartens and educational institutions, in the case of applying for a job, hospitalization, the step of treatment, you visit the swimming pool.
In addition, the study of the stool of 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 the delivery of the analysis of a feces on eggs a worm for kids 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 assigned must understand that the identification of helminth infestation it is important, in the first place, by himself. After all, parasites cause serious damage, some species are able to penetrate in the liver, brain, heart and other organs.
Laboratory testing of the feces does 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 that the stool unevenly distributed.
In addition, the results may be affected by the breach 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 need 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 late afternoon and evening. It is typical for enterobiasis – infestation of pinworms. Invasion of other types of worms are not so clear and characteristic, the clinical picture, the symptoms can be unexpressed, or is a feature of many other diseases.
Suspected helminthiasis can cause the following symptoms:
- Loss of appetite until its complete absence;
- Flatulence and intestinal disorders;
- The presence of blood and mucus in the feces;
- Loss of body weight;
- Frequent headaches, sleep disorders;
- A constant feeling of fatigue;
- Pal.lidesa of the skin;
- The weakness of the immune system, leading to susceptibility to frequent colds;
- The grinding of teeth in sleep;
- Problems of the skin.
With the appearance of at least some of these symptoms should be treated, including the identification of the infestation parasitic.
How to prepare for the analysis?
To improve the reliability of the result of the analysis of excrement on the eggs of the worm, is required prior to the presentation to follow certain rules.
It does not make sense to have a feces on eggs of helminths in the following cases:
- At the time of taking anti-parasite 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 performance of the research, it can take some powerful drugs. If they are not vital, their admission should be discontinued 3 days before the collection of stool sample.
If the patient is in treatment, which can not be interrupted, for example, a course of antibiotics, the delivery of the analysis of a feces on eggs a worm it is better to postpone until the end because in the changes of the environment in the intestine of 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 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 move the intestinal tract, and the probability content in the excrement of parasites of eggs is reduced. So 1-2 days before the 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;
- Cool the beet;
- Apricots, plums;
- Prunes;
- Grapes;
- Khaki;
- Yogurt;
- Cucumbers, zucchini, pumpkin;
- Bean;
- The watermelon, the melon.
Also not recommended the use of the products, coloring the feces in unusual colors – the aforementioned beets, raspberries, cherries, black currants.
Adherence to these simple rules, you can significantly increase the probability of identifying helminth infection and timely from the start of treatment.
What are the rules for the collection of feces for the analysis?
If you have followed 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. Normally, this point raises many questions: what amount of feces for the analysis of the egg-worm, what are the rules of its collection, it is possible to store the material collected, etc. we are going to Consider in more detail the answers to these questions.
The laboratory cannot accept for analysis of a stool for party 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 stool. This container is convenient because it is equipped with a shovel for collecting the sample and tightly fitting the lid, not the smell.
Sterilize a glass container, especially the pharmacy, there is no need. The jar and lid is enough to clean up the baking soda and thoroughly rinse with clean water and hot water, and a container for the collection of feces in the wash, it is not necessary.
If the collection is done in the home containers, so it is convenient single-use spoon. You can also use a cotton swab, several matches. To serve 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 need to wash?
If the collection of the urine must be washed away, to avoid that in the biological material of the secretions and microflora that live in the genitals, when collecting feces for analysis on helminth eggs to wash it is not recommended.
Some species of helminths (pinworms) lay eggs around the anus, also in the anus, could reduce helminth eggs from the previous to the defecation.
While passing stool, which may be in the first part of the biological material, which increases the probability of identifying a helminth infection.
How to collect feces for analysis?
It is necessary to defecate in a clean and dry pot or container. Can not "catch" the material of the water from the shower. It is also necessary to control stool it were not for the urine to empty the bladder need in another place.
The fence of material produced from various places of the stool: from the segment initial, middle, and end, with the surface and the depth. A stool sample for the 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.
As to cause a bowel movement?
Physiological processes do not always lend themselves to mind control, by the force of the bowel to give the waste products in the demand is nearly impossible. The easiest way to collect feces for analysis on helminth eggs for those people who are used to empty the bowel in the morning after waking up, because the lab usually accept biological material for testing in the morning.
To stimulate the bowel to empty is not recommended the use of enemas, butt plugs, because it reduces the probability of obtaining a result that is reliable for the analysis of the egg-worm, which is not too high.
In the morning the defecation in a natural way, by following these recommendations:
- After waking up drink a glass of fresh water;
- After 15-20 minutes, Breakfast;
- If within 20 minutes after the Breakfast that I wanted to use the shower, do a gentle massage in the abdomen and exercises to strengthen the intestinal peristalsis.
Self-massage of the abdomen is performed lying on the back. Relaxing the stomach, make strokes around the navel in a spiral, the direction of movement of the needles of the clock. It is easier, fingers clenched in a fist.
After the massage, do the following exercises to stimulate the bowel to empty:
- Foot four, 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, this means that the analysis must be collected in advance.
But before we move on to the next paragraph of this article, and find out how much you can store the feces for worm eggs, remember the previous recommended method of improving intestinal motility. Apply it on a daily basis, 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 a sample of material for analysis on helminth eggs is necessary in a closed container tightly, tied in a plastic bag in the refrigerator at a temperature of 6-10°C. In this storage, the stool is not dry, the eggs of worms, if present in the sample, of the 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 laboratory?
To determine the presence of eggs of worms in the feces, as well as the type, the following methods of laboratory research:
- Defense. In this method, the material is mixed with water, settled and decanted the liquid fraction. Do that a couple of times. Eggs and fragments of helminths have a greater specific weight, therefore, must always remain in the sediment. After repeated washing of the precipitated material can be seen under a microscope for the presence of parasites.
- In elutriation. This method is used to detect fragments of worms. Always analysis of the sample semi-liquid mass, and is placed in a Petri dish and tweezers for the removal of particles of light, to examine them under a magnifying glass or microscope. Thus, one can identify fragments of worms and define them.
- Native smear. In this method, under a microscope studied only a drop of the emulsion obtained by dilution of faeces with water. This allows us to detect helminth eggs and protozoan parasites. But with their small amount deposited in the material, that can simply not get to the population from falling, giving rise to a negative result of the analysis may be false.
- A thickness of smear. This method is more informative because it allows us to explore a large amount of material than other methods. The sample size of a pea, is put on a glass slide and pressed against the polymer transparent plate is submerged in the liquid. An hour later, the sample acquires the necessary degree of transparency and examine with a microscope. This method is considered the most progressive, its accuracy is about 85%.
Realization of analysis of 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?
The 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 material deposited is not detected, the result of the analysis in the decoding will be negative. However, a negative result does not guarantee the absence of infestation parasitic.
If after you put the stool of the egg-worm file contains a positive result against any type of worms (or more), its 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 the feces of the egg-worm showed the presence in the body of any parasite, then, in any case, you can't reject the treatment. In addition to the fact that the bot can become an obstacle to achieving the goal – admission to work or school, place the child in the children's education, obtaining health books, etc., can cause serious health damage.
Human parasites feed on its vital juices, the selected energy. In addition, it reduces the immunity, which can lead to the development of more serious diseases.
It is also unacceptable and self-assessment. Antiparasitic products are of high toxicity. Even if the form of the parasite is known, the dose of a drug that is effective against him, has to be installed only by a physician, with all the physical and the state of the patient. The treatment must be under the supervision of a specialist, otherwise, can 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, after the detection of an infestation parasitic in humans medical examination and, if necessary, treatment of other members of the family, including Pets.
How often should I get tested?
Normally, the analysis of stool of the egg-worm seems to be a time in the receiving kindergartens and educational institutions, at work, in a hospital, sanatorium, when reference is made to the pool, and at the time of the exam.
