Stool examination for the eggs of the helminth is most often prescribed to identify carriers of helminths to prevent the spread of parasitic infestation in groups of contact with people.
Mandatory surrender of this analysis for the food and beverage services and other occupations that require a sanitary portable, also it is necessary in the admission of children in day-care and educational institutions, employment, hospitalization, the passage of sanatorium treatment, the visit of the swimming pool.
In addition, the study of cala on an egg-a worm of earth can be identified among the diagnostic measures in cases of suspicion of helminthiasis intestinal. The reliability of laboratory results, in large part, depend on how has been correctly assembled to the biological material. This article covers all questions relating to the filing of stool analysis for eggs of helminth children and adults.
Why do you need it?
The rental of the analysis of the stools of the eggs of the helminth was not formally. The man to whom he is assigned, he must understand that the definition of worm infestation is important, first, for himself. In effect, the parasites can cause serious damage on health, some of their species are capable of penetrating the liver, the brain, the heart, and other organs.
Studies in the laboratory of cala is not always identify the infestation, in fact, in the small sample of the biological material to be given to the analysis, the eggs of helminths may not be. The parasites lay eggs is not permanently, this is why in kalovyh weights they are distributed unevenly.
In addition, the results can affect to ignore the rules of training to the analysis, poor collection and storage of material.
It is therefore necessary to strictly observe all the rules of preparation of the exams of analysis, collection, and storage of the sample, and aware of the necessity of re-filing, if the analysis will show the absence of parasites.
What are the symptoms may indicate an infection by worms of the earth?
The symptom indicating the presence of earthworms, itching and a hubbub in the anus, in particular tangible, the evening and the night. It is typical for enterobiasis – infestation of pinworms. The infestation of other types of worms is not so explicit, and the clinical presentation, symptomatology may be expressed, or it refers also to many other diseases.
The suspicion on the helminth infections may cause the following symptoms:
- Decreased appetite until his / her absence;
- Flatulence and intestinal disorders;
- The presence of blood and mucus in kalovyh weights;
- The loss of the mass of the body;
- Frequent headaches, sleep disorders;
- A constant feeling of loss of strength;
- The paleness of the skin;
- The weakening of the immunity, which is expressed in the susceptibility to frequent colds;
- The grinding of teeth during sleep;
- Skin problems.
Upon the occurrence of at least several of these symptoms, you should undergo an examination, including the identification of parasitic infestation.
How to prepare for the analysis?
To increase the degree of confidence the result of the analysis of cala on an egg-a worm of earth, it is necessary before passing its follow certain rules.
There's no sense in exploring the feces on eggs of helminths in the following cases:
- When taking anti-parasitic drugs and immediately after their course;
- After x-ray of the investigation to the application of drugs of barium;
- After the oil enemas.
In all these cases, the probability of detection of eggs of helminths approaches zero, and the results of the analysis may not be meaningful.
Also reduce the effectiveness of the research may receive some potent drugs. If they are not essential, their receipt, you must stop 3 days before the collection of stool for analysis.
If the patient is subjected to a treatment that cannot be interrupted, for example, the course of antibiotics, the currency analysis of the stools of the eggs of the helminth is better to postpone to its end, given that the conditions of the new environment in the intestine of the reproduction of 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 the man ate the day before the collection of biological material. When the consumption of products contributing to the increase of the gas and looser bowel, the masses are fast tract, and the probability content in the feces of eggs down. Therefore, for 1-2 days before the collection of stool for analysis on eggs of helminths, it is recommended to exclude products that cause a loosening of the bowels.
For each person, all of these products is different, but in general, these include:
- Fresh and sauerkraut;
- Costs of the beet;
- Apricots, plums;
- Prunes;
- Grapes;
- Persimmons;
- The kefir;
- Cucumbers, zucchini, pumpkin;
- Pulses;
- The watermelon, the melon.
It is not recommended to consume foods, cal-unusual color – already mentioned, beets, blueberries, cherries, and cassis.
By respecting these simple rules, you can greatly improve the chances to identify the worm invasion in a timely manner and begin treatment.
What are the rules for the collection of stool for testing?
If respect all the rules of the research training fecal masses on the eggs of the parasites listed above, then you can produce the collection of a sample of material for analysis. Usual this time, raises a lot of questions: how much of the stool for analysis of the egg-worm, what are the rules for the collection, is it possible to store the material collected, etc, will review in detail the answers to these questions.
The laboratory does not take on a stool in the boxes of matches and other in boxes, for the collection of material, you can take a small glass container with a tight fitting lid to buy from the pharmacy or a container made of special plastic for the collection of faeces. This container is very convenient because it is equipped with a scoop for the collection of the sample and a sealed lid, a barrier to the smell.
Sterilize the glass containers, and more – pharmacy, it is not necessary. A small pot and cover just to clean up the baking soda and clean, plenty of hot water and container for collection of stool in the washing does not need.
If the data is collected in a container, then make it the most convenient for disposable spoon. You can also use a cotton swab, several matches. This is supported with the street of cuttings and branches you can't, because they may be eggs of parasites, which will lead to distort the results of the analysis.
If you need to wash?
If during the collection of urine for analysis, you need to wash in order to avoid penetration into the biological material of the secretion and of the microflora present on the genitals, during the collection of stool for analysis of eggs of the helminth wash is not recommended.
Some types of worms (pinworms), lay eggs around the anus, also in the anus can stay with the eggs of helminths of the previous defecation.
When passing fecal mass, they can be in the first portion of the biological material, which increases the probability of detecting a worm infestation.
How to collect feces for analysis?
A bowel movement, you need to clean and dry a pot or a vessel. No pets "flush out" the material of the water from the bowl. You must also make sure, feces has not obtained from the urine, emptying the bladder need in another place.
The fence is made from several locations of the feces: from parting, middle, and end, with the surface and the depth. A stool sample for analysis should be approximately equal to the value of a walnut.
Immediately after the harvest of the tare must close, so that the material does not dry.
As you can call the defecation?
The physiological processes cannot always be in control of the consciousness, forcing the intestines to deliver products of subsistence, on request, it is almost impossible. Easier to collect feces for analysis on eggs of helminths to those who have the habit of emptying the intestines, in the morning after waking up, because the lab usually take biologic materials on the analyses of the morning.
For the stimulation of bowel evacuation is not recommended to apply an enema anal candles, because this reduces the probability of obtaining a reliable result of the analysis of the egg-a worm of earth, which is not too high.
Get up in the morning the defecation of course, you can, according to the following recommendations:
- After waking up, drink a glass of cool water;
- After 15-20 minutes, take your breakfast;
- If, within a period of 20 minutes after the breakfast, you do not want to the toilet, made of the reserves of the self-massage of the abdomen and exercises to strengthen the peristalsis of the intestine.
Self-massage of the belly is lying on the back. Release the belly, produce stroking around the navel, spiral, the direction of rotation in the clockwise direction. The most convenient is to do it by tightening the fingers into a fist.
After the massage, do the following exercises for the stimulation of bowel evacuation:
- Standing on its four legs, draw and relax the stomach;
- Lie on your back, pull your knees up towards the chin, and then return to the starting position.
If all of these measures have had no effect, this means that the material for the analysis will need to collect in advance.
But before moving on to the next step of this article, and see how much you can store the calories from the eggs of the helminth, note recommended by the above method improvement of peristalsis of the intestine. By applying it daily, you will quickly get your body accustomed to the regular emptying of the bowel, and no doubt will be very helpful for your health.
How much can you store the collected material?
Retain the sample of material for analysis of the eggs of the helminth, you must be in a tightly closed container, tied in a plastic bag in the refrigerator at a temperature of +6°to 10 ° C. at such storage cal is not dry, the eggs of helminths, if they are present in the sample, do vido-will change and will be available for identification. The storage time should not exceed 8 to 12 hours.
How is the research equipment in the laboratory?
To determine the presence of eggs of helminthes in the stool, as well as their type, the methods of the laboratory:
- The criminalization. With this method, a material mixed with water, defend, and merging liquid faction. So do several times. The eggs and fragments to have a higher proportion, so that they always remain in the sediment. After several washing of the material is precipitate, visible under the microscope for the presence of parasites.
- In elutriation. This method should be applied to identify the fragments of worms. From the condition on the analysis of a sample produce a semi-fluid mass, put it in a Petri dish and, by pulling with tweezers the light particles, inspect them with the magnifying glass or the microscope. Thus, able to identify fragments of worms and determine their type.
- A native of defilement. With this method, under the microscope, exploring a drop of the emulsions obtained by the breeding of cala water. This enables the detection of eggs of helminths and protozoan parasites. But their small number in the given material, they can simply not enter in the a drop, in consequence of which the negative result of the analysis may prove to be a fake.
- Thick brush stroke. This method is the most informative, because it allows to study a larger number of materials, compared to other methods. A sample of the size of a small pea is placed on a glass slide, and snuggled transparent polymer plate, dipped in the liquid. After one hour, the sample gains the necessary degree of transparency and examined under a microscope. This method is considered the most progressive, its validity is approximately 85%.
Execution of the analysis of the cala on the egg-worm of one of these method doesn't take a lot of time, the result can be ready within days of delivery. Delays are usually due to congestion in the laboratories.
What can be the decryption of the result of the analysis?
Stool examination for eggs of helminthes can only show the presence or absence of parasites that multiply in the gastrointestinal tract: round and tapeworms, liver flukes. For the detection of other helminths, for example, echinococcosis, apply enzyme-linked immunosorbent assay from blood (ELISA).
If the eggs and the fragments of earthworms in given the hardware is not detected, then the result of the analysis in the transcription will be negative. However, a negative result does not guarantee the absence of parasitic infestation.
If, after the filing of the analysis of a stool of the egg-worm decryption returns a positive result in respect of any species of worms (or more), their existence certainly does not patient and the treatment is prescribed.
In addition to worm infestation, with the help of the analysis of the stool may be diagnosed with a protozoal infection of micro-organisms: Giardia, dysenteric amoebas, cyclosporine.
What to do in case of helminth infection?
If analysis of the cala on the egg-worm revealed the presence in the body of any parasite, in any case, you can not abandon the treatment. In addition to the fact that helminth infections, can become an obstacle to achieve the goal of admission to work or to school, the device of the child in the kindergarten, more sanitary, portable, etc, it can cause serious damage to the health.
The parasites of man, feed on his life of juice, a quebec energy. In addition, because of their decreased immunity, which can lead to even more serious diseases.
Not also and self-medication. Anti-funds are of great toxicity. Even if the type of parasite is known, the dosage of a drug effective against him, shall be installed only by a physician, taking into account all the physical data and the state of the patient. The treatment must be under the control of a specialist, otherwise, there may be serious complications related to a toxic effect of deworming.
Also it must not be forgotten that the eggs of helminths are transmitted easily through the objects of everyday life, and by personal contacts. Therefore, during the detection of parasitic infestation in humans, an investigation and, where appropriate, the treatment of the other members of his family, including the pets.
As often, you need to do the test?
Usually, the analysis of cala on an egg-a worm of earth is distributed once when the admission in nursery schools and educational institutions, at work, in a hospital, sanatorium, during the presentation of the assistance to access the pool, as well as during the passage of the clinical examination.
