The analysis of the feces for worm eggs are often prescribed to identify the carriers of helminths, with the aim of preventing the spread of pests infestations in contact groups of people.
It is mandatory for the delivery of this analysis to the employees of the catering and other professions that require health portable, he, too, is necessary for the admission of children in preschool and educational institutions, the work, the hospitalization, the step of thermal processing, access to the swimming pool.
In addition, the study of feces for egg-worm can be assigned, to which diagnostic measures in case of suspicion of helminthiasis intestinal. The reliability of the results of the laboratory test will depend in large part on the way in which it was collected the biological material. In this article are illuminated all questions relating to examinations of the feces for worm eggs children and adults.
Why do you need analysis?
The yield analysis of the feces for worm eggs not to approach formally. The person who has appointed, must understand that the identification of infestations by helminths important, first of all, for him. Because the parasites cause severe damage to health, some types of them are able to penetrate in the liver, brain, heart and other organs.
Laboratory tests cala does not always reveal of the invasion, because in a small sample of biological material, and surrendered to the analysis, eggs of helminths may not be. Parasites lay eggs is not always, then in the stool are not evenly distributed.
In addition, the results may influence ignoring the rules of preparation for the analysis, the wrong collection and preservation of material.
Therefore, it is necessary to adhere strictly to all the rules for the exam preparation for the analysis, collection, and preservation of the sample, and recognize the need to re-put, if the analysis shows the absence of parasites.
What symptoms may indicate an infestation of worms?
A symptom, indicating the presence of worms is the itching and agitation in the anus, especially tangible in the evening and night. It is typical for enterobiasis – infestations of the pinworms. Infestation of other types of worms is not so obvious and characteristic clinical picture, the symptoms can be unexpressed, or its many other illnesses.
The suspicion of intestinal worms can cause the following symptoms:
- Appetite reduced up to complete her absence;
- Flatulence and intestinal disorders;
- The presence of blood and mucus in the feces;
- Loss of body weight;
- Frequent headaches, sleep disorders;
- The constant feeling of loss of strength;
- The paleness of the skin;
- The weakening of the immune system, expressed in the predisposition to frequent colds;
- Grinding the teeth during sleep;
- Problems of the skin.
When you see at least a couple of these symptoms, it is necessary to pass an examination, including the identification of pest infestations.
How to prepare for the analysis?
To increase the degree of reliability of the result of the analysis of the stool for the egg-worm, it is first necessary to give some rules to follow.
Does not make sense to explore the feces the eggs of worms, in the following cases:
- During the intake of anti-parasitic drugs and immediately after their course;
- After x-ray survey with the use 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 indicative.
Also reduce the effectiveness of studies can the assumption of some powerful drugs. If they are not of vital importance, their intake should be discontinued 3 days before the collection of faeces for analysis.
If the patient is in therapy, which can not be interrupted, for example, a course of antibiotics, then the rest of the analysis of the feces for worm eggs is better to postpone until its end, because in the face of a changed environment in the intestine breeding 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 a person has eaten on the eve of the collection of biological material. The use of products which favor a greater production of gas and losing in the intestine, the food mass, they can accelerate the intestinal tract, and the probability content in the feces of eggs of the pest reduced. Then for 1-2 days before collecting the stool for the analysis on eggs of worms it is recommended to exclude from the diet foods that cause facilitate the bowels.
For each person set of these products is different, but, in general, they are:
- Fresh and sauerkraut;
- Beets;fresh
- Apricots, plums;
- Prunes;
- Grapes;
- Khaki;
- Yogurt;
- Cucumbers, zucchini, pumpkin;
- Legumes;
- Watermelon, melon.
Also, it is not advisable to use the products, coloring the stool color abnormal – already mentioned beets, blueberries, cherries, black currants.
By respecting these simple rules, you can greatly increase the probability of identifying the infestation by helminths and begin timely treatment.
What are the rules for the collection of faeces for analysis?
If you adhere to all the rules of the research training of the feces for the presence of eggs of parasites, referred to above, it is possible to produce the withdrawal of a sample of material for analysis. Usually this time is causing a lot of questions: how great is the need of feces for analysis on an egg-worm, what are the rules for its collection, it is possible to store the material collected, etc. we Consider in detail the answers to these questions.
The laboratory does not take the analysis I did on the boxes and other cardboard boxes, for the collection of material, it is possible to take a small glass bowl with a lid or buy in a pharmacy a special plastic container to collect the stool. This container is convenient because it is equipped with pallet for sample collection and a tight-fitting lid, does not transmit the smell.
Sterilize the glass containers, and even more so – to the pharmacy, there is no need. The jar and the lid is sufficient to clean the baking soda and rinse thoroughly with clean hot water and container for collection falls into the dry does not need.
If the collection is done at the home of tara, which makes it more convenient teaspoon of plastic. You can also use a cotton swab, several of the matches. Use for this purpose are supported with the streets of wood chips and twigs is not possible, because they may be eggs of parasites, which will lead to a distortion of the results of the analysis.
If we dry?
If during the collection of urine is necessary, such as washing, to prevent the entry of biological material of the secretions and microflora that live on the genitalia, while the collection of feces for analysis of worm eggs, such as washing is not recommended.
Some species of helminths (ossiuri) lay their eggs around the anus, in the anus can remain in the eggs of the worms from the previous defecation.
During the passage of stool can be the first portions of the biological material, which increases the probability of identifying the infestation by helminths.
How to collect feces for analysis?
Defecating is necessary in the pure wash of the vessel or of a ship. Are not allowed to "fish" material from the water. Also you need to keep an eye on the feces has not touched the urine, emptying the bladder is necessary in another place.
The material of the enclosure is made from different places of the stool: from the initial cutting, the means and the end, with the surface and the depth. A stool sample for analysis should be approximately equal to the size of a walnut.
Immediately after the withdrawal of the tara is required to close tightly, so that the material is not dried.
How is it possible to call the defecation?
Physiological processes we can't always control the conscience, to force the bowel to emit the waste products on request almost impossible. The easiest way to collect the feces for the analysis on eggs of worms for those who are used to empty the intestine in the morning after waking up, because the lab usually take biological materials for analysis in the morning.
For the stimulation of the gut for emptying, it is not advisable to apply an enema anal candle, because this reduces the probability of obtaining a valid result of the analysis on the egg-worm, which is not too high.
Get the defecation in the morning in the natural way is possible by following the following guidelines:
- After waking up, drink a glass of cold water;
- After 15 to 20 minutes before breakfast;
- If within 20 minutes after the breakfast go to the bathroom, do a self-massage and abdominal exercises to improve intestinal motility.
Self-massage the belly is lying on his back. Relax your belly, put stroking around the navel in a spiral, the direction of the movement, the counter-clockwise movement. More convenient to do so, by squeezing the fingers into a fist.
After the massage, do the following exercises for the stimulation of the bowel-emptying:
- Standing on all fours, draw and distend the stomach;
- Lying on your back, pull your knees up to your chin, and then return to the starting position.
If all these measures had no effect, it means that the material for the analysis will need to collect in advance.
But before moving on to the next point of this article, and find out how you can preserve feces for worm eggs, remember the recommended method of the above-mentioned improvement of intestinal peristalsis. By applying every day, you are quickly accustom your body to adjust to the morning bowel movements, which will no doubt be very useful for your health.
As much as you can to preserve the material collected?
Keep a sample of material for analysis of worm eggs is necessary in a tightly-closed container, knotted in a plastic bag in the refrigerator at a temperature of +6-10°C. In this stock cal does not dry, the eggs of the worms, if present in a sample, vido-change, and will be available for identification. The storage time should not exceed 8-12 hours.
How is the material research in the laboratory?
To determine the presence of eggs of worms in the faeces, and also in the sight of them, the following laboratory methods:
- The defense. With this method the material is mixed with the water, and to defend and drained liquid fraction. So make it a couple of times. The eggs and the steps of helminths have a higher specific weight, then always remain in the sediment. After washing of the residual material visible under the microscope for the presence of parasites.
- In elutriation. This method is used to identify the fragments of helminths. Provided for the analysis of the sample is made semi-liquid mass, its place in a Petri dish and tweezers that remove light particles and view them under a magnifying glass or a microscope. In this way it is possible to identify the steps of helminths and to determine their views.
- A native of the smear. With this method it is examined under a microscope at a drop of the emulsion obtained by diluting the cala water. This allows you to detect the eggs of the worms and protozoan parasites. But with their small amount of material put it, who simply can't get in a drop of interest, with the result that the negative result of the analysis may be a fake.
- The thickness of the smear. In this way, it is more informative, because it allows you to explore a greater amount of material than other methods. The sample size of a pea, placed on a glass slide and lurks polymeric transparent plate, immersed in a liquid. After an hour, the sample acquires the necessary degree of transparency and examined under the microscope. This method is considered to be the most progressive, its validity is about 85%.
The analysis of faeces for egg-worm any of these method does not require a lot of time, the result may be ready for the day of delivery. Delay is usually associated with congestion of the laboratories.
What can be the transcription of the result of the analysis?
The research of cala eggs of helminths can only show the presence or absence of parasites, breeding in the gastrointestinal tract: round and tape worms, and flukes. To identify other helminths, for example, echinococcosis, apply an enzyme immunoassay blood (ELISA).
If the eggs and the steps of the worms surrendered material is not detected, the result of the analysis to decipher will be negative. However, a negative result does not guarantee the absence of pest infestations.
If, after the analysis of the faeces for egg-worm transcription contains a positive result against any type of helminth (or more), and their presence is beyond doubt, and the patient is assigned the treatment.
In addition infestation by helminth, through the analysis of feces may be diagnosed with the infection simple micro-organisms: Giardia, dysenteric amoebae, cyclosporine.
What to do to identify helminthiasis?
If the analysis of faeces for egg-worm revealed the presence in the body of some parasite, which in any case can not refuse the treatment. In addition to the fact that the bot can become an obstacle to achieving the goal – revenue to school or work, devices of the preschool child, getting health care, portable, etc., can cause serious damage to your health.
Parasites in human feed on its life juices, choose the energy. In addition, because of their reduced immunity, which can lead to the development of even more serious diseases.
Even more unacceptable and self-medicate. Pesticides are characterized by high toxicity. Even if the type of parasite known, the dosage of the medication, effective against him, it must be installed only by a physician, taking into account all the data and physical conditions of the patient. The treatment should take place under the supervision of a specialist, otherwise it may cause severe complications caused toxic anthelmintic.
In addition, we must not forget that the eggs of the worms are easily transmitted through objects of daily use, with the personal contacts. Therefore, when you encounter a pest infestation of man, requires the examination and, if necessary, the treatment of other members of the family, including pets.
As is often the need of exams?
Usually the analysis of faeces for egg-worm only lost once when you receive the school and educational institutions, at work, in a hospital, nursing home, and the moment of reference for the swimming pool, but also during the passage of a clinical examination.
