Analysis of the feces the eggs of worms often given to identify the carriers of helminths to prevent the spread of parasitic infestation a group of common people.
Mandatory submission of this analysis, workers in catering and other professions that require a health book, it is also necessary to the admission of children in kindergartens and educational institutions, when applying for a job, hospital treatment, access and care, you can visit the swimming pool.
In addition, the study of fecal egg worm can be defined as diagnostic measures for suspected intestinal helminths. The accuracy of the laboratory results depends largely on how correctly was fixed biological material. This article covers all the issues related to the delivery of the analysis of feces on eggs a worm for kids and adults.
Why do we need analysis?
To take the analysis of the feces the eggs of worms is not a formal approach. The person he addressed to have to understand that the identification of helminth infestation it is important, above all, to himself. After all, parasites cause serious harm, some species are able to penetrate the liver, brain, heart and other organs.
Laboratory studies of stool does not always reveal an infestation, because of the small sample of biological material put on the analysis of the helminth eggs can be. Parasites of eggs is not constant, so the stool unevenly.
In addition, the results can affect a disregard for the rules of preparation for analysis, the incorrect collection and storage of the material.
It is therefore necessary to strictly follow all the rules of preparation for analysis, collection and storage of the sample and to understand the necessity of re-taking, if the analysis shows the absence of parasites.
What symptoms may indicate infected worms?
The symptom clearly indicates the presence of worms is the itching and wiggling the anus, especially noticeable in the evening and at night. It is typical for enterobiasis – infestation of pinworms. Attack other worms are not so obvious and typical clinical picture, the symptoms can be new, or there 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 stool;
- Weight loss;
- Frequent headaches, sleep disorders;
- A constant feeling of fatigue;
- Pallor of the skin;
- A weakened immune system causing susceptibility to frequent colds;
- Grinding teeth sleep;
- Skin problems.
The appearance of at least a few of these symptoms, is explored, including the identification of parasitic infestation.
How to prepare for the analysis?
To improve the reliability of the result analysis, fecal egg worm, is required prior to submission to comply with certain rules.
Does not make sense to examine feces on eggs of helminths in the following cases:
- When taken anti-parasitic drugs and immediately after their period;
- After radiographic examination using barium preparations;
- When the oil enema.
In all these cases, the probability of detecting helminth eggs is close to zero, and the results of the analysis should not be revealing.
Also reduce the performance of the research may be taking some powerful drugs. If they are not vital, their admission should be discontinued 3 days before collection of stool sample.
If the patient is in treatment, which can not be interrupted, for example, a course of antibiotics, delivery-analysis of the feces the eggs of worms it is better to postpone until the end, because of the changed environment in the intestine the reproduction of the worms is slowing down, and their eggs cannot be detected.
Is the impact of the results of the study and the composition of the food that people ate before the collection of biological material. Use products that increase flatulence and loose stools, the food delivery quickly to pass the bowel, and the probability content of the feces of the parasite eggs is reduced. So 1-2 days before the collection of feces analysis on helminth eggs it is recommended to remove from the diet foods that cause loose stools.
Each person's collection of these products separately, but in General, these are:
- Cabbage and sauerkraut;
- Fresh beets;
- Apricots, plums;
- Prunes;
- Grapes;
- Persimmon;
- Yogurt;
- Cucumber, zucchini, pumpkin;
- Bean;
- Watermelon, melon.
Also not recommended to use the products, staining of stool in unusual colors – the already mentioned beets, blueberries, cherries, black currants.
Stick to these simple rules, you can significantly increase the likelihood of identifying helminth infection and the timely initiation of treatment.
What are the rules to collect feces for analysis?
If you have followed all the rules for the preparation of the study of feces for the presence of parasite eggs to the above, it is possible to produce a sample of material for analysis. Usually, this point raises many questions: how much feces analysis on eggs a worm, what are the rules of its collection, is it possible to save the collected material, etc. let us consider in detail the answers to these questions.
The laboratory will not accept for analysis a stool to match and other cardboard boxes, a collection of material, you can take a small glass container with a tight lid or buy in a drugstore special plastic container for collection of feces. This packaging is convenient because it is equipped with a shovel to collect the sample and close the lid, which does not pass the smell.
Sterilize a glass container, especially the pharmacy, there is no need. The jar and lid is enough to clean with baking soda and rinse with clean hot water and a container to collect feces in the wash is not needed.
If collection is done at home in containers, so it is a handy disposable spoon. You can also use a cotton swab, the number of matches. Used for this purpose, chips, chips and not sticks, because they may be the eggs of parasites, which distort analysis results.
Do I need to wash?
If the collection of urine must be washed off, to avoid obtaining a biological material, secretions and microflora, which lives on the genitals, when collecting feces analysis on helminth eggs wash is not recommended.
Some species of helminths (pinworms) eggs around the anus, including the anus could stay helminth eggs from the previous defecation.
When passing a stool, they may be the first part of the biological material, which increases the probability to recognize the risk of helminth infection.
How to collect feces for analysis?
It is necessary to defecate in a clean dry pot or container. Not get "caught" on the material, the water in 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 manufactured in several places in the feces: the original segment, the middle and the end, surface and depth. Stool samples for analysis should be approximately equal to the size of a walnut.
Immediately after collection, containers should be tightly closed, the material does not dry.
How to cause a bowel movement?
Physiological processes do not always apply mind control, forcing the bowels to lay waste to the demand for products is almost impossible. The easiest way to collect feces 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 to test in the morning.
To promote the bowel to empty is not recommended to use enemas, butt plugs, because it reduces the likelihood of getting a reliable analysis of the resulting 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, eat Breakfast;
- If 20 minutes after Breakfast 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 the stroking pole of the spiral, the direction of movement – clockwise. It is easier, 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;
- Lie on your back, pull your knees up to the chin, and then return to the starting position.
If all the above measures had any effect, it means that the analysis is collected in advance.
But before you can move on to the next paragraph of this article and figure out how much you can save fecal worm eggs, other the above the recommended way to improve intestinal motility. Apply it on a daily basis, you can quickly train your body regularly in the morning bowel movement, which no doubt is very useful for 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 6-10°C. this storage, the stool is not dry, the eggs of worms, if present in the sample, species-change, and is available for identification. The storage period should not exceed 8-12 hours.
How is the study of the material in the lab?
Determine the presence of eggs of worms in the feces, as well as their type, the following methods of laboratory research:
- Defensive. In this method the material is mixed with water, settled and decanted the liquid fraction. Do it a few times. The eggs and fragments of helminths has a higher specific weight therefore they always remain in the sediment. After repeated washing of the precipitate material can be seen under a microscope and parasites.
- In elutriation. This method is used to detect fragments of the worms. If the analysis of the sample made semi-fluid mass, and it was placed in a petri dish and the tweezers to remove the light particles, examined them with a magnifying glass or microscope. This can be identified by the pieces of worms and define them.
- The native language of the smear. In this method, under a microscope studied only one drop of the emulsion, which is obtained by diluting the feces with water. This allows to detect helminth eggs and protozoan parasites. But the small amount of deposited material, they can simply not let the population drop, resulting in a negative result of the analysis can 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 placed on the glass plate and pressed against the transparent polymer plate is immersed in the liquid. An hour later, the sample to acquire the necessary transparency and examined under a microscope. This method is considered the most progressive, its accuracy is about 85%.
By performing analysis, fecal egg worm in any 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 be the decryption result of the analysis?
The study of 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. Detect other helminths, for example, echinococcosis, which is used for enzyme-linked immunosorbent assay (ELISA).
If the eggs and the fragments of the worms deposited material is not detected, the analysis result of the decoding is negative. However, a negative result does not guarantee that an infestation.
If after that, put fecal egg worm transcription contains a positive result against any of the worms (or more), their presence is undeniable, and the patient is prescribed treatment.
In addition, worm infection, a stool sample can be used to diagnose protozoan infection infections: Giardia lamblia, dysenteric amoebas, cyclosporine.
What to do when you detect a bot?
If the analysis of fecal egg worm showed the presence in the body of any parasites, then in any case can not refuse treatment. In addition, that the bot can become a barrier to achieve the goal – admission to work or school, place the child in the day home, to get medical 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 acceptable and himself. Parasites products are of high toxicity. Although the form of the parasite is known, the dosage of the drug effective against him, should be installed only by a doctor, all the physics and the condition of the patient. Treatment should be under the supervision of a specialist doctor, otherwise there may be serious complications caused by the toxic effect of Anthelmintics.
You should also not forget that eggs and worms are easily transmitted through household items, and personal contacts. Therefore, the detection of parasitic infestation in humans medical examination and treatment if necessary, other family members, including Pets.
How often should I get tested?
Typically, the analysis of fecal egg worm show time receipt in kindergartens and schools, at work, in a hospital, sanatorium, when referring to a swimming pool, and examination.
