1 Indications for helminth studies

This analysis is performed for diagnostic and prophylactic purposes:

1. Diagnostic study is done in the presence of patient complaints of itching in the anus, bad sleep, insomnia, pallor of the skin, weight loss, disruption of the gastrointestinal tract,manifested in the form of periodic diarrhea or constipation, the emergence of allergic reactions, reducing the overall immunity and other symptoms of helminthic invasion. After all, despite the fact that very often the diagnosis of helminthic invasion can not be doubted, it is absolutely necessary to know the type of parasite, since some anthelminthic drugs act selectively and can not help to effectively get rid of them. Therefore, in order not to expose the body to the uncontrolled effect of antihelminthic drugs, which are by no means harmless, you need to know exactly the type of helminth. And this can only be determined in a laboratory. In addition, the study is conducted to monitor the effectiveness of treatment of helminthic invasion.

2. Preventive tests should be given to all people who have been in contact with a patient infected with parasites. After all, helminthiases are a disease of dirty hands, which are very easily transmitted to everyday life through household items. Also, the diagnosis of the presence of helminths in the body should be carried out in the event that a person accidentally drank contaminated water, or used raw water from aboveground sources - rivers, lakes, streams. After all, under these conditions there is a very high probability that the eggs of the helminths, which are very stable in the environment, can enter the human gastrointestinal tract and can remain viable for a long time in the soil, water and other places.

2 Collection of a sample for the diagnosis of parasites

How to pass the analysis? Special preparation for the research is not needed, but certain restrictions must be observed. Primary research is desirable to hold before taking antibacterial and anthelmintic drugs. For 3 days prior to the day of the study, drugs that promote intestinal peristalsis and laxatives should not be taken. In addition, it is desirable to refrain from eating foods that have coloring properties.

If it is necessary to conduct a comprehensive diagnosis of the health of the human body, some studies, such as irrigoscopy( colon examination), should be done no later than 2 weeks before the helminth test.

You should prepare the dishes in advance, in which you will need to collect the material. To do this, you can use a clean and dry glass or plastic jar with a lid. However, the easiest way to buy a pharmacy is a special disposable container for collecting feces, which is equipped with a spoon.

For the study, you can take only the material obtained by natural means. In no case should samples be taken from faeces that are obtained with enemas, laxatives or candles. In this case, the result will not be sufficiently reliable. Therefore, it may be necessary to re-conduct the diagnosis.

3 How to select the material?

Planning to do feces analysis on egg worm, how to donate the material?

The sample for the study is collected at home and delivered over several hours to the laboratory.

Cal at eggs of parasites can be selected not only on the day of the planned study, but also on the eve. The main thing is that the sample is stored in the refrigerator at a temperature of no higher than 3-4 ºC.The jar should be tightly closed, signed and delivered to the laboratory for research. However, to obtain the most accurate result, the biomaterial should be collected and delivered to the laboratory for 30-40 minutes.

The feces are collected from different parts of the faeces. In this case, samples should be taken not only from the outside, but also from the inside. The total volume of material for the study should be at least 1-2 tsp. If the test is to be passed on to a child, it must be ensured that urine is not included in the test sample. This can distort the results.

In order to obtain the most reliable results, this study should be conducted at least 3 times. And only in the case of 3 negative test results can we say that in the stool eggs of worms are not found. In some cases, even a six-fold study may be necessary.

How much analysis of feces is performed on egg worm? After all, you will probably need a doctor's second consultation on the results of the tests. Therefore, you need to plan your time in advance. The study is carried out under a microscope, so the lab technician can give out the result in just 10-15 minutes. However, due to the fact that the workload of the laboratories is high, the results are given either in the afternoon of the day on the day of the study, or the next day.

In normal analysis of stool there should be no live parasites, their fragments and eggs. With the help of this method, eggs or fragments of various species of round worms, flukes and cestodes can be found in the feces.

4 Scraping for enterobiasis

Study of feces on eggs The worm basically does not show the presence of pinworms in the human body. This is due to the physiological characteristics of the life cycle of this parasite. Unlike other types of worms, a female pinworm lays eggs in the perianal region, and not in the human intestine. Therefore, when you study the contents of the intestine on the egg egg, you will almost always get a negative result.

To determine the presence or absence of pinworms in the human body, you do not need to hand over the stool. For this study, it is necessary to scrape the enterobiosis from the perianal folds. In addition, to obtain the most accurate result, this analysis must be done several times, at least three times. After all, the female parasite does not lay eggs every day, so the results can be negative. In addition, due to the fact that the female lays eggs at night, before passing the tests do not need to do morning hygiene procedures so as not to wash them off.

Scraping for enterobiasis can be done in the following ways:

1. Using adhesive tape. It is necessary for a couple of seconds to paste a small piece of adhesive tape on the perianal area and then transfer it to a slide.
2. with a cotton swab. This method can be used only under the condition of immediate examination of the smear under the microscope. To do this, the cotton swab should be lubricated with glycerin and gently rub the skin in the anus area.

The main condition for obtaining correct results is almost immediate examination of samples. When performing the analysis more than 2 hours after taking the smear, the result is considered uninformative.

Scraping for enterobiasis is carried out not only with a diagnostic purpose in the presence of complaints, but also with preventive. For example, it is necessary to examine all members of the patient's family with enterobiasis. Also, this analysis is mandatory for all children who are registered in medical and preventive and preschool institutions. After all, if the patient is detected in time, he can be quickly isolated so that others do not pick up the pinworm.
