Information that 80-90% of people are infected with worms, many people end up with the idea that you should drink anthelmintic drugs for a precautionary purpose.
The human body parases different types of worms, specific tests have been developed for their identity.Each diagnostic procedure has a certain rate of credibility and differs in the characteristics of behavior.
Blood tests for pests
The vital activity of pests in the body causes unpleasant vague etiology.They can be skin rashes, flatulence, heartburn, nausea, weakness, anemia, joint pain.In order to clarify the diagnosis, special parasite tests must be performed.
How to check for parasites in the human body
Sorting pests in their appearance:
For representatives of certain professions (for supply business staff, children's institutions), worms are required for worms in the design of healthy books.Children pass the same resolution when entering kindergartens and in a nursery or a sports section.
- A classic study on worms living on the gastrointestinal tract is an analysis of the feces and the scraping of the mucosa by the rectum.
- But there are several options for more effective blood tests for pests, as provided for in the method.
Reasons to provide analysis for parasites
When infected with individual pests, a person may not feel symptoms.But over time, the number of helmets increases and the infection begins to manifest.It is necessary to test for parasites if there are such symptoms:
- Abdominal pain of different location, which can occur spontaneously or in palpation.
- Itching in the anus that occurs at night.
- joint and muscle pain.
- Reduced appetite and nausea.
- Increased appetite with plenty of saliva.
- Intestinal dysfunction.
- constipation or diarrhea.
- Change in the color of feces.
- Increased fatigue.
- dizziness;
- The crap of the skin.
- insomnia or sleep disorders.
- Irritable?
- Dermatitis.
- urine incontinence.
- In women, plenty of vaginal discharge, menstrual cycle violations.
The nature of the symptoms depends on the type of pests.Itching and burning in the anal area cause pinworms.Askarides causes serious allergic reactions as well as abdominal pain.Lambia, echinococcus and swelling affect the liver.It is often the cause of biliary pathway and cholesterol (stagnation of bile), inflammation of the gall bladder.Lightweight feces with fat drops are one of the main signs of liver and pancreas pathology.The symptom of the parasitic effect on the liver and gall bladder is the pain in the right hypochondriac.
If many of the reported symptoms occur, it is necessary to go to the hospital to locate the pests in the body in time.It is necessary to receive regular preventive tests for parasites for children, people who live or work with animals.If the raw, crazy, slightly salted meat, lard or fish are regularly consumed for food, the risk of infection is very high.In this case, it is also necessary to check regularly to identify the pests.
Which tests for pests are there
There are several reasons that cause the need to take analysis for helminths.
In this parameter, 3 types of tests are distinguished:
- Preventive - necessary for the timely detection of helminth, even in the absence of characteristic symptoms.Are conducted in a person's personal initiative or medical examination.It is advisable to receive such an analysis every year, especially for children.
- The barrier - is prescribed to minimize the risk of spreading helminth between the population.This is a compulsory analysis that children go through before entering a kindergarten or school, food workers, service areas, medical staff to obtain a medical book.The barrier resolution is provided once a year.
- As provided by a physician, this type of analysis for helminths is prescribed by a doctor in the presence of symptoms that characterize helminth: nausea, stomach disorders, anus itching, weight loss, abdominal pain, increased fatigue, dizziness.With a single negative effect, the analysis must be re -taken to ensure its reliability.
Depending on the condition and symptoms, one or more test types are prescribed.Let us consider in detail the characteristics of each.
With a sharp weight loss, you should consider the need to carry out parasites
Calais resolution for worm eggs
Analysis of pest feces, in other words, is called a Coprogram-A method that provides for the study of the stools under a microscope to detect pest eggs, their larvae or fragments of sexually mature worms.This analysis makes it possible to identify many varieties of worms, but is particularly effective for worms that give up in the intestines.Suitable for the diagnosis of enterobilization, Askaria, hook, tricolosis and other types of infection.
To perform an analysis, you need to take a special sterile jar.Issued in clinic, laboratories or purchased in a pharmacy.
Then everything is simply:
- It is necessary to complete 1/3 with stool stools.This should be done before 11.00 hours.Make sure the third dirt, for example, blood, the drops of other secretions do not fall into the jar, as this will negatively show the reliability of the result.
- The cap of filled capacity should be tight.Signed and then packaged in a disposable package.
- It is better if the material can be transferred for 30-45 minutes after collection.Store in the refrigerator, but not more than 8 hours.After this period, the material becomes inappropriate for analysis.
You can find out the results on the day after the analysis.But in some laboratories up to 6 days.
The effectiveness of this method is 30-35%, as the elm do not put eggs every night.
Abrasion (coating)
Scraping is the most common resolution for enterobilization, which allows you to determine the presence of table tennis in the intestines and have set a large number of eggs in the area around the anus, as well as in the perineum area every night.
Since children are especially often suffering from enterobilization, a child visiting a kindergarten, a school, should take a scraping regularly twice a year.Adults also have to do an analysis when the first signs of pests occur: itching on the anus, bad sleep, worsening appetite, weight loss, irritability.
Analysis Procedure:
- The scraping is taken from a special spatula, which is available in the pharmacy, or with a common cotton wool, previously moistened in saline or hot water.They remove a coating from the area around the anus as well as the perineum.Another way is to attach a sticky film (film) to the area around the anus.Remove gently, should be glued to the surface of the clean and dry glass.
- The procedure must take place in the morning immediately after awakening.Before that, you can't go to the toilet and wash.You can get a coating in a clinic or at home.
- A stick or spatula, on the surface of which there is a biomass for research, is packaged in a sterile dry jar, package.The package must be sealed.
- It is necessary to deliver the material to the laboratory for research on the day of taking a coat, it is better immediately.If necessary, for a maximum of 5 hours, it can be stored in the refrigerator.
You can find out the results the next day.
If the results of the first analysis were negative, but the symptoms that are characteristic of enterobilization are maintained, the process must go through the next day or every second day.Maximum efficiency guarantees a 3-4 negative effect of the analyzes performed in a row.
Blood test
A blood test shows the presence of pests, because as a result of their lives, they affect the internal organs, the mucous membranes, release a large number of toxins.This causes changes in blood composition.When elminths appear, the immune system begins to produce antibodies (immunoglobulin).Can be identified as a result of the study.
The main thing is that there is a sufficient decoding of the results, which can only be done by an experienced specialist.
A blood test for parasites determines all their varieties - Ascaride, Lamblia, Flat Worms, two -water, Trichinella, Trematodes.Most of them are parasitized in the internal organs: in the liver, in the lungs, in the conductors and not in the intestines, so using other tests, it will not work to identify these types of pests.
Analysis Procedure:
- To make the analysis, venous blood is required.It is sufficient to obtain 3-5 ml of material from the elbow vein.The process is performed on an empty stomach, preferably in the morning.
- Experts study the selected blood in the laboratory for specific antibodies, which allow you to determine the stage of helminth.
- Decrypting the results of the analysis.
Before blood donation, the patient must cross the preparation stage.It begins a week before diagnosis and implies a complete refusal to use antibiotics and other drugs, the composition of which can adversely affect the accuracy of the result.The day before the analysis, it is worth excluding fatty products, sweets, carbonated drinks and always alcohol from nutrition.
Determination of helminth invasion is also performed using a general blood test.It is quite informative, allows you to identify different types of worms, but more effective than pinworms as well as Ascaris.
When decrypting the general analysis, the following indicators are taken into account:
- Hemoglobin - with worms damage, decreases.
- Leukocytes - when infected with helminths, their concentration increases.
For analysis, blood is taken from a vein.Before the process, it is important not to eat 8, but better than 12 hours.You are allowed to drink water only.5-7 days before manipulation, it is necessary to stop taking antibiotics.
Elisa, analysis for antibodies and immunoglobulin
This analysis is based on the body's immune response, the level of its protective reaction to the pest invasion.
- Using the results of Elisa, you can determine the presence of helmets in their body and type.The accuracy of the study is much higher than the analysis of the feces.
- The method is based on the calculation of antibodies in the body in one pest or the other type of pests, the determination of their relationship with foreign antigens (immune response) and the enzymatic reaction of the body.
- Antibody antibodies indicate an infection.
- A blood test by Elisa has accuracy, according to different experts, from 60% to 90% even at the low invasion level.
- The advantage of the method, in addition to a high level of accuracy, is that an immune -function analysis can be monitored by the dynamics of the disease over time.
Chain Polymerase Reaction (PCR resolution)
The PCR method is one of the most modern and accurate to diagnose blood for the presence of pests in the body.It consists of the detection of DNA and RNA traces, which belong to parasitic forms of life.
- The essence of the polymerase reaction is blood treatment in such a way as to copy and spread DNA, RNA of foreign organisms at a concentration that allows them to determine.
Serological testing blood
At the same time, the analysis is used as a source of blood serum information.
- Immunogeneous pest antibodies are examined.
- The analysis allows you to identify a large number of parasitic forms, but it does not allow you to determine the stage of the invasion.
- Like the IFA method, serological analysis is indirect for diagnosis.
- If the OPD values are high, it is advisable to pass the stool analysis.
How and where to do tests for pests
It is necessary to take tests for pests when symptoms that are characteristic of helminth invasion occur: digestive problems, illness, weight loss, dermatological diseases.It is also necessary to undergo algae diagnostics in situations where a person has chronic illness for many years, but treatment does not give the expected result.In many cases, it turns out that the disease is not caused by normal problems, but with the consequence of worms.
Before passing the procedure, you must take a direction from a gastroenterologist, special infectious disease, proctologist, therapist, surgeon, dermatologist and pediatrician.In this direction, a person goes to the lab.After studying biomaterials, it receives a form of results, which indicates whether they are detected.
If the results of the analysis have confirmed the presence of worms, it is important to consult a specialized doctor immediately.May be a specialist or therapist of infectious disease.When Helminthiasis is diagnosed with a child, a pediatrician will help.
To do tests that detect pests are needed at least once a year.To undergo a diagnosis, it is important to choose a good laboratory whose experts guarantee the maximum accuracy of the results.
