Information that 80-90% of people are infected with worms, many people think of the idea that they need to drink antihelmintic drugs for a preventive purpose.
The parasite human body different types of worms, special evidence has been developed for identification.Each diagnostic procedure has a certain percentage of reliability and differs in the characteristics of behavior.
Blood analysis for parasites
The vital activity of parasites in the body causes discomfort of unclear etiology.It can be skin rashes, flatulence, stomach acidity, nausea, weakness, anemia, joint pain.To clarify the diagnosis, special tests for parasites must be performed.
How to verify if there are parasites in the human body
Classification of parasites in their appearance:
For the representatives of some professions (for catering companies, children's institutions), worm eggs analysis is required in the design of sanitary books.Children pass the same analysis when entering the kindergartens and a nursery or in a sports section.
- A classic study on worms living in the gastrointestinal tract is an analysis of the feces and a scraping of the mucosa of the rectum.
- But there are several more effective blood analysis options for parasites, as planned and according to the method.
REASONS FOR THE DELIVERY OF ANALYSIS FOR PARASITES
When infected with individual parasites, a person may not feel any symptoms.But over time, the number of helminths increases, and the infection begins to manifest.It is necessary to take parasite tests if there are such symptoms:
- abdominal pain of a different location, which can occur spontaneously or on palpation;
- itching in the anus that appears at night;
- joint and muscular pain;
- reduced appetite and nausea;
- greater appetite with abundant salivation;
- intestinal dysbiosis;
- constipation or diarrhea;
- change in the color of the feces;
- greater fatigue;
- dizziness;
- the paleness of the skin;
- Insomnia or sleep alterations;
- irritability;
- dermatitis;
- urine incontinence;
- In women, the abundant discharge of the vagina, the violations of the menstrual cycle.
The nature of the symptoms depends on the type of parasites.Itching and burning in the anal region cause plug worms.Askarides causes severe allergic reactions, as well as abdominal pain.Lambia, equinoxes and bicondumura affect the liver.They are often the cause of the obstruction of the biliary tract and the cholestasis (stagnation of the bile), the inflammation of the gallbladder.Light stool with fat drops are one of the main signs of liver and pancreas pathology.The symptom of the parasite effect on the liver and gallbladder is pain in the right hypochondrium.
If several of the listed symptoms appear, it is necessary to go to the hospital to identify parasites in the body in time.It is necessary to perform regular preventive tests for parasites for children, people who live or work with animals.If the meat, butter or raw fish, cecina and slightly salty is consumed regularly for food, the risk of infection is very high.In this case, it is also necessary to regularly verify to identify parasites.
What tests of parasites exist
There are different reasons that cause the need to take an analysis for helminths.
In this parameter, 3 types of tests are distinguished:
- Preventive: necessary for the timely detection of Helmintiasis even in the absence of characteristic symptoms.They are carried out in the personal initiative of a person or in a medical exam.It is recommended to perform such an analysis every year, especially for children.
- Barrera: They are prescribed to minimize the risk of propagation of helminthiasis among the population.This is a mandatory analysis that children pass before entering a garden of infants or school, food industry workers, service areas, medical staff to obtain a medical book.Barrier analysis is provided once a year.
- As prescribed by a doctor, this type of analysis for helminths is prescribed by a doctor in the presence of characteristic symptoms of helminthiasis: nausea, stomach disorders, itching in anus, weight loss, abdominal pain, greater fatigue, dizziness.With a single negative result, the analysis must be taken again to ensure its reliability.
Depending on the situation and symptoms, one or more types of tests are prescribed.Consider in detail the characteristics of each one.
With strong weight loss, you should think about the need to perform parasites analysis
Calais analysis for worm eggs
The analysis of the feces for the parasites, otherwise, is called a coprogram-A method that provides the study of fecal masses under a microscope to identify parasites eggs, their larvae or fragments of sexually mature worms.This analysis allows you to identify many varieties of worms, but it is especially effective for worms that parasitize in the intestines.Suitable for the diagnosis of enterobiosis, ascariasis, anquylostomosis, trichocephalyosis and other types of infection.
To perform an analysis, you must take a special sterile bottle.It is issued in a clinic, laboratories or purchased in a pharmacy.
So everything is simple:
- It is necessary to complete 1/3 with feces with feces.This must be done before 11.00.Make sure the impurities of the third game, for example, blood, falls from other secretions do not fall into the bottle, since this will negatively show the reliability of the result.
- The full capacity cover must be firmly closed.It is signed and then packaged in a disposable package.
- It is better if the material can be transferred for the analysis of 30 to 45 minutes after the collection.It is allowed to store it in the refrigerator, but no more than 8 hours.After this period, the material becomes inappropriate for the analysis.
You can find out the results on the day after analysis.But in some laboratories it is done up to 6 days.
The effectiveness of this method is 30-35%, since the helminths do not put eggs every night.
Scrape
The scraping is the most common analysis for enterobiosis, which allows it to identify the presence of worms that parasitize in the intestines and place a large number of eggs in the area around the anus, as well as in the area of the perineum every night.
Since children often suffer from enterobiosis, a child who visits a kindergarten, a school, must take a regular scratch twice a year.Adults should also make an analysis when the first parasites signs appear: itching in anus, bad sleep, worsening of appetite, weight loss, irritability.
ANALYSIS PROCEDURE:
- The scraping is taken by a special spatula, which is available in the pharmacy, or with an ordinary cotton wool, previously moistened in a saline solution or warm water.Eliminates a smear of the area around the anus, as well as the perineum.Another way is to join an adhesive tape (tape) to the area around the anus.It was gently removed, should be hit to the clean and dry glass surface.
- The procedure must be carried out in the morning, immediately after waking up.Before that, you can't go to the bathroom and wash yourself.You can take a stain at a clinic or at home.
- A stick or a spatula, on the surface of which there is a biomass for research, is packaged in a sterile dry jar, package.The packaging must be sealed.
- It is necessary to deliver the material to the laboratory for research on the day of taking a stain, 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 typical symptoms of enterobiosis are preserved, the procedure must pass again the next day or every two days.The maximum effectiveness guarantees 3-4 negative result of the analyzes performed in a row.
Blood test
A blood test shows the presence of parasites, because as a result of their life, they affect the internal organs, mucous membranes, release a large number of toxins.This causes changes in the composition of the blood.When helminths appear, the immune system begins to produce antibodies (immunoglobulin).They can be identified as a result of the study.
The main thing is that a competent decoding of the results is carried out, which can only be carried out by an experienced specialist.
A blood test for parasites determines all its varieties: Ascarido, Lamblia, flat worms, two water, trichinella, trematodes.Most of them parasitize in the internal organs: in the liver, the lungs, the ducts and not in the intestines, therefore, using other tests, it will not work to identify this type of parasites.
Analysis delivery procedure:
- To make the analysis, venous blood is needed.It is enough to take 3-5 ml of elbow vein material.The procedure is carried out with an empty stomach, preferably in the morning.
- The specialists study the selected blood in the laboratory for specific antibodies, which allow it to determine the stage of hemmintiasis.
- Decipher the results of the analysis.
Before donating blood, the patient must pass the preparation stage.It begins a week before diagnosis and implies a complete negative to use antibiotics and other medications, whose composition can negatively affect the precision of the result.One day before the analysis, it is worth excluding fatty products, sweets, carbonated drinks and always diet alcohol.
The determination of the helminthic invasion is also carried out using a general blood analysis.It is quite informative, allows you to identify different types of worms, but more effective in relation to the plug worms, as well as Ascaris.
When the general analysis decipher, the following indicators are taken into account:
- Hemoglobin: with worm damage, it is reduced;
- Leukocytes: When infected with helminths, their concentration increases.
For the analysis, the blood is taken from a vein.Before the procedure, it is important not to eat 8, but better than 12 hours.It is allowed to drink only water.5-7 days before manipulation, it is necessary to stop taking antibiotics.
Elisa, antibody and immunoglobulin analysis
This analysis is based on the immune response of the body, the level of its protective reaction to the invasion of parasites.
- Using Elisa's results, you can determine the presence of helminths in the body and its type.The precision of the study is much greater than the analysis of the feces.
- The method is based on the calculation of antibodies in the body to one or another type of parasites, the determination of its connection with strange antigens (immune response) and the enzymatic reaction of the body.
- Anti-antigen antibodies indicate an infection.
- A blood analysis of Elisa has precision, according to different experts, from 60% to 90% even at the low level of invasion.
- The advantage of the method, in addition to a high level of precision, is that an immunomanfunction analysis can be monitored by the dynamics of the disease over time.
Polymerase chain reaction (PCR analysis)
The PCR method is one of the most modern and precise for blood diagnosis for the presence of parasites in the body.It consists of detecting DNA and RNA traces, which belong to parasitic ways of life.
- The essence of the polymerase reaction is the treatment of blood in such a way that the DNA, the RNA of foreign organisms to a concentration that allows them to determine.
Serological blood analysis
At the same time, the analysis is used as a source of information from the blood serum.
- Immunogenic antibodies of parasites are investigated.
- The analysis allows you to identify a large number of parasitic forms, but it does not allow you to determine the invasion stage.
- Like the IFA method, serological analysis is indirect for diagnosis.
- If the OPD values are high, it is advisable to also pass the fecal analysis.
How and where to take tests for parasites
It is necessary to take parasite tests when the typical symptoms of the helmi -invasion appear: digestive problems, asthenia, weight loss, dermatological diseases.It is also necessary to submit to diagnoses for helminths in situations where a person suffers from a chronic disease for many years, but the treatment does not give the expected result.In many cases, it turns out that the disease is caused not due to physiological problems, but as a result of the parasitization of worms.
Before passing the procedure, you must obtain an address of a gastroenterologist, a specialist in infectious diseases, proctologist, therapist, surgeon, dermatologist and pediatrician.With this address, a person goes to the laboratory.After the study of biomaterials, it receives a form of results, indicating whether the helminths are detected in the body.
If the analysis results confirmed the presence of worms, it is important to immediately consult a qualified doctor.It can be an infectious or therapist disease specialist.When Helmintiasis is diagnosed in a child, a pediatrician will help.
Taking evidence that identifies the parasites need at least once a year.To undergo diagnoses, it is important to choose a good laboratory, whose specialists guarantee the maximum precision of the results.
