Information that are 80-90% of people infected with worms, many people come up with the idea that you need to drink anthelmintic drugs for preventive purpose.
The human body parasites different types of worms, special tests have been developed for their identification.Each diagnostic procedure has a certain percentage of reliability and differs in behavior characteristics.
Blood tests for parasites
The vital activity of the parasite in the body causes the weakness of vague etiology.It can be a rash on the skin, bloating, heartburn, nausea, weakness, anemia, joint pain.To clarify the diagnosis, special tests for parasites should be performed.
How to check parasites in the human body
Parasite classification in its appearance:
For representatives of some occupations (for catering enterprise staff, children's institutions), the analysis of the worm eggs is needed in the design of sanitary books.Children bring the same analysis after admission to kindergartens and kindergarten or in the sports part.
- A classic study on worms living in the gastrointestinal tract is an analysis of feces and scraping mucosa from the rectum.
- But there are several options for more efficient blood tests for parasites, as intended for the method.
Reasons for delivery analysis for parasites
When infecting some parasites, a person may not feel any symptoms.But over time, the number of helmimans increases, and the infection begins to manifest.It is necessary to take tests for parasites if there are such symptoms:
- Abdominal pain of different localizations, which may appear spontaneously or palpation;
- itching in an anus that appears at night;
- Joint and muscle pain;
- Reduced appetite and nausea;
- Increased appetite with abundant salivation;
- Intestinal Dimbiosis;
- prison or diarrhea;
- Change in color of feces;
- increased fatigue;
- dizziness;
- pale skin;
- insomnia or sleep disorders;
- irritability;
- dermatitis;
- Incontinence of urine;
- In women, abundant discharge from the vagina, violation of the menstrual cycle.
The nature of the symptom depends on the type of parasite.Itching and ignition in the anal region cause Pinworms.Askarides cause serious allergic reactions, as well as spasms in the abdomen.Lambia, Echinococci and biconducta affect the liver.They are often the cause of biliary tract obstruction and cholestasia (Žela stagnation), inflammation of the gallbladder.Light feces with drops of fat are one of the main signs of liver pathology and pancreas.The symptom of parasites on the liver and bile bladder is pain in real hypochondria.
If several symptoms appear, it is necessary to go to the hospital to identify parasites in the body in the body.It is necessary to take on regular preventive tests for parasites for children, people living or working with animals.If raw, light salty meat, lard or fish are regularly consumed for food, the risk of infection is very high.In this case, it is necessary to check regularly to identify parasites.
What tests are there parasites
There are different reasons that cause the need to be analyzed for Helminthe.
These parameter differ 3 types of tests:
- Preventively - necessary for timely detection of helmintis even in the absence of characteristic symptoms.They are performed on a person's personal initiative or medical examination.It is recommended to download such an analysis each year, especially for children.
- Barrier - are prescribed to reduce the risk of expanding Helmists among the population.This is a mandatory analysis that children pass before entering kindergarten or school, food workers, service areas, medical staff for medical staff.The barrier analysis is provided once a year.
- As prescribed by a doctor, this type of analysis for Helminthe prescribes a doctor in the presence of symptoms characteristic of Helminthiasis: nausea, stomach disorders, abdominals, greater fatigue, dizziness.One negative results, the analysis must be re-undertaken to ensure its reliability.
Depending on the situation and symptoms, one or more types of tests are prescribed.Consider the detailed characteristics of each.
With a sharp weight loss you should think about the need to conduct analyzes for parasites
Calais analysis for CRM eggs
The analysis of the feces for parasites, otherwise is called a co-proof method - a method that provides the studio of fecal masses under a microscope to identify parasitic eggs, their larvae or fragments of sexual ripe worm.This analysis allows the identification of many varieties of worms, but is especially effective for worries that parasites in the intestines.Suitable for enteriobiosis diagnosis, ascariasis, ANKILOSTOMOSOSU, TRIHOCEphalosis and other types of infection.
To perform an analysis, you need to take a special sterile jar.Issued in the clinic, laboratories or purchased in the pharmacy.
Then everything is simple:
- It is necessary to fill 1/3 with feces feces.It must be done before 11.00.Check that third -parts are dirt, for example, blood, drops of other secretions do not fall into the jar, as it will negatively display the reliability of results.
- Lid filled with capacity must be tightly closed.It is signed and then packed in a disposable package.
- It is best if the material can be transferred to the analysis of 30-45 minutes after collection.It is allowed to store it in the refrigerator, but not for more than 8 hours.After this period, the material becomes inappropriate for analysis.
You can detect the results the day after the analysis.But in some laboratories it is done for up to 6 days.
The efficiency of this method is 30-35%, because for Helminths do not lay eggs every night.
Scraping (smearing)
The scraping is the most common analysis of the enterobio that allows you to identify the presence of pins that parasites in the intestines and passed a large number of eggs in the area around the anus, as well as in the area of the perineum every night.
Since children have especially suffered from enterobiosis, a child who visits kindergarten, school, should regularly scrape twice a year.Adults must also perform an analysis when the first signs of parasites occur: itching in the anus, bad sleep, deterioration of appetite, weight loss, irritability.
Analysis procedure:
- The scraping takes a special spatula available in the pharmacy, or with ordinary cotton wool, which previously moistened the physiological solution or hot water.They remove spoilage from the area around the anus, as well as the perineum.Another way is to fasten the sticky tape (tape) to the area around the anus.Gently removed, he has to paste him on the surface of pure and dry glass.
- The procedure must be performed in the morning, immediately after waking up.You can't go to the toilet before and rinse.You can smear in a clinic or at home.
- The rod or spatula, on which the surface is on the survey biomass, is packed in sterile dry jars, package.Packaging should be sealed.
- It is necessary to submit the material for research laboratories on the day of taking the smear, it is better immediately.If necessary, a maximum of 5 hours 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 typical of the enterobiosis are preserved, the procedure must be forwarded next day or every other day.Maximum efficiency guarantees 3-4 a negative result of analysis performed in a row.
Blood test
The blood test shows the presence of the parasite, because as a result of their lives, they affect the internal organs, mucosa, release a large number of toxins.This causes changes in blood composition.When Helminth appears, the immune system starts producing antibodies (immunoglobulins).Can be identified as a result of the study.
The main thing is to compose the competent decoding of the results, which can only do an experienced specialist.
Blood test for parasites determines all their varieties - ascaride, lamblia, flat worms, two -water, trichinella, trematodes.Most of them are parasitic in the internal bodies: in the liver, lungs, canals, not in the intestines, therefore, using other tests, will not work on identifying these types of parasites.
Analysis delivery procedure:
- In order to do the analysis, a vein blood is needed.It is enough to take 3-5 ml of materials from the vein of the elbow.The procedure is done on an empty stomach, preferably in the morning.
- Specialists study selected blood in the Laboratories for specific antibodies, which allows you to specify the Helminthiasis stage.
- Decrypt the results of the analysis.
Before donating blood, the patient must pass the preparation phase.It starts a week before diagnosis and involves a complete refusal for the use of antibiotics and other medicines, whose composition negatively affects the accuracy of the results.The day before the analysis, it is worth excluding greasy products, sweets, carbonated drinks and always alcohol from the diet.
Determination of herminthic invasion is also performed by a general blood test.This is quite informative, allows you to identify different types of worms, but the most efficient compared to Pinworms, as well as ascaris.
When decrypting the general analysis, the following indicators are taken into account:
- Hemoglobin - with worm impairment, decreases;
- Leukocytes - when helminthim are infected, their concentration increases.
The blood is taken from the vein for analysis.Before the proceedings, 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, Analysis of antibodies and immunoglobulin
This analysis is based on the immunological response of the body, the level of its protective reaction to the parasite invasion.
- Using ELISA results, you can determine the presence of hermimans in the body and their kind.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 to one or other type of parasite, determining their connection with foreign antigens (immunological response) and the enzyme body reaction.
- Antibodies against antigens indicate an infection.
- The blood test of the ELISA has precision, according to various experts, from 60% to 90% even at the low level of invasion.
- The advantage of the method, next to the high level of accuracy, is that the immuno function can be monitored by the dynamics of the disease with time.
Polymerase chain reaction (PCR analysis)
The PCR method is one of the most modern and more accurate for blood diagnostics for the presence of the body parasite.It consists of discovering the traces of DNA and RNA, which belong to parasitic life forms.
- The essence of the reaction of the polymerase is a blood treatment in such a way that it copies and propagate DNA, RNA foreign organisms on the concentration that enables them to determine.
Serological blood test
At the same time, the analysis is used as a source of information on blood serum.
- The immunogenic antibodies of parasites are being investigated.
- The analysis allows you to identify a large number of parasitic shapes, but does not allow you to specify the invasion phase.
- Like the IFA method, serological analysis is indirect to diagnosis.
- If the OPD values are large, it is advisable to pass the fecal analysis.
How and where to take tests for parasites
It is necessary to take tests for parasites when symptoms are typical of the hermintage invasion: digestive problems, asthenia, weight loss, dermatological disease.It is also necessary to undergo diagnostics for Helminthe in situations in which a person suffers from chronic disease for many years, but the treatment does not give the expected result.In many cases, it turned out that the disease does not cause physiological problems, but the result of the worm parasic.
Before you pass the process, you must get direction from a gastroenterologist, specialist in infectious diseases, proctologists, therapists, surgeons, dermatologists and pediatrics.With that direction, the person goes to the lab.After studying biomaterials, he receives a form of results, which indicates whether the cheering is revealed in the body.
If the results of the analysis confirmed the presence of worms, it is important to immediately contact a qualified doctor.It can be a specialist for infectious diseases or a therapist.When Helminthiasis is diagnosed in a child, the pediatrician will help.
To take tests that identify parasites should at least once a year.To undergo diagnostics, it is important to choose a good laboratory, whose experts guarantee the maximum accuracy of the results.
