Which tests should be taken for parasites

Information that 80-90% of people are infected with worms, many people come with the idea that you need to drink anthelmintic medicines for a preventive purpose.

The human body parasites different types of worms, special tests have been developed for their identification.The procedure of diagnostic procedure has a certain percentage of reliability and varies in behavioral features.

Blood tests for parasites

The vital activity of parasites in the body causes the abuse of vague etiology.They can be rash, flat, heartburn, vomiting, weakness, anemia, joint pain.To clarify the diagnosis, special tests must be performed for the parasites.

How to check for parasites in the human body

Classification of parasites in their appearance:

For representatives of some professions (for food enterprise personnel, children's institutions), analysis of worm eggs in the design of sanitary books is required.Children go through the same analysis after receiving gardens and a nursery or in a sports section.

• A classic study of worms living in the gastrointestinal tract is a feces analysis and a mucosal fragmentation from the rectum.
• But there are several options for more effective blood tests for parasites, as the method is intended.

Reasons for providing analysis for parasites

When infected with individual parasites, a person may not feel symptoms.But over time, the number of helminths increases, and the infection begins to manifest.It is necessary to do tests for parasites if there are such symptoms:

• abdominal pain of different localization, which can occur spontaneously or in palpation;
• itching in the anus that appears at night;
• joints of the joints and muscle;
• reduced and nausea appetite;
• Increased appetite with abundant saliva;
• intestinal dysbiosis;
• constipation or diarrhea;
• Change in the color of the feces;
• increased fatigue;
• dizziness;
• dimming of the skin;
• insomnia or sleep disturbances;
• nervousness;
• dermatitis;
• incontinence of urine;
• In women, abundant discharge from the vagina, menstrual cycle violation.

The nature of the symptoms depends on the type of parasites.Itching and burning in the anal region cause pinworms worms.Ascarides provoke severe allergic reactions as well as abdominal pain.Lambia, Echinococci and Bicondumure affect the liver.They are often the cause of obstruction of the biliary tract and cholestasis (biliary stagnation), inflammation of the gall bladder.Light 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 pain in the proper hypochondrium.

If some of the listed symptoms appear, it is necessary to go to the hospital in order to identify the parasites in the body in time.It is necessary to do regular preventive tests for children's parasites, people living or working with animals.If raw meat, sharp, slightly salty, layer 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 parasites.

Which tests for parasites exist

There are various reasons that cause the need to get a helminths analysis.

In this parameter, 3 types of tests are distinguished:

1. Preventive - necessary for timely detection of helminthiasis even in the absence of characteristic symptoms.They are performed at a person's personal initiative or medical examination.It is recommended to take such an analysis every year, especially for children.
2. Obstacles - are prescribed to minimize the risk of spreading helminthiasis between the population.This is a mandatory analysis that children pass before entering a kindergarten or school, food industry workers, service areas, medical staff to obtain a medical book.Barrier analysis is given once a year.
3. As described by a doctor, this type of helminths analysis is prescribed by a doctor in the presence of characteristic symptoms of helminthiasis: nausea, stomach disorders, anus itching, weight loss, abdominal pain, 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 described.Let us consider in detail the features of each.

With a sharp weight loss, you should think of the need to perform analysis for parasites

Calais analysis for worm eggs

Feca analysis for parasites, in another way, is called a Koprogram method that provides for the study of fecal masses under a microscope in order to identify parasite eggs, their larvae or sexually mature worm fragments.This analysis makes it possible to identify many types of worms, but is especially effective for worms that parasitize in the intestines.Suitable for the diagnosis of enterobiosis, ascariasis, ankylostomosis, trichocephalosis and other types of infection.

To perform an analysis, you need to get a special sterile jar.Is released at a clinic, laboratories or bought at a pharmacy.

Then everything is simple:

1. It is necessary to complete 1/3 with feces with feces.This should be done before 11:00.Make sure the third party impurities, for example, blood, points of other secretions do not fall into the jar, as this will negatively exhibit the reliability of the result.
2. The stuffed capacity lid must be tightly closed.Is signed, and then packaged in a package available.
3. It is best if the material can be transferred for analysis 30-45 minutes after collection.It is permissible to store it in the refrigerator, but no more than 8 hours.After this period, the material becomes inappropriate for analysis.

You can detect the results one day after the analysis.But in some laboratories it is up to 6 days.

The effectiveness of this method is 30-35%, as the poisons do not lay eggs every night.

Scrap (stain)

Scraping is the most common analysis of enterobiosis, which allows you to identify the presence of worms that parasitize in the intestine and laid a large number of eggs in the area around the anus as well as in the perineum area every night.

Since children often suffer from enterobiosis, a child visiting a kindergarten, a school, should take a scrap regularly twice a year.Adults should also do an analysis when the first signs of parasites appear: anus itching, poor sleep, deterioration of appetite, weight loss, irritability.

Analysis Procedure:

1. Scraping is obtained from a special spatula, which is available at the pharmacy, or with a common cotton wool, previously moistened in a salt or warm water.They remove a stain from the area around the anus as well as perineum.Another way is to attach an adhesive tape to the area around the anus.Gently removed, it should be glued to the surface of the clean, dry glass.
2. The procedure should be performed in the morning, immediately after you wake up.Before that, you can't go to the toilet and wash.You can get a stain in a clinic or at home.
3. A stick or a spatula, on the surface of which there is a research biomass, is filled in a sterile dry jar, pack.The packaging should be sealed.
4. It is necessary to submit the material to the laboratory for research on the day of receiving a stain, it is better immediately.If necessary, for a maximum of 5 hours, it can be stored in the refrigerator.

You can detect the results next day.

If the results of the first analysis were negative but the typical symptoms of enterobiosis are stored, the procedure should be passed again the next day or every other day.Maximum effectiveness guarantees 3-4 negative results of analyzes performed in a row.

Blood test

A blood test indicates the presence of parasites, because as a result of their lives, they affect the internal organs, the mucous membranes, emit a large number of toxins.This provokes changes in blood composition.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 results is performed, which can only be done by an experienced specialist.

A blood test for the parasites determines all their varieties - ascaride, lamblia, flat worms, two water, trichinella, trematoda.Most of them parasitize in the internal organs: in the liver, lungs, channels and not in the intestine, therefore, using other tests, will not work to identify these types of parasites.

Procedure of Submission of Analysis:

1. To do the analysis, venous blood is needed.It is enough to get 3-5 ml of material from the elbow vein.The procedure is performed on an empty stomach, preferably in the morning.
2. Specialists study the selected blood in the laboratory for specific antibodies, which allow you to determine the phase of helminthiasis.
3. Deciphering the results of the analysis.

Before donating blood, the patient must pass the preparation phase.It begins a week before the diagnosis and involves a complete refusal to use antibiotics and other medicines, 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 the diet.

Determination of helminthic occupation is also performed using a general blood test.It is very informative, allows you to identify different types of worms, but more effective in terms of worms as well as ascaris.

When deciphering general analysis, the following indicators consider:

• Hemoglobin - with worm damage, is reduced;
• Leukocytes - when infected with helminths, their concentration has increased.

For analysis, blood is taken from a vein.Before the procedure, it is important not to eat 8, but better than 12 hours.It is permissible to drink only water.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 response to the occupation of parasites.

• Using ELISA results, you can determine the presence of helminths in the body and their type.The accuracy of the study is much higher than the feces analysis.
• The method is based on the calculation of antibodies in the body in one or another type of parasites, the determination of their connection to foreign antigens (immune response) and the enzyme reaction of the body.
• Anti-antigens antibodies indicate an infection.
• A blood test from ELISA has accuracy, according to various experts, from 60% to 90% even to the low level of occupation.
• The advantage of the method, in addition to a high level of accuracy, is that an analysis of immuno function 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 accurate for diagnosing blood for the presence of parasites in the body.It consists of discovering traces of DNA and RNA, belonging to the parasitic forms of life.

• The essence of the polymerase reaction is to treat blood in such a way as to copy and spread DNA, RNA of foreign organisms in a concentration that allows them to determine.

Serological test

At the same time, the analysis is used as a source of information for blood serum.

• The immunogenic antibodies of the parasites are investigated.
• The analysis allows you to identify a large number of parasitic forms, but does not allow you to determine the occupation phase.
• 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.

As and where to do tests for parasites

It is necessary to do tests for parasites when typical symptoms of helminthic occupation appear: digestive problems, asthenia, weight loss, dermatological diseases.It is also necessary to undergo diagnostics for helminths in situations when a person suffers from a chronic illness for many years, but treatment does not give the expected result.In many cases, it turns out that the disease is provoked not by physiological problems, but by the consequence of worm parasitization.

Before going through the procedure, you should take a direction from a gastroenterologist, infectious disease specialist, proctologist, therapist, surgeon, dermatologist and pediatrician.In this regard, a person goes to the lab.After studying biomaterials, it gets a form of results, which indicates whether helminths are detected in the body.

If the results of the analysis confirmed the presence of worms, it is important to consult a qualified physician immediately.It can be a specialist or therapist of the infectious disease.When helminthiasis is diagnosed in a child, a pediatrician will help.

To obtain tests that identify parasites need at least once a year.To undergo diagnosis, it is important to choose a good laboratory whose specialists guarantee the maximum accuracy of the results.
