What tests should be performed on parasites

There are 80-90% of people who are infected with worms and many think about you need to drink antiworming medicine for preventive purposes.

The human body parasitizes different types of worms and special tests are developed for its identification.Each diagnostic procedure has a certain percentage of reliability and behavioral characteristics vary.

Blood tests for parasites

Important activities of parasites in the body can lead to unclear causes.It can be rash, flatulence, heartburn, nausea, weakness, anemia, joint pain.To clarify the diagnosis, special tests should be performed on the parasite.

How to check parasites in the human body

Classification of parasites in appearance:

For representatives of certain occupations (for staff of catering companies, children's institutions), the design of hygiene books requires analysis of worm eggs.Children are admitted to kindergarten, nursery or sports departments through the same analysis.

• A classic study of worms living in the gastrointestinal tract is the analysis of feces and the mucosal scratching of the rectum.
• However, as expected and according to the method, there are several options for more effective blood tests of the parasite.

Provide reasons for parasite analysis

When a single parasite is infected, a person may not experience any symptoms.But as time goes by, the number of worms increases and the infection begins to show itself.If this symptom is present, it is necessary to test the parasite:

• Abdominal pain with different locations can occur spontaneously or palpably;
• Anal itching that occurs at night;
• joint and muscle pain;
• Loss of appetite and nausea;
• Increased appetite and abundant saliva;
• Intestinal malnutrition;
• Constipation or diarrhea;
• Change the color of the feces;
• Increase fatigue;
• Dizziness;
• pale skin;
• Insomnia or sleep disorders;
• irritability;
• dermatitis;
• Urinary incontinence;
• In women, vaginal discharge is large and violates the menstrual cycle.

The nature of the symptoms depends on the type of parasite.Itching and burning in the anal area cause pinworms.Askarides can cause severe allergic reactions and squeeze abdominal pain.Lambia, echinococci and Bicondumure affect the liver.They are often the cause of biliary tract and cholestasis (bladder), inflammation of the gallbladder.Fat drops Fat is one of the main signs of liver and pancreatic pathology.The symptoms of parasitic effects on the liver and gallbladder are pain in the lower right corner.

If some listed symptoms appear, it is necessary to go to the hospital to identify the internal parasites in time.It is necessary to conduct regular preventive testing on children, people who live or work with animals.If you eat foods with raw, aerobic, slightly salty meat, lard or fish, the risk of infection is high.In this case, regular inspections must also be carried out to identify parasites.

What parasite tests exist

There are different reasons for the need for worm analysis.

In this parameter, there are three different test types:

1. Preventive - Even without characteristic symptoms, timely detection of helminthiasis is required.They are performed based on a person's personal initiative or medical examination.Such an analysis is recommended annually, especially for children.
2. Obstacles - Prescriptions are intended to minimize the risk of worm disease spreading in the population.This is a mandatory analysis that children pass before entering kindergarten or school, food industry workers, service areas, medical staff to obtain medical books.Barrier analysis is provided annually.
3. As the doctor prescribes, this type of worm analysis is prescribed by a doctor, under the symptom characteristics of existing helminthosis: nausea, stomach disease, anal itching, weight loss, abdominal pain, abdominal pain, increased fatigue, dizziness.With a single negative result, analysis must be performed again to ensure its reliability.

One or more tests are prescribed based on the condition and symptoms.Let's consider each feature in detail.

Calais analysis of worm eggs

The feces of parasites are analyzed in another way, called the coprogram-a method, which provides studies on the mass of feces under microscope to identify fragments of parasite eggs, their larvae or sexually mature worms.This analysis allows you to identify many worms, but is especially effective for worms that are parasitic in the gut.Suitable for the diagnosis of enterovirus, cariasis, celiacitis, tertiary meningitis and other types of infections.

To perform the analysis, you need to take a special sterile jar.It is purchased in a clinic, laboratory or pharmacy.

Then everything is very simple:

1. It is necessary to fill 1/3 of the feces with feces.This must be done before 11.00 hours.Make sure that other secretions that fall in third-party impurities (e.g. blood) do not fall into the jar, as this will have a negative view of the reliability of the results.
2. The cover that fills the capacity must be closed tightly.It is signed and then packaged in a single-use package.
3. It is best to transfer the material to 30-45 minutes after collection for analysis.It can be stored in the refrigerator, but not for more than 8 hours.After this period, the material becomes unsuitable for analysis.

You can find out the results the day after the analysis.But in some labs, up to 6 days can be completed.

This method has a 30-35% effectiveness because the worms do not lay eggs every night.

Scrape (smear)

Scraping is the most common analysis of gastrointestinal diseases, allowing you to identify the presence of parasitizing in the intestine and laying large amounts of eggs in the areas around the anus as well as in the perineal area every night.

Since children are especially often suffering from enterovirus, a child visiting a kindergarten (a school) needs to scratch twice a year.When the first sign of parasites appear, adults also need to analyze: anal itching, poor sleep, worsening appetite, weight loss, and irritability.

Analysis procedure:

1. Scraping is done by special scrapers available in the pharmacy or regular lint that was previously moistened in salt water or warm water.They remove smears from the area around the anus as well as the perineum.Another way is to attach the tape (tape) to the area around the anus.Remove gently and must be glued to a clean and dry glass surface.
2. The procedure must be performed in the morning immediately after waking up.Until then, you cannot go to the bathroom to wash it.You can apply smears at the clinic or at home.
3. A stick or spatula, on its surface, has a biomass for research, squeezed into a sterile dry jar.The packaging should be sealed.
4. It is better to deliver the material to the lab for research so that it can be done on the day of the smear.If necessary, it can be stored in the refrigerator at most.

You can find out the results the next day.

If the first analysis is negative but retains typical symptoms of gastrointestinal disease, the process must be passed again the next day or every other day.Maximum validity ensures 3-4 negative results for continuous analysis.

blood test

Blood tests show that parasites are present because their lives affect internal organs, mucosa, and release large amounts of toxins.This causes changes in blood composition.When the worm appears, the immune system begins to produce antibodies (immunoglobulins).They can be identified as studies.

The most important thing is to effectively decode the results, which can only be done by experienced experts.

Blood tests of the parasites determine all their breeds - ascaride, Lamblia, Flat Worms, two waters, Trichinella, Trematodes.Most of them are parasitic in internal organs: in the liver, lungs, ducts, not in the intestines, so using other tests it will ineffectively identify these types of parasites.

Analysis of conveying procedures:

1. For analysis, venous blood is required.It is enough to take 3-5 ml of material from the elbow vein.The process is performed on an empty stomach, preferably in the morning.
2. Experts have studied blood selected in a specific antibody lab, which allows you to determine the stage of worm disease.
3. Decipher the analysis results.

Before blood is donated, patients must pass the preparation phase.It begins a week before diagnosis and involves a complete refusal to use antibiotics and other drugs, whose composition may negatively affect the accuracy of the results.The day before the analysis, it was worth noting fat products, candy, carbonated drinks and drinking alcohol from the diet at all times.

The determination of worm invasion was also performed using general blood tests.It is very useful and allows you to identify different types of worms, but it has to do with Pinworms and Ascaris.

When conducting general analysis, the following indicators are considered:

• Hemoglobin - It is reduced due to worm damage;
• Leukocytes - When worms are infected, their concentration increases.

For analysis, blood is taken from the veins.Before the operation, it is important not to take 8, but to be better than 12 hours.Only drink water.It is necessary to stop taking antibiotics 5-7 days before the manipulation.

ELISA, antibody and immunosphere analysis

This analysis is based on the body's immune response, i.e. its level of protection against parasite invasion.

• Using the results of ELISA, you can determine the presence and type of worms in your body.The accuracy of the study is much higher than that of fecal analysis.
• The method determines their association with foreign antigens (immune responses) and human enzyme reactions based on calculations of in vivo antibodies of one or another type of parasites.
• Antigen antibodies indicate infection.
• According to different experts, ELISA's blood tests also range from 60% to 90%, even at low levels of invasion.
• The advantages of this method besides its high accuracy, immune function analysis can be monitored by the dynamics of the disease.

Polymerase chain reaction (PCR analysis)

PCR method is one of the most modern and accurate methods for blood diagnosis of parasites in the body.It includes detecting traces of DNA and RNA that belong to parasitic life forms.

• The essence of polymerase reaction is the way blood processes it is to replicate and reproduce DNA, and the concentration of foreign organisms RNA is so that they can be determined.

Serological blood test

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

• Immunogenic antibodies of parasites were studied.
• This analysis allows you to identify a large number of parasitic forms, but does not allow you to determine the invasion phase.
• Like the IFA method, serological analysis is an indirect diagnosis.
• If the value of OPD is high, it is recommended to use fecal analysis separately.

How to and where to use parasites

When typical symptoms of worm invasion occur, it is necessary to test the parasite: digestive problems, amblyopia, weight loss, dermatological disorders.Diagnosis in helminths must also be performed in the case of a person suffering from chronic disease for many years, but treatment does not give the expected results.In many cases, it turns out that the disease is not caused by physiological problems, but by the parasitic worms.

Before you pass this procedure, you need to get directions from gastroenterologists, infectious disease specialists, regulatory scientists, therapists, surgeons, dermatologists and pediatricians.With this direction, I went to the laboratory alone.After studying biomaterials, he received a result that showed whether worms were detected in the body.

If the results of the analysis confirm the presence of the worm, it is important to consult a qualified doctor immediately.It can be an infectious disease expert or a therapist.A pediatrician can help when helminthosis is diagnosed in children.

It takes at least one test to identify the parasite.To make a diagnosis, it is important to choose a good laboratory with its experts ensuring the highest accuracy of the results.
