Information that 80–90% of people are infected with insects, many people come with the idea that you need to drink antigentic drugs for a preventive purpose.
The human body performs various types of insects, special tests have been developed to identify them.Each clinical process contains a certain percentage of reliability and varies in the characteristics of conduct.
Blood test
The vital activity of the parasite in the body causes unhealthy of unclear etiology.It can cause skin rashes, flatulence, resentment, nausea, weakness, anemia, joint pain.To clarify the diagnosis, special tests should be performed for parasites.
How to check parasitic in human body
Classification of parasites in his presence:
Representatives of some businesses require analysis of insects eggs in the design of sanitary books (for food enterprises, children of children).Children pass the same analysis on admission in kindergarten and a nursery or a sports section.
- A classic study on the insects living in the gastrointestinal tract is an analysis of stool and a scraping of mucosa from the rectum.
- But there are many options for more effective blood tests for parasites, as is intended and according to the method.
Due to the distribution of analysis for parasites
When infected with individual parasites, a person may not feel any symptom.But over time, the number of helminth increases, and the infection itself begins to appear.If there are such symptoms then it is necessary to test for the parasite:
- The abdominal pain of separate localization, which may be spontaneously or coordination;
- Itching in the anus that appears at night;
- Addition and muscle pain;
- Low hunger and nausea;
- Increased appetite with abundant saliva;
- Intestinal dysbiosis;
- Constipation or diarrhea;
- Changes in the color of the stool;
- Increased fatigue;
- Dizziness;
- Skin palor;
- Insomnia or sleep disturbances;
- Irritability;
- Ringed inflammation;
- urinary incontinence;
- In women, abundant discharge from the vagina, violation of menstruation.
लक्षणों की प्रकृति परजीवी के प्रकार पर निर्भर करती है।गुदा क्षेत्र में खुजली और जलने से पिनवर्म होते हैं।Askarides provoke severe allergic reactions, as well as provoke abdominal pain.Lambia, Ichinocoki and bikondmore affect the liver.They are often the cause of biliary tract and cholestasis (bile stagnation), obstruction of gallbladder inflammation.Light stools with fat droplets are one of the main signs of pathology of the liver and pancreas.The symptom of parasitic effects on the liver and gall bladder is the correct hypochondri pain.
If many of the symptoms listed appear, in time it is necessary to go to the hospital to identify the parasites in the body.For children, it is necessary to conduct regular preventive tests for parasites, who live or work with animals.If raw, jerky, slightly salty meat, Lord or fish are consumed for food regularly, the risk of infection is very high.In this case, it is also necessary to check regularly to identify the parasites.
What tests exist for parasites
There are different reasons that cause the need to analyze for helminths.
On this parameter, 3 types of tests are distinguished:
- Preventive - In the absence of specific symptoms, it is also necessary to detect the time of helminthiasis.They are done in a person's personal initiative or a medical examination.It is recommended to do such analysis every year, especially for children.
- Barriers - are determined to reduce the risk of proliferation of helminthiasis among the population.It is a mandatory analysis that children pass to get a medical book before entering a kindergarten or school, food industry workers, service areas, medical staff.Barrier analysis is provided once a year.
- As prescribed by a doctor, this type of analysis for helminths is determined by a doctor in the presence of symptoms of helminthiasis: nausea, abdominal disorders, itching in the anus, weight loss, abdominal pain, increased fatigue, dizziness.With a single negative result, analysis must be taken again to ensure its reliability.
Depending on the condition and symptoms, one or more types of tests are determined.Let us consider the characteristics of each in detail.
With sharp loss of weight, you should think about the need to analyze for parasites
Callis analysis for worm eggs
Analysis of feces for parasites, in another way, it is called a Copgogram-A method that provides for the study of the fecal public under a microscope to identify parasitic eggs, their larvae or sexually mature pieces.This analysis makes it possible to identify many varieties of insects, but it is particularly effective for insects that are parasites in the intestines.Enterobiosis is suitable for diagnosis of infections and other types of infections.
To analyze, you need to take a special sterile jar.It is released in a clinic, laboratories or purchased in a pharmacy.
Then everything is simple:
- It is necessary to fill 1/3 with feces with stool.This should be done before 11.00 hours.Ensure that the third -disdaining impurities, for example, drops of blood, other secretions do not fall into the jar, as it will negatively display the reliability of the result.
- The lid of the filled capacity should be closed tightly.It is signed, and then packed in a disposable package.
- This is best if the material can be transferred for analysis after 30–45 minutes of the collection.It is allowed to store in the refrigerator, but now no more than 8 hours.After this period, the material becomes unsuitable for analysis.
You can find out the results after the analysis.But in some laboratories it is done for 6 days.
The effectiveness of this method is 30–35%, because helminth does not lay eggs every night.
Scrapping
Scraping is the most common analysis for antobiosis, which allows you to identify the presence of pinworms that are parasites in the intestines and laying a large number of eggs in the area around the anus, as well as in the perineum region every night.
Since children especially often suffer from antobiosis, a child who visits a kindergarten, a school, requires regular scraping twice a year.Adults also require an analysis when the first signs of parasites appear: itching, poor sleep, upper appetite, weight loss, irritability.
Analysis process:
- Scraping is taken by a special spatula, available in the pharmacy, or with a simple cotton wool, first moist in saline or warm water.They take out a spot from the area around the anus, as well as perineum.Another method is to attach a sticky tape (tape) to the area around the anus.Gently removed, it should be glued to the surface of the clean and dried glass.
- The process should be performed in the morning immediately after waking up.Before that, you cannot go to the toilet and wash.You can take a smear in a clinic or at home.
- A stick or a spatula, on which the surface is a biomass for research, is packed in a sterile dried jar, package.Packaging should be sealed.
- It is necessary to give material to the laboratory for research on the day of taking a smear, this is immediately better.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 earlier analysis were negative, but specific symptoms of antrobiosis are preserved, the process should be passed the next day or every other day.Maximum effectiveness guarantees 3-4 negative results of analysis made in a row.
Blood test
A blood test indicates the presence of a parasite, because as a result of their life, they affect the internal organs, leaving the mucous membrane, a large number of toxins.It stimulates changes in blood structure.When helminth appears, the immune system begins to produce antibodies (immunoglobulin).They can be identified as a result of study.
The main thing is that a competent decoding of results is done, which can only be done by an experienced specialist.
A blood test for parasites determines all their varieties - esceride, lambelia, flat insects, two -water, triachinela, trametods.Most of them do parasites in internal organs: the liver, lungs, in the ducts, and not in the intestines, therefore, using other tests, it will not work to identify this type of parasites.
Analysis distribution process:
- To analyze, venous blood is required.It is enough to take 3-5 mL content from the elbow vein.The process is performed on an empty stomach, preferably in the morning.
- Experts study the blood selected in the laboratory for specific antibodies, which allow you to determine the phase of helminthiasis.
- Reducing the results of analysis.
Before donating blood, the patient must pass the preparation stage.It begins a week before the diagnosis and includes complete refusal to use antibiotics and other drugs, which can negatively affect the accuracy of the composition result.A day before the analysis, it is always worth except alcohol from fatty products, sweets, carbonated drinks and diet.
Helminthic invasion is also determined using a common blood test.This is quite informative, allows you to identify different types of insects, but the most effective in relation to pinworms, as well as ascaris.
When reducing general analysis, the following indicators are taken into consideration:
- Hemoglobin - With insect damage, it decreases;
- Leukocytes - When infected with helminth, their concentration increases.
For analysis, blood is taken from a vein.Before the procedure, 8 is better than 12 hours, not food.Only water is allowed to drink.5-7 days before manipulation, it is necessary to stop antibiotics.
Analysis for Elisa, Antibody and Immunoglobulina
This analysis is based on the body's immune response, the level of its protective response to the parasitic invasion.
- Using the results of ELISA, you can determine the presence of helminth in the body and their types.The accuracy of the study is much higher than the analysis of the stool.
- The method is based on the calculation of antibodies in the body to determine their relationship with one or any other type of parasite, foreign antigen (immune response) and body enzyme reaction in the body.
- Anti-antibodge antibodies indicate an infection.
- A blood test is accuracy by Elisa, according to various experts, even at the low level of invasion from 60% to 90%.
- The benefit of the method, in addition to high level accuracy, is that an immun -function analysis can be monitored by the dynamics of the disease over time.
Polymerase series reaction
The PCR method is the most modern and accurate for the diagnosis of blood for the presence of parasites in the body.This involves detection of DNA and RNA marks related to parasitic life forms.
- The essence of polymerase response is blood treatment in such a way that copying and promoting DNA, allowing the RNA of foreign organisms to determine them for a concentration.
Serological blood test
At the same time, analysis is used as a source of blood serum information.
- Immunogenic antibodies of parasites are examined.
- The analysis allows you to identify a large number of parasitic forms, but does not allow you to determine the stage of the attack.
- Like the IFA method, the serological analysis for diagnosis is indirect.
- If the OPD values are high, it is advisable to pass the fecal analysis.
How and where to take tests for parasites
Testing for parasites is necessary when specific symptoms of helminthic invasion appear: digestive problems, esthenia, weight loss, skin diseases.In those conditions it is also necessary to undergo diagnosis for helminths where a person suffers from chronic disease for many years, but does not give the expected results.In many cases, it has been discovered that the disease is provoked not by physical problems, but as a result of parasitization of insects.
Before passing the process, you need to get a direction from a gastroenterologist, infectious pathologist, proctologist, physician, physician, surgeon, dermatologist and pediatrician.With this direction, a person goes to the laboratory.After the study of biometric, he achieves a form of results, which indicates whether helminth in the body is detected.
If the results of the analysis confirmed the presence of insects, it is important to consult a qualified doctor immediately.It can be an infectious pathologist or physician.When helminthiasis is diagnosed in a child, a pediatrician will help.
The parasites require at least once a year to take tests that identify the parasites.Passing through diagnosis, it is important to select a good laboratory, which guarantee the maximum accuracy of the results.
