The opinion that parasite infection is always accompanied by a characteristic clinical picture is wrong.Often, helminthic infestation occurs in the absence of disturbing symptoms.If the treatment is not carried out on time, it can lead to very disastrous consequences, including: intoxication of the body, diseases of the digestive tract and other internal organs.Parasite tests will help determine the presence of foreign organisms and choose the best treatment option.Systematic research is needed for both adults and children.
Timely tests will help to avoid various complications when the body is affected by parasites.
Indications for testing
In the vast majority of cases, the infection of the body with parasites is accompanied by characteristic symptoms, which are quite difficult not to notice.But in the early stages of helminthic infestation, the clinical picture can be practically unexpressed.The presence of protozoa in the human body during this period can only be determined by testing for parasites.
Among the main indications, the presence of which literally obliges a person to be tested for parasites, are:
- Itching in the anal area, disturbing mainly at night, due to the fact that parasites have laid eggs.
- Digestive disorders, expressed in the appearance of constipation, diarrhea, nausea, vomiting, heartburn.
- Fatigue, lethargy, weakness.
- Decreased immunity and resistance of the body, susceptibility to infectious and viral diseases.
- General weakness, pale skin of the face and body, which is caused by the lack of useful microelements in the body, which are absorbed by parasites.
- Lack of appetite or, on the contrary, excessive craving for food.
- Weight reduction to critical levels.Usually this happens only if the parasites have infected the body for a long time and the number of individuals is close to critical.
Due to non-observance of the basic rules of personal hygiene, children of the younger age category are the most susceptible to parasite infection.But parasites in adults are also possible.It is much easier to get infected with helminths than many people imagine.
In order to avoid complications and deterioration of the condition, it is recommended to be tested at least once or twice a year.It is recommended to conduct the research in the summer and autumn period, because the peak of incidence most often occurs in that period.
Variety of effective methods
Modern practical medicine offers a wide range of different tests for the presence of various parasites in adults and children, each of which has clear advantages and disadvantages.In order to get a result that is as close and reliable as possible, it is recommended to perform several types of tests at the same time.This approach will help identify parasites even in the early stages of infection.
Among the most effective and commonly used methods are the following:
- stool analysis;
- hemolymph analysis;
- examination of smears or scrapings.
In some cases, when a helminthic infestation is detected, numerous additional studies are required.Methods such as computed tomography, X-ray examination, ultrasound examination can be used.The need is due to the fact that parasite activity often leads to damage to internal organs and the development of cumulative diseases.
Blood test
A blood test for the presence of almost all types of parasites in the body is the most reliable compared to other methods and allows you to detect the infection even in the early stages.Among the most commonly used is the enzyme immunosorbent assay, which is based on the identification of changes in the hemolymph composition caused by parasites.
Characteristic pathological changes in the blood are caused by the release of waste substances by the parasite and subsequent intoxication of the organism.In response to such factors, the body's immune system begins to produce antibodies.Their quantity determines the degree of helminthic infestation or its absence.
Studying the composition of the blood allows us to identify not only the presence of helminthic infestation, but also the types of parasites, their approximate amounts and the degree of damage to the organism.In order to obtain the most accurate results, it is recommended to follow certain rules regarding the blood donation procedure: it is better to collect biomaterial on an empty stomach and only in the morning.
The reliability of the enzyme immunoassay is about 90% and allows you to identify the largest number of known parasite species.In addition, one of the advantages of studying hemolymph is the ability to identify protozoan microorganisms that parasitize not in the intestines, but in other organs, for example, the lungs or the liver.
Stool analysis
Most often, traditional stool analysis is used to identify parasitic individuals in the human body.This method is only reliable if at least 60 to 90 days have passed since the infection.In addition, the results of a stool examination can only reveal the presence in the body of such types of parasites that can parasitize only in the intestines, namely: nematodes, flukes, tapeworms.
As a rule, stool analysis for parasites is carried out at least two to three times with an interval of several days.This measure is necessary to obtain more reliable results.Conducting one study often gives false negative results, which is due to the specificity of the life cycle of parasitic individuals.
The analysis procedure includes examination of the stool for the presence of eggs, larvae and adults.If there were no parasite eggs in the biomaterial at the time of stool collection, the test will be false negative despite the actual presence of a parasitic infection.In order to increase the probability of obtaining reliable results, it is recommended to adhere to a number of basic rules regarding the submission of biomaterials:
- Stool collection should be done in the morning, no later than 11 a.m. local time.
- The optimal mass of biomaterial is one-third of a standard container for analysis, which can be purchased at any pharmacy, but less may be needed.
- This test is performed when the patient's body and the skin around the anus itch.This sign indicates that, in addition to parasites, helminth eggs are also present in the human body.
- It is recommended to submit the biomaterial to the laboratory no later than 30-40 minutes after taking it.In this case, the results will be as close to reliable as possible.If this is not possible, the biomaterial should be stored in the refrigerator.
Testing of feces for parasites should be carried out in combination with other types of tests to identify helminths.Only testing through two or more methods will give reliable results.It is recommended to repeat the parasite analysis to detect helminthic infestation at least once a year.Additionally, you should get tested for parasites if any eating disorders occur.
Scraping test
The study of scraping from folds of anal tissue is one of the simplest and least reliable.Determining whether there are parasites in the body in this way is possible only if the time of collecting the material coincided with the egg-laying period of parasitic individuals.However, this method is most often used to detect helminthic infestation in children of a younger age category.
During the procedure, biological material is collected from the folds of tissue in the anus of the subject with a sterile adhesive tape or cotton swab.To obtain the most reliable results, it is recommended that the analysis be performed at least three to four times.
Reliability of research
Obtaining reliable results when conducting any tests for the presence of parasites initially requires compliance with all rules regarding the collection of test materials.In addition, it is recommended to simultaneously carry out at least two types of research, through which it is possible to identify individuals that parasitize not only in the intestines, but also in other organs and tissues.
Less effective in terms of reliability include stool examination and anal scraping.This is due to the fact that the results of such tests can be falsely negative, both due to the absence of eggs and adults in the feces, and due to the elementary carelessness of the laboratory assistant conducting the analysis.
How to check the presence of helminths in the body in order to get the most accurate results?Which parasite tests are the most reliable?In order to timely identify helminths and start applying adequate therapy, it is necessary to follow a number of basic rules:
- The procedure for taking any tests should be carried out in accordance with the prescribed rules.
- It is recommended to repeat any type of study at least twice with an interval of several days.
- It is recommended to collect biomaterial for stool analysis when symptoms such as itching and burning of the anus appear
It should be remembered that an adult should be examined once a year.Children are at risk, especially younger age groups, so the child must be checked at least once every three months.
Cost of the procedure
The procedure for testing biological material for the presence of parasites in the body can be carried out in almost any health institution, both public and commercial.But it should be noted that blood tests to determine parasites are not done in every clinic, while simpler tests are carried out almost everywhere.
How much might this type of research cost?The price of a blood test can vary significantly depending on the region and type of medical facility.The price of chair testing is slightly lower.
Periodic examination of biological material is an important and necessary measure.Timely identification of parasitic individuals will eliminate intoxication of the body and apply therapy in a timely manner.Lack of adequate treatment can lead not only to intoxication, i.e. poisoning of the body with waste products of helminths, but also to the development of inflammatory diseases of internal organs.
