The idea that parasite infection is always accompanied by a characteristic clinical picture is wrong.Often, helminthic infection occurs in the absence of worrying symptoms.If the treatment is not carried out in time, it can lead to very disastrous consequences, including: intoxication of the body, diseases of the digestive tract and other internal organs.Parasite detection tests will help determine the presence of foreign organisms and choose the best treatment option.Systematic research is needed in 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 organism with parasites is accompanied by characteristic symptoms, which are quite difficult not to notice.But in the early stages of helminthic infection, 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 forces 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 disease, 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 desire for food.
- Weight reduction to critical levels.Usually this happens only if the parasites have long infected the body and the number of individuals is close to critical.
Due to non-observance of the basic rules of personal hygiene, children of the youngest category are more susceptible to infection with parasites.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 that tests be done at least once or twice a year.It is recommended that the study be carried out in summer and autumn, as the peak incidence occurs more often in this time 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 as reliable as possible, it is advisable to do several types of tests simultaneously.This approach will help identify parasites even in the early stages of infection.
Among the most effective and most used methods are the following:
- stool analysis;
- hemolymph analysis;
- examining a spot or itch.
In some cases, when a helminthic infection is detected, a number of 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 the activity of parasites 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 used is an enzyme-linked immunosorbent assay, which is based on the identification of changes in the hemolymph composition that are provoked by parasites.
The characteristic pathological changes in the blood are caused by the release of waste products from the parasites and the subsequent intoxication of the body.In response to such factors, the body's immune system begins to produce antibodies.It is their quantity that determines the degree of helminthic infection or its absence.
A blood composition study allows us to identify not only the presence of helminthic infection, but also the types of parasites, their approximate amounts and the degree of damage to the body.To get the most accurate results, it is recommended to follow some 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 it allows you to identify the largest number of known types of parasites.In addition, one of the advantages of the study of 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 the stool examination can only reveal the presence in the body of such types of parasites that can parasitize only in the intestines, these are: 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 a single study often gives false negative results, which is due to the specifics of the life cycle of parasitic individuals.
The analysis procedure includes examination of feces for the presence of eggs, larvae and adults.If at the time of stool collection there were no parasite eggs in the biomaterial, the test will be false negative, regardless of the actual presence of parasite infection.To increase the likelihood of obtaining reliable results, it is recommended to follow a number of basic rules regarding the presentation of biomaterial:
- Stool collection should be done in the morning, no later than 11:00 a.m. local time.
- The optimal amount of biomaterial is one third of the standard container for analysis, which can be purchased at any pharmacy, but less may be required.
- This test is performed when the patient's body and skin around the anus itches.This sign indicates that in addition to parasites, helminth eggs are also present in the human body.
- It is recommended that the biomaterial be delivered to the laboratory no later than 30–40 minutes after its collection.In this case, the results will be as reliable as possible.If this is not possible, the biomaterial should be stored in a refrigerator.
Fecal testing for any parasite should be performed in combination with other types of tests to identify helminths.Only examination with two or more methods will give reliable results.It is advisable to repeat the parasite analysis to detect helminthic infestation at least once a year.In addition, you should be tested for parasites if you develop any eating disorders.
Scraping examination
The study of itching from the tissue folds of the anus is one of the simplest and least reliable.Determining whether there is a parasite in the body in this way is possible only if the time of collecting the material coincides with the period of laying eggs in parasitic individuals.However, this method is more often used to detect helminthic infection in children of the youngest age category.
During the procedure, biological material is collected from tissue folds in the subject's anus using sterile adhesive tape or a cotton swab.To obtain the most reliable results, it is recommended to perform the analysis at least three to four times.
Credibility of the research
Obtaining reliable results when performing any test for the presence of parasites first requires compliance with all the rules regarding the collection of test material.Moreover, 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 the intestines, but also 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 false negative, both due to the absence of eggs and adults in the feces, and due to the elementary inattention of the laboratory technician who performs 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 immediately identify helminths and start using adequate therapy, it is necessary to follow a number of basic rules:
- The procedure for taking each test must be carried out in accordance with the established rules.
- It is recommended that any type of study be repeated 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, especially the younger age groups, are at risk, so the child should be checked at least once every three months.
The cost of the procedure
The procedure for examining biological materials for the presence of parasites in the body can be carried out in almost any medical, public and commercial institution.But it should be noted that blood tests to determine parasites are not done in every clinic, while simpler tests are performed almost everywhere.
How much can this type of research cost?The cost of a blood test can vary significantly depending on the region and type of medical facility.The cost of stool testing is slightly lower.
Periodic examination of biological materials is an important and necessary measure.Timely identification of parasitic individuals will eliminate intoxication of the body and immediately implement therapy.Lack of adequate treatment can lead not only to intoxication, that is, poisoning of the body with waste products of helminths, but also provoke the development of inflammatory diseases of internal organs.
