The opinion that parasite infection is always accompanied by a characteristic clinical picture is erroneous.Often, helminthic infestation occurs in the absence of disturbing symptoms.If treatment is not carried out in a timely manner, 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 required 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, 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 may 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 get tested for parasites, are:
- Itching in the anal area, disturbing mainly at night, due to the fact that the parasites have laid eggs.
- Digestive disorders, expressed in the appearance of constipation, diarrhea, nausea, vomiting, heartburn.
- Fatigue, lethargy, weakness.
- Decreased immunity and body resistance, susceptibility to infectious and viral diseases.
- General malaise, pale skin of the face and body, which is caused by a lack of beneficial microelements in the body, which are absorbed by parasites.
- Lack of appetite or, on the contrary, excessive cravings for food.
- Weight reduction up to critical levels.Usually this only happens if the parasites have long infected the body and the number of individuals is close to critical.
Due to non-compliance with basic rules of personal hygiene, children of the younger age category are most susceptible to infection with parasites.But parasites in adults are also possible.It is much easier to become infected with helminths than many people imagine.
In order to avoid complications and deterioration of the condition, it is recommended to take tests at least once or twice a year.It is advisable to conduct the study in the summer and autumn periods, since it is during this period of time that the peak incidence most often occurs.
Variety of effective methods
Modern practical medicine offers a wide range of various tests for the presence of various parasites in adults and children, each of which has both clear advantages and disadvantages.To obtain a result that is as close to reliable as possible, it is advisable to take several types of tests simultaneously.This approach will help identify parasites even in the early stages of infection.
Among the most effective and frequently used methods are the following:
- stool analysis;
- hemolymph analysis;
- examination of a smear or scraping.
In some cases, when a helminthic infestation 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 in comparison with other methods, and allows you to detect infection even in the early stages.Among the most commonly used is an enzyme-linked immunosorbent assay, which is based on identifying changes in the composition of the hemolymph that are provoked by parasites.
Characteristic pathological changes in the blood are caused by the release of waste products by parasites and 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 infestation or the absence thereof.
A study of the blood composition allows us to identify not only the presence of helminthic infestation, but also the types of parasites, their approximate quantities, and the degree of damage to the body.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 enzyme immunoassay is about 90%, and allows you to identify the largest number of known species of parasites.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 liver.
Stool analysis
Most often, traditional stool analysis is used to identify parasitic individuals in the human body.This method is reliable only 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, 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 examining stool 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 despite the actual presence of parasite infection.In order to increase the likelihood of obtaining reliable results, it is recommended to follow a number of basic rules regarding the submission of biomaterial:
- Stool collection should be carried out in the morning, no later than 11 a.m. local time.
- The optimal mass 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 advisable to submit the biomaterial to the laboratory no later than 30–40 minutes from the moment of its collection.In this case, the results will be as close to reliable as possible.If this is not possible, the biomaterial should be stored refrigerated.
Fecal testing for any parasites should be carried out in combination with other types of tests to identify helminths.Only examination through two or more methods will provide reliable results.It is advisable to repeat the parasitic analysis to detect helminthic infestation at least once a year.In addition, you should be tested for parasites if any eating disorders occur.
Scraping examination
The study of scraping from the folds of tissue of the anus is one of the simplest and least reliable.Determining whether there is a parasite in the body in this way is only possible if the time of collecting the material coincided with the period of egg laying in the parasitic individuals.However, this method is most often used to detect helminthic infestation in children of the younger age category.
During the procedure, biological material is collected from the folds of tissue in the anus of the subject using sterile adhesive tape or a cotton swab.To obtain the most reliable results, it is recommended to carry out the analysis 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 the test material.In addition, it is recommended to simultaneously conduct 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 assistant who conducts the analysis.
How to check for the presence of helminths in the body in order to get the most accurate results?What tests for parasites are the most reliable?In order to promptly identify helminths and begin the use of 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 advisable to repeat any type of study at least twice with an interval of several days.
- It is advisable 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 younger age groups, are at risk, so the child must be checked at least once every three months.
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 institution, both public and commercial.But it should be noted that blood tests to determine parasites are not carried out in every clinic, while simpler tests are carried out almost everywhere.
How much might this type of research cost?The cost of one 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 promptly apply therapy.The 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.
