The idea that parasite infection is always accompanied by a characteristic clinical picture is wrong.Often, helminthic infestation occurs in the absence of alarming 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 system 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 prevent various complications when the body is affected by parasites.
Instructions for the test
In most cases, the infection of the body with parasites is accompanied by characteristic symptoms, which are quite difficult not to notice.However, in the initial stages of helminthic infestation, the clinical picture can be practically expressed.During this period, the presence of protozoa in the human body can only be determined by examining the parasites.
Among the main signs, the presence of which forces a person to undergo a test for parasites:
- Itching in the anal region, mainly at night, due to the laying of eggs by parasites.
- Digestive disorders expressed by the appearance of constipation, diarrhea, nausea, vomiting, heartburn.
- Fatigue, lethargy, weakness.
- Decreased immunity and body resistance, susceptibility to infectious and viral diseases.
- A general disorder, pale skin of the face and body, caused by a lack of useful micronutrients absorbed by parasites in the body.
- Lack of appetite or, conversely, excessive desire to eat.
- 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 a critical level.
Due to non-observance of basic personal hygiene rules, children in the younger age category are most susceptible to infection with parasites.However, parasites are also possible in adults.Getting infected with helminths is easier than many people imagine.
It is recommended to undergo tests at least once or twice a year to prevent complications and worsening of the condition.It is advisable to conduct the research in summer and autumn, because it is most common in this period.
A variety of effective methods
Modern practical medicine offers a wide variety of different tests for the presence of various parasites in adults and children, each of which has both clear advantages and disadvantages.In order to get a result as close as possible to the reliable one, it is advisable to take 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 frequently used methods are the following:
- stool analysis;
- hemolymph analysis;
- examination of a smear or a scrap.
In some cases, when a helminthic infestation is detected, a number of additional studies are required.Methods such as computer tomography, X-ray examination, and ultrasound examination can be used.The need is due to the fact that the activity of parasites often causes 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 detecting infection even in the early stages.Among the most widely used are enzyme-linked immunosorbent assays based on the detection of changes in the composition of hemolymphs induced by parasites.
Characteristic pathological changes in the blood occur as a result of the release of waste 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 infection or its absence.
The study of blood composition allows us to determine not only the presence of helminthic infestation, but also the types of parasites, their approximate amount and the degree of damage to the body.To get the most accurate results, it is recommended to follow certain rules regarding the blood donation procedure: it is better to collect the biomaterial on an empty stomach and only in the morning.
The reliability of the enzyme immunoassay is about 90% and allows identification of most of the known parasite species.In addition, one of the advantages of studying hemolymph is the ability to identify protozoan microorganisms that parasitize in other organs, such as the lungs or liver, rather than in the intestines.
Stool analysis
Often, traditional stool analysis is used to identify parasitic individuals in the human body.This method is valid only if at least 60-90 days have passed since the infection.In addition, the results of the examination of feces can reveal the presence of such parasites in the body that can parasitize only in the intestines, such as: nematodes, roundworms, 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 characteristics of the life cycle of parasitic individuals.
The analysis procedure consists in checking the feces for the presence of eggs, larvae and adults.If there were no parasite eggs in the biomaterial at the time of faeces collection, the test will be false negative even though the parasite infection is actual.In order to increase the probability of obtaining reliable results, it is recommended to follow a number of basic rules regarding the submission of biomaterial:
- Feces must be collected no later than 11 a.m. local time in the morning.
- The optimal mass of biomaterial is one third of a standard container for analysis, it 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 the presence of parasites and helminth eggs in the human body.
- It is advisable to submit the biomaterial to the laboratory no later than 30-40 minutes after its collection.In this case, the results will be as close to reliability as possible.If this is not possible, the biomaterial should be stored in a refrigerator.
To identify helminths, a stool test for any parasite should be performed along with other types of tests.Only examination with two or more methods will give reliable results.It is advisable to repeat the parasite analysis to detect helminthic infection at least once a year.In addition, if any eating disorders occur, they should be tested for parasites.
Scrap examination
The study of scraps from folds of anus tissue is one of the simplest and least reliable.It is possible to determine the presence of a parasite in an organism in this way only if the time of material collection coincides with the egg-laying period of parasitic individuals.However, this method is most often used to detect helminthic infection in young children.
During the procedure, biological material is collected from folds of tissue in the subject's anus using sterile adhesive tape or a cotton swab.To obtain the most reliable results, it is recommended to conduct the analysis at least three to four times.
Validity of the study
Obtaining reliable results when conducting any test for the presence of parasites requires first observing all the rules for collecting the test material.In addition, it is recommended to conduct at least two types of research simultaneously, through which it is possible to identify individuals that parasitize not only the intestines, but also other organs and tissues.
Less reliable ones include stool examination and anal itching.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 stool, and due to the elementary carelessness of the laboratory technician conducting the analysis.
How to check for helminths in the body to get the most accurate results?What are the most reliable tests for parasites?In order to immediately identify helminths and start the use of adequate therapy, it is necessary to follow a number of basic rules:
- The procedure for conducting any tests must be carried out in accordance with the established rules.
- It is advisable to repeat any type of research at least twice with an interval of several days.
- When symptoms such as itching and burning of the anus appear, it is advisable to collect biomaterial for stool analysis.
It should be remembered that adults should be examined once a year.Children, especially 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 the examination of biological materials for the presence of parasites in the body can be carried out in almost any medical institution, whether public or commercial.However, it should be noted that blood tests to identify parasites are not performed in every clinic, and simpler tests are performed almost everywhere.
How much would this type of research cost?The price of a blood test can vary significantly depending on the region and the type of medical facility.The cost of the stool test 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 apply therapy.Lack of adequate treatment can lead not only to intoxication, that is, poisoning of the body with waste products of helminths, but also to the development of inflammatory diseases of internal organs.
