The opinion that parasitic infection is always accompanied by a characteristic clinical picture is erroneous.Often, helminth 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 testing will help determine the presence of foreign organisms and choose the best treatment option.Systematic research is required for both adults and children.
Timely testing will help avoid various complications when the body is affected by parasites.
Indications for the test
In the vast majority of cases, infection of the body with parasites is accompanied by characteristic symptoms that are quite difficult not to notice.But in the early stages of helminth infestation the clinical picture can remain practically unexpressed.The presence of protozoa in the human body during this period can only be determined by parasite testing.
Among the main indications, the presence of which literally forces a person to be tested for parasites, are:
- Itching in the anal area, bothersome mainly at night, because the 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 discomfort, pale skin on the face and body, which is due to the lack of beneficial microelements in the body, which are absorbed by parasites.
- Lack of appetite or, conversely, excessive food cravings.
- Weight reduction to critical levels.Usually this only happens if the parasites have infected the body for a long time and the number of individuals is almost critical.
Due to non-compliance with basic rules of personal hygiene, children of the youngest age category are most susceptible to parasite infection.But parasites in adults are also possible.It is much easier to become infected with helminths than many people imagine.
To avoid complications and deterioration of the condition, it is recommended to perform tests at least once or twice a year.It is advisable to carry out the study in the summer and autumn periods, since it is during this period when the peak incidence occurs most frequently.
Variety of effective methods.
Modern practical medicine offers a wide range of diverse tests to detect the presence of various parasites in adults and children, each of which has clear advantages and disadvantages.To obtain the most reliable result possible, it is advisable to perform 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 series of additional studies are required.Methods such as CT scan, X-ray examination and 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 makes it possible to detect infections even in the early stages.Among the most used is the enzyme-linked immunosorbent assay, which is based on identifying changes in the composition of hemolymph caused by parasites.
Characteristic pathological changes in the blood are caused by the release of waste products by 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 infestation or the absence of it.
A study of the composition of the blood allows us to identify not only the presence of helminthic infestations, 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 the biomaterial on an empty stomach and only in the morning.
The reliability of the enzyme immunoassay is approximately 90% and allows the identification of 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 liver.
stool analysis
Most often, traditional fecal 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 infection.In addition, the results of a stool examination can only reveal the presence in the body of types of parasites that can only parasitize in the intestines, these are: nematodes, trematodes and tapeworms.
As a rule, analysis of feces for parasites is carried out at least two or 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 specific characteristics of the life cycle of parasitic individuals.
The testing procedure includes examining the feces for the presence of eggs, larvae and adults.If at the time of fecal collection there were no parasite eggs in the biomaterial, the test will give a false negative despite the actual presence of parasitic infection.To increase the likelihood of obtaining reliable results, it is recommended to follow a number of basic rules regarding the presentation of biomaterial:
- Collection of feces should be carried out in the morning, no later than 11 a.m.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 needed.
- This test is done when your body and skin around your anus itch.This sign indicates that, in addition to parasites, there are also helminth eggs in the human body.
- It is advisable to send the biomaterial to the laboratory no later than 30 to 40 minutes from the time of its collection.In this case, the results will be as reliable as possible.If this is not possible, the biomaterial should be stored refrigerated.
Fecal testing for parasites should be done in combination with other types of testing to identify helminths.Only examination by two or more methods will provide reliable results.It is advisable to repeat the parasite analysis to detect helminthic infestation at least once a year.Additionally, if an eating disorder occurs, you should be tested for parasites.
scraping examination
The study of scraping the folds of the anus tissue is one of the simplest and least reliable.Determining in this way whether there is a parasite in the body is only possible if the time of collection of the material coincided with the period of egg laying in parasitic individuals.However, this method is most commonly used to detect helminthic infestations in younger 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 perform the analysis at least three or four times.
Research reliability.
To obtain reliable results when carrying out any tests for the presence of parasites, initially compliance with all rules related to the collection of test material is required.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 the intestines, but also other organs and tissues.
Less effective in terms of reliability include stool examination and anal scraping.This is because the results of these tests can be false negatives, both due to the absence of eggs and adults in the feces, and due to the basic lack of attention of the laboratory assistant who performs the analysis.
How to check the presence of helminths in the body to obtain the most accurate results?Which parasite tests are the most reliable?To quickly identify helminths and start using appropriate therapy, it is necessary to follow a number of basic rules:
- The procedure for conducting any test must 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 fecal analysis when symptoms such as itching and burning in 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 should be checked at least once every three months.
Cost of the procedure
The procedure for examining biological materials for parasites in the body can be performed in almost any medical institution, both public and commercial.But it should be noted that not all clinics carry out blood tests for parasites, while simpler tests are carried out almost everywhere.
How much could 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 less.
Periodic examination of biological materials is an important and necessary measure.Timely identification of parasitic individuals will eliminate intoxication from the body and apply therapy in a timely manner.Lack of adequate treatment can provoke not only intoxication, that is, poisoning of the body with waste products of helminths, but also provoke the development of inflammatory diseases of internal organs.
