The opinion that parasitic infections are always accompanied by a characteristic clinical picture is wrong.Often, helminthic attacks occur without disturbing symptoms.If treatment is not carried out on time, it can lead to very bad consequences, including: intoxication, 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 for adults and children.
Timely tests will help to avoid 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.But in the early stages of helminthic attack, the clinical picture may be barely expressed.The presence of protozoa in the human body during this period can only be determined by testing for parasites.
Among the main signs, the presence of which literally obliges a person to be tested for parasites, are:
- Itching in the anal area, disturbing especially at night, due to the fact that the parasite has laid eggs.
- Digestive disorders, expressed in the form of constipation, diarrhea, nausea, vomiting, heartburn.
- Fatigue, lethargy, weakness.
- Decreased immunity and body resistance, susceptible to infectious diseases and viruses.
- General lethargy, pale skin of the face and body, which is caused by the lack of beneficial microelements in the body, which are absorbed by parasites.
- Lack of appetite or, conversely, an excessive desire for food.
- Weight loss up to a critical level.Usually this only happens if the parasite has been infecting the body for a long time and the number of individuals is close to critical.
Due to non-compliance with the basic rules of personal hygiene, children in the younger age category are most susceptible to parasitic infections.But parasites in adults are also possible.It is easier to get infected with helminths than many people imagine.
To avoid complications and deterioration of the condition, it is recommended to take the test at least once or twice a year.It is advisable to conduct the study in summer and autumn, as this is when peak events occur most often.
Various effective methods
Modern practical medicine offers various types of tests for the presence of various parasites in adults and children, each of which has clear advantages and disadvantages.To get almost reliable results, 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 as follows:
- stool analysis;
- hemolymph analysis;
- smear or scraping inspection.
In some cases, when a helminthic attack is detected, some 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 at an early stage.Among the most commonly used are enzyme-linked immunosorbent assays, which are based on identifying changes in hemolymph composition provoked by parasites.
Characteristic pathological changes in the blood caused by the release of waste products by the parasite and the subsequent intoxication of the body.In response to these factors, the body's immune system begins to produce antibodies.It is their quantity that determines the degree of helminthic attack or its absence.
The study of blood composition allows us to identify not only the presence of helminthic attacks, but also the type of parasite, its approximate quantity, 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 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 are not parasites in the intestine, but in other organs, for example, lungs or liver.
Stool analysis
Often, traditional stool analysis is used to identify individual parasites 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 the stool examination can only reveal the presence in the body of the types of parasites that can be parasites 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 step is necessary to get more reliable results.Conducting a study often gives false negative results, which is caused by the specifics of the life cycle of individual parasites.
Analytical procedures include examining feces for the presence of eggs, larvae, and adults.If at the time of stool collection there are no parasite eggs in the biomaterial, the test will be false negative even if there is an actual parasite infection.To increase the chances of obtaining reliable results, it is recommended to follow some basic rules regarding the submission of biomaterials:
- Faeces collection should be carried out in the morning, no later than 11 am local time.
- The optimal mass of biomaterial is one third of the standard container for analysis, which can be purchased at any pharmacy, but may be less needed.
- This test is performed when the patient's body and the 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 almost reliable.If this is not possible, the biomaterial should be stored in a refrigerator.
A stool test for any parasite should be carried out in combination with other types of tests to identify helminths.Only examination by two or more methods will give reliable results.It is advisable to repeat the parasite analysis to detect helminthic attacks at least once a year.In addition, you should be tested for parasites if any eating disorders occur.
Scratch exam
The study of scraping from the folds of anal tissue is one of the simplest and least reliable.Determining whether there are parasites in the body in this way is only possible if the time of collecting the material coincides with the period of laying eggs in the individual parasite.However, this method is most often used to detect helminthic attacks in children in the younger age category.
During the procedure, biological material is collected from tissue folds in the subject's anus using sterile adhesive tape or cotton swabs.To get the most reliable results, it is recommended to run the analysis at least three to four times.
Reliability of research
Obtaining reliable results when conducting any test for the presence of parasites initially requires compliance with all the rules regarding the collection of test material.In addition, it is recommended to carry out at least two types of research simultaneously, where 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 rectal 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 basic carelessness of the laboratory assistant who conducts the analysis.
How to check the presence of helminths in the body to get the most accurate results?What is the most reliable test for parasites?To identify helminths immediately and start the use of adequate therapy, it is necessary to follow some basic rules:
- The procedure for taking any test must be carried out in accordance with the established 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.
Keep in mind that adults should be checked once a year.Children, especially the younger age group, are at risk, so the child must be examined at least once every three months.
The cost of the procedure
The procedure to check biological material 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 does this type of research cost?The cost of a blood test can vary depending on the area and type of medical facility.The cost of a stool test is slightly lower.
Periodic inspection of biological material is an important and necessary step.Timely identification of individual parasites will eliminate body intoxication and immediately use therapy.Lack of adequate treatment can lead not only to intoxication, that is, poisoning of the body with waste products of helminths, but also trigger the development of inflammatory diseases of internal organs.
