The opinion that a parasitic infection is always accompanied by a characteristic clinical picture is wrong.Helminth infestation often occurs without any disturbing symptoms.If treatment is not carried out on 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 help determine the presence of foreign organisms and select the best treatment option.Systematic research is needed for both adults and children.
Timely tests help to avoid various complications when the body is attacked by parasites.
Notes on testing
In the vast majority of cases, an infection of the body with parasites is accompanied by characteristic symptoms that are difficult to miss.But in the early stages of helminthic infestation, the clinical picture can be practically unexpressed.The presence of protozoa in the human body during this period can only be determined by a parasite test.
The main indications, the presence of which literally obliges a person to be tested for parasites, include:
- Itching in the anal area, particularly annoying at night because the parasites have laid eggs.
- Digestive disorders manifested by constipation, diarrhea, nausea, vomiting and heartburn.
- Fatigue, lethargy, weakness.
- Decreased immunity and body resistance, susceptibility to infectious and viral diseases.
- General malaise, pale skin on the face and body, caused by a lack of useful microelements in the body, which are absorbed by parasites.
- Loss of appetite or, on the contrary, excessive desire for food.
- Weight reduction up to critical values.Usually this only happens when 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 younger age group 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 believe.
To avoid complications and worsening of the condition, it is recommended to carry out tests at least once or twice a year.It is advisable to carry out the study in the summer and autumn period, as the highest incidence occurs most often in this period.
Variety of effective methods
Modern practical medicine offers a wide range of various tests for detecting various parasites in adults and children, each of which has clear advantages and disadvantages.In order to obtain the most reliable result possible, it is recommended to carry out several types of tests at the same time.This approach helps to identify parasites in the early stages of infection.
The most effective and commonly used methods include:
- stool analysis;
- hemolymph analysis;
- Examination of a smear or scrape.
In some cases, when a helminth infestation is detected, a number of additional tests are required.Methods such as computer tomography, X-ray examination, ultrasound examination can be used.The need arises from 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 infections at an early stage.Among the most commonly used is the enzyme-linked immunosorbent assay, which is based on the identification of parasite-induced changes in the composition of hemolymph.
Characteristic pathological changes in the blood are caused by the release of waste products by parasites and subsequent poisoning of the body.In response to such factors, the body's immune system begins producing antibodies.Their quantity determines the degree of helminth infestation or its absence.
A study of the blood composition allows us to determine not only the presence of helminthic infestation, but also the type of parasites, their approximate quantity and the degree of damage to the body.In order to obtain the most accurate results, it is recommended to follow certain rules during 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 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 possibility of identifying protozoan microorganisms that parasitize not in the intestine, but in other organs, for example, the lungs or liver.
Stool analysis
Most often, traditional stool analysis is used to identify parasites 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 a stool examination can only reveal the presence in the body of those types of parasites that can only parasitize in the intestines, namely nematodes, leeches, 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 leads to false negative results, which is due to the peculiarities of the life cycle of parasitic individuals.
The analytical procedure includes examining the stool for the presence of eggs, larvae and adults.If there were no parasite eggs in the biomaterial at the time of stool collection, the test will be false negative despite the actual presence of a parasite infection.To increase the likelihood of obtaining reliable results, it is recommended to follow some basic rules for submitting biomaterial:
- Stool collection should take place 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 itch.This sign indicates that in addition to parasites, worm eggs are present in the human body.
- It is recommended to submit the biomaterial to the laboratory no later than 30-40 minutes after collection.In this case, the results will be as reliable as possible.If this is not possible, the biomaterial should be stored refrigerated.
Stool tests for parasites should be performed in combination with other types of tests to identify helminths.Only testing using two or more methods provides reliable results.It is advisable to repeat the parasite analysis to detect helminth infestation at least once a year.In addition, if you experience eating disorders, you should get tested for parasites.
Scratch examination
The study of scraping from the tissue folds of the anus is one of the simplest and least reliable.In this way, determining whether a parasite is present in the body is only possible if the time of collection of the material coincides with the time of laying of eggs by the parasitic individuals.However, this method is most often used to detect helminthic infestation in children of the younger age group.
During the procedure, biological material is collected from the tissue folds in the subject's anus using sterile tape or a cotton swab.In order to obtain the most reliable results, it is recommended to carry out the analysis at least three to four times.
Reliability of research
In order to obtain reliable results when conducting parasite tests, all rules for collecting test material must first be observed.In addition, it is recommended to simultaneously conduct at least two types of examinations that will help identify individuals who parasitize not only the intestines, but also other organs and tissues.
Less reliable in terms of reliability are stool examinations and anal scrapings.This is because 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 conducting the analysis.
How to check the presence of helminths in the body to get the most accurate results?Which parasite tests are most reliable?In order to detect helminths in a timely manner and initiate adequate therapy, some basic rules must be observed:
- The procedure for conducting 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 if symptoms such as itching and burning appear in the anus
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 examined at least every three months.
Costs 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.However, it should be noted that not every clinic carries out blood tests to determine parasites, while simpler tests are carried out almost everywhere.
How much might 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 a stool examination is slightly lower.
Regular examination of biological materials is an important and necessary measure.Timely identification of parasitic individuals avoids poisoning the body and initiates immediate 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 to provoke the development of inflammatory diseases of internal organs.
