The opinion that parasitic infection is always accompanied by a characteristic clinical picture is erroneous.Helminth infestation often 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 needed for both adults and children.
Timely tests will help to avoid various complications when the body is affected by parasites.
Instructions for the test
In the vast majority of cases, infection of the body with parasites is accompanied by characteristic symptoms, which are quite difficult to miss.But in the early stages of helminth infestation, the clinical picture can be 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 undergo an anti-parasitic test, there are:
- Itching in the anal area, especially annoying at night, due to the fact that the parasites have laid their eggs.
- Digestive disorders, expressed in the appearance of constipation, diarrhea, nausea, vomiting, heartburn.
- Tiredness, lethargy, weakness.
- Decreased immunity and resistance of the body, susceptibility to infectious and viral diseases.
- General malaise, pale skin of the face and body, caused by lack of beneficial microelements in the body, which are absorbed by parasites.
- Lack of appetite or, conversely, excessive desire for food.
- Weight reduction to critical levels.Usually this happens only if the parasites have infected the organism for a long time and the number of individuals is close to critical.
Due to non-compliance with basic rules of personal hygiene, children of younger age group are more susceptible to parasitic infections.But parasites in adults are also possible.It is much easier to get infected with helminths than many imagine.
To avoid complications and worsening of the condition, it is recommended to perform 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 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 clear advantages and disadvantages.To obtain the most reliable result possible, it is advisable to carry out multiple 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 scraping.
In some cases, when a helminth infestation is detected, several additional studies are necessary.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 tests
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 the infection even in the early stages.Among the most commonly used is the enzyme immunosorbent test, which is based on the identification of changes in the composition of the hemolymph caused 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 helminth infestation or its absence.
The study of blood composition allows you to identify not only the presence of helminth infestations, but also the types of parasites, their approximate quantity and the degree of damage to the organism.To obtain more accurate results, it is recommended to follow some 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 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 intestine, 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 only reliable if at least 60-90 days have passed since infection.In addition, the results of the stool examination can only reveal the presence in the body of such types of parasites that can parasitize only in the intestine, these are: roundworms, trematodes, tapeworms.
As a rule, stool analysis for parasites is performed at least two or three times with an interval of several days.This measurement is necessary to obtain more reliable results.Conducting a single study often provides false negative results, due to the specifics of the life cycle of parasitic individuals.
The testing procedure involves examining feces for the presence of eggs, larvae and adults.If at the time of stool collection there were no parasite eggs present in the biomaterial, the test will be false negative despite the actual presence of parasite infection.To increase the likelihood of obtaining reliable results, it is recommended to follow a number of basic rules regarding the presentation of the biomaterial:
- Stool collection must be carried out in the morning, no later than 11:00 local time.
- The optimal mass of biomaterial is one third of the standard container for the analysis, which can be purchased at any pharmacy, but a smaller amount may be needed.
- This test is performed when the patient's body and the skin around the anus itch.This sign indicates that in addition to parasites, helminth eggs are also present in the human body.
- It is recommended to deliver the biomaterial to the laboratory no later than 30–40 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 must be stored refrigerated.
Fecal tests for parasites should be done in combination with other types of tests to identify helminths.Only testing through two or more methods will provide reliable results.It is advisable to repeat the parasite analysis to detect helminth infestation at least once a year.Additionally, you should get tested for parasites if you experience an eating disorder.
Curettage examination
The study of scraping the folds of the tissue of the anus is one of the simplest and least reliable.Determining whether a parasite is present in the body in this way is possible only if the time of collection of the material coincides with the period of egg laying in parasitic individuals.However, this method is often used to detect helminth infestation in children of the younger age group.
During the procedure, biological material is collected from folds of tissue in the subject's anus using sterile tape or a cotton swab.To obtain more reliable results, it is recommended to carry out the analysis at least three or four times.
Reliability of the research
To obtain reliable results when testing for the presence of parasites it is necessary to initially comply with all the rules regarding the collection of test material.In addition, it is recommended to simultaneously conduct at least two types of research, through which it is possible to identify individuals parasitizing not only the intestine, but also other organs and tissues.
Less effective in terms of reliability are stool examination and anal curettage.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 carelessness of the laboratory assistant conducting the analysis.
How to check for helminths in the body to get the most accurate results?Which parasite tests are the most reliable?To timely 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 must be carried out in accordance with the prescribed rules.
- It is recommended to repeat any type of study at least twice with an interval of several days.
- It is recommended to collect biomaterial for stool 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 your child should 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 detect parasites are not performed in all clinics, while simpler tests are performed 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 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 timely 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 provoke the development of inflammatory diseases of internal organs.
