The opinion that parasitic infection is always accompanied by a characteristic clinical picture is erroneous.Often, a helminthic infestation occurs in the absence of worrying 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 testing will help determine the presence of foreign organisms and help choose the best treatment option.Systematic research is needed for both adults and children.
Timely tests will help avoid various complications when the body is affected by parasites.
Indications for testing
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 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 tests for parasites.
Among the main indications, the presence of which literally obliges a person to be tested for parasites, are:
- Itching in the anal region, mainly disturbing at night, due to the fact that the parasites have laid eggs.
- 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.
- General malaise, pale skin of the face and body, caused by a lack of beneficial microelements in the body, absorbed by parasites.
- Lack of appetite or on the contrary excessive cravings for food.
- Weight reduction to critical levels.This usually happens only if the parasites have been infecting the body for a long time and the number of individuals is close to critical.
Due to non-compliance with basic rules of personal hygiene, the youngest children are most likely to be infected with parasites.But parasites in adults are also possible.It is much easier to become infected with helminths than many people imagine.
In order to avoid complications and deterioration of the condition, it is recommended to take tests at least once or twice a year.It is advisable to carry out the study during the summer and autumn periods, because 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 to detect the presence of various parasites in adults and children, each of which has both obvious advantages and disadvantages.To obtain the most reliable result possible, it is advisable to carry out 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:
- stool analysis;
- hemolymph analysis;
- examination of a smear or scraping.
In some cases, when a helminthic infestation is detected, a number of additional studies are required.Methods such as CT scan, X-ray examination, ultrasound can be used.This 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 to detect the presence of almost all types of parasites in the body is the most reliable compared to other methods and allows you to detect an infection even at an early stage.One of the most commonly used enzyme immunoassays is based on the identification of changes in hemolymph composition 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 immune system begins to produce antibodies.It is their quantity that determines the degree of helminthic infestation or its absence.
A study of blood composition allows us to identify not only the presence of helminthic infestation, but also the types of parasites, their approximate quantities and the degree of damage caused 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 can identify 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 the intestines, but 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 to 90 days have passed since infection.In addition, the results of a stool examination can only reveal the presence in the body of such types of parasites that can parasitize only in the intestines, namely: nematodes, flukes, tapeworms.
Typically, stool testing for parasites is done at least two to three times several days apart.This measurement is necessary to obtain more reliable results.Carrying out a single study often gives false negative results, due to the specifics of the life cycle of parasitic individuals.
The testing procedure includes examining the stool for the presence of eggs, larvae and adults.If at the time of stool collection there were no parasite eggs in the biomaterial, the test will be falsely negative despite the real presence of a parasitic infection.In order to increase the chances of obtaining reliable results, it is recommended to follow a number of basic rules regarding biomaterial submission:
- Stool collection should be done 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 needed.
- This test is performed when the patient's body and the skin around the anus are itchy.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 after collection.In this case, the results will be as reliable as possible.If this is not possible, the biomaterial should be stored in the refrigerator.
Fecal tests to detect any parasites should be done in combination with other types of tests 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, you should be tested for parasites if you have an eating disorder.
Scraping Exam
The study of scraping the folds of the tissues of the anus is one of the simplest and least reliable.Determining in this way whether there is a parasite in the body is possible only if the time of collecting the material coincided with the egg-laying period of the parasitic individuals.However, this method is most often used to detect helminthic infestation in children of the youngest age group.
During the procedure, biological material is collected from the tissue folds of the subject's anus using sterile tape or a cotton swab.To obtain the most reliable results, it is recommended to perform the analysis at least three to four times.
Research reliability
Obtaining reliable results when carrying out tests for the presence of parasites first requires compliance with all rules regarding the collection of test materials.In addition, it is recommended to simultaneously conduct at least two types of research to identify individuals that parasitize not only the intestines, but also other organs and tissues.
Stool examinations and anal scraping are less effective in terms of reliability.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 inattention of the laboratory worker carrying out the analysis.
How to check the presence of helminths in the body in order to obtain the most accurate results?Which parasite detection tests are the most reliable?In order to quickly identify helminths and start using adequate treatment, it is necessary to follow a number of basic rules:
- The procedure for taking the tests must be carried out in accordance with the prescribed rules.
- It is advisable to repeat any type of study at least twice several days apart.
- It is advisable to collect biomaterial for stool analysis when symptoms such as itching and burning of the anus appear
It should be remembered that an adult should be examined once a year.Children, especially younger age groups, are at risk, which is why they should be checked at least once every three months.
Cost of the procedure
The procedure for examining biological material for the presence of parasites in the body can be carried out in almost any medical, public and commercial institution.But it is worth noting that blood tests to determine parasites are not carried out in all clinics, while simpler tests are carried out almost everywhere.
How much could this type of research cost?The cost of a blood test can vary greatly depending on the region and type of medical facility.The cost of stool tests is slightly lower.
Periodic examination of biological material is an important and necessary measure.Timely identification of parasitic individuals will eliminate intoxication of the body and promptly apply treatment.The lack of adequate treatment can not only lead to intoxication, that is, poisoning of the body with helminth waste, but also provoke the development of inflammatory diseases of internal organs.
