To date, there is no reliable method of diagnosis that would give a result of one hundred percent as regards the pathogens of the disease and the degree of process activities.Compared to other methods, a blood test for parasites is more accurate.Only in this way can information be obtained on the presence of a particular microorganism, regardless of the cycle of its vital activity from the formation of the egg and the larva to an adult.
Why is the exact diagnosis of Elmininti's exact diagnosis?Almost all the antiparasitic agents presented in the pharmaceutical market have a wide range of activities in relation to different groups of worms.
However, the treatment period differs, depending on the type of disease, can be from 1 day to several months.At the same time, the helminths influence the work of the whole human body.
Their development is accompanied by physiological changes such as:
- Desensitization (constant allergic reaction).
- Persistent lack of vitamins and various elements.With the parasitic invasion, the structure of the epithelial intestinal cells is damaged, consequently, the absorption of various nutrients is disturbed.
- Changes in hormonal background.
- Sacred ailments (this is also reflected in the usual blood test).Increase vascular permeability.
- The development of chronic digestive pathologies (trafficking and liver disease and biliary, inflammation of the pancreas, intestine), endocrine (diabetes), bronchopulmonary system (bronchial asthma).
- Exacerbation of allergic diseases.
- Emotional disorders (chronic fatigue, irritability, mood, insomnia, constant alarming, pathological hyperactivity).
- Exercise to the difficult course of diseases caused by viruses and infections due to immunodeficiency.
The confirmation of the diagnosis by a blood test from the vein on parasites is also recommended when specific symptoms of elmintiasis appear.Let's dwell on the most common.The possible Pinworms infection (entertainable) is highlighted by the itching in the anus area, increasing significantly in the evening and night.Its intensity depends on the power of invasion.Sometimes it is not limited to the anus, but applies to the external genitals.Constant hairstyle can cause infectious complications.
The invasion of the Blazothale (Trichocephales) is accompanied by a general malaise, increase in fatigue, pain in the right iliac region, the diarrhea is constantly replaced by constipation, sometimes a blood stone is noted in the stool.Forteloidosis proceeds with constant temperature fluctuations, skin rashes on the chest, buttocks, abdomen, lower part of the back and hips, diarrhea stinks (up to 7 times a day).
Tricinellosis signs are symptoms of acute intoxication, swelling of the face, severe muscle pain.It is dangerous to defeat almost all internal organs and the central nervous system.Toxocarosis is also characterized by night dry cough.Sometimes the toxocar larvae enters the brain with the bloodstream.In this case, the patient may have convulsive convulsions and other neurological symptoms.
Almost all parasites are characterized by a set of clinical signs, consisting of:
- Pain and rhombus in the abdomen;
- nausea, less often - vomiting;
- violations of the feces;
- flatulence;
- Allergic manifestations.
Currently, the most common method of Elmintiasis diagnosis is an examination of the serological immunosorbent blood for the detection of parasites.The decoding of this study is based on the detection of some antibodies, which are produced in response to the antigens of the foreign microorganism.
The advantage of immunoformal analysis (Elisa) is its versatility.This technique is applicable for the diagnosis of worms both in an adult and in a child.Treatment with various drugs does not have a significant effect on the results.The only thing that can influence the production of antibodies is the state of immunodeficiency.In addition, this blood test for parasites is complete, that is, several pathogens can be identified simultaneously
How to check parasites, which tests to do, preparation for research
How to check parasites, which tests can be provided in the clinical and diagnostic center.Now they offer many packages for a complex diagnostics, including research on all common and protozoa eliminates.His conduct does not require special training.
But to obtain reliable results, doctors recommend not to eat 8-10 hours before the analysis, the blood in the morning strictly on an empty stomach in the morning.In addition, it is recommended to refrain from fat and sweet food, alcohol.Stress, intensive physical effort should be avoided.If the use of drugs falls in advance, you need to transfer it for several hours and drink it after analysis.
Blood fence is made of vein.To conduct the study, 1-3 ml is sufficient.So the nurse asks to bend hand on the elbow and stay in this position for 10-15 minutes.This is necessary to prevent the formation of a bruise.The result will be ready in 3-5 days.
In medical literature, the IFA methodology is described using a specific terminology, which is simply incomprehensible for a person without an adequate education, which is simply interested in how to check the parasites, which tests do.
In the conditions of the laboratory, they take a special tablet with the cells in which an antigen of a certain parasite is pre -introser.A small amount of blood serum is added.Then, using the devices, photometry is performed, during which specific markers are evaluated.The "classic" study includes: Giardia, Toxoplasmes, Trichomonas, all pathogens of Elminties (Pinworms, Ascarides, Toxocar, Echinococci, Opistorchia, Trichinella).
As a result of Elisa, three types of antibodies can be distinguished:
- IGM, detect to 2.5-4 weeks of infection;
- Iga, is produced by the first days of the disease and is determined to the treatment;
- IgG, discovered starting from 4 weeks of illness, a decrease in titles occurs only after 1-1.5 months after recovery.
The conclusion on the presence of a parasitic infection is made on the basis of the relationship between these antibodies.Their absence indicates that there is no elmintic invasion.Elisa's specificity and reliability are about 90%.
The probability of false positive and false negative results occurs in various failures in the functioning of the immune system.Therefore, when making a diagnosis, not only Elisa's data are taken into consideration, but also a clinical picture.If necessary, the patient is sent for further exams.
Analysis for parasites in adults and children
There are other ways to identify the Elmintic invasion.
The presence of this disease can be taken by a general blood examination.
They pay attention to signs as in the long term, which lasts several months, an increase in the level of eosinophilic is possible (normal values float within 1-5%), with some types of helminth anemia (reducing the concentration of hemoglobin).
A common analysis of parasites in a child is a scraping known to all enterobious.
To do this, immediately after waking up, without getting out of bed and without washing, it is necessary to push the buttocks and fix a piece of tape to the anal opening and the skin around it.So it is glued to the object and for 1.5 hours it is attributed to the laboratory.
But this study allows you to determine only one type of parasite.It is absolutely not suitable for the identification of Lambia and other protozoa.Calais's analysis is more indicative.In this case, it is possible to detect Ascaris larvae and several worms, pathogens of elmintiasis, parasites in the intestine.But a negative result does not always mean the lack of a disease.Therefore, for a reliable diagnosis, various tests for parasites are required in a child.
A negative analysis of the stool may be if the worms have not yet reached the final parts of the digestive system or have already exceeded the propagation cycle.Some drugs can also influence data.Therefore, it is recommended to repeat the study after a few days.
But the most reliable analysis of parasites in an adult and a child is the diagnosis by chain reaction of the polymerase or abbreviated PCR.At the same time, experts determine the patient's pathogen in the patient's blood.It is clear that with this method of study, the probability of false data is negligible.The analysis will also give an accurate result in the initial phases of the invasion.
The PCR is usually prescribed to confirm the diagnosis.The widespread use of this method with a preventive objective limits the high cost.In adults, the testimonies for the examination on parasites are problems of immunity, general deterioration in well -being, unsleteured etiology temperature, coughs and other symptoms of elmintiasis.However, it is recommended to start diagnostics with a regular faecal analysis, which can be delivered to any clinic.
Important!Treatment should only start after tests for parasites in adults have been taken and confirmation of the Elmintic invasion was obtained.The intake of drugs in case of suspicion of a parasite infection can cause serious complications.
Medical recommendations differ in the relatively early diagnosis of these diseases during childhood.It is necessary to take a scraping to the entertaining and the feces on the egg Leder twice a year.These tests for parasites in a child are requested before visiting the garden and school.And in no case should not be forgotten of prevention, which is reduced to the frequent washing of the hands corresponding to the treatment of food and the quality of drinking water.
