To date, there is no reliable diagnosis method that will produce one hundred percent of the pathogen of the disease and the level of process activity.Compared to other methods, blood tests for parasites are most accurate.Only in this way, can information be obtained about the presence of certain microorganisms, regardless of the cycle of the essential activity from the formation of eggs and larvae to adults.
Why is the exact diagnosis of important helminths?Almost all antiparasitic agents presented in the pharmaceutical market have a variety of activities related to different worms.
However, the duration of treatment varies, depending on the type of disease, it can be from 1 day to several months.At the same time, helminths affect the work of the whole human body.
Their developments are accompanied by physiological changes such as:
- Desensitization (persistent allergic reaction).
- Persistent vitamin deficiency and various elements.With parasite invasion, the structure of the intestinal cells is damaged, as a result, the absorption of various nutrients is disrupted.
- Changes in hormone background.
- Holy disorders (this is also reflected in normal blood tests).Increase vascular permeability.
- The development of chronic digestive pathology (liver and biliary disease, pancreatic inflammation, intestines), endocrine (diabetes), bronchopulmonary system (bronchial asthma).
- Increased allergic disease.
- Emotional disorders (chronic fatigue, irritation, pain, insomnia, constant concern, pathological hyperactivity).
- Exercise towards a disease that is difficult to virus and infection due to immunodeficiency.
Confirmation of diagnosis by blood tests from parasites is also recommended when specific symptoms of helminthiasis appear.Let us live in the most common.Possible infections with pinworms (enterobiosis) are evidenced by itching in the anus, increasing significantly in the evening and night.Its intensity depends on the power of intrusion.Sometimes it is not limited to the anus, but applies to the external genitals.Continuous brushing can cause infectious complications.
Blazothale invasion (trichocephales) is accompanied by general fatigue, increased fatigue, pain in the right iliac region, diarrhea -is constantly replaced by constipation, sometimes the blood of blood in the stool is observed.Strongyloidosis continues with constant temperature fluctuations, rash in the chest, buttocks, stomach, lower back and hips, diarrhea (up to 7 times a day).
Signs of trichinellosis are symptoms of acute intoxication, swelling of the face, severe muscle aches.It is dangerous to defeat almost all the internal organs and central nervous system.Toxocarosis is also characterized by night dry cough.Sometimes toxocar larvae enter the brain with blood flow.In this case, the patient may have arrogant seizures and other neurological symptoms.
Almost all parasites are characterized by a set of clinical signs, consisting of:
- pain and rush in the stomach;
- Nausea, less frequent - vomiting;
- impairment of impurities;
- bloated;
- Allergic manifestations.
Currently, the most common method of helminthiasis is a serological immunosorbent blood test to detect parasites.The decoding of this study is based on the detection of certain antibodies, which are produced in response to foreign microorganisms.
The advantage of immunoformal analysis (ELISA) is flexibility.Such techniques can be used for the diagnosis of worms in adults and children.Treatment with various drugs has no significant effect on the results.The only thing that can affect the production of antibodies is the immunodeficiency condition.In addition, this blood test for parasites is comprehensive, that is, some pathogens can be identified at the same time
How to check parasites, what tests to take, preparation for research
How to check parasites, what tests can be given in clinical and diagnostic centers.Now they offer many packages for complex diagnostics, including research on all the same helminths and protozoa.His behavior does not require special training.
But for reliable results, doctors recommend not eating 8-10 hours before analysis, blood in the morning tightly on an empty stomach in the morning.In addition, they are advised to refrain from fatty and sweet foods, alcohol.Stress, intensive physical energy should be avoided.If the use of the drug falls at the beginning of time, you need to move it for several hours and drink it after the analysis.
Blood fences are made of veins.To conduct the study, 1-3 ml is enough.The nurse then asked to bend their hands on the elbows and stay in this position for 10-15 minutes.This is necessary to prevent the formation of bruises.The result will be completed in 3-5 days.
In medical literature, the IFA methodology is described using certain terms, which cannot be understood by a person without proper education, who is only interested in examining parasites, what tests to take.
In laboratory conditions, they took special tablets with cells where certain parasite antigens were introduced.A small number of blood serum is added there.Then, using the device, the photometry is carried out, where certain markers are evaluated."Classic" studies include: Giardia, Toxoplasmes, Trichomonas, All Helminthiases pathogens (Pinworms, Ascarides, Toxocars, Echinococci, Opistarchy, Trichinella).
As a result of ELISA, three types of antibodies can be distinguished:
- Igm, detects at 2.5-4 weeks of infection;
- Agency, produced from the first days of the disease and determined until healing;
- Igg, found from 4 weeks of the disease, a decrease in titer occurs only 1-1.5 months after recovery.
Conclusions about the presence of parasitic infections are made based on the ratio of these antibodies.Their absence indicates that there is no helminthic invasion.It is about 90%.
The probability of positive and false negative results occurs in various failures in the operation of the immune system.Therefore, when making a diagnosis, not only ELISA data is taken into account, but also clinical picture.If necessary, the patient is sent for additional examinations.
Analysis for parasites in adults and children
There are other ways to identify helminthic aggression.
The presence of such a disease can be assumed by a general blood test.
They pay attention to signs such as long-term, which lasts for several months, an increase in eosinophil levels (normal values vary in 1-5%), with some possible types of helmints anemia (reducing hemoglobin concentration).
The general analysis of parasites in children is a known binding to all enterobiosis.
To do this, immediately after the resurrection, without getting out of the bed and without washing, it is necessary to push the back and attach a piece of tape to the opening of the anus and the surrounding skin.Then it is glued to the item and for 1.5 hours is associated with the laboratory.
But this study allows you to determine only one type of parasite.It is true -it is not appropriate to identify lambia and other protozoa.Calais analysis shows more.In this case, you can detect different ascaris larvae and worms, helminthiasis pathogens, parasites in the intestine.But negative results do not always mean lack of disease.Therefore, for reliable diagnosis, various tests for parasites in children are required.
Negative analysis of stools can change if the worm has not reached the last part of the digestive system or they have passed the circulation cycle.Some drugs can also affect data.Therefore, it is recommended to repeat the study after a few days.
But the most reliable parasitic analysis in adults and children is a diagnosis by the abbreviated polymerase or PCR chain reaction.At the same time, the specialist determines the pathogenic DNA in the patient's blood.It is clear that with the method of this study, the probability of fake data can be ignored.This analysis will provide the right results even in the early stages of invasion.
Usually PCR is set to confirm the diagnosis.Widespread use of this method with the goal of prevention of limiting high costs.In adults, the testimony for parasitic examinations is a problem with immunity, general deterioration in well -being, unclear etiological temperature, cough and other symptoms of helminthiasis.However, it is recommended that you start diagnostic with regular fecal analysis, which can be submitted anywhere in the clinic.
IMPORTANT!Treatment should begin only after testing for parasites in adults has been taken, and confirmation of helminthic invasion has been obtained.Taking drugs if suspected parasite infection can cause serious complications.
Medical proposals differ in the early diagnosis of the disease in the childhood.It should take scraping to enterobiosis and stools on eggs -read twice a year.Such tests for parasites in children are required before visiting the park and school.And it is unforgettable about prevention, which comes to wash your hands regularly with food treatment and drinking water quality.
