To date, there is no reliable diagnosis method that would give a hundred percent results regarding the pathogens of disease and the degree of process activity.Compared to other methods, the most accurate blood test for parasites is.In this way, information on the presence of a certain microorganism can be obtained, regardless of the cycle of its vital activity from the formation of eggs and adult larvae.
Why is the exact diagnosis of Helmintha important?Almost all anti-comparative agents presented at 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 1 day to a few months.At the same time, Helminths affect the work of the whole human body.
Their development follows such physiological changes as:
- Desensitization (constant allergic reaction).
- Permanent lack of vitamins and different elements.In addition to the parasitic invasion, the structure of epithelial intestines is damaged, as a result, disturbs the absorption of different nutrients.
- Changes in a hormone background.
- Saint disorders (this is reflected in the usual blood test).Increasing vascular bandwidth.
- Development of chronic digestion pathology (liver and biliary tract disease, pancreas inflammation, intestines), endocrine (diabetes), bronchopulmonal (bronchial asthma) system.
- Deterioration of allergic diseases.
- Emotional disorders (chronic fatigue, irritability, availability, insomnia, constantly alarming, pathological hyperactivity).
- Exercise by severe course of diseases caused by viruses and infections due to immunodeficiency.
Confirmation of the diagnosis of a blood test from the veins on parasites is also recommended when specific symptoms of helmintis occur.Let us reside we most often.A possible peeling infection testifies it by itching in the anus area, it increases significantly in the evening and night.Its intensity depends on the power of invasion.Sometimes it is not limited to anus, but refers to external genitania.Constant combing can cause infectious complications.
Blazotal (TrihoceFale) invasion monitors the general mammal, pain in the right Iliac region, diarrhea is constantly replaced by constipation, sometimes blood is observed.Stronbyloidosis continues with constant fluctuations of temperature, rash on chest, buttocks, abdomen, lower back and hips, stench of diarrhea (up to 7 times a day).
Signs of trichinosis are symptoms of acute intoxication, facial swelling, strong muscle pain.It is dangerous to beat almost all internal organs and the central nervous system.The toxocarosis is characteristic and the nightly dry cough.Sometimes toxox character larvae enter the brain with blood flow.In this case, the patient may have convulsive seizures and other neurological symptoms.
Almost all parasites are characterized by a set of clinical characters consisting of:
- pain and rumming in the abdomen;
- Nausea, less often - vomiting;
- Breaches of chairs;
- bloating;
- allergic events.
The most common method is the diagnosis of the helminthiasis serological immunosbent blood test to detect parasites.The decoding of this study is based on the detection of certain antibodies, which are produced in response to antigens of foreign microorganism.
The advantage of immunoformal analysis (ELISA) is its versatility.Such a technique applies to the diagnosis of worms in adult and adults and the child.Treatment with different drugs does not have a significant effect on the results.The only thing that can affect antibodic production is the state of immunodeficiency.In addition, this blood test for parasites is comprehensive, ie several pathogens can identify at the same time
How to check parasites, which tests should take, preparation for research
How to check parasites, which tests can be given in the clinical and diagnostic center.Now offer a lot of packages for complex diagnostics, which include research on all common helminths and protozoac.Her behavior does not require special training.
But to get reliable results, doctors recommend not eating 8-10 hours before analysis, blood in the morning strictly on an empty stomach in the morning.In addition, they advise to refrain from greasy and sweet food, alcohol.Stress, intense physical effort should be avoided.If the drug use falls in the early weather, you must convey it for several hours and drink it after the analysis.
The blood fence is made of veins.1-3 ml is enough for the study.Then the sister asks to bend his hand to the elbow and stay in this position for 10-15 minutes.This is necessary to prevent bruising creation.The result will be ready in 3-5 days.
In the IFA medical literature, IFAs are described using specific terminology, which is simply incomprehensible for a person without proper education, which are simply interested in checking parasites, which tests should check.
In the terms of the laboratory, they take a special tablet with cells in which the antigen of a particular parasite passed.A small amount of blood serum is added there.It is then used using the device, photometry during which certain markers are evaluated."Classic" studio includes: Giardia, Toxoplasm, TrichoMonas, all pathogene helminthia (pinworms, ascarides, bathrooms, ehinococi, opistarchy, trichinella).
As a result of ELISE, three types of antibodies can be distinguished:
- IgM, detect in 2.5-4 weeks of infection;
- Iga, is produced from the first days of the disease and is determined until the cure;
- Igg, Revealed starting in 4 weeks of disease, the fall of the title occurs only after 1-1.5 months after recovery.
Conclusion on the presence of a parasitic infection is done on the basis of the relationship between these antibodies.Their absence indicates that there is no Helminthic invasion.The specificity and reliability of ELISA is about 90%.
The probability of false positive and false negative results occurs in different failures in the work of the immune system.Therefore, only the data of ELISA, but also clinical images are not taken during diagnosis.If necessary, the patient is sent for additional examinations.
Analyzes for parasites in adults and child
There are other ways to identify Helminthic invasion.
The presence of such a disease can be assumed by a general blood test.
They pay attention to such signs as long-term, which lasts several months, increasing the level of eosinophils (normal values fluctuate within 1-5%), and some types of helicoglobs (reduction of hemoglobin concentration).
The usual parasite analysis in the child is known to scrape to all enterobioz.
To do this, immediately after waking up, without leaving bed and without washing, buttocks need to push and fasten a piece of tape to an anal hole and skin around it.It is then glued to the item and 1.5 hours is credited with the laboratory.
But this study allows you to specify only one type of parasite.Absolutely not suitable for identifying LAMBIA and other protozoos.Calais analysis is more indicative.In this case, you can discover the larvae of ascaris and different worms, pathogenic helmintize, parasites in the intestines.But a negative result does not always mean a lack of illness.Therefore, for a reliable diagnosis, different tests for parasites in the child are needed.
The negative analysis of the feces may turn out if the worms have not yet achieved the final parts of the digestive system or have already been through the cycle of expansion.Some medications can also affect data.It is therefore recommended to repeat the study after a few days.
But the most reliable analysis of parasites in an adult person and a child diagnosis is a chain reaction of polymerase or abbreviated PCR.At the same time, experts determine the DNA pathogen in the patient's blood.It is clear that with this study method is probably the probability of false data negligible.The analysis will give the correct result even in the initial phases of the invasion.
Usually PCR is prescribed to confirm the diagnosis.The widespread use of this method with a preventive goal limits high costs.In adults, testimonies for parasite are problems with immunity, generally deterioration in well-being, temperature of unclear etiology, cough and other symptoms of Helminthize.However, it is recommended that you start diagnostics by regular fecal analysis, which can be submitted in any clinic.
Important!The treatment should begin only after the tests for parasites in adults, and the confirmation of Helminthic invasion was obtained.Drug taking in case of suspicion of parasitic infection can cause serious complications.
Medical recommendations vary in a relatively early diagnosis of such diseases in childhood.It is necessary to download scraping in enterobiosis and feces on an egg - twice a year.Such tests for parasites in the child are needed before the visit to the garden and school.And in no case should be forgotten about prevention, which comes down to the often hand washing that suit the treatment of food and quality drinking water.
