To date, there is no reliable method of diagnosis that would result in 100 percent results in the degree of disease and process activity.Compared to other methods, the blood test of parasites is the most accurate.In this way, information can be obtained about the presence of a particular microorganism, whether it contains a cycle of vital activity of eggs and larvae to an adult.
Why is it important to have accurate diagnosis of helmints?Almost all the antiparasit agents presented in the pharmaceutical markets have a wide range of activity in different groups of worms.
However, the treatment period may be different from 1 day to several months depending on the type of disease.At the same time, helmints affect the work of the entire human body.
Their development is accompanied by physiological changes such as:
- Desensitization (constant allergic reaction).
- A lasting lack of vitamins and various elements.In the case of parasite invasion, the structure of the epithelial intestinal cells is damaged, resulting in the absorption of various nutrients.
- Changes in the hormonal background.
- Sacred disorders (this is also reflected in the usual blood test).Increasing vascular permeability.
- The development of chronic digestive pathologies (liver and bile and bile and bile disease, inflammation of the pancreas, intestines), endocrine (diabetes), bronchopulmonary (bronchial asthma) system.
- Aggravation of allergic diseases.
- Emotional disorders (chronic fatigue, irritability, mood, insomnia, constant alarming, pathological hyperactivity).
- Practice the treatment of difficult diseases caused by viruses and immune deficiency infections.
Confirmation of the diagnosis by blood tests from the vein of parasites is also recommended if the specific symptoms of helminthiasis appear.Be the most common.A possible infection of Pinworms (enterobiosis) is confirmed by itching in the anus, which increases significantly in the evening and at night.Its intensity depends on the power of invasion.Occasionally, it is not limited to the anus, but applies to the external genitals.Constant combing can cause infectious complications.
The invasion of Blazothale (Trichocephales) is a general malaise, increased fatigue, pain in the better Iliac region, constantly replacing diarrhea with constipation, sometimes in the stool.Strongiloidosis flows with constant temperature fluctuations, rashes on the chest, buttocks, abdomen, lower back and hips, stench (7 times a day).
Signs of trichinellosis are the symptoms of acute intoxication, face swelling, and severe muscle pain.It is dangerous to overcome almost all internal organs and the central nervous system.Toxocarosis is also characterized by a night dry cough.Occasionally, toxocar 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 clinical symptoms consisting of:
- pain and buzz in the abdomen;
- nausea, less often - vomiting;
- stool violation;
- bloating;
- Allergic manifestations.
Currently, the most common method for diagnosing helminthiasis is a serological immunorbent blood test to detect parasites.The decoding of the study is based on the detection of certain antibodies, which are responded to antigens of foreign microorganism.
The advantage of immunoformal analysis (ELISA) is versatility.Such a technique can be used to diagnose worms in both adults and children.Treatment with various drugs does not affect the results.The only thing that can affect the production of antibodies is the state of immune deficiency.In addition, this parasites have a comprehensive blood test, ie several pathogens can be identified at the same time.
How to check parasites, what tests should be done, preparation for research
How to check parasites, what tests can be performed at the Clinical and Diagnostic Center.There are now many packages for complex diagnostics, which includes all the common Helmin and Protozoa research.His behavior does not require special training.
But to achieve reliable results, doctors recommend that you do not eat 8-10 hours before analysis, morning blood is strictly in an empty stomach.In addition, we recommend that they refrain from fatty and sweet foods, alcohol.Stress, intense physical effort should be avoided.If the use of medicines falls in the early times, you should pass and drink for several hours after analysis.
The blood fence is made of vein.1-3 ml is enough to perform the test.The nurse then asks you to bend her hand at the elbow and stay in this position for 10-15 minutes.This is necessary to prevent bruising from developing.The result is ready in 3-5 days.
In medical literature, IFA methodology is described by specific terminology, which is simply incomprehensible for a person without proper education who is simply interested in how to check parasites and what tests to take.
Under laboratory conditions, a special tablet is taken with cells in which a certain parasite antigen is pre -introduced.A small amount of blood serum is added.The tools are then performed by a photometry to determine specific grips.The "classic" study includes: giardia, toxoplasms, trichomonas, all pathogens (Pinworms, ascaride, toxocaros, echinococci, opistarchy, trichinella).
As a result of ELISA, three types of antibodies can be distinguished:
- Igm, detection of the infection of 2.5-4 weeks;
- YOKE, from the first days of the disease and is determined until healing;
- Igg, From the beginning of the disease from the beginning of the disease, the decrease in titers only occurs after 1-1.5 months after healing.
The conclusion of the presence of parasitic infection is concluded on the basis of the proportion of these antibodies.Their absence indicates that there is no helmintes invasion.ELISA has a peculiarity and reliability of about 90%.
The likelihood of false positive and false negative results occurs in various errors in the functioning of the immune system.Therefore, when the diagnosis is made, not only ELISA data is taken into account, but also a clinical picture.If necessary, the patient will be sent for further examinations.
Analysis of parasites of adults and children
There are other ways to identify the invasion of helmints.
The presence of such a disease is presumed to be a general blood test.
Such long-term signals that last for several months are taken into account, the increase in eosinophils (the normal values fluctuate within 1-5%), and certain types of halmint anemia (reducing the concentration of hemoglobin).
A general analysis of children's parasites is known to scrape all enterobiosis.
To do this, just after waking up, without getting out of bed and without washing, you need to push the buttocks and secure a piece of ribbon to the anal opening and the skin around it.It is then glued to the battery and attributed to the laboratory for 1.5 hours.
But this study allows you to define only one type of parasite.This is not at all suitable for identifying Lambia and other protozoa.Calais analysis is more indicative.In this case, you can detect the larvae of the ascaris and different worms, the helminthiasis pathogens, the gut parasite.But negative results do not always mean the lack of disease.Therefore, reliable diagnosis requires examination of parasites of various children.
The negative analysis of the stool may be revealed if the worms have not yet reached the final part of the digestive system or has already accepted the propagation cycle.Some drugs can also affect the data.Therefore, it is advisable to repeat the test in a few days.
But the most reliable analysis of parasites is adult and child diagnosis with a polymerase chain reaction or abbreviated PCR.However, experts determine the DNA of the pathogen in the patient's blood.Obviously, with this method of test, the probability of false data is negligible.The analysis also provides an accurate result in the initial stages of invasion.
PCR is usually prescribed to confirm the diagnosis.The widespread use of this method limits high costs for preventive purposes.In adults, the testimony of parasites testing is immunity problems, overall deterioration of the well, the temperature of non -clear etiology, other symptoms of cough and helmintasis.However, we recommend that you start diagnostics with a regular stool analysis that you can hand over to any clinic.
Important!Treatment should only be started after examining adult parasites and confirmed the Helmintus invasion.Taking medicines can cause serious complications in the event of a suspicion of parasitic infection.
Medical recommendations differ in relatively early diagnosis of such diseases in childhood.Enterobiosis and stool scraping and stool should be done twice a year.Before visiting the garden and the school, such tests require a child's parasite.And it should never be forgotten the prevention, which leads to the proper hand washing of food treatment and the quality of drinking water.
