So far, there is no reliable method of diagnosis that would give one hundred percent result in relation to the pathogens of the disease and the degree of process activity.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 correct diagnosis of helminths important?Almost all anti -masticistic agents presented in the pharmaceutical market have a wide range of activity in relation to different groups of worms.
However, the treatment period varies, depending on the type of disease, it can be from 1 day to several months.At the same time, poisons affect the work of the whole human body.
Their development is associated with such physiological changes as:
- Desensitization (continuous allergic reaction).
- Continuous lack of different vitamins and elements.With parasitic occupation, the structure of the intestinal epithelial cells is damaged, as a result, the absorption of various nutrients is disturbed.
- Changes in the hormonal background.
- Holy urban disorder (this is also reflected in the usual blood test).Increased vascular permeability.
- The development of chronic digestive pathologies (liver disease and bile tract, inflammation of the pancreas, intestines), endocrine system (diabetes), bronchopulmonary (bronchial asthma).
- Irritation of allergic diseases.
- Disordishes emotional disorders (chronic fatigue, irritability, mood, insomnia, constant alarming, pathological hyperactivity).
- Exercise in the difficult course of diseases caused by viruses and infections due to immunity.
Confirmation of diagnosis from a blood test from vein to parasites is also recommended when specific symptoms of helminthiasis appear.Let's stop at the most common.Possible infection with pinworms worms (enterobiosis) is evidenced by itching in the anus area, increasing significantly in the evening and night.Its intensity depends on the power of the occupation.It is sometimes not limited to the anus, but applies to the external genitals.Continuous combination can cause infectious complications.
The occupation of blazothale (trichocephales) is associated with a general disease, increased fatigue, pain in the right iliac region, diarrhea is constantly replaced by constipation, sometimes a blood stone is marked in the feces.Strongyloidosis continues with constant temperature fluctuations, redness on the chest, buttocks, abdomen, lower spine and hips, glowing diarrhea (up to 7 times a day).
Signs of trichinellosis are symptoms of acute intoxication, facial swelling, severe muscle pain.It is dangerous to defeat almost all internal organs and the central nervous system.Toksocarosis is also characterized by dry cough of the night.Sometimes the larvae of the toxicity enter the brain with the 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 signs, consisting of:
- pain and rumble in the abdomen;
- nausea, less often - vomiting;
- stool violations;
- Flatulence;
- Allergic manifestations.
Currently, the most common method of diagnosing helminthiasis is a serological immunosorbent blood test for the detection of parasites.The decoding of this study is based on the detection of certain antibodies, which are produced in response to foreign microorganism antigens.
The advantage of immunoformal analysis (ELISA) is its versatility.Such a technique is applicable to the diagnosis of worms in both adults and a child.Treatment with different medicines does not have a significant effect on the results.The only thing that can affect antibody production is the state of immunity.Moreover, this blood test for parasites is comprehensive, that is, some pathogens can be identified at the same time
How to check for parasites, which tests should you get, preparation for research
How to check the parasites, which tests can be given at the clinical and diagnostic center.Now they offer many packages for complex diagnosis, which include research in all ordinary helminates and protozoa.Her behavior requires no special training.
But to get reliable results, doctors recommend not eating 8-10 hours before the analysis, blood in the morning strictly on an empty stomach in the morning.In addition, they are advised to refrain from fatty and sweet food, alcohol.Stress, intense physical exercise should be avoided.If the drug use falls in the early time, you should transfer it for a few hours and drink it after the analysis.
The blood fence is made of vein.For conducting the study, 1-3 ml is sufficient.Then the nurse requires to bend his hand to 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 for 3-5 days.
In medical literature, the IFA methodology is described using specific terminology, which is simply incomprehensible to a person without proper education, who is simply interested in how to control the parasites, what tests to take.
In the laboratory conditions, they receive a special cell tablet in which an antigen of a particular parasite is preceded.A small amount of blood serum is added.Then, using the equipment, the photometry is done, during which the specific markers are evaluated.The "classic" study includes: giardia, toxoplasma, trichomonas, all pathogens of helminthiasses (pinworms, ascarides, toxicity, echinococci, opistarkia, trichinella).
As a result of ELISA, three types of antibodies can be distinguished:
- Igm, detect at 2.5-4 weeks infection;
- Iga, produced from the first days of the disease and determined to the cure;
- Igg, detected starting from 4 weeks of illness, a decrease in titles occurs only after 1-1.5 months after healing.
The conclusion about the presence of a parasitic infection is based on the ratio of these antibodies.Their absence indicates that there is no helminthic occupation.ELISA's specification and reliability is about 90%.
The probability of positive positive and false negative results occurs in various failures in the functioning of the immune system.Therefore, when making a diagnosis, not only ELISA data is taken into account, but also a clinical view.If necessary, the patient is sent for additional examinations.
Analysis for parasites in adults and child
There are other ways to identify helminthic occupation.
The presence of such a disease can be assumed by a general blood test.
They pay attention to such signs as a long-term, which lasts several months, an increase in the level of eosinophils (normal values fluctuate within 1-5%), with some types of helminths anemia is possible (decreased hemoglobin concentration).
A common analysis of parasites in a child is a scrap known to all of an enterobiosis.
To do this, immediately after waking up, without getting out of bed and without washing, it is necessary to push the buttocks and attach a piece of tape to the anal opening and the skin around it.Then it is attached to the article and for 1.5 hours attributed to the lab.
But this study allows you to determine only one type of parasite.Absolutely absolutely not suitable for identifying lambia and other protozoa.Calais analysis is more indicative.In this case, you can detect ascaris larvae and various worms, pathogens of helminthiasis, parasitic intestine.But a negative result does not always mean the lack of an illness.Therefore, for reliable diagnosis, various tests for parasites in a child are required.
A negative analysis of the feces can result if worms have not yet reached the last parts of the digestive system or they have already passed the spread cycle.Some medicines can also affect data.Therefore, it is recommended to repeat the study after a few days.
But the most reliable analysis of parasites in an adult and child is the diagnosis by polymerase chain reaction or abbreviated PCR.At the same time, experts determine the DNA of the pathogen in the patient's blood.It is clear that with this method of study, the probability of fake data is negligible.The analysis will give an accurate result even in the initial stages of the occupation.
Usually PCR is prescribed to confirm the diagnosis.The widespread use of this method with a preventive purpose limits the high cost.In adults, evidence of parasitic examination are problems with immunity, overall deterioration in well -being, temperature of vague etiology, coughing and other symptoms of helminthiasis.However, it is recommended that you begin diagnosing with a regular fecal analysis, which can be delivered to any clinic.
Important!Treatment should only begin after the tests for parasites to adults have been obtained, and confirmation of helminthic occupation has been obtained.Taking the drug in case of suspicion of a parasitic infection can cause serious complications.
Medical recommendations vary in the relatively early diagnosis of such diseases in childhood.It is necessary to get a scrap for enterobiosis and feces on the egg reader twice a year.Such tests for parasites in a child are required before visiting kindergarten and school.And in no case should it be forgotten for prevention, which descends on frequent washing of hands corresponding to the treatment of food and the quality of drinking water.
