To date, there is no reliable method of diagnosis that gives one hundred percent result in the pathogens of the disease and the degree of activity activity.Compared to other methods, a blood test for pests is more accurate.Only in this way can information about the presence of a particular microorganism can be obtained, regardless of the cycle of vital activity from the formation of egg and larvae in an adult.
Why is the exact diagnosis of helmets important?Almost all the antiparasitic 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, can be from 1 day to several months.At the same time, helminths influence the work of the whole human body.
Their development is accompanied by such normal changes as:
- Desensitization (constant allergic reaction).
- Persistent lack of vitamins and various elements.With a parasitic invasion, the structure of epithelial intestinal cells is damaged as a result, the absorption of various nutrients is disturbed.
- Changes in the hormonal background.
- Holy disorders (this is also reflected in the usual blood test).Increase vascular permeability.
- The development of chronic digestive pathologies (liver disease and bile, pancreas inflammation, intestinal), endocrine (diabetes), bronchopulmonary system (bronchial asthma).
- Examination of allergic diseases.
- Emotional disorders (chronic fatigue, irritability, mood, insomnia, stable worrying, pathological hyperactivity).
- Exercise in the difficult course of diseases caused by viruses and infections due to immunodeficiency.
Confirmation of diagnosis by vein -testing blood test in parasites is also recommended when specific symptoms of helminths occur.Let's dwell on the most common.Possible infection with pinworms is evidenced by itching in the anus area, increasing significantly at night and night.Its intensity depends on the power of the invasion.Sometimes it is not limited to the anus, but applies to external genitals.Continuous hairstyle can cause infectious complications.
The invasion of Blazothale (Trichocephales) is accompanied by a general adversity, increased fatigue, pain in the correct iliac region, diarrhea is constantly replaced by constipation, sometimes a blood donation is noted in the stools.The strong term proceeds with constant temperature fluctuations, chest rashes, buttocks, abdomen, lower back and hips, diarrhea (up to 7 times a day).
The signs of trilogy are symptoms of acute toxicity, facial swelling, severe muscle pain.It is dangerous to defeat almost all internal organs and the central nervous system.Toxocratosis is also characterized by night dry cough.Sometimes toxocari larvae enter the brain with blood flow.In this case, the patient may have spasm epileptic seizures and other neurological symptoms.
Almost all parasites are characterized by a set of clinical points, consisting of:
- Pain and flickering in the belly.
- Nausea, less often - vomiting.
- infringements of the stools;
- inflation;
- allergic events.
Currently, the most common method of diagnosing helminth is a serological immunoodoring blood test to detect pests.The decoding of this study is based on the detection of certain antibodies, which are produced in response to a foreign microorganism antigens.
The advantage of immunodeficiency analysis (Elisa) is its flexibility.Such a technique applies to the diagnosis of worms in both adult and child.Treatment with various drugs has no significant effect on results.The only thing that can affect antibody production is the condition of immunodeficiency.In addition, this blood test for pests is comprehensive, that is, many pathogens can be identified at the same time
How to check for pests, what tests you should do, preparation for research
How to check the parasites, what tests can be given to the clinical and diagnostic center.They now offer many packages for complex diagnostics, which include research on all common helminth and protozoa.His behavior does not require special training.
But to get reliable results, doctors recommend that they do not eat 8-10 hours before analysis, blood in the morning strictly on an empty stomach in the morning.In addition, they are advised to avoid fatty and sweet foods, alcohol.Stress, intensive physical activity should be avoided.If the use of drugs falls early, you should carry it for several hours and drink it after the analysis.
The blood fence is made of vein.For the study, it is enough 1-3 ml.The nurse then asks to bend the hand on the elbow and stay in this position for 10-15 minutes.This is necessary to prevent bruising formation.The result will be ready in 3-5 days.
In medical literature, the IFA methodology is described using specific terminology, which is simply incomprehensible to a person without proper training, who is simply interested in how to control parasites, what tests they should receive.
In the conditions of the laboratory, they take a special tablet with cells in which an antigen of a particular parasite is predetermined.A small amount of blood serum is added there.Then, using the devices, a photo is performed during which specific indicators are evaluated.The "classic" study includes: Giardia, toxoplasms, Trichomonas, all Pinworms, Ascarides, Toxocars, Echinococci, Opistarchy, Trichinella).
As a result of Elisa, three types of antibodies can be distinguished:
- Igy, detects in 2.5-4 weeks of infection.
- Hare, produced from the first days of the disease and determined to treatment.
- Scandal, Discovered starting at 4 weeks of the disease, the reduction of titles only occurs after 1-1.5 months after recovery.
The conclusion on the presence of parasitic infection is based on the ratio of these antibodies.Their absence shows that there is no helminth invasion.Elisa's specialty and reliability are about 90%.
The likelihood of false positive and false negative effects occurs in various failures in the functioning of the immune system.Therefore, during the diagnosis, not only ELISA data, but also a clinical picture are taken into account.If necessary, the patient is sent for additional tests.
Analyzes for pests in adults and child
There are other ways to identify the helminth invasion.
The presence of such a disease can be considered by a general blood test.
They pay attention to such signs as in the long run, which lasts several months, it is possible to increase the level of eosinophils (normal values range within 1-5%), with certain types of helminths anemia (decrease in hemoglobin concentration).
A common analysis of pests in a child is a well -known scraping in all the entertainment.
To do this, immediately after awakening, 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.It is then glued to the object and is attributed to the laboratory for 1.5 hours.
But this study allows you to determine only one type of parasite.It is not absolutely suitable for the identification of Lambia and other protozogs.Calais resolution is more indicative.In this case, you can detect the Ascaris larvae and different worms, pathogens, parasitic intestines.But a negative effect does not always mean the lack of illness.Therefore, a reliable diagnosis requires various testing for parasites in a child.
A negative analysis of feces can be shown if the worms have not yet reached the end parts of the digestive system or have already passed the propagation cycle.Some medicines can also affect the data.Therefore, it is recommended to repeat the study after a few days.
But the most reliable analysis of pests in an adult and the child is the diagnosis of a polymerase chain reaction or shortened 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 likelihood of false data is negligible.The analysis will give an accurate result even in the early stages of the invasion.
Usually PCR is prescribed to confirm the diagnosis.The widespread use of this method with a preventive target reduces high costs.In adults, testimonies for examining pests are problems with immunity, general deterioration of prosperity, the temperature of vague etiology, cough and other symptoms of Helminth.However, it is recommended to start diagnosis with a regular stool analysis, which can be delivered to any clinic.
Great!Treatment should only start after adult pests tests and a confirmation of the helminth invasion has been taken.Taking drugs in the event of suspicion of a parasitic infection can cause serious complications.
Medical recommendations differ in the relatively early diagnosis of such diseases in childhood.It is necessary to obtain a scraping in the enterobilization and the stools in the egg -a reader twice a year.Such parasite tests in a child are required before visiting the garden and school.And in no case should it be forgotten for prevention, which comes under frequent washing of the hands that correspond to the treatment of foods and the quality of drinking water.
