Blood testing for parasites: symptoms of the disease, a general effect on human health

Blood testing for parasites

So far there is no reliable diagnostic method that results in one hundred percent result in relation to the pathogens and the degree of process activity.Compared to other methods, a blood test for parasites is the most accurate.Only in this way can information about the presence of a certain microorganism, regardless of the cycle of its vital activity from the formation of egg and larva to an adult.

Why is the exact diagnosis of helminths important?Almost all antiparasitic active ingredients presented on the pharmaceutical market have a wide range of activities in relation to different groups of worms.

Depending on the type of disease, the treatment duration can differ from 1 day to several months.At the same time, helminths affect the work of the entire human body.

Their development is accompanied by physiological changes such as:

  • Desensitization (constant allergic reaction).
  • Persistent lack of vitamins and various elements.In parasitic invasion, the structure of the 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).Increasing vascular permeability.
  • The development of chronic digestive pathologies (liver and bile character disease, inflammation of the pancreas, intestines), endocrines (diabetes), bronchopulmonal (bronchial -asthma) system.
  • Tightening allergic diseases.
  • Emotional disorders (chronic fatigue, irritability, moodlessness, insomnia, constant alarming, pathological hyperactivity).
  • Exercise on the difficult course of the disease through viruses and infections due to immune deficiency.

Confirmation of the diagnosis by a blood test from the vein on parasites is also recommended when specific symptoms of helminthiasis occur.Let us live with the most common apartments.The possible infection with pinworms (enterobiosis) is detected by itching in the anus area, which increases significantly in the evening and night.Its intensity depends on the power of the invasion.Sometimes it is not limited to the anus, but applies to the external genitals.Constant combing can cause infectious complications.

The invasion of the blazothal (trichocepales) is accompanied by a general malaise, an increased fatigue, pain in the right Iliac region, diarrhea is constantly replaced by constipation, sometimes a bloodstone is defined in the feces.The Strongyloidosis runs with constant temperature fluctuations, rashes on the chest, buttocks, the belly, the lower back and the hips, the stench diaper (up to 7 times a day).

Signs of trichinellosis are symptoms of acute poisoning, swelling of the face, severe muscle pain.It is dangerous to defeat almost all internal organs and central nervous systems.Toxocarosis is also characterized by dry coughs.Sometimes toxocary larvae with blood flow enter the brain.In this case, the patient can have cramped seizures and other neurological symptoms.

Almost all parasites are characterized by a number of clinical signs that are from:

  • Pain and rumbling in the stomach;
  • Nausea, less often - vomiting;
  • Stool violations;
  • Flatulence;
  • Allergic manifestations.

The most common method for diagnosing helminthiasis is currently a serological blood testing immunosorb duck to detect parasites.The decoding of this study is based on the detection of certain antibodies that are produced in response to antigens of foreign microorganism.

The advantage of immuno -shaping analysis (Elisa) is versatility.Such technology applies to the diagnosis of worms in both adults and a child.Treatment with different drugs has no significant influence on the results.The only thing that can affect the production of antibodies is the condition of the immune deficiency.In addition, this blood test is comprehensive for parasites, ie several pathogens can be identified at the same time

How to check for parasites, which tests have to prepare, prepare for research

This is how you do tests for parasites

How to check parasites, which tests can be specified in the clinical and diagnostic center.Now they offer many packages for complex diagnosis, including research into all common helminths and protozoa.His behavior does not require any special training.

In order to achieve reliable results, doctors recommend eating 8-10 hours before the analysis in the morning in the morning.In addition, they are recommended to refrain from eating fat and sweet food.Stress, intensive physical exertion should be avoided.If the use of drugs falls into the early days, you have to transmit it for several hours and drink it after the analysis.

Blutzun consists of veins.1-3 ml is sufficient to carry out the study.Then the nurse asks to bend your hand on the elbow and stay in this position for 10-15 minutes.This is necessary to prevent the formation of a bruising.The result will be finished in 3-5 days.

In medical literature, the IFA methodology is described using a specific terminology, which is simply incomprehensible to a person without adequate training and is simply interested in how to orientate the tests based on parasites.

Under the conditions of the laboratory, take a special tablet with cells in which an antigen of a certain parasite is reserved.A small amount of blood serum is added there.The photometry is then carried out using the devices, in which certain markers are rated.The "classic" study includes: Giardia, Toxoplasmes, Trichomonas, all pathogens of Helmintias (Pinworms, Ascarides, Toxokars, Echinococci, Opistarchie, Trichinella).

As a result of Elisa, three types of antibodies can be distinguished:

  • IGMAfter 2.5-4 weeks of infection;
  • Iga, is made from the first days of the disease and determined to healing;
  • IgGDiscovered from 4 weeks of the disease, a decrease in the tider only occurs after 1-1.5 months after recovery.

The conclusion of the presence of a parasitic infection is based on the relationship of the ratio of these antibodies.Her absence shows 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 various failures in the operation of the immune system.Therefore, not only the data from Elisa is taken into account in the case of a diagnosis, but also a clinical picture.If necessary, the patient is sent for additional examinations.

Analyzes for parasites in adults and children

How to prepare for parasites for tests

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 signs of long -term, which lasts several months, an increase in eosinophilic levels (normal values fluctuate within 1 to 5%), with some types of helminth anemia possible (the concentration of hemoglobin is reduced).

A frequent analysis of parasites in a child is a well -known scratch for all enterobiosis.

In order to get this immediately after awakening, without getting out of bed and without washing, it is necessary to press the buttocks and attach a piece of adhesive tape to the anal opening and the skin around you.Then it is glued to the object and returned to the laboratory for 1.5 hours.

With this study, however, you can only determine a kind of parasites.It is absolutely not suitable for the identification of lambia and other protozoa.The Calais analysis is more of a hint.In this case you can recognize larvae of Ascaris and different worms, pathogens of helminthiasis, parasitically in the intestine.However, a negative result does not always mean the lack of an illness.Various tests for parasites in a child are therefore required for a reliable diagnosis.

A negative analysis of feces can turn out if the worms have not yet reached the final parts of the digestive system or that they have already exceeded the propagation cycle.Some medications can also affect the data.It is therefore recommended to repeat the study after a few days.

However, the most reliable analysis of parasites in adults and child is the diagnosis through 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 this study method is negligible with this study method.The analysis also results in a precise result in the early stages of the invasion.

PCR is usually prescribed to confirm the diagnosis.The widespread use of this method with a preventive goal limits the high costs.In adults, the statements for the examination of parasites are problems with immunity, general deterioration in the fountain, the temperature of the unclear etiology, cough and other helminthiasis symptoms.However, it is recommended to start the diagnosis with a regular faecher analysis that can be handed over in any clinic.

Important!The treatment should only begin after tests on parasites in adults have been carried out, and the confirmation of the helminthian invasion has been preserved.Taking drugs in the event of parasitic infection can cause serious complications.

The medical recommendations differ in the relatively early diagnosis of such diseases in childhood.It is necessary to take a scratch for enterobiosis twice a year and to the feces on the egg loader.Such tests for parasites in a child are required before visiting the garden and school.And in no case, prevention should not be forgotten, which corresponds to frequent laundry of the hands, which correspond to the treatment of food and the quality of the drinking water.
