The analysis on ljamblii how to hand over? Analysis of blood and stool

To accurately establish such a disease as lambliasis, the only reliable method is used - analysis on Giardia. How to take it? In this case, laboratory diagnostics help to reliably detect the presence of this disease, since there are no specific signs of this pathology. Only correctly conducted tests can give an accurate result. Let us consider this process in more detail.

What are lamblia?

These are the simplest single-celled microorganisms that live in the digestive tract of the human body. Transmission of this pathogen is carried out by the fecal-oral route. The shell (cyst) is very resistant to external influences, so the intestinal lamblia is viable enough in the environment. Since infection of a healthy person is carried out from the carrier of the pathogen, the cyst is often detected in the feces. Around the world, 500 million people fall ill with this ailment, of which 200 million are newly diagnosed patients.

How is lambliasis manifested?

This disease often occurs asymptomatically. The infected person does not bother, and the clinical signs do not appear in any way. The affected intestine can be troubled by abdominal pain, loose stools, rumbling and flatulence. From the gastrointestinal tract this illness manifests itself as poorly treatable dermatitis, eczema, urticaria. Less often, the lambliasis affects the gallbladder. Most often, the person is concerned about pain in the right ribs, unpleasant taste in the mouth, etc. The intestinal lamblias affect the child more often. This is explained by the fact that children rarely observe the rules of personal hygiene.

Diagnosis of Giardiasis

Diagnosed this disease is quite difficult. Thanks to laboratory methods, it is possible to detect directly the pathogen, its DNA, antigen and antibodies, which begin to circulate in the blood in response to the penetration into the human body of this microorganism. The analysis on ljamblii: how to hand over and that take in this case? To this end, investigated feces, blood and bile. Each diagnostic method has its strong and weak side. To make the result more informative, it is necessary to properly prepare for the delivery of biological material.

Stool examination

This is the most common and easily accessible diagnosis. The analysis on ljamblii how to hand over? For this, the biological material is collected in a container or other clean container in the morning. The sample is taken from different places of feces, and it must be delivered to the hospital as soon as possible. If the feces reveal cysts, then the diagnosis of "Giardiasis" is confirmed. Living lamblia in biological material can be found only if it was no more than 20 minutes after its collection.

For the analysis to be carried out, three grams of feces are required, and it is best if it is liquid. If collection of feces was carried out more than four hours ago, the effectiveness of the study is significantly reduced. If you can not deliver the sample quickly to the hospital, you can use a container with a special preservative, which is taken in advance in the laboratory.

The analysis of feces on lamblia is not in all cases reliable. This is explained by the fact that parasites trapped in the intestine develop intensively only after 2 weeks, so it is not possible to detect them during this time. The accuracy of such an analysis is only 50-70%. For greater effectiveness, it is recommended to take the feces four times with intervals between the analyzes in three days.

Enterotest

This is a new method of diagnosis, which is becoming more popular. Its conduct lies in the fact that a person swallows a gelatin capsule containing a nylon thread. Once inside the intestine, the capsule begins to dissolve. The lamblia adhere to this thread, which leaves the body with the feces after 2 hours, and it is subjected to examination.

Blood test for Giardia

With the help of such immunological diagnostics, specific antibodies in the blood are detected that help to fight with various microbes. Such antibodies are special proteins that destroy harmful viruses and bacteria in the human body, they are abbreviated as lg. In the blood of a person infected with Giardia, antibodies lgM begin to appear, which after a while are replaced by IgG antibodies. If the blood test showed the presence of IgM, then this indicates that the pathological process takes place in the acute phase. Antibodies lgG indicate a chronic process.

The analysis of a blood on ljamblii hand over in the morning on an empty stomach. 10 hours before that, you can not eat anything, it is also not recommended to drink tea, coffee, juices, alcohol. Blood is taken from the vein. If the patient takes the means to suppress the function of the immune system, then he must certainly inform the laboratory assistant and the doctor about it.

Such an immunological diagnosis can not be called sufficiently effective, as antibodies to lamblia completely disappear from the blood after 2-6 months. In addition, immunoglobulins of class M and G are able to appear in response to ingestion of other bacteria and parasites.

Giardiasis in children

This disease is very common among children, because they like to gnaw nails or caps of handles that are infected with lamblia. Also, this pathogen is often found in babies because of the insufficiently developed protective mechanism of the gastrointestinal tract. Giardia, penetrating into the small intestine, violate the integrity of its mucous membrane, resulting in inflammation. All this is accompanied by spasms, a violation of digestion, poor absorption of vitamins and nutrients.

Disease in young children begins as an acute intestinal infection, accompanied by a slight rise in temperature, diarrhea, vomiting. Chronic infection manifests itself in the following way: bloating and its rumbling, lagging of the tongue with a thick coating, pallor of the skin, alternation of constipation and diarrhea. There is increased fatigue, nervous excitability, irritability.

If parents notice such symptoms, then the child should be shown to the doctor who will prescribe the appropriate examination. The analysis for lamblia in a child consists in examining its feces for cysts of the pathogen, but this method is not 100% informative, because microorganisms can not always be detected. A more expensive assay is the ELISA method, when antibodies to the pathogen are detected in venous blood, but can be detected only three weeks after infection. To analyze the lamblia in a child was more effective, experts recommend combining several methods of diagnosis.

Where is the analysis for the pathogen?

Laboratory research is a fairly accurate method of medical diagnosis. Analysis of feces, urine, blood and scrapings of the skin can not only determine the overall health of the patient, but also to reveal the pathological condition of various organs.

Where to pass the analysis on ljamblii? This can be done in laboratories and private clinics, as well as in municipal polyclinics. In this case, the patient can choose which study is best for him to go through.

Conclusion

Thus, if a doctor has prescribed an analysis for lamblia how to take it, he should also explain, because in some cases special training is required for this. To identify the completeness of the disease, the doctor can prescribe a comprehensive diagnosis. It should not be neglected, because timely treatment promotes recovery without the occurrence of complications.
