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 Giardia?
These are the simplest unicellular 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 stool. Around the world, 500 million people fall ill with this ailment, of which 200 million are newly diagnosed patients.
How does lambliasis manifest?
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 disturb with 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, an unpleasant taste in the mouth, etc. The child intestinal lamblia affects more often. This is explained by the fact that children rarely observe the rules of personal hygiene.
Diagnosis of Giardiasis
This disease is diagnosed rather difficult. Thanks to laboratory methods, it is possible to detect directly the pathogen itself, 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. For the result to be the most informative, it is necessary to properly prepare for the delivery of biological material.
Stool examination
This is the most common and easily available 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. Live 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, then 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 always reliable in all cases. This is explained by the fact that intestinal parasites 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 diagnostic method that 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. Giardia sticks to this thread, which leaves the body with feces after 2 hours, and it is subjected to examination.
Blood test for lamblia
With the help of such an immunological diagnosis, 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, also it is 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 immunological diagnostics 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 ingress of other bacteria and parasites into the body.
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 insufficiently developed protective mechanism of the gastrointestinal tract. Lamblias, 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 the venous blood, but they can be detected only three weeks after infection. That the analysis on ljamblii at the child was more effective, experts recommend to combine some methods of diagnostics.
Where is the analysis done for the pathogen?
A laboratory study is a fairly accurate technique for 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
Therefore, if a doctor has prescribed an analysis on 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.
