It is extremely difficult to determine the infection with lamblia by external signs. To diagnose giardiasis, it is necessary to undergo certain laboratory tests that allow you to establish the stage, the intensity of infection.

The analysis of feces for lamblia is considered the most convenient and reliable diagnostic method. Thanks to this technique, the doctor can choose the most effective therapy.

What to do in such a situation? To get started, we recommend reading this article. This article details the methods of dealing with parasites. We also recommend contacting a specialist. Read the article >>>

Why take a stool test for lamblia

The study of feces allows you to identify the presence of a parasite in the intestine, to find out the form of the course of the disease. An analysis is prescribed during treatment to track the dynamics of therapy, as well as 10 days after it - the best way to find out about the effectiveness of treatment.

This diagnostic technique allows you to detect not only adults, but also their cysts. In feces, the duodenal contents are examined.

The process of passing the analysis of feces for lamblia in a child and an adult

To prescribe a stool test, the patient must have the following clinical manifestations:

• increased body temperature;
• attacks of nausea, vomiting;
• constipation followed by diarrhea;
• bloating;
• education in the language of milk plaque;
• deterioration in the condition of the skin;
• psychoemotional disorders;
• allergic rash.

After the examination, the doctor prescribes the necessary tests for the patient. Only after studying the test results does it become possible to make an accurate diagnosis and choose a treatment method.

Training

The process of preparing for the analysis of feces for lamblia is no different from other analyzes of this type. The biomaterial must always be fresh, storage in the refrigerator for no more than 8 hours is permissible.

It must be obtained without the use of a laxative. The patient should stop using medications a week before the study. Feces must be placed in an airtight, sterile container.

It is important to exclude mixing of feces and urine - this distorts the final result. Some laboratories require that the material for research be as fresh, warm as possible.

It is unacceptable to hand over old material, as the test results will be meaningless. In fresh feces, Giardia can be seen in its natural form.

2 hours after a bowel movement, the parasite begins to feel discomfort due to the change in environment. As a result, lamblia can take the form of cysts, hiding behind a protective shell.

Material collection process

Feces are collected in the morning after waking up, but always before hygiene procedures. For research, you need to collect about 2 tsp. feces. Before a bowel movement, the bladder should be emptied to prevent mixing of urine and feces.

To collect material, you can use a special spatula and place it in a jar. You can buy it at any pharmacy. The collected material must be delivered to the laboratory within 8 hours (the faster, the better).

Decoding analysis

The physician interprets the results with other clinical findings. Giardia antigen can be detected in feces, which indicates giardiasis, but is not a reason to exclude the likelihood of invasion by other parasites.

If the results are negative, it is a sign of no infection. However, with such results, the tests must be repeated after a while. This will allow you to make the most accurate diagnosis.

How much does it cost and where can I take it

If you suspect an infestation with lamblia, you need to contact the nearest medical institution in the city. The doctor will prescribe a stool test for lamblia. You can collect the material at home and take it to the laboratory of the medical institution.

The cost of analyzing feces for lamblia depends on the method of its study, the location of the laboratory. Usually the price is around 600 rubles.

Alternative analyzes

Among the alternative options, the most effective are the PCR method, ELISA. PCR requires the study of feces for DNA fragments of the parasite. For maximum reliability, tests are taken several times.

The ELISA technique is based on the study of venous blood, the detection of lamblia antibodies. This technique is the most reliable (accuracy is about 90%). During the study, the presence of antibodies in the blood (Ig with markers M and G), which the immune system secretes to fight the parasite, is studied.

Research results can be positive, questionable, or negative. On their basis, the doctor selects a treatment method.

Giardiasis can be asymptomatic for a long time, which complicates the process of its diagnosis. Usually, the disease is discovered by chance during routine examinations, or at the stage of exacerbation, when severe symptoms appear.

If an invasion is suspected, it is better to abandon self-medication and go to the doctor for diagnostic measures and the choice of adequate therapy.
