Giardiasis is a disease that is provoked by lamblia parasitizing the small intestine. Disease refers to dangerous pathologies, because of its violation of parietal digestion and peristalsis. The first symptoms of Giardiasis can not cause suspicion. And only after a few days the patient realizes that nausea, bloating, pain in the navel, a sharp change in diarrhea constipation, which are not treated with proven drugs, may be signs of lambliasis. In order to detect the presence of parasites in the body, it is necessary to conduct a study in a medical laboratory.
What analyzes hand over on ljamblii?
There are two effective studies that can unmistakably indicate the presence or absence of parasites:
- The analysis of a blood on ljamblii. The infection gets into the blood after a week, after infection, so the test is performed when the signs of the disease become very obvious.
- The analysis of a feces on ljamblii. It has a clear advantage, as it allows to detect not only the presence of infection, but also the eggs of Giardia. But at the same time, the test has some difficulties, since the collection of feces before the study should take no more than twenty minutes, ideally - 5-7 minutes, because the material should preserve its original temperature as best as possible. Another feature of the analysis is that the feces must be liquid - this will ensure the reliability of the result.
Preparation and analysis
Before donating blood or feces for analysis to lamblia cysts, it is necessary to adhere to some recommendations:
- 10 hours before the test, you can not eat, even the easiest.
- During the last 10 hours before collecting the material you can use only purified water, it is forbidden to drink coffee, tea, compote, juice, milk and other drinks.
In case of violation of recommendations, it is necessary to inform the attending physician about this in order to postpone the date of passing the test.
For the analysis of blood on ljamblii blood in a small amount from a vein is taken.
PCR method
In order to confirm the result of the tests, sometimes the patient is sent to pass an analysis on giardia using the PCR method . This is a highly accurate way of diagnosing various kinds of diseases. In this case, the infection is detected by the method of DNA identification of parasites. To carry out the test, any biological material of a person is suitable:
- blood;
- urine;
- saliva and so on.
Special enzymes are added to the test tube with the material, which synthesizes a copy of the DNA of the infection, after which the presence of the organism is easily revealed.
