Methods for diagnosis of giardiasis

It happens that a person suffers for years from allergic reactions, stool disorders, skin rashes and a number of other unpleasant symptoms. It may be that the cause of the ailment is a common parasitic invasion - giardiasis. It is caused by unicellular organisms that enter the human body with contaminated water or unwashed vegetables and fruits and affect the human gastrointestinal tract. A patient with giardiasis secretes lamblia cysts with feces and may itself be a source of infection.

Symptoms of Giardiasis Infection


The first signs of the presence of lamblia in the human body occur soon after infection and persist for several weeks. This fetid loose stools, abdominal pain and flatulence. After about 2-3 weeks from the onset of the disease, it becomes chronic, the indirect signs of which are decreased performance, weakness, dizziness and headache, as well as distraction of attention and memory loss.Possible weight loss, anemia, allergic reactions, conjunctivitis and runny nose.

Modern methods of diagnosis of giardiasis


To this day, the most popular method for making the diagnosis of giardiasis is the examination of feces for Giardia cysts. The low efficiency of this method is primarily due to the fact that the isolation of cysts Giardia is not a continuous process, and it is impossible to know exactly when it will occur. That is why the analysis should be taken weekly for a month and a half. In addition, to detect cysts, it is necessary to examine the feces that are still warm, otherwise they will collapse and the laboratory technician will not be able to detect the presence of Giardia in the human small intestine at this time.
A relatively new highly effective method for the diagnosis of giardiasis is enterostest, for which the patient swallows a gelatin capsule with a nylon thread inside. In the intestine, the capsule dissolves, and Giardia stick to the thread. After the latter leaves the body in a natural way, the technician examines it under a microscope.
The most effective method of diagnosis, which allows not only to detect the presence of Giardia in the body, but also to assess the degree of damage they cause to the small intestine - this is a biopsy.Used less frequently due to the complexity and high cost of the procedure.
Finally, the diagnosis of giardiasis can be made by blood, in which the infected person has specific antibodies produced by the body to combat parasites. For a number of reasons, this type of diagnosis is not considered highly informative.
Having diagnosed and treated in a timely manner, it is possible to quickly get rid of Giardia. Observe hygiene, do not eat in unchecked points of the catering and boil water, and this problem will not affect you anymore.
