According to experts, the growth of the infecting population of parasites is affected by tourism (invasion occurs through food and water in exotic countries), migration of the parasites are transferred to developed country flows of people from the countries of Africa and Asia.
Bulk shipments of contaminated products from Asian countries (fish and seafood), breaking technology in the manufacture of meat products, which are produced by uncontrolled companies from the contaminated raw material, dramatically increases the risk of infection in all layers of the population.
In the human body can live organisms that feed on his cells and intended food for him, giving nothing in return. These creatures are parasites.
Distinguish more than hundreds kinds of these organisms which can settle in all parts of the human body – from the esophagus to the brain. Various, and their size – from microscopic protozoa to meter worms. In humans live in two types of helminths:
Tests to identify the parasites are assigned to diagnose when:
Massive invasion or large size worms impair the functioning of the digestive tract and bile ducts, causing inflammation of the liver and constipation, the waste products of helminths provoke flatulence and diarrhea.
The body's response to substances secreted by parasites, leads to inflammatory diseases and pain of the joints, increased development of specific blood cells that cause allergies.
On the occurrence of parasites in the human body show growths and inflammatory disease of the skin – rash of various kinds, warts, boils.
Waste products secreted by worms in the blood, greatly weaken not only the immune but also the human nervous system, causing anxiety and depression, causing fatigue.
The state of chronic poisoning, constant stress, an acute shortage of nutrients in the body, which are caused by helminths – a direct path to the development of tumors.
Usually, the poisoning of the body and cause powerful allergic roundworms and Trichinella, bleeding and anemia due to injury of internal organs provoke anakilostomi, clogging the intestines and the lumen of the bile ducts can roundworm, acute nutrient deficiencies cause tapeworms. Tests for parasites allow you to properly establish the diagnosis of anemia, allergies, various disorders of weight and to appoint adequate treatment.
To confirm the diagnosis on the presence of worms in the body it is necessary to use the full range of available laboratory practices.
Most accurately confirm or refute the diagnosis can only:
Other used laboratory methods (x-ray, biorezonansnoe scanning) will not be able with complete certainty to confirm the presence of parasites in the body of the patient, but will help to identify lesions and to establish the possibility of the existence of parasites in the brain, retina of the patient.
Many people are interested in what tests you need to pass the patient to confirm glistnogo infection? Ways to detect parasites in the body are divided into:
One of the clinical methods (detailed analysis of feces for parasites) traditionally used in the diagnosis of worm infestation. But the method is not reliable – if the life cycle of the worms does not coincide with the study period and eggs are not detected in the faeces – this is not evidence of their absence.
For a more precise study carried out several cycles of research, but it does not guarantee the accuracy and completeness of analysis for the presence of parasites in the human body.
If there is a suspected infestation glistnuyu tissues (cisterikoz or trichinosis), biopsy, for a more complete diagnosis. Serological study of blood plasma allows to determine the localization of the infection in the human body (the intestines, brain, liver).
If feces or vomit has a copy of the parasite, biological research will help to make a diagnosis and establish a treatment plan, if fragments of the parasites is not enough to determine the type of infestation, is the multiple fence material and a few study cycles every 3-5 days.
Upon defeat worms in human organs, the doctor sends to the target analysis for the detection of parasites – diagnosis of those liquids in which exactly found their tracks (Kal if you suspect intestinal worms, gall – and liver lesions). What are the tests for this?
Assuming glistnuyu infestation on regular assignments will be General clinical examination and diagnosis.
The first method allows you to identify intestinal infestation by such parasites:
To determine the eggs of worms, their fragments and larvae, cysts, protozoa using microscopical methods. Usually after the detection of the biological material additional methods of analysis are applied.
Tests to identify the remains of parasites is repeated a month after the completion of the prescribed treatment. In total there will be three intake stool after 3-4 days to monitor the appearance of eggs. A negative value of the third blood test for parasites, treatment was effective.
Such an integrated analysis allows to detect parasites in the body due to the exclusion of the subjective factor in the analysis (occasionally, a technician may notice biological material worms). To determine the infestation using the method of polymerase chain reaction that detects DNA parazitiruyushego in the body of a human, even if he died or is in the stage of the cysts.
A detailed analysis for parasites are often able to detect their traces in a patient, even if the results of earlier tests were negative.
This analysis on the parasites of the blood can be diagnosed to 17 species, which will allow you to assign the correct and effective treatment.
Using this method it is possible to detect intestinal parasites and Giardia.
For research need several attempts, their form thus: the patient is given a laxative, after each stool sample is taken, numbered, and then the next day their analysis is carried out. Usually signs of infestations appear not earlier than 5-6 sample. Even if you receive a negative result, it is safe to say, that worms in the body no – the method has only 50% efficiency.
Laboratory method for the study of mucus from the rectum allows to determine infestation lyambliyami (which in many cases are provocateurs irritable bowel syndrome) and some other types of parasites. For analysis with the help of special mirrors selected smear of mucus, which is subjected to microscopic examination.
To determine infestation ostricami apply a swab of the perineum. This morning take a scraping from the area closest to the anus (the pinworms crawl out to lay worms at night).
The study of feces sometimes are able to detect infestation. A more informative analysis of blood – he would be the best way to confirm the existence of parasites and to diagnose tissue invasion (Echinococcus, vlasoglavy are parasitic in the tissues, do not release eggs in the intestine and stool analysis can not detect it).
To investigate the blood parasites is possible through the detection of antibodies to a specific species of worms that will reveal their presence, the depth of the destruction of the human body. What is the blood test for parasites, which will determine entrenched in the body of the pest?
The modern method uses the antibody that is specific for each species and are produced in response to the toxins secreted by helminths.
To identify helminth infection are used:
Enzyme-linked immunosorbent assay (ELISA) for parasites gives the opportunity to establish the fact of presence:
In some cases, a simple laboratory blood may indirectly indicate infection. Elevated levels of eosinophils (a type of leukocytes) is interpreted as an allergic response of the body. In many cases it shows on parasites such as roundworm, hookworm, pinworm.
On helminths may indicate undue reduction of mineralization of blood and fluctuations in the level of food enzymes.
For the most objective results, the patient must know how to be tested for parasites.
Dinner should be 8 hours before the blood donation when her rent in the morning – the patient not to eat Breakfast. Accepting spirits, beer and soft mixes stop for 48 hours, and sweet drinks for 24 hours before blood donation. 2 hours before that you can't smoke.
The medication is prohibited for 3 days before blood donation. If there are objective medical indications for drug therapy, before you take the test, you should discuss with your doctor. 24 hours before the procedure, you should not undergo ultrasound or CT scan, fluoroscopy.
To be tested for parasites adult needs from a vein on the hand, if it is determined by infection of the newborn, the blood taken from the umbilical vein.
The research will show (or not detectable) traces of parasitic infestation, the result will be the basis for selecting a doctor and treatment regimens. The repeated blood sampling required for ELISA when receiving vague results, or as a follow-up examination after treatment. Between the tests need to withstand 14 days.
After examination and medical history, the doctor will determine what to be tested for parasites. In addition to basic, traditional research may be applied:
Properly conducted research will help the doctor to determine the cause of the disease and do not treat non-existent disease.
