What tests should be done to identify bugs?
Zxp> Tests for insects should be done regularly to identify the disease in a timely manner. The most well-known of them is the analysis of feces, which is done before getting a job or traveling to a sanatorium, but only this andNot the most reliable way to identify a parasite. A combination of tests will give the most accurate answer.what tests exist for bugs
The list of examinations must be long enough to identify the parasites.
Main are:
- The analysis of feces, also called worm eggs, is the most common method. Advantages - large scale use, no need for complex equipment. Minus - lack of accuracy;
- for ELISA, aka blood test worms. Professionals - High accuracy. Opposite - Only a few stages of parasitic development are detected, at other times the result will be questionable;
- Analysis of other biological media (urine, sputum, duodenal contents, epidermis). Professionals - allows you to identify parasites in localizations that are not available for other analyzes. Opposite - significant discomfort to the patient. Is associated with.
Typically, a patient is prescribed a combination of multiple tests to identify the parasite. The criterion for recovery is considered to be a negative ELISA result and several negative results of studies of the biological environment where insects were detectedWas.
Stool analysis for worm eggs
Most insects live in the intestines, so the most common test for worms is stool testing. Before they are hospitalized, sent to a sanatorium or children's camp, as part of a health book, Regular medical examinations are prescribed for adults and children. In addition, this analysis is taken by people who have been in contact with infected patients who have eaten unbaked foods, who have seen worm symptomsHuh.
There is no need to prepare specifically for analysis, you can collect feces at any time of the day, but the most commonly indicated is morning stools. Immediately before delivery, you should avoid urine impurities. And the perineum must be washed to discharge from the genitals.
Stools are collected in a special container for analysis for insects. It is sealed, and a special spoon is attached to collect the material. To collect the most informative part of the material, you need to collect the stool. There is a need to take a sample from the middle of one part. The container should be filled about one-third. You have to deliver it to the laboratory on the same day.
In the laboratory, a specialist examines feces under a microscope and identifies the eggs of the worms. Most of them have a characteristic shape that allows you to correctly determine the type of worm. Based on the results of the analysis, a conclusion is issued regarding the absence of eggs or their presence and type, after which treatment is determined.
This is the most common but least accurate worm test. The reason is that this part cannot contain eggs that are in the container, despite the fact that there are worms. Therefore, if the patient complains of symptomatic symptomsIs or is exposed to the source of infection, it is necessary to undergo 5-6 tests with an interval of 2-3 days. In this case, the probability of detecting the parasite increases significantly. With the study of feces, otherDiagnostic procedures are prescribed.
skin scraping
This analysis usually complements stool analysis. The most accurate results are obtained when diagnosing pinworms, which lay eggs on the surface of the skin near the anus. Indications for such analysis are children and adults. Regular examination of, registration of child in kindergarten, school, camp or sanatorium, hospitalization of children and adults, suspicion of pinworm infection (itching in the anus, digestive disorders, contact with sick people). Most often, childrenPeople suffering from this disease, who tell the name of the worm (children's pinworm).
There is no need to prepare the analysis for the worms, you should not wash the perineum - so it is possible to wash the eggs of the parasites, you have to avoid bathing at night or before bathing. The analysis is done in the morning. A special film is used that collects material from the skin of the interglutial fold. The study is also done under a microscope. It does not detect helminithesis except pinworms.
urinal
This test is the least prescribed, as the parasites almost never live in the urine. Conditions are possible if pinworms are found in the analysis of the parasite, but this indicates a violation of the rules for passing the analysis - parasitesAnd their eggs enter the container from the skin of the perineum. Most often, this condition occurs in girls, less often in boys.
But still there are indications for testing. In the kidneys and urinary organs, some tropical parasites live, which a person is "rewarded" by visiting Asian and African resorts. With the increasing availability of foreign recreational areas, ourThe prevalence of parasitic untouchables is also increasing for the country. For this reason, it is advisable to conduct urine and blood tests for insects after visiting the resorts.
Types of insects found in urine:
- Trichomonas;
- distom hematobium;
- Filaria sanguinis hominis;
- Takenia echinococcus.
Urine may also contain liver parasite eggs - Echinococcus and flukes.
sputum analysis
There are many parasites that spend all or part of their lives in the lungs. Their presence is not symptomatic - inflammatory events develop in the bronchi (swelling, cough, wheezing). Hemoptysis, unknown originOther events from K. pneumoniae and lungs may be noted.
Parasite found by sputum worm test:
- ascaris - they require oxygen in the larval stage;
- Echinococci and alvococci - tissue parasites that live in the parenchymal organs including the lungs;
- dwarf fluke - lives mainly in the lungs;
- Strongloidosis, noncutterosis - a parasite characterized by intestinal localization, the location in the lungs is found as atypical.
For collecting sputum, no special preparation is required, but it is advised to brush your teeth and take the ingredients in the morning. Before that, it is useful to drink plenty of fluids - this causes mucus. Withdrawal improves. Container containers must be cleaned, but not necessarily sterile - bacteria do not play a role in diagnosis. In this case, both the parasites themselves and their eggs are detected. If the patient coughs up the sputumIf unable, it is removed from the trachea using vacuum suction.
It is possible to use drugs that improve sputum discharge, stimulate its formation to obtain more accurate results of analysis for worms. In combination with blood tests for worms, it gives very accurate results. Unlike male tests, eggs are more likely to be found.
blood test
ELISA, or blood test for worms, is the most accurate way to determine them. Helminths cause a powerful reaction from the immune system - the content of eosinophilic leukocytes increases, immunoglobulin production increases. , And antibodies specific to the parasite. It is upon their detection that the ELISA method is produced.
Antibodies to the parasite are highly specific - they can be diagnosed clearly, while they are present only in the blood in the presence of the parasite and within 3 weeks of their disappearance.
Analysis requires blood from a vein. No special training is required. Results can be obtained within two days. Accuracy is close to 100%, specificity of antibody allowing for an incorrect resultThe criterion of recovery is a negative result after one month of treatment.
Analysis of duodenal contents
The bile ducts and pancreas ducts open in the duodenum. These organs are often affected by echinococcosis and opsythoriasis. Parasites lay eggs, which pass through the intestinal tracts. Allows to identify these diseases more accurately than an analysis of.
The material is taken on an empty stomach with duodenal examination. If the patient has a pronounced gag reflex, pain is relieved. The procedure is quite unpleasant, therefore, it is used only in cases whereResults of other examinations are questionable.
when do you need to test for bugs
tests for worms should be taken under the following conditions:
- The patient is experiencing symptoms of helminth infection;
- The patient has been in contact with sources of invasion (sick people, unused products, areas with an adverse sanitary environment);
- Confirmation is required that the patient is not the source of infection (employment, health records, out-of-town recreation, hospitalization).
how to test for bugs
To test for worms, you must take a referral from your GP. Most exams do not require preparation, and if there are nuances, the doctor will explain them when scheduling a study. Referral to the doctor. A prompt is required to write.
In commercial clinics, you can take an analysis regardless of the indication. The price varies greatly. The time to get the results of softening and scraping is about a week, depending on the workload of the laboratory, urine, sputum, Blood analysis is approximately 2 days.
can helminths be detected using test
Analysis for worms detects most types of parasites - intestines and extra types. There is a blood test for the most accurate insects, which allows you to identify the parasite.
