Most parasitic infections today help to identify a well -designated analysis for worms.Diagnosis is carried out in specialized laboratories using the latest equipment and reagents.
Moreover, each analysis of parasites has a number of certain requirements for its implementation.In what tests should be handed over for worms and how to do it correctly, and also how to interpret them correctly, we understand below.
Types of tests for the identification of worms
There are several types of tests, the totality of the results of which may indicate a particular parasitic invasion.However, it should be remembered that only the attending physician can do the decryption of the results and making a diagnosis.
Blood test
One of the reliable and most informative (with an accuracy of 93%) methods for diagnosis on helminths is a blood test for parasites.In the circles of doctors, such a study is called ELISA (immuno -function analysis for parasites in the human body).The study allows you to identify in the blood serum the presence of antibodies that have formed in relation to antigens.That is, in relation to parasitic infections/individuals.
The advantage of such a blood test for parasites is the possibility of determining helminthic invasion in the early stages, when helminth is not yet capable of reproduction and does not lay off eggs that can be detected during a coprogram (a special analysis of feces for an egg -player).
It is important to understand that using such a blood test for parasites, the following parasitic infections can be identified:
- Opisthorchiasis;
- Lambliosis;
- Enterobiosis;
- Ascaridosis;
- Toxoplasmosis;
- Toxocarosis;
- Trichinellosis and others.
Blood on parasites is taken from a vein in the morning on an empty stomach.At the same time, before conducting the study, it is worth carrying out preparatory measures.
In particular, to conduct a blood test for parasites, you should adhere to such rules:
- Three days before the diagnosis, do not eat fatty, fried, complex dishes.Food should be simple and easy to digest;
- Three days before the study, you need to abandon alcohol and any drugs;
- The day before donating blood to worms, you need to limit yourself from excessive physical and psycho -emotional stress;
- For at least 3-4 hours, you should refuse smoking.
Important:Performing a blood test for parasites in compliance with all these rules allows you to get the most accurate result and eliminates the withdrawal of a false positive result.If the reader is interested in how much time the analysis is done for parasites, then the deadline for obtaining such a result will vary from 3 to 9 days.
Calais analysis
In addition to the fact that the blood for worms can be donated to obtain accurate information, for the same purpose you can also pass feces for conducting a coprogram.This type of diagnosis allows you to identify helminths in feces during their active reproduction.Therefore, if you do not know how to check for worms, but want to do it yourself and immediately, you can simply contact any commercial laboratory with feces for research.By the way, the family doctor will also primarily issue a referral for such an examination in case of suspicion of helminths.
It is important to understand that if a blood test for worms allows you to identify the maximum number of parasites in the body, then the list of helminths in the study of feces looks somewhat different.
In particular, when checking for worms of feces, you can identify eggs and individuals of such helminths:
- Vlashev;
- Krivolovka;
- Pinworm;
- Ascaris;
- Non -core;
- Liver and cat biconomas;
- Strip worm;
- Pork and bull champion;
- The tape is wide;
- Fluke;
- Schistosoma and others.
It is worth knowing that such a study is not always informative, since the parasite can be at the time of passing feces in the maturation stage and is not yet ready to lay eggs.Therefore, in order to obtain a reliable result, it is advisable to take a feces analysis three with a break of 2-3 weeks.
Those who are interested in how to take tests for parasites through the study of feces should know that the feces need to be assembled in a sterile plastic container after committing the morning emptying of the intestine.You do not need to wash yourself before going to the toilet.At the same time, it is desirable to do your business not in the toilet, but in a container, devoid of particles of disinfectants or detergents.
It is important to ensure that urine and discharge from the genitals do not get into the biomaterial.You need to collect samples from different parts of feces (from the front, from the back and side).The feces assembled in a container in the amount of 2/3, it is advisable not to store, but immediately send for analysis.Since parasite eggs can live in an external environment up to 10 hours.Storage of the sample reduces the likelihood of a reliable result.
Important:The doctor should also tell about how to hand over the feces correctly when issuing a direction.
If the reader is interested in how many days can analyze this type, then the diagnostic period is much less than when analyzing blood for parasites.In most cases, the result is ready in the evening and sent to the patient’s e -mail (if the diagnosis is carried out in a commercial laboratory).The maximum deadline for obtaining the result of the coprogram is 1-2 days subject to the weekend.
Important:For the smallest patients, they often analyze enterobiosis in the form of scraping.To do this, the cutting of the baby is applied to the skin folds of the anal opening of the baby and press it well.The selected sample is glued to a special laboratory glass and sent for research.In this way, you can identify eggs of pinworms.
When is the analysis of worms required?
To take tests for worms is primarily recommended to people who can be at risk of infection to the greatest extent.
Medical practice shows that helminthic invasion is much more common in the following categories of people:
- workers who are often in contact with animals: farmers and veterinarians;
- Hunters and fishermen, as well as those who like to often go to rest on wildlife;
- People living in rural areas, where various infectious diseases often break out;
- medical workers who often have to communicate with infected patients;
- Workers of kindergartens, schools, as well as other public places.We must not forget about the cooks and people working in the field of catering, who often have to deal with raw meat, fish, vegetables and herbs, because often the products need to be tasted before their complete cooking;
- People who do not observe personal hygiene do not wash their hands before eating, and possibly the products themselves before eating;
- An ordinary city resident, who can have cockroaches or flies or other insects at home, because even ants are carriers of various helminths.
All these people must take a blood test for worms, or make a scraping of the skin, it is also possible to pass feces.The attending physician is engaged in the correct selection of the type of analysis, depending on the symptoms that appear during infection.
Symptoms can be different, consider the main ones:
- A sharp weight loss, while a person has a good appetite, and he eats more than usual.But over time, the appetite disappears, as the general condition worsens;
- the presence of itching and irritation in the anus, burning at the anus is possible;
- The pallor of the skin due to the lack of nutrients, vitamins are now not absorbed, and all beneficial vitamins and minerals are consumed by worms;
- Due to the decrease in immunity and vital tone, chronic fatigue and fatigue appears;
- the presence of problems with the gastrointestinal tract, from nausea and vomiting to pain and problems with stools, primarily indicate the need to take tests for worms in adults;
- Headaches and dizziness, which is associated with the release of toxins with worms.
If you or your loved ones have health problems and at least 2-3 signs from the list have been recorded, then there is a high risk of worms.
As statistics show, most people on the planet are infected with helminths, but do not suspect this, continuing to be treated from the consequences of helminth parasitization.Therefore, take an interest in the clinic what tests are handed over for worms, and undergo an examination to get rid of the root cause.Before asking the question of what tests to pass on worms to an adult or child, it is recommended to pay attention to the preparatory process.
Preparation for passing the analysis for worms
Blood or feces should comply with certain requirements, for which certain rules of preparation must be followed:
- A week before the tests, you can not use anthelmintic drugs, both in the dosage form and various folk remedies, since this can cause a negative result of the tests, even with the apparent presence of helminthiasis;
- Also, a week or 4-5 days before the planned contacting the clinic, you need to abandon the sorbents and laxatives, otherwise, the tests can also give a negative result;
- About 3-5 days before visiting a medical institution, you need to start taking dietary food, it is not recommended to drink carbonated drinks, consume sweet, sour, spicy and smoked meals, it is also worth abandoning fatty foods.
Thanks to such simple, but effective preparatory measures, the analysts for blood or feces will be the most accurate, which means that you can quickly begin treatment.
Analysis for ascariasis
Ascaridosis is also widespread in children and adults: up to 20% of the world's population is sick.Askarid worms, like pinworms, belong to the Nematodes group, but they look much worse: their body length can reach 30–40 centimeters.Fresh vegetables and fruits usually become the source of the disease: in the soil, the ascaride eggs can survive up to several years, getting "on the table" directly from the bed.
Symptoms of ascariasis are weakness, fatigue, itching in the anus.Askarides are able to spread throughout the body, causing liver, respiratory tract, and gall bladder lesions - in this case, secondary ones caused by organs are added to the primary signs.
The development of ascariasis can even lead to the death of the patient.
The most effective for identifying ascarides in the body is a blood test for antibodies.
It does not require special preparation, but it is advisable to refrain from eating within four hours before analysis.
Analysis for opisthorchiasis
Opisthorchiasis cause flat worms - a cat's two -eyed.The disease has a pronounced local distribution.You can get an opisthorchiasis when eating infected fish, which is an intermediate host of the parasite.Worms develop in the gallpads and ducts of the pancreas, causing infections, allergic reactions, liver diseases, side pain and fever.
The absence of timely treatment can lead to damage to the central nervous system, chronic gastritis, stomach ulcer and duodenum.
The most effective for identifying a cat bickery is a blood test for specific IgG antibodies.A reliable result can be obtained during the study from the sixth to eight week after infection.When moving to the chronic stage, the indicators may return to normal, in this case, this method will not work to determine the opisthorchiasis.
Trichinellosis analysis
Trichinellosis is caused by trichinella - helminths that enter the human body with infected meat and lard.Products in large stores are sure to check for the presence of a parasite, so private farmers, hunters and people who buy meat in unverified places usually become the victim of Trichinell.Eggs of this parasite are not able to destroy the usual heat treatment, and salt, smoking does not help.One small piece is enough for infection.
Symptoms of the disease in the first two to three weeks are allergic reactions of the body, nausea, diarrhea, vomiting.Then there is a disease of the organ in which worms developed: parasites can choose any part of the body and destroy it for many years.Ultimately, trichinellosis can lead to death of the patient or to irreversible disorders in the body.
If there is a suspicion of the presence of a trichinell, the patient is directed to a blood test for specific antibodies.With a negative result and ongoing symptoms, it is recommended to undergo a second examination in a couple of weeks: in the early stages, the disease may not be detected, high accuracy gives blood test from the second to fourth week after infection.
