Most parasitic infections today help to identify a well -assigned worm analysis.The diagnosis is made in specialized laboratories using the latest equipment and reagents.
Moreover, each parasite analysis has a number of certain requirements for its implementation.In which tests should be delivered for worms and how to do it correctly, and also how to interpret them correctly, we understand below.
Types of Tests for Identifying Worms
There are several types of tests, the set of results of which can indicate a particular parasitic occupation.However, it should be remembered that only the attending doctor can decipher the results and make a diagnosis.
Blood test
One of the most reliable and informative methods (with an accuracy of 93%) for diagnosing in helminths is a blood test for parasites.In the circles of doctors, such a study is called ELISA (immuno -functioning analysis for parasites in the human body).The study allows you to identify in the blood serum the presence of antibodies that are 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 occupation in the early stages, when the helminth is not yet capable of reproducing and does not cease eggs that can be detected during a coprogram (special feces analysis for an egg).
It is important to understand that the use of such a blood test for parasites can be identified the following parasitic infections:
- Opisthorchiasis;
- Lambliosis;
- Enterobiosis;
- Ascaridosis;
- Toxoplasmosis;
- Toxocarosis;
- Trichinellosis and others.
Blood in the parasites is taken from a morning vein on an empty stomach.At the same time, before conducting the study, it is worth making preparatory measures.
In particular, to perform a blood test for parasites, you must adhere to such rules:
- Three days before the diagnosis, do not eat greasy, fried, complex dishes.Food should be simple and easy to digest;
- Three days before the study, you should abandon alcohol and any medicine;
- The day before you donate blood to worms, you should be limited to excessive physical and psycho -emotional stress;
- For at least 3-4 hours, you should refuse smoking.
Important:Performing a blood test for parasites in accordance with all of these rules allows you to get the most accurate result and eliminate the attraction of a positive false result.If the reader is interested in how long the analysis of the parasites takes place, then the deadline for obtaining such a result will vary from 3 to 9 days.
Calais's analysis
In addition to the fact that blood for worms can be donated to obtain accurate information, for the same purpose you can also pass the feces for performing a coprogram.This type of diagnosis allows you to identify poisons in the feces during their active reproduction.Therefore, if you do not know how to check the worms, but you want to do it yourself and immediately, you can simply contact any trading laboratory with research feces.By the way, the family doctor will also issue a reference 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 feces worms, you can identify eggs and individuals of such helminths:
- Vlashev;
- Krivolovka;
- Pinw worm;
- Ascaris;
- Not -kore;
- Liver and cat biconomas;
- Stripe worm;
- Champion of pig and bull;
- The tape is wide;
- Fluke;
- Schistosoma and others.
It is worth knowing that such a study is not always informative, as the parasite may be at the time of passing the feces at the maturity stage and is still not ready to lay eggs.Therefore, to get a reliable result, it is advisable to get a three-week feces analysis with a 2-3 week break.
Those who are interested in how to do tests for parasites through the study of feces should know that the feces should be collected in a sterile plastic container after performing the intestinal breakfast.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, with no particles of disinfectants or cleaners.
It is important to ensure that urine and discharge from the genitals do not enter the biomaterial.You need to collect samples from different parts of the feces (from front, back and anna).The feces collected in a container in the amount of 2/3, it is advisable not to save, but to immediately send for analysis.Since parasite eggs can live in an external environment for up to 10 hours.Sample storage reduces the possibility of a reliable result.
Important:The doctor should also show how to deliver the feces correctly when issuing a direction.
If the reader is interested in how many days he 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 is sent to the patient's -mail (if the diagnosis is performed in a trade lab).The maximum deadline for obtaining the Koprogram result is 1-2 days undergoing the weekend.
Important:For younger patients, they often analyze enterobiosis in the form of scrap.To do this, cutting the baby is applied to the anal opening skin of the baby and press well.The selected sample is glued to a separate laboratory glass and sent for search.This way, you can identify the worm eggs.
When is worm analysis required?
To take tests for worms, it is mainly recommended for people who can risk infection to a greater extent.
Medical practice shows that helminthic occupation 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 want to go often rest in wild life;
- People living in rural areas, where various infectious diseases often erupt;
- Medical workers who often need to communicate with infected patients;
- Workers of kindergartens, schools, and other public places.We must not forget about chefs and people working in the field of catering, who often have to deal with raw meat, fish, vegetables and herbs, because products often have to be enjoyed before cooking them;
- People who do not observe personal hygiene do not wash their hands before they eat, and perhaps the products themselves before they eat;
- An ordinary resident of the city, which may have cockroaches or other flies or insects at home because even ants are carriers of different helminths.
All of these people have to do a blood test for worms, or make a scrap of skin, it is also possible to pass the feces.The attending doctor is engaged in the correct choice of the type of analysis, depending on the symptoms that occur during the infection.
Symptoms may be different, consider the main ones:
- A sharp loss in weight, while a person has a good appetite, and he eats more than usual.But over time, the appetite disappears, while the general situation deteriorates;
- The presence of itching and irritation in the anus, burning in the anus is possible;
- Dening the skin due to lack of nutrients, vitamins are now not absorbed, and all useful vitamins and minerals are consumed by worms;
- Due to the decrease in immunity and life tone, chronic fatigue and fatigue occur;
- The presence of problems with the gastrointestinal tract, from vomiting and vomiting to pain and problems with excrement, largely indicate the need to take tests for worms in adults;
- Headache 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 are recorded, then there is a high risk of worms.
As statistics show, most people on the planet are infected with helminths, but do not doubt this, continuing to be treated by the consequences of helminth parasitization.Therefore, be interested in the clinic which tests are given to worms and undergo an examination to get rid of the root cause.Before you ask which tests to pass the worms to an adult or a child, it is recommended to pay attention to the preparatory process.
Preparation for the passage of worms analysis
Blood or feces must match certain requirements, for which certain preparation rules must be followed:
- One week before the tests, you cannot use anthelmintic medicines, both in the form of dosage and in various popular remedies, as this can cause a negative result of tests, even with the visible presence of helminthiasis;
- Also, a week or 4-5 days before contacting the clinic, you should abandon the sorbents and laxatives, otherwise, the tests can also give a negative result;
- About 3-5 days before visiting a medical institution, you should start getting dietary food, it is not recommended to drink carbonated drinks, consume sweet, dry, spicy and smoked foods, it is also worth abandoning fatty foods.
Thanks to such simple but effective preparatory measures, blood analysts or feces will be more accurate, which means you can quickly start treatment.
Analysis for Askariasis
Ascaridosis is also widespread in children and adults: up to 20% of the population in the world is ill.Ascarid 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, ascarid eggs can survive up to several years, taking "on the table" directly from the bed.
Symptoms of ascariasis are weakness, fatigue, itching in the anus.Ascarides are able to spread throughout the body, causing the liver, respiratory tract and gall bladder lesions - in this case, the secondary ones caused by the organs are added to the primary signs.
The development of ascariasis can even lead to the patient's death.
The most effective for identifying ascarids 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 the analysis.
Analysis for opisthorchiasis
Opisthorchiasis cause flat worms - two cats of a cat.The disease has a pronounced local distribution.You can get an opisthorchiasis when eating infected fish, which is an intermediate parasite host.Worms develop in the gallbladder and pancreatic ducts, causing infections, allergic reactions, liver disease, side pain and fever.
Lack of timely treatment can lead to damage to the central nervous system, chronic gastritis, gastric 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 while studying from sixth to eight weeks after infection.When switching to the chronic phase, indicators can return to normal, in this case, this method will not work to determine opistrchiasis.
Trichinellosis analysis
Trichinellosis is caused by Trichinella - helminths entering the human body with meat and infected bedding.Products in large stores are sure to control the presence of a parasite, so private farmers, hunters and people who buy meat in unproven places usually become victims of trichinell.Eggs of this parasite are unable to destroy the usual heat treatment and salt, smoking does not help.A small part is enough for infection.
Symptoms of the disease in the first two to three weeks are allergic reactions to the body, nausea, diarrhea, vomiting.Then there is an organ disease in which worms develop: parasites can choose any part of the body and destroy it for many years.After all, trichinellosis can lead to patient death or irreversible disorders in the body.
If there is a doubt about the presence of a trichinell, the patient is directed to a blood test for specific antibodies.With a negative result and persistent symptoms, it is recommended to undergo a second examination within two weeks: in the early stages, the disease may not be detected, high accuracy gives blood test from the second week to fourth after infection.
