Parasite analysis is the most reliable method to determine the presence of uninvited guests in the body.Currently, diagnosis can be made using blood or stool tests.So, today we will talk about how to get tested for parasites.
The threat of parasites
Parasites are organisms that use humans as a source of food and a place of residence, and are localized in the gastrointestinal tract, lungs, muscles, and joints.
If the number and size of parasites are small, their presence may go unnoticed for a long time, but parasites multiply or grow rapidly and move throughout the body during their life cycle, often leading to the development of serious health problems.
For example, roundworms that collect in the intestines can cause constipation and congestion.The cow tapeworm grows up to several meters and seriously damages the digestive system, depriving the owner of nutrients and vitamins.Echinococcus forms cysts in internal organs, including the brain, liver and lungs.Rupture of such a cyst can occur unexpectedly, after a minor injury or during an examination.The contents of the cyst may cause anaphylactic shock or collapse.Trichinella larvae feed and live in muscles, gradually destroying them.According to the WHO, parasitic diseases cause the death of approximately 14 million people worldwide every year.
Blood test for parasites
Tests for parasites are necessary for everyone without exception.If a person does not suspect the presence of worms in the body and has never complained of symptoms indicating the presence of helminths.According to the WHO, up to 100 million people are infected with protozoa every year.Almost all people living on our planet have encountered parasitic infestations during their lives.
Parasites are organisms that use humans as a food source and habitat, and are localized in the gastrointestinal tract, lungs, muscles, and joints.They can also live in the blood and even affect the eyes and brain.They can be unicellular, multicellular and protozoa (bacteria and viruses).
The most common routes of infection:
- Parasitic eggs enter the digestive system of a person through poor-quality water, if sanitary and hygienic rules are not followed, along with poorly washed vegetables and fruits, undercooked meat and fish dishes.Experience shows that eggs of several types of parasites can sometimes be found in bread lying on a store shelf.Also, some species are transmitted through fur products (echinococcosis);
- inhalation, penetration through the skin;
- through insect bites (for example, mosquitoes carry malaria);
- in contact with sick people - for example, with scabies.
Instructions for the test
A blood test for parasites is recommended for both adults and children.It is very difficult and sometimes impossible to determine the presence of unwanted "inhabitants" in the body based only on symptoms.In most cases, this is due to the non-specificity of the symptoms of the disease.
Protozoa and organisms affect humans, causing allergic manifestations, pain in the gastrointestinal tract, lethargy and weakness.As a result, you can visit an allergist for years and treat swelling and heaviness in the abdominal cavity, without suspecting that worms are to blame for your health problems.
In children, helminths can cause retardation of mental and physical development, as well as reduce resistance to infectious and somatic diseases.Often the whole family suffers, they constantly infect each other.Therefore, if there is the slightest doubt, it is necessary to undergo an examination.
One of the most informative tests is a blood test.This test identifies specific substances that indicate the presence of infestations.
What tests are needed to detect parasites?
Blood and stool tests can determine the presence of helminths in the body.Parasites that live in the intestines reproduce using eggs or whole sections, which contain large numbers of eggs that are excreted with the feces.A sick person thus becomes a distributor of parasites.Fecal analysis is performed to detect helminth eggs and allows to determine the presence of helminths and its species (pinworms, tapeworms, etc.).
Since the active life of the parasite is manifested by the release of toxic substances and sensitization of the body, characteristic changes in the blood formula can be observed in the analysis.A complete blood count helps detect elevated eosinophil levels and, less commonly, anemia.This study allows us to suspect or confirm the presence of a parasitic disease without specifying the type of parasite.
Analysis of feces is not always informative.The absence of worm eggs in the feces is a reason to exclude only some types of helminthosis.To detect other parasites, a blood test is performed for antibodies against them (echinococcus, opisthorchid, trichinella, etc.).Determining the type of parasite helps the doctor to prescribe the necessary additional examinations or choose the right treatment right away.
Tests for parasites are recommended when infection is suspected (appearance of characteristic complaints and health problems), for people living in areas with a high risk of infection, for employees of child care facilities, food industry, for family members who have been diagnosed with a parasitic disease, etc.
Timely detection and treatment of parasitism allows you to avoid dangerous complications and health problems.
The most commonly used are:
- Immunoenzyme, also called ELISA.
- Hemoscanning of blood.
- Serological analysis.
- PCR diagnostics of blood for the presence of parasites.
- Each test has its own characteristics and can be prescribed only if the attending physician considers it necessary.
Enzyme immunoassay
With its help, it is possible to identify antibodies and antigens in the blood of adults and children.That is, it shows quite reliably how many parasitic worms and their metabolic products there are.
This analysis allows not only to determine the presence of helminths in the body, but also to monitor the dynamics of treatment or diseases caused by worms.Enzyme immunoassay is often prescribed when the presence of echinococcus in tissues is suspected.
How to check for parasites
The best way to check for parasites is through a stool test.Most doctors will order a standard stool test if they suspect parasites, but such tests are not as accurate as the extensive tests used to treat functional disorders.
Standard stool tests can detect parasites or their eggs, but such tests are limited in many ways.The problem with these tests is that they are only marginally effective.They require three separate stool samples to be sent to a laboratory where a pathologist examines them under a microscope.The life cycle of parasites is unique - it allows them to be in an intermediate state between hibernation and activity.
In order to detect parasites in standard tests, the stool sample must contain a live parasite, the parasite must survive when the sample is taken to the laboratory, and then the pathologist must see the live parasite under a microscope.Although this type of test is important for some, it does not detect dormant parasites and therefore this type of stool test often gives false negative results.
A detailed analysis of feces used in the treatment of functional disorders.The broad test is much more accurate than a standard stool test because it uses polymerase chain reaction (PCR) technology to make the parasite's DNA more visible.This means that the parasite may be dead or inactive, but it will still be detected by this test.
Because this test uses PRC technology, its success does not depend on the pathologist's ability to see the parasite under a microscope.It is quite common to diagnose parasites in a patient whose standard stool analysis does not reveal the parasite.
Many people consider stool analysis to be the most reliable test for parasites.Currently, this is generally not the case.You can determine the presence of uninvited guests with just a drop of blood.To make an accurate diagnosis, you need a magnifying device and a video camera.
A blood test is considered the most informative.Currently, there are several tests that differ in their methods, but all of them are aimed at identifying parasites in the body.
Where to get tested
You can take a blood test for helminths and protozoa with reliable results in a medical center with its own clinical diagnostic laboratory.
You can take a blood test for helminths and protozoa with reliable results in a medical center with its own clinical diagnostic laboratory.The processing of the resulting material requires minimal time.
The clinics use modern technologies, which allow our specialists to conduct professional analyses, and to provide patients with the most complete information about their state of health without queues and waiting.We employ highly professional specialists in the field of parasitology who have successful experience in well-known clinics in Europe and the USA and are used by specialists in other clinics.
What parasitic diseases can be detected using tests?
Opisthorchosis
The disease is caused by the opisthorch worm, which chooses the liver, gall bladder or pancreas as a place of residence.Infection occurs after eating raw or dried fish infected with opisthorchis larvae.It manifests itself as severe pain in the epigastric region and right hypochondrium, nausea, vomiting, dizziness, weakness, headaches, enlargement of the liver and pain in it.
The patient's blood is checked for the number of eosinophils (white blood cells responsible for binding foreign proteins circulating in the blood) and for signs of anemia.
Trichinosis
Trichinosis is caused by Trichinella.It develops when eating poorly cooked or fried meat
The disease is caused by Trichinella.It develops when eating poorly cooked or fried meat.It manifests itself as a headache, muscle pain, swelling of the face (especially the eyelids), allergies and a periodic rise in temperature.
ascariasis
The roundworm can reach a length of 40 cm and lives in the intestines.Larvae can settle in the lungs, liver and heart.There are cases where these parasites come out of the mouth, nose and even ears.It can manifest itself as atopic dermatitis, neurodermatitis, allergies, chronic bronchitis, sinusitis, hepatitis, and mycoses.Also, frequent pain in the navel region, loss of appetite, dizziness, fainting and bad sleep.Infection occurs when personal hygiene is not followed and unwashed vegetables and fruits are eaten.
Toxocarosis
Toxocara helminth parasitizes humans in the form of larvae that infect the liver, lungs, heart, kidneys, brain and eyes.Fatal cases of damage to the heart and nervous system are known.It is manifested by allergic reactions, bronchial asthma, fever, cough, enlarged liver, damage to the organs of vision with the possible development of blindness.
Infection occurs through dirty hands and contaminated food.
Echinococcosis
With this type of disease, cysts formed by parasite larvae are formed in the liver, lungs and other internal organs of a person.The presence of cysts in the liver is manifested by pain in the right hypochondrium, weakness, malfunction, fatigue, decreased activity and sometimes allergic reactions.When the cyst is located in the lung, cough and shortness of breath appear.If you do not observe personal hygiene, you can get echinococcosis.
Giardiasis
Giardia are unicellular microorganisms with several pairs of flagella that live in the lumen of the human small intestine.The disease is manifested by diarrhea, nausea, vomiting, changes in the color and structure of the skin.Infection occurs as a result of consumption of food and water contaminated with Giardia cysts.
For the most complete diagnosis, it is necessary to undergo a stool test to detect helminth eggs, as well as other types of tests.If there are pains in the epigastric area, it is also recommended to consult a gastroenterologist, to check whether the stool contains Helicobacter Pylori antigen, to conduct an ultrasound of the abdominal organs and to perform a gastroscopy.
Complications of parasitic diseases
When the parasite lives or dies, toxins are released into the host's body.They can cause weakness, constant fatigue, dizziness, headache, nausea and loss of appetite.In addition, these substances provoke sensitivity of the body, which causes allergies - rash, dermatitis, bronchitis.Many parasites choose to live in the human gastrointestinal tract.While growing in the intestines, as well as during feeding, parasites damage and destroy mucosal cells and blood cells.Extensive damage to the mucous membrane can manifest as pain, nausea, disturbances in digestion and absorption of nutrients.
A large number of parasites (for example, roundworms) can mix together in a ball and cause intestinal obstruction and acute intestinal obstruction.The risk of this complication is especially high in young children because their intestinal lumen is narrower.
The parasite is so called because it does not care much about the interests of the host organism.It takes all the necessary elements from food, depriving the owner of many important nutrients - minerals and vitamins.Therefore, one of the complications of parasitic diseases is hypovitaminosis and avitaminosis, which manifests itself as a decrease in immunity, skin, nails, hair, etc.significant loss of blood cells (due to parasites feeding on them) and their insufficient formation (due to hypovitaminosis) cause anemia.A parasite like Trichinella lives in the muscles and feeds on them, causing severe muscle pain.
A parasite like Trichinella lives in the muscles and feeds on them, causing severe muscle pain.Parasites living or multiplying in the bile ducts (for example, opisthorchids) can cause obstruction of the bile ducts, which is manifested by yellowing of the skin and sclera and itching.
Parasites are a source of regular chronic damage to cells, which leads to their malignant changes and the development of cancer.
Another danger of parasites is that an infected person is often the cause of infection to other people.As a result, if one of them has a parasite, the whole family can get sick.
To improve survival, some parasites have a very complex life cycle, during which they change several hosts and exist as different life forms in each.For example, for echinococcus, it is a dead end in the human life cycle, and after entering his body, the parasite forms cysts and capsules in various organs (brain, liver, lungs).
The appearance of cysts in the brain can lead to the development of epilepsy and other neurological disorders.In addition, cysts are a source of abscess formation in internal organs.
In order to protect yourself and your loved ones from parasites, it is necessary to detect and treat parasitic diseases in time.A comprehensive examination for helminth infections helps.
How to get rid of parasites
A detailed analysis of feces can identify 17 different parasites, so when the doctor learns what pest is in the patient's body, he prescribes drugs aimed at destroying a certain type of parasite.
However, if the parasite cannot be identified, the doctor may prescribe a mixture of herbs, including caprylic acid and magnesia, barberry, Tribulus extracts, Artemisia annua, grapefruit, barberry, sea buckthorn, black walnut.
These ingredients can usually be found at the pharmacy.By promoting beneficial gut bacteria, these herbal formulas have broad-spectrum activity against the most common pathogens found in the human gastrointestinal tract.
Before starting the fight against parasites with the help of medicinal plants, it is recommended to consult a doctor, and it is worth rechecking their levels in case of previous liver diseases, excessive alcohol consumption or the previously mentioned increase in the level of liver enzymes.
If you suspect the presence of parasites living in the liver, examination and examination of the material taken is prescribed.If the test results show the presence of these parasites, then long-term treatment is carried out in a hospital setting, which does not always have a positive result.Some patients are treated for years and cannot get rid of parasites.All you had to do was eat proven fish and undergo thorough heat treatment.To prevent parasite infection, always wash your hands with running water and soap before eating, and wash fruits, vegetables and herbs thoroughly.After washing, everything should be washed with hot water.
Do not drink or boil water from unapproved sources.Boil and fry meat and fish well.Do not consume unboiled cow's milk.It is better to buy tested and pasteurized milk products in the store.Do not forget to carry out preventive deworming for your pets and treat them against fleas in time.Get rid of rodents that often live in basements.
If you suspect the presence of a parasite in your body, you should consult a doctor so that he can prescribe a detailed stool test.After all, everything starts in the gut, and the gut is the path to health.A healthy gut means a healthy person.
