Analysis for parasites is the most reliable way 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.
Danger of parasites
Parasites are organisms that use humans as a source of food and place of residence, localizing in the gastrointestinal tract, lungs, muscles, joints
If the number and size of parasites are small, their presence may go unnoticed for a long time, but the rapid reproduction or growth of parasites and their movement throughout the body during their life cycle often causes the development of serious health problems.
For example, roundworms that accumulate in the intestines can cause constipation and obstruction.Bovine tapeworm grows up to several meters in length and seriously damages the digestive tract, depriving the owner of nutrients and vitamins.Echinococcus forms cysts in internal organs, including the brain, liver, and lungs.Rupture of such a cyst may occur unexpectedly, after a minor injury or during an examination.The contents of the cyst can cause anaphylactic shock or collapse.Trichinella larvae feed and live in the muscles, gradually destroying them.According to WHO, parasitic diseases account for about 14 million deaths worldwide per year.
Blood test for parasites
Tests for parasites are necessary for everyone, without exception.Even in the case when 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 WHO, up to 100 million people a year are infected with protozoa every year.During their lives, almost all people living on our planet have encountered parasitic infestations.
Parasites are organisms that use humans as a source of food and place of residence, localizing 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 protozoan (bacteria and viruses).
The most common routes of infection:
- Parasite eggs enter the human digestive tract along with poorly washed vegetables and fruits, undercooked meat and fish dishes, through poor-quality water, and if sanitary and hygienic rules are not observed.As practice shows, eggs of several types of parasites can sometimes be found on bread that lies 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.
Indications for testing
A blood test for parasites is recommended for both adults and children.It is very difficult, and sometimes impossible, to identify the presence of unwanted “residents” in the body based on symptoms alone.This is due to the fact that the symptoms of diseases in most cases are not specific.
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 bloating and heaviness in the abdomen, not suspecting that worms are to blame for your health problems.
In children, helminths can cause delayed mental and physical development, as well as reduce resistance to infectious and somatic diseases.Very often the whole family suffers, constantly infecting each other.Therefore, if the slightest suspicion arises, it is necessary to get tested.
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 detect the presence of helminths in the body.Parasites living in the intestines reproduce using eggs or entire compartments with large numbers of eggs, which are excreted along with the stool.This is how a sick person becomes a distributor of parasites.Fecal analysis is carried out to detect helminth eggs and allows you to determine the presence of a helminth and its type (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 seen in the analysis.A complete blood count helps detect increased eosinophil levels and, less commonly, anemia.This study allows you to suspect or confirm the presence of a parasitic disease without specifying the type of parasite.
Stool analysis is not always informative.The absence of worm eggs in feces gives reason to exclude only some types of helminthiasis.To detect other parasites, a blood test is performed for antibodies to them (echinococcus, opisthorchid, trichinella, etc.).Determining the type of parasite helps the doctor prescribe the necessary additional examinations or immediately select the correct treatment.
Tests for parasites can and should be taken if there is a suspicion of infection (the appearance of characteristic complaints and health problems), for those who live in areas with an increased risk of infection, for employees of child care institutions, the food industry, for family members in whom a parasitic disease has been detected, etc.
Timely detection and treatment of parasitosis allows you to avoid threatening complications and health problems.
The most commonly used are the following:
- Immunoenzyme, it is 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 only be prescribed by the attending physician if he deems 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 trace the dynamics of treatment or diseases that were caused by worms.Most often, enzyme immunoassay is prescribed when there is a suspicion of the presence of echinococcus in tissues.
How to check for parasites
The best way to check for parasites is to have a stool test.Most doctors, if parasites are suspected, will prescribe a standard stool test, but such tests are not as accurate as the extensive ones used in the medicine of 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 that are 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 functioning.
To detect parasites in standard tests, a stool sample must contain a live parasite, the parasite must remain alive while the sample is taken to the laboratory, and then a pathologist must see the live parasite under a microscope.While this type of testing may be important for some, it does not detect dormant parasites, and for this reason, this type of stool testing often gives false negative results.
Detailed stool analysis used in the medicine of functional disorders.The extensive 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 could be dead or dormant, 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 a parasite in a patient whose standard stool analysis did not reveal the pest.
Many people consider stool analysis to be the most reliable test for parasites.Currently this is not the case at all.You can determine the presence of uninvited guests with just one drop of blood.To make an accurate diagnosis, you will need a magnifying device and a video camera.
A blood test is considered the most informative.Nowadays several tests are carried out, which 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 at a medical center that has its own clinical diagnostic laboratory
You can take a blood test for helminths and protozoa with reliable results at a medical center that has its own clinical diagnostic laboratory.Processing the resulting material takes minimal time.
The clinics use modern technologies, which allow our specialists to carry out professional analysis, and patients to receive the most complete information about their health status without queues or 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 whose work is used by specialists from other clinics.
What parasitic diseases can be detected using tests?
Opisthorchiasis
The disease is caused by the opisthorchis worm, which chooses the human liver, gallbladder or pancreas as its habitat.Infection occurs after eating raw or dried fish that is infected with opisthorchis larvae.It manifests itself as severe pain in the epigastric region and in the right hypochondrium, nausea, vomiting, dizziness, weakness, headaches, enlarged liver and its soreness.
The patient's blood is examined for the number of eosinophils (white blood cells responsible for binding foreign protein circulating in the blood) and signs of anemia.
Trichinosis
Trichinosis is caused by Trichinella.Develops when eating poorly cooked or fried meat
The disease is caused by Trichinella.Develops when eating poorly cooked or fried meat.It manifests itself as headache, muscle pain, swelling of the face (especially eyelids), allergies and periodic increases in temperature.
Ascariasis
The roundworm worm can reach 40 cm in length and lives in the intestines.The larvae can settle in the lungs, liver, and heart.There are cases where these parasites come out through the mouth, nose or even ears.It can manifest itself as atopic dermatitis, neurodermatitis, allergies, chronic bronchitis, sinusitis, hepatitis, mycoses.And also frequent pain in the navel area, loss of appetite, dizziness, fainting, and poor sleep.Infection occurs when personal hygiene rules are not observed and when eating unwashed vegetables and fruits.
Toxocariasis
The helminth Toxocara parasitizes humans in the form of larvae that occupy the liver, lungs, heart, kidneys, brain, and eyes.There are known fatal cases of damage to the heart and nervous system.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 from parasite larvae form 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, malaise, fatigue, decreased activity, and sometimes allergic reactions.When the cyst is located in the lung, coughing and shortness of breath appear.You can become infected with echinococcosis if you do not maintain personal hygiene.
Giardiasis
Giardia are single-celled 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 color and structure of the skin.Infection occurs through consumption of food and water contaminated with Giardia cysts.
For the most complete diagnosis, you may need to take a stool test to detect helminth eggs, as well as undergo other types of tests.If you have pain in the epigastric region, it is also advisable to consult a gastroenterologist, test your stool for Helicobacter Pilori antigen, perform an ultrasound of the abdominal organs, and do a gastroscopy.
Complications of parasitic diseases
When the parasite lives or dies, toxic substances 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 sensitization of the body, which causes allergies - rash, dermatitis, bronchitis.Many parasites choose to live in the human gastrointestinal tract.When strengthening in the intestines, as well as feeding, parasites damage and destroy mucous membrane cells and blood cells.Extensive damage to the mucous membrane can manifest itself as pain, nausea, disturbances in digestion and absorption of nutrients.
A large number of parasites (for example, roundworms), intertwined in a ball, can cause intestinal blockage 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 essential nutrients - minerals and vitamins.Therefore, one of the consequences of parasitic diseases is hypovitaminosis and avitaminosis, which can manifest itself as a decrease in immunity, deterioration of the skin, nails, hair, etc. Significant loss of blood cells (due to the parasite feeding on them) and their insufficient formation (due to hypovitaminosis) leads to anemia.A parasite such as Trichinella lives in and feeds on muscles, which causes severe muscle pain.
A parasite such as Trichinella lives in the muscles and feeds on them, which causes severe muscle pain.Parasites that live or reproduce in the bile ducts (for example, opisthorchid) can cause blockage of the bile ducts, which is manifested by jaundice of the skin and sclera, and itching.
Parasites are a source of regular chronic damage to cells, which provokes their malignant changes and the development of cancer.
Another danger of parasites is that an infected person in most cases becomes the cause of infection to other people.As a result, all family members can become ill if one of them has the parasite.
To improve survival, some parasites have a very complex life cycle, during which they change several hosts and exist in each as different life forms.For echinococcus, for example, a person is a dead end in the life cycle and, upon entering his body, the parasite forms cysts and capsules in various organs (brain, liver, lungs).
The appearance of cysts in the brain can cause the development of epilepsy and other neurological disorders.In addition, cysts are a source of abscess formation in internal organs.
To protect yourself and your loved ones from parasites, it is necessary to promptly identify and treat parasitic diseases.A comprehensive examination for helminth infections helps with this.
How to get rid of parasites
A detailed stool analysis can identify 17 different parasites, so when the doctor finds out which pest is in the patient’s body, he prescribes medications that are aimed at destroying a specific type of parasite.
However, if the parasite cannot be identified, the doctor can prescribe the patient a mixture of medicinal herbs, including magnesia with caprylic acid, barberine, extracts of Tribulus, Artemisia annua, grapefruit, barberry, bearberry, and black walnut.
These ingredients can usually be found at the pharmacy.By promoting beneficial intestinal bacteria, these herbal formulas provide a broad spectrum of action against the most common pathogens found in the human gastrointestinal tract.
Before starting to fight parasites with the help of medicinal herbs, it is recommended to consult a doctor, and in case of previous liver disease, excessive alcohol consumption, or a previously noted increase in the level of liver enzymes, it is worth checking their levels again.
If the presence of parasites living in the liver is suspected, probing and testing 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 lead to 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 subject it to thorough heat treatment.To prevent parasite infection, always wash your hands before eating with running water and soap, and thoroughly wash fruits, vegetables and herbs.After washing, everything needs to be doused with boiling water.
Do not drink water from unverified sources or boil it.Thoroughly boil and fry meat and fish.Do not consume unboiled milk from the cow.It is better to buy tested and pasteurized dairy products in the store.Don’t forget to carry out preventive deworming for your pets and treat them for fleas on time.Get rid of rodents, which 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, it all starts in the intestines, and the intestines are the path to health.A healthy intestine means a healthy person.
