Analysis for parasites is the most reliable method of determining the presence of uninvited guests in the body.Currently, the diagnosis can be made using blood or stool tests.That's why today we're going to talk about how to get tested for parasites.
Danger of parasites
Parasites are organisms that humans use as a source of food and residence and localize in the gastrointestinal tract, lungs, muscles and joints
If the number and size of parasites are small, their presence can go unnoticed for a long time, but the rapid reproduction or growth of parasites and their movement through the body during their life cycle often lead to the development of serious health problems.
For example, roundworms that accumulate in the intestines can cause constipation and constipation.The beef tapeworm grows to be several meters long and causes significant damage to the digestive tract, depriving the owner of nutrients and vitamins.Echinococcus forms cysts in internal organs, including the brain, liver, and lungs.Such a cyst can burst unexpectedly, after a minor injury or during an examination.The contents of the cyst can cause anaphylactic shock or collapse.Trichinella larvae feed on the muscles, live there and gradually destroy them.According to the WHO, parasitic diseases are responsible for approximately 14 million deaths worldwide each year.
Blood test for parasites
Tests for parasites are necessary for everyone without exception.Even 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 on our planet have been confronted with parasite infestations in the course of their lives.
Parasites are organisms that humans use as a source of food and residence and colonize 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 when sanitary and hygienic rules are not observed.As practice shows, eggs of various types of parasites can sometimes be found on bread lying on a store shelf.Some species are also transmitted through fur products (echinococcosis);
- Inhalation, penetration through skin;
- through insect bites (for example, mosquitoes transmit malaria);
- in contact with sick people - for example with scabies.
Notes on testing
A blood test for parasites is recommended for both adults and children.It is very difficult and sometimes impossible to detect the presence of unwanted “residents” in the body based on symptoms alone.This is because in most cases the symptoms of the disease are not specific.
Protozoa and organisms affect humans, causing allergic manifestations, pain in the gastrointestinal tract, lethargy and weakness.This will allow you to see an allergist for years and treat bloating and heaviness in your stomach without suspecting that worms are to blame for your health problems.
In children, helminths can cause delayed mental and physical development and reduce resistance to infectious and physical diseases.Very often the whole family suffers and constantly infects each other.Therefore, it is necessary to get tested if there is the slightest suspicion.
One of the most informative tests is a blood test.This test identifies certain substances that indicate the presence of an infestation.
What tests are needed to detect parasites?
Blood and stool tests can detect the presence of helminths in the body.Parasites living in the intestine reproduce via eggs or entire compartments with large numbers of eggs that are excreted in the stool.This is how a sick person becomes a distributor of parasites.A fecal analysis is carried out to detect worm eggs and allows determining the presence of a worm and its type (pinworms, tapeworms, etc.).
Since the active life of the parasite is expressed in 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 elevated eosinophils 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 meaningful.The absence of worm eggs in the feces gives reason to exclude only some types of helminthiasis.To detect other parasites, a blood test is carried out for antibodies against them (echinococci, opisthorchids, trichinae, etc.).Determining the type of parasite helps the doctor prescribe the necessary additional examinations or immediately select the right treatment.
Tests for parasites can and should be carried out in cases of suspected infection (occurrence of characteristic complaints and health problems), in people living in areas with an increased risk of infection, in employees of childcare institutions, in the food industry, in family members who have been diagnosed with a parasitic disease, etc.
By detecting and treating parasitosis in a timely manner, you can 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 be prescribed by the attending physician only if he considers it necessary.
Enzyme immunoassay
With its help it is possible to identify antibodies and antigens in the blood of adults and children.This means that 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 track the dynamics of treatment or diseases caused by worms.Most often, an enzyme immunoassay is prescribed if the presence of echinococci in the tissue is suspected.
How to check if parasites are present
The best way to check for parasites is with a stool exam.Most doctors prescribe a standard stool test when parasites are suspected, but this is not as accurate as the extensive tests used in medicine for dysfunction.
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 partially effective.You will need three separate stool samples to be sent to a laboratory where they will be examined under a microscope by a pathologist.The life cycle of parasites is unique – it allows them to be in an intermediate state between hibernation and functionality.
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 look at the live parasite under a microscope.Although this type of examination may be important for some, it does not detect dormant parasites, and for this reason, this type of stool examination often produces false negative results.
Detailed stool analysis for the treatment of functional disorders.The comprehensive test is much more accurate than a standard stool test because it uses polymerase chain reaction (PCR) technology to better visualize the parasite's DNA.This means that the parasite may be dead or dormant, but will still be detected with this test.
Because this test uses PRC technology, its success does not depend on the pathologist's ability to detect the parasite under the 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 a drop of blood.For an accurate diagnosis, you will need a magnifying device and a video camera.
A blood test is considered the most informative.Today, several tests are carried out, differing in their methods, but all of them are aimed at identifying parasites in the body.
Where can you get tested?
In a medical center that has its own clinical diagnostic laboratory, you can have a blood test for helminths and protozoa with reliable results
In a medical center that has its own clinical diagnostic laboratory, you can have a blood test for helminths and protozoa with reliable results.Processing the resulting material takes minimal time.
The clinics use modern technologies that allow our specialists to conduct professional analyzes and provide patients with the most complete information about their health status without queues and waiting times.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.
Which parasitic diseases can be detected with 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 infected with Opisthorchis larvae.It is manifested by severe pain in the upper abdomen and the right hypochondrium, nausea, vomiting, dizziness, weakness, headache, enlarged liver and its pain.
The patient's blood is examined 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 trichinae.Occurs when eating poorly cooked or fried meat
The disease is caused by trichinae.Occurs when eating poorly cooked or fried meat.It is manifested by headaches, muscle pain, swelling of the face (especially the eyelids), allergies and periodic increases in temperature.
Ascariasis
The roundworm can reach a length of 40 cm and lives in the intestines.The larvae can settle in the lungs, liver and heart.There are cases where these parasites emerge through the mouth, nose or even ears.It can manifest itself as atopic dermatitis, neurodermatitis, allergies, chronic bronchitis, sinusitis, hepatitis, mycoses.This often includes pain in the navel area, loss of appetite, dizziness, fainting and poor sleep.Infection occurs when personal hygiene rules are not followed and when unwashed vegetables and fruits are eaten.
Toxocariosis
The helminth Toxocara parasitizes humans in the form of larvae that colonize the liver, lungs, heart, kidneys, brain and eyes.There are known cases of fatal 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
In 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, reduced activity and sometimes allergic reactions.If the cyst is in the lungs, coughing and shortness of breath occur.If you do not pay attention to personal hygiene, you can become infected with echinococcosis.
Giardiasis
Giardia are unicellular microorganisms with multiple pairs of flagella that live in the lumen of the human small intestine.The disease manifests itself as diarrhea, nausea, vomiting and changes in skin color and structure.Infection occurs through consumption of food and water contaminated with Giardia cysts.
For the most complete diagnosis, you may need to do a stool test to detect worm eggs and undergo other types of tests.If there is pain in the upper abdomen, it is also recommended to visit a gastroenterologist, test the stool for Helicobacter pilori antigen, do an ultrasound scan of the abdominal organs and have 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, headaches, nausea and loss of appetite.In addition, these substances provoke sensitization of the body, which triggers allergies - rash, dermatitis, bronchitis.Many parasites live in the human gastrointestinal tract.When strengthening in the intestines and during food intake, parasites damage and destroy mucous membrane cells and blood cells.Large-scale damage to the mucous membrane can manifest itself in pain, nausea, and digestive and nutrient absorption disorders.
A large number of parasites (for example, roundworms) intertwined into a ball can cause intestinal obstruction and acute intestinal obstruction.The risk of this complication is particularly high in young children because their intestinal lumen is narrower.
The parasite is so named because it has little concern for the interests of the host organism.It deprives the food of all the necessary elements and deprives the owner of many vital nutrients - minerals and vitamins.Therefore, one of the consequences of parasitic diseases is hypovitaminosis and avitaminosis, which can manifest itself in reduced immunity, deterioration of the skin, nails, hair, etc.Significant loss of blood cells (due to parasite feeding) and their insufficient formation (due to hypovitaminosis) leads to 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 that live or reproduce in the bile ducts (e.g. opisthorchid) can cause obstruction of the bile ducts, manifested by jaundice of the skin and sclera and itching.
Parasites are a source of regular chronic cell damage, leading to malignant changes and the development of cancer.
Another danger of parasites is that in most cases an infected person becomes the cause of infection for other people.As a result, all family members can become ill if one of them has the parasite.
To improve survival, some parasites undergo a very complex life cycle in which they change multiple hosts and exist in each as a different life form.For example, for echinococci, humans are a dead end in the life cycle and, penetrating their 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 a timely manner.A comprehensive examination for helminth infections helps.
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 drugs aimed at destroying a specific type of parasite.
However, if the parasite cannot be identified, the doctor may 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 are usually available at the pharmacy.By promoting beneficial intestinal bacteria, these herbal formulas provide broad spectrum activity against the most common pathogens in the human gastrointestinal tract.
Before starting to combat parasites with medicinal herbs, it is advisable to consult a doctor.If you have a history of liver disease, excessive alcohol consumption, or a previously detected increase in liver enzyme levels, it is worth checking your levels again.
If there is suspicion of the presence of parasites living in the liver, probing and examination of the sampled material is prescribed.If the test results show the presence of these parasites, long-term treatment in the hospital is carried out, which does not always give a positive result.Some patients are treated for years and cannot get rid of the 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 with running water and soap before eating, and wash fruits, vegetables, and herbs thoroughly.After washing, everything must be poured with boiling water.
Do not drink water from untested sources or boil it.Cook and fry meat and fish thoroughly.Do not consume uncooked cow's milk.It is better to buy tested and pasteurized dairy products in the store.Don't forget to deworm and treat your pets for fleas in a timely manner.Eliminate 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 examination.After all, everything starts in the gut, and the gut is the path to health.A healthy gut means a healthy person.
