Parasites are microorganisms that live and feed on other organisms.Parasites often harm the host.People often divide parasites into species such as animal parasites and plant parasites.Parasites include protozoa, helminths, arachnids, insects, and others.Plant parasites include bacteria, fungi, some higher plants, and others.
Viruses are also parasites.In most cases, to live, the parasite needs to change two or three hosts, which exhausts and weakens the body.Often leads to the death of the owner.Most parasites are the causative agents of many human diseases.In medical terminology, parasites include any organism that leads a parasitic lifestyle.The exceptions are bacteria, viruses and fungi.
Diagnosis of parasites in humans
There are several human diseases caused by parasites such as protozoa, parasitic worms, arthropods and pathogenic microorganisms.Protozoan parasites include amoeba, leishmania, lamblia, plasmodium, trypanosomes, balantids, pneumocystis, toxoplasmia and others.To parasites - helminths.Arthropods include insects and mites.And disease-causing microorganisms include bacteria and spirochetes parasitic on ticks, fleas, lice, pathogenic fungi and viruses.
The main goal of parasites is to hide their existence.That is, they live undetected in the host's body.Testing for parasites includes observing their release (amoebae, segments, worms, pinworms) or the reproductive products of the parasites (eggs, protozoan cysts).Diagnosis is made on stool, urine, sputum or human body tissue (blood and lymph nodes).
Let's highlight a list of studies used for this:
- concurrent histology program;
- histological analysis;
- immunoassay (serum);
- microscopy (blood scan);
- electroacupuncture method (ART - plantar resonance test).
Analysis by histological coprogramming involves the diagnosis of thin sections of stool samples using an optical system.It helps to clearly identify the parts of the helminth's body, their eggs and the membrane (cuticle) of the larvae.So, helminthiasis was discovered.An additional feature of this method is the identification of the type of parasite found.
More effective is a serological test to detect antibodies to helminths.This method is also known as immunoassay (serology).The essence of the test is the use of various sets of reagents and chemical markers.They are used to identify certain antibodies and parasite antigens in human blood.Immunoassays are performed only in medical laboratories.
Microscopic analysis is based on the use of dark-field, fluorescence, and electron microscopy.This diagnostic allows the study of living or fixed microscopic objects, as well as cellular and subcellular structures.
The electroacupuncture method is based on the use of special devices to determine basic data about the human health condition.This method tests different areas of the skin.
Histological analysis is a common method of examining stool for the presence of parasites.In most cases, it is used to determine helminth infection in human biological material.Can be performed on adults and children.
Blood scan (blood test) helps determine the state of the main components of the blood and the purity of the plasma.When testing for parasites based on this method is performed, the blood is not processed (i.e., not dried or stained).Its study is carried out using a microscope, connected to a video camera.Next, the material sample under study is magnified under a microscope 1800-2000 times.At this time, the screen will broadcast the resulting image, and also provide the opportunity to take photos or record video.Blood scans allow you to collect data on the state and activity of the immune system, as well as determine the presence of bacteria, fungi and helminth larvae.
VRT (plant resonance test) is based on the phenomenon of biological resonance formed between the drug and the human body.Such a drug acts as a carrier of information about the frequency of different types of parasites.In 1989, all the frequency data of different parasites, fungi and viruses were discovered and recorded.This type of research provides the opportunity to evaluate a person's condition at a certain time.That is, to determine the degree of disruption of the immune system, as well as the amount of viruses and bacteria on the human body, remove toxins, reduce the body's reaction to various antigens and allergens, etc.
In the laboratory where analysis using the ART method is performed, special attention is paid to determining the level of eosinophils.Their overestimated index indicates the presence of allergic reactions caused by parasitic infections.Eosinophils are a type of white blood cell that can detoxify bacteria.They participate in allergic processes in the human body and can be stained with acidic dyes.In other words, eosinophils are a marker of parasitic invasion in the normal immune state of humans.
Parasite analysis - which is better?
There are many types of tests, and which one is best will be determined by the attending physician.The most commonly used tests are blood and stool tests to detect different types of parasites.Among the blood tests for parasites, the following types can be distinguished:
- blood test for lamblia;
- blood test for opisthorchiasis pathogens (detects IgG antibodies);
- blood test for echinococcus pathogens;
- Blood test to detect Toxocara canis pathogens;
- blood test for trichinosis pathogens;
- Blood test for roundworm pathogens.
The raw material for researching all of the above methods is blood taken from veins.
The research material to identify helminths is feces.Because it's more frequent and easier to detect them there.
Who needs to be tested?
A blood test for parasites is offered to patients who complain of decreased overall health.As is known, there are hundreds of parasitic families on the human body.Many of them produce toxins that cause blood poisoning.Some reduce nutrient intake.At the same time, it is difficult to identify diseases that occur due to the vital activity of parasites.Because the symptoms are similar to the manifestations of many diseases.Blood tests help determine the amount of specific antibodies and immunoglobulins in the human body.They are the ones who act as parasitic signs.
In many cases, blood diagnosis is additionally carried out using the PCR method (polymerase chain reaction).This study is considered effective and reliable.Its main advantage is that it can identify many diseases at a time when other diagnostic methods are powerless.
Blood tests for parasites should also be done in preparation for vaccination, during pregnancy and after completing a course of anti-parasitic treatment.This analysis must be performed several times (immediately after treatment and after one to three months).
