In the human body, many types of helminths can become parasites, so there are various tests to detect them. Each diagnostic event has its own percentage of reliability and is distinguished by certain performance characteristics.
In the human body, many types of helminths can become parasites, so there are various tests to detect them. Each diagnostic event has its own percentage of reliability and is distinguished by certain performance characteristics.
Fortunately, unique techniques have been developed to detect parasite infestation at an early stage and begin treatment in a timely manner.
What tests need to be passed to detect worms?
To determine the presence of parasites, one analysis is not always sufficient, because at different stages of development, worms manifest themselves in their own way.
The main types of analysis are distinguished:
- Prevention. Allow timely detection of helminthiasis. This can be done, even without typical symptoms. It is recommended to conduct a study annually.
- Barriers. Reduce the risk of parasite spread among the population. It is considered mandatory when obtaining a medical book.
- On the doctor's instructions. Analysis is given if there are characteristic signs of helminthic invasion: nausea, itching in the anus, pain in the abdomen and fatigue.
To determine the presence of worms accurately, you need to pass several tests. In addition, some of them passed several times.
Fecal analysis for parasites
Stool analysis is the simplest analysis performed at any district clinic. The results showed the presence of worm eggs in the feces. In it there are eggs of helminths.
Mature individuals can lay thousands of eggs each day. Some of it spreads through the blood to the rest of the body. But, fortunately, most of it comes out naturally.
For a reliable analysis, it is necessary to:
- You have to pass up to 3 times. This is because the risk of swallowing an egg by a healthy person is high, although this does not mean he or she will continue to be infected.
- Cal is given at intervals of 7 days.
- Feces are taken from different sites.
No need to collect material in the morning, this can be done in the evening, but it can be stored no more than a day and in a cool place.
If a large number of eggs are detected during the study, other analysis is not required.
Complete blood count to detect worms
Such studies are known to everyone since childhood. Basically, blood is taken from fingers, but sometimes from veins. Research will quickly determine the cause of any disease.
Usually, a person does not suspect that he or she has worms. Therefore, it is important for the doctor to know about the symptoms that characterize the infection.
This analysis is capable of:
- Determine the cause of the symptoms.
- Detects the presence of parasites in the blood.
- Confirm the presence of other pathologies.
There is a misconception that helminths only live in the gastrointestinal tract. In fact, many species, after penetrating the stomach, then seep into the bloodstream and spread throughout the body. This is not without serious consequences. Parasites leave traces, which are revealed by doctors in the blood.
Haemotest
Finding information about this study is not easy, and the term itself is not familiar to many. In fact, for patients, this is a procedure for donating blood for general analysis. Differences in the laboratory study itself.
Hemotest tasks:
- Determination of immunity of any product by the body.
- What is their reaction.
Basically, the study was prescribed by a physician. Hemotest is able to detect parasites that cannot be detected in other ways. This study is considered the most reliable.
Various manipulations are performed on the blood taken from the patient. It is influenced by biological and chemical substances, observing the reaction. It is different, and some indicate the presence of helminths.
Such tests are quite complicated and are not conducted in every clinic. The result is known after 2-5 days. With the presence of parasites, the test will give a positive reaction.
PCR analysis for worm detection
This diagnosis is considered an accurate and modern research method. PCR analysis is able to detect the presence of bacteria, intracellular parasites and viruses. Blood and other body fluids were taken for analysis. If the presence of worms is suspected, then feces are used for research.
Detection of even a few fragments of parasitic DNA in the biomaterial indicates helminthic invasion. PCR analysis is relatively simple, the results are known after a few hours. This is facilitated by the use of special equipment. With this test, you can not conduct a lot of additional research, but quickly get the desired results.
Unfortunately, not every clinic has such equipment, and the cost of this analysis is quite high.
ELISA blood test for worm detection
The most popular and reliable analysis today, experts call enzyme immunoassay for parasites.
The main purpose of this high -precision laboratory method is to detect antibodies to certain types of parasites in the blood. Immunoglobulins (also called antibodies) are a natural response of the immune system, and are intended to neutralize negative agents.
Enzyme -linked immunosorbent assay (ELISA) shows changes in antibodies in the blood. This study is good for identifying parasites.
It is divided into 2 levels:
- immune system response. Can bind molecules, microorganisms and cell elements for detection.
- enzymatic reactions. You can visually evaluate the results of the reaction.
Serological blood tests
With the help of this laboratory method, infectious diseases are detected, as well as their developmental phases.
This test allows:
- Determine the patient's immune status. When infected with parasites, the immune system becomes significantly weakened.
- Detects the presence in the blood of bacteria that cause decreased immunity.
By the way, this study is used to determine blood type.
Giardia blood test
This analysis is considered to be of the highest quality. It consists of an enzyme immunoassay. Analysis determines the density of antibodies to worms of a particular species.
When infected, IgM antibodies appear in the blood, and after 2 weeks - IgA and IgG.
The results of the study showed Giardia infection up to 95%.
This analysis was also set up to evaluate the effectiveness of the treatment. If the number of parasites decreases, then the method of recovery is chosen correctly.
scrape
A smear is taken to diagnose enterobiasis, which is the presence of cream worms in the body.
Erosion is done in the following way:
- Use a special spatula or regular cotton.
- Using masking tape.
This test is considered more effective than a regular stool test. It can be done independently or in a clinic. You need to take a cotton ball or tape and make a swipe on the anus.
Do not wash before the procedure. If scraping is done at home, a spatula or adhesive tape (attached to the glass) is placed in an airtight container and taken to the laboratory. For more accurate results, the analysis was given several times.
When and where should I be tested for worms?
Analysis for parasites must be taken with obvious symptoms of helminthic invasion: With asthenia, digestive problems, sudden weight loss and dermatological diseases. In addition, a diagnosis for the presence of helminths is necessary in situations where a person has been treated for a chronic disease for a long time, and recovery has not occurred. Often, the pathology is provoked not by physiological problems, but by the presence of parasites in the body.
Testing is mandatory for the following symptoms:
- Itching in the anus.
- Dysbacteriosis.
- Lots of saliva.
- Pale skin.
- Urinary incontinence.
- Constipation turns into diarrhea.
- Pain in the abdomen of various localizations.
- In women, the menstrual cycle is disrupted.
Analysis given:
- at the district clinic.
- In a medical research laboratory.
- In a private clinic.
The main thing is that the medical institution has the necessary equipment and qualified staff.
What tests are done to detect parasites?
Basically, one analysis is enough to detect worms in the body.
Recommended:
- Lulus cal.
- Do the scraping.
Validation of this analysis was carried out rapidly. In most cases, they are enough to identify parasites. Sometimes, blood tests are prescribed, but the procedure is more complicated, painful and expensive.
Interpretation of the results was carried out by the attending physician. Based on the indicators, the specialist makes a final diagnosis and selects a therapeutic program.
Prepare for testing to detect worms
It should be noted that no special training is required. But there are some guidelines and limitations.
They are as follows:
- Before passing the analysis, it is necessary to eat mainly snacks or reject them altogether.
- You must stop taking the medication 3 days before the test. Some components of the drug may distort the results of studies.
Be sure to inform your doctor about any pre -existing illness. This also applies to pressure surges, the possibility of fainting and poor blood clotting.
Everyone who cares about his or her health must be checked for the presence of worms. Helminthiasis is considered a dangerous disease. Worms absorb substances needed by the human body and release toxins. Therefore, it is desirable to identify parasites in a timely manner so that they do not have time to cause serious harm to health.
