In the human body, many types of helminths can parasitize, so there are various tests to detect them. Each diagnostic event has its own percentage of reliability and is distinguished by several implementation features.
In the human body, many types of helminths can parasitize, so there are various tests to detect them. Each diagnostic event has its own percentage of reliability and is distinguished by several implementation features.
Fortunately, unique techniques have been developed to detect parasite infection at an early stage and to begin treatment in time.
What tests will you need to pass to detect worms?
To determine the presence of parasites, an analysis is not always enough, as at different stages of development, the worms manifest in their own way.
The main types of analysis are distinguished:
- Preventive. Allow timely detection of helminthiasis. This can be done, even in the absence of typical symptoms. It is recommended to conduct the study every year.
- Barrier. Reduce the risk of spreading parasites in the population. It is considered mandatory when you get a medical book.
- By order of the doctor. Tests are given if there are characteristic signs of helminthic invasion: nausea, itching in the anus, abdominal pain and fatigue.
To accurately determine the presence of worms, you will need to pass several tests. In addition, some of them pass several times.
Fecal analysis for parasites
Fecal analysis is the simplest analysis done in any district clinic. The results show the presence of worm eggs in the feces. It is in it that helminth eggs are contained.
Mature individuals can lay thousands of eggs a day. Some of them spread through the blood throughout the body. But, fortunately, most come naturally.
For the analysis to be reliable, it is necessary:
- You have to switch up to 3 times. This is because the risk of swallowing eggs by a healthy person is high, although this does not mean that he will be infected immediately.
- The horse is given at a time interval of 7 days.
- Feces are taken from different places.
It is not necessary to collect the material in the morning, this can be done in the evening, but can be stored no more than a day and in a cool place.
If a large number of eggs are detected during the study, no further analysis is required.
Complete blood count to detect worms
Such a study is known to all since childhood. Basically, blood is taken from a finger, but sometimes from a vein. Research will quickly determine the cause of each disease.
Usually, a person does not suspect that he has worms. Therefore, it is important for the doctor to learn about the symptoms that are characteristic of the infection.
This analysis is able to:
- Determine the cause of the symptoms.
- Detect the presence of parasites in the blood.
- Confirm the presence of other pathologies.
There is a misconception that helminths live only in the gastrointestinal tract. In fact, many species, having penetrated the stomach, then penetrate the bloodstream and spread throughout the body. This is not without serious consequences. The parasites leave a mark, which doctors detect in the blood.
Hemosti
Finding information about this study is not easy and the term itself is not familiar to many people. In fact, for the patient, this is a blood donation procedure for a general analysis. Differences in the laboratory studies themselves.
The task of the most hemot:
- Determining the immunity of any product from the body.
- What is the reaction to them.
Basically, this study is prescribed by a doctor. Hemotest is able to detect parasites that could not be detected otherwise. This study is considered the most reliable.
Various manipulations are performed on the blood taken from the patient. Influenced by biological and chemical substances, observing the reaction. It is different, and some indicate the presence of helminths.
Such a test is quite complicated and is not performed in every clinic. The result is known after 2-5 days. In 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, intercellular parasites and viruses. Blood and other body fluids are taken for analysis. If the presence of worms is suspected, then feces are used for research.
The discovery of even some fragments of parasite DNA in biomaterial indicates helminthic invasion. PCR analysis is quite simple, the result is known after a few hours. This is facilitated by the use of special equipment. With this test, you can not do much extra research, but quickly get the desired result.
Unfortunately, not every clinic has such equipment and the cost of this analysis is quite high.
ELISA blood test for worms
The most popular and reliable analysis today, experts call immunoassay enzyme for parasites.
The main purpose of this high-precision laboratory method is to detect antibodies to a certain type of parasite in the blood. Immunoglobulins (also called antibodies) are a natural reaction of the immune system and aim to neutralize the negative agent.
An enzyme-linked immunosorbent assay (ELISA) shows a change in antibodies in the blood. The study is great for identifying parasites.
It is divided into 2 stages:
- immune system reaction. Can bind molecules, microorganisms and cellular elements to be detected.
- enzymatic reaction. You can visually evaluate the results of the reaction.
Serological blood test
With the help of this laboratory method, infectious diseases are discovered, as well as the stages of their development.
This test allows:
- Determine the patient's immune status. When infected with parasites, the immune system is significantly weakened.
- Detects the presence in the blood of bacteria that caused a decrease in 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 the analysis of enzyme immunity. The analysis determines the density of antibodies to worms of a certain species.
When infected, IgM antibodies appear in the blood, and after 2 weeks - IgA and IgG.
Study results show Giardia infection up to 95%.
This analysis is also prescribed to evaluate the effectiveness of treatment. If the number of parasites is reduced, then the recovery method is chosen correctly.
scratching
A stain is taken to diagnose enterobiasis, i. e. the presence of worms in the body.
Excavation is carried out in the following ways:
- Using a special spatula or a regular cotton swab.
- Using adhesive tape.
This test is considered more effective than a regular stool test. It can be done independently or in the clinic. You need to take a cotton swab or tape and make a stain on the anus.
Do not wash before the procedure. If the scratch is done at home, a spatula or adhesive tape (glued to the glass) is placed in an airtight container and sent to the laboratory. For a more accurate result, the analysis is given several times.
When and where should I get tested for worms?
Tests for parasites should be taken with obvious symptoms of helminthic invasion: with asthenia, digestive problems, sudden weight loss and dermatological diseases. In addition, diagnosis for the presence of helminths is necessary in situations where a person has been treated for a chronic illness for a long time and cure does not occur. Often, the pathology is not provoked by physiological problems, but by the presence of parasites in the body.
Tests are mandatory for the following symptoms:
- Itching in the anus.
- Dysbacteriosis.
- Abundant saliva.
- Pale skin.
- Urinary incontinence.
- Constipation turns into diarrhea.
- Abdominal pain of different localization.
- In women, the menstrual cycle is interrupted.
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 personnel.
What tests are done to detect parasites?
Basically, one analysis is enough to detect worms in the body.
Recommended:
- Kaloni cal.
- Make an itch.
Verification of these analyzes is performed quickly. In most cases, they are enough to identify the parasites. Sometimes, a blood test is prescribed, but this procedure is more complicated, painful, and expensive.
Interpretation of results is performed by the attending physician. Based on the indicators, the specialist makes the final diagnosis and chooses a therapeutic program.
Preparing for worm detection tests
It should be noted that no special training is required. But there are some guidelines and limitations.
They are as follows:
- Before passing the test, it is necessary to eat mostly light foods or to reject it altogether.
- You should stop taking the medicine 3 days before the test. Some drug components may distort the study result.
Be sure to inform your doctor about existing illnesses. This also applies to increases in blood pressure, possible weakening and poor blood clotting.
Every person who takes care of his health should be checked for the presence of worms. Helminthiasis is considered a dangerous disease. Worms absorb substances necessary for the human body and release toxins. Therefore, it is desirable that parasites be identified in a timely manner so that they do not have time to cause serious harm to health.
