The most accurate way to indicate the presence of parasites in the human body is to help with laboratory tests. Usually, to test for worms, you need to take blood and stool samples.
Each modern method has its advantages and disadvantages. For this reason, doctors recommend a thorough examination of the body to find out if a person is infected with worms.
Analysis of stool for parasites will reveal the presence of larvae and eggs of helminths. However, the results of the tests do not always allow you to make an accurate diagnosis.
This fact is explained by the fact that worms have many specific stages of development, which can occur and parasitize in many different parts of the digestive tract. For the most accurate results, you need to donate at least 3 times a week.
If a study of a blood sample is indicated, they will reveal antibodies that appear as a result of the human body's response to toxins secreted by the worms. The fact is that today there are about 150 species of parasites living in the human body known, no research method can be 100% accurate.
Are there worms or not?
Everyone knows that the main indicators on the basis of suspicion of the presence of parasites:
- excessive thinness of a person against the background of increased appetite;
- pain in the abdominal cavity after eating;
- intermittent morning sickness.
Such symptoms will allow you to suspect worms at home, however, an accurate diagnosis can be made after, through the diagnostics of the body, passing tests for parasites. These signs can indicate pathologies from the organs of the gastrointestinal tract, metabolic disorders and other pathologies.
If you are infected with worms, the symptoms will be as follows: bloating, periodic discomfort in the abdominal cavity, stool disorders (diarrhea, constipation), after eating may see a heavy abdomen, this could be wormsin the belly.
Many people, after detecting signs of being invaded by parasites, immediately begin to take all kinds of drugs, switch to a diet. In most cases, such measures will be futile, sometimes even harmful. Before starting treatment, it is necessary to test for worms, especially if symptoms are present:
- discomfort around the anus;
- reduced immunity, frequent colds;
- skin rash (urticaria), inflammation (boils);
- persistent cough, it doesn't go away even after treatment.
Parasites can adversely affect the functioning of the central nervous system. This is evidenced by signs: excessive stress, irritability, fatigue.
When to donate blood?
A blood test for worms will be done if a person is concerned about headaches, skin problems, itching around the anus, insomnia, digestive disorders (diarrhea, mucus impurities in the stool, constipation)). With an invasion of parasites, the patient will note excessive fragility of the nails, hair loss.
If a child is sick, his symptoms may appear differently. In addition to these signs, you may experience increased salivation, increased appetite, and lack of concentration.
Therefore, blood test for filariasis antigen is an important diagnostic measure to help you detect parasites in the body, identify the disease as soon as possible. It has been suggested that a stool sample is sufficient for diagnosis, but that is not the case. Blood tests are rarely done because patients don't want to waste their time and money.
Not everyone knows that eggs in feces can only be found if worms
- filling the intestines;
- actively develop;
Blood tests for worms in adults will show the infection at a very early stage. To conduct such an analysis, blood should be taken from the cubital vein, which will allow you to accurately and quickly determine the type of parasites, and choose how to get rid of them.
It is also necessary to take a blood sample if helminthic infection is suspected, if detected in livestock, to take measures to diagnose the epidemiology in a specific area. To check if a person is infected with worms, an increased white blood cell count is required, which does not indicate other medical conditions.
Occasionally, a routine examination is performed on people whose occupational activities are closely associated with an increased risk of infection with parasites, as a rule, this group includes:
- workers of meat packing plants;
To determine the presence of antibodies to the parasite is necessary for fibroids, an inflammatory process in the adrenal glands, bladder, kidneys in women. Men have blood tests to look for prostatitis, adenomas, and impotence.
One proven sign that worms can survive in the body is indigestion. In this case, blood tests are done for both men and women.
To get an accurate result, the patient must follow clear rules. Therefore, 1 week before the analysis, it is necessary to stop taking antiparasitic, antidiarrheal and antibacterial drugs, castor and mineral oils.
When there is no scheduled colonoscopy (barium enema procedure), blood donation is allowed no later than 2 weeks after stool analysis. It should be noted that the container should not be left with the material at positive temperatures. Optimal - it is 4-8 degrees no longer than 8 hours.
Stool testing for the most common types of parasites is done this way:
- drink 2 teaspoons of feces;
- transfer to a clean, dry container;
- cover with lid.
Ideally, you need to get the material from different parts of the stool. For a definitive answer, stool is collected no later than half an hour after defecation, and the flask is immediately shipped to the laboratory.
It is important to draw the patient's attention that a single study to detect worms in humans is not always sufficient, especially for pinworm and roundworm eggs. Accordingly, the analysis was repeated at least 3 times with a frequency of 1-2 days.
How to get over a shave
Before checking for the presence of worms by scraping, you need to familiarize yourself with the basic rules for this procedure. First of all, do not wash the area around the anus, as this will destroy any traces of the parasite. For the most accurate results, it is equally important not to clean the intestines before curettage.
Dewormers are delivered in the laboratory or in the clinic, but can also detect worms at home. Medical gloves should be worn before sampling.
If there is a hypothesis about the development of filariasis, it is better to use a special test tube with a long rod inside. The end of this stick will need to be wrapped with cotton wool, then gently blotted with water:
- distilled water;
- physiological saline.
The procedure is quite simple and does not take much effort. The container is opened, take a cotton swab, push the buttocks out, then insert the stick through the anus.
The rod with the resulting biological material is placed back into the container, trying not to touch its walls, and the barrel is closed.
The results of the study will be reliable if the sample of biological material is delivered to the laboratory as soon as possible.
You can determine the presence of parasites in other ways, for example, using a slide with special adhesive tape.
Doctors insist that analytical technology needs to be done precisely. So, you need to first peel the patch off the slide, stick it on the skin around the anus for a few seconds, spreading the buttock area first. Afterward:
- tape is attached to the slide;
- materials are transferred to a medical facility where the study will be performed.
There is another equally important rule: when collecting biological materials, do not allow foreign objects to touch the ice, glass. In addition, you cannot store the analysis in the refrigerator, as this will greatly affect the results and reliability of the study.
In our time, it is possible to check for the presence of a parasitic infection by taking a saliva sample. The examination is very simple, the patient does not require any preliminary preparation. They took a disposable container, a special reagent that identifies the 11 most common types of helminths.
This method has obvious pluses and minuses, for example, the ability to detect the presence of worms in all tissues of the body is beneficial for the test, and the negative side of the procedure is the cost of the research. quite tall.
