How to check for the presence of worms in a person: checking for their presence in adults

The most accurate way to detect the presence of parasites in the human body is to help with laboratory tests. Blood and stool samples are most often needed to check for worms.

Each of the modern methods has its drawbacks and advantages. For this reason, doctors recommend a comprehensive examination of the body to determine if a person has worms.

Analysis of the feces of the parasites shows the presence of larvae and eggs of helminth samples. However, the results of tests do not always allow an accurate diagnosis to be made.

This fact can be explained by the fact that worms have several specific phases in their development, they can occur and parasitize in different parts of the digestive system. For the most accurate results, feces should be donated at least 3 times a week.

If blood samples are indicated, they will reveal antibodies that appear as a result of the human body's response to toxins secreted by the worms. Given that about 150 species of parasites in humans are known today, no research method can be 100% accurate.

Are there worms or no?

pain in the abdomen with parasites

Everyone knows that the main indicators that suspect the presence of parasites are:

  1. excessive thinness in the background of increased appetite;
  2. pain in the abdominal cavity after a meal;
  3. morning sickness.

Such symptoms allow you to simply suspect worms at home, however, an accurate diagnosis can be made after the body has been diagnosed and tested for parasites. These signs may indicate gastrointestinal pathologies, metabolic disorders, and other diseases.

If you have worms, the symptoms are: bloating, intermittent discomfort in the abdomen, stool problems (diarrhea, constipation), stomach upset after eating, these may be worms in the abdomen.

Many, after discovering signs of a parasitic infection, immediately start taking all kinds of medication and switch to a frugal diet. In the vast majority of cases, such measures are useless, sometimes even harmful. Before starting treatment, the presence of worms should be checked, especially if symptoms have joined:

  • discomfort around the anus;
  • decreased immunity, frequent colds;
  • skin rash (urticaria), inflammation (boils);
  • persistent cough does not go away after treatment.

Parasites can adversely affect the functioning of the central nervous system. This is evidenced by signs of excessive nervousness, irritability, fatigue.

When to give blood

blood sampling for parasite analysis

Blood tests are performed for the presence of worms if a person is worried about headaches, skin problems, itching around the anus, insomnia, indigestion (diarrhea, stool mucus contamination, constipation). In case of parasite invasion, the patient notices the excessive fragility of the nails, the hair loss.

If a child is ill, their symptoms may be different. In addition to these signs, strong mucus secretion, increased appetite, and a lack of concentration are observed.

Therefore, a blood test for the presence of worm antigens is an important diagnostic measure that allows the detection of parasites in the body to detect the disease as early as possible. There is an opinion that it is enough to give only a stool sample to make a diagnosis, but this is not the case. Blood tests are rarely done because patients do not want to waste time and money.

Not everyone knows that eggs are found in feces only if they are worms

  1. filled the intestines;
  2. is actively developing;
  3. they reproduce.

Blood tests on worms in adults show infection at a very early stage. To perform such an analysis, blood must be taken from the cubital vein, which allows for accurate and rapid identification of parasites and selects ways to get rid of them.

Blood sampling is also required if worm infection is suspected if intestinal worms are found in domestic animals for epidemiological diagnostic measures in a particular region. Increased blood leukocyte levels are needed to check if a person has worms, which does not indicate other pathological conditions.

Routine testing is sometimes performed on people whose professional activities are closely related to an increased risk of parasitic infection, usually in this group:

  • workers in meat packing plants;
  • farmers;
  • veterinarians.

To determine the presence of antibodies against parasites, fibroids, an inflammatory process in the adrenal glands, bladder, kidneys, are needed in women. Men are presented with a blood test for prostatitis, adenoma and impotence.

There is a proven sign that worms may be in the body, indigestion. In this case, blood tests are performed on both men and women.

Stool analysis

tests to detect parasites

To achieve an accurate result, the patient must follow clear rules. So 1 week before the analysis, antiparasitic, anti-diarrheal and antibacterial drugs, castor oil and mineral oil should be stopped.

If colon examination is not planned (barium enema), blood donation is allowed no later than 2 weeks after stool analysis. You should be aware that it is forbidden to store the container containing the substance at a positive temperature. Optimally - 4-8 degrees does not exceed 8 hours.

Feces are tested for the simplest types of parasites as follows:

  1. take 2 teaspoons of stool;
  2. transfer to a clean, dry container;
  3. cover with a lid.

Ideally, material should be taken from different parts of the feces. For an accurate answer, the stool is collected no later than half an hour after defecation, and the vessel is transported to the laboratory immediately.

It is important to note that a single test for human-borne worms is not always sufficient, especially for worms and roundworms. Accordingly, the analysis is repeated at least 3 times with a frequency of 1-2 days.

How to pass the scraper

Before scraping to check for the presence of worms, you should be familiar with the basic rules of the procedure. First, it is forbidden to wash the area around the anus, as this will destroy traces of parasites. For the most accurate results, it is equally important not to empty the bowels before scraping.

Scraping of worms is handed over in a laboratory or office, but worms can also be detected at home. It is recommended to wear medical gloves before sampling.

If there is a suspicion of enterobiasis, it is better to use a special test tube with a long rod inside. The end of this rod should be wrapped in cotton wool and then carefully soaked:

  • glycerol;
  • distilled water;
  • saline solution.
scraping for parasite analysis

The procedure is quite simple and does not require much effort. The container is opened, a cotton ball is taken, the bottom is squeezed, and the rod is guided around the anus.

The rod containing the resulting biological material is returned to the container so that it does not touch the wall, and the container is sealed.

The result of the test will be reliable if a sample of the biological material is delivered to the laboratory as soon as possible.

The presence of parasites can be determined in other ways, for example by means of a glass plate with a special adhesive tape.

Physicians insist that analytical technology be performed accurately. So you need to pull the sticker off the glass plate first, attach it to the skin around your anus for a few seconds, spreading your buttocks in front of it. Then:

  1. the tape is again fixed to the glass plate;
  2. the substance is referred to a medical institution where the test is performed.

There is another equally important rule: when collecting biological material, it is forbidden to touch the tape and the glass with foreign objects. In addition, you should not store the analysis in the refrigerator, as this will greatly affect the test result and reliability.

In our time, it has become possible to check for the presence of a parasitic infection by taking a saliva sample. The test is simple, the patient does not require any prior preparation. A disposable container of special reagents is taken to identify the 11 most common types of worms.

The method has advantages and obvious disadvantages, such as detecting the presence of worms in all tissues of the body, and the downside of the procedure is the rather high cost of the test.
