Today, most parasitic infections help determine a well-established worm test. Diagnosis is carried out in specialized laboratories using the latest equipment and reagents.
In addition, there are a number of specific requirements for each parasite to perform each analysis. Below we will explain what tests to take for worms and how to do it correctly, as well as how to write them correctly.
Types of worm detection tests
There are several types of analysis where the results can show only one or another parasitic invasion. However, we must not forget that only the attending physician can decipher the results and make a diagnosis.
One of the most reliable and informative (with 93% accuracy) diagnostic methods for helminths is a blood test for parasites. In medical circles, such a study is called ELISA (enzyme-linked immunosorbent assay for the presence of parasites in the human body). The study allows the detection of antibodies in the blood serum that are associated with antigens. That is, in relation to parasitic infections / individuals.
The advantage of such a blood test for parasites is the ability to detect helminthic infestation at an early stage when the helminth is not yet able to reproduce and has not laid an egg that can be detected by a coprogram (a special analysis of feces for ovarian leaves).
For parasites, it is important to understand that this blood test can detect the following parasitic infections:
- Trichinosis and others.
Blood for parasites is taken from a vein on an empty stomach in the morning. In this case, it is worth taking preparatory measures before conducting research.
Follow these rules for blood tests, especially for parasites:
- Do not eat greasy, fried, complex dishes for three days before diagnosis. Food should be simple and easily digested;
- Alcohol and any medication should be stopped three days before work;
- The day before donating blood for worms, you should limit yourself from excessive physical and psycho-emotional stress;
- It is worth quitting smoking at least 3-4 hours before.
Important:Taking a blood test for parasites in accordance with all the above rules will allow you to get the most accurate result and rule out a false positive result. If the reader is interested in how long the analysis of parasites takes, then the time to obtain such a result will vary from 3 to 9 days.
In addition to being able to donate blood for worms to get accurate information, you can donate feces to a coprogram for the same purpose. This type of diagnosis allows the detection of helminth eggs in the feces during active reproduction. Therefore, if you do not know how to test for worms, but want to do it yourself and immediately, you can go to any commercial laboratory that has fecal samples for research. By the way, the family doctor will first apply for such an examination if you suspect helminths.
It is important to understand that if a blood test for worms reveals the maximum number of parasites in the body, the list of worms in the stool study will look slightly different.
In particular, fecal samples can be identified for worms, eggs, and individuals of the following worms:
- Liver and cat pains;
- created a ribbon;
- Established a ribbon of pork and beef;
- Wide ribbon;
- Schistosoma and others.
It is important to know that such a study is not always informed, because the parasite may be in the maturation stage during the delivery of feces and is not yet ready to lay eggs. Therefore, it is recommended to take the stool test three times with an interval of 2-3 weeks to get a reliable result.
For those interested in how feces can be tested for parasites, it is important to know that feces should be collected in a sterile plastic container after morning bowel movements. No need to wash yourself before going to the toilet. At the same time, it is advisable to do your work not in the toilet, but in a bowl devoid of disinfectant or detergent particles.
It is important to ensure that urinary and genital secretions do not enter the biomaterial. Collect samples from different parts of the stool (front, back, and side). Fecal matter collected in a 2/3 container should not be stored and should be sent for analysis immediately. Because parasite eggs can live in the environment for up to 10 hours. Retention of the sample reduces the likelihood of obtaining a reliable result.
Important:The doctor should also mention that the stool will be properly forgiven when sending an application.
If the reader is interested in how many days this type of test will be performed, the diagnostic time is shorter than a blood test for parasites. In most cases, the result is ready by the evening and sent to the patient's e-mail (if the diagnosis is made in a commercial laboratory). The maximum time for a coprogram result is 1-2 days, including weekends.
Important:For the youngest patients, enterobiasis analysis is often performed in the form of a spoon. To do this, a piece of adhesive tape is applied to the skin folds of the baby's anus and squeezed well. The sample is glued to a special laboratory glass and sent for examination. In this way pinworm eggs can be detected.
When is a worm test required?
Testing for worms is recommended primarily for people who are most at risk for infection.
Medical experience shows that helminthic invasion is more common in the following human categories:
- Workers in frequent contact with animals: farmers and veterinarians;
- hunters and fishermen, as well as those who like to travel to the wild often for recreation;
- people living in rural areas where various infectious diseases often occur;
- health workers who are often forced to communicate with infected patients;
- Those who work in kindergartens, schools and other public places. We must not forget the cooks and people who work in the catering sector, who are often forced to deal with raw meat, fish, vegetables and greens, because often the products must be tasted before they are completely cooked;
- People who do not follow personal hygiene cannot eat their hands before eating, and perhaps the products themselves before eating;
- An ordinary city dweller who may have cockroaches or flies or other insects in his house, because ants are carriers of such various helminths.
All of these people should have a blood test for worms or a skin itch, and feces are possible. The attending physician is responsible for choosing the right type of test depending on the symptoms of the infection.
Symptoms may be different, let's look at the basics:
- A sharp decrease in weight, a person has a good appetite and eats more than usual. But over time, the appetite disappears, as the general condition worsens;
- itching and irritation in the anus, burning in the anus is possible;
- pallor of the skin due to lack of nutrients, vitamins are no longer absorbed and all useful vitamins and minerals are depleted by worms;
- Chronic fatigue and tiredness appear due to decreased immunity and vitality;
- The presence of problems in the gastrointestinal tract, from nausea and vomiting to pain and stool problems, indicates the need for examination for worms in adults in the first place;
- Headache and dizziness associated with the release of toxins by worms.
If you or a loved one has a health problem and has at least 2-3 symptoms on the list, the risk of worms is high.
Statistics show that most people on the planet are infected with helminths, but do not know about them as they continue their treatment due to the results of parasitic helminths. Therefore, ask the clinic what tests are being done for worms and get an examination to get rid of the root cause. It is recommended that you pay attention to the preparation process before asking yourself what tests you will take for worms for an adult or a child.
Preparing for a test for worms
Blood or stool tests must meet certain requirements, for which certain preparation rules must be followed:
- One week before the tests, you should not use anthelmintic drugs, both in dosage form and in various folk remedies, as this can lead to a negative test result, even in the presence of helminthiasis;
- One week or 4-5 days before the planned visit to the clinic, you should refrain from sorbents and laxatives, otherwise the tests may be negative;
- About 3-5 days before visiting a medical institution, you should eat a diet, do not drink fizzy drinks, eat sweet, sour, spicy and smoked foods, as well as avoid fatty foods.
With these simple but effective preparations, a blood or feces worm test will be the most accurate, meaning you can start treatment quickly.
Analysis for ascariasis
Ascariasis is widespread in children and adults: it affects up to 20% of the world's population. Ascaris worms, like pinworms, belong to the group of nematodes, but they look even more terrible: the body length can reach 30-40 centimeters. Fresh vegetables and fruits are generally the source of the disease: roundworm eggs in the soil can live for several years, sitting on a flat table in the garden.
Symptoms of ascariasis are weakness, fatigue, itching in the anal area. Roundworms can spread to all parts of the body, damaging the liver, respiratory tract and gallbladder - in this case, secondary symptoms caused by organ diseases are added to the initial symptoms.
The development of ascariasis can even lead to the death of the patient.
A blood test for antibodies is the most effective way to detect ascariasis in the body.
No special preparation is required, but it is recommended not to eat for four hours before the analysis.
Opisthorchiasis is caused by flatworms - cat's wings. There is an obvious local spread of the disease. You can get opisthorchiasis by eating infected fish, which is a mediator of the parasite. Worms develop in the bile and pancreatic ducts, causing infections, allergic reactions, liver disease, kidney pain and fever.Lack of timely treatment can lead to damage to the central nervous system, chronic gastritis, gastric ulcers and duodenal ulcers.
A blood test for specific IgG antibodies is the most effective way to detect cat flu. A reliable result can be obtained when working between the sixth and eighth week after infection. During the transition to the chronic phase, the indicators may return to normal, in which case it will not be possible to determine opisthorchiasis by this method.
Analysis for Trichinosis
Trichinosis, Trichinella - is caused by helminths that enter the human body through contaminated meat and lard. Food in large stores should be inspected for the presence of parasites, so private farmers, hunters, and people who buy meat in uninspected areas are victims of Trichinella. The eggs of this parasite cannot be destroyed by ordinary heat treatment, and salting and smoking do not help. A small piece is enough for infection.
Symptoms of the disease in the first two to three weeks are allergic reactions, nausea, diarrhea, vomiting. Then there is an organ disease in which worms develop: parasites can pick up any part of the body and destroy it for many years. As a result, trichinosis can lead to the death of the patient or irreversible damage to the body.
If you suspect the presence of Trichinella, the patient is referred for a blood test for specific antibodies. It is recommended to have a second examination a few weeks later with a negative result and persistent symptoms: the disease cannot be detected in the early stages, and a high accuracy is obtained with a blood test in the second to fourth weeks after infection.
