Information that 80-90% of people are infected with worms, many people come with the idea that you need to take anthelmot medication for prevention purposes.
The human body parasitization of various types of worms, special tests have been developed for their identification.Each diagnostic procedure has a certain percentage of reliability and is different in behavior features.
Blood test for parasites
Vital parasitic activity in the body causes unclear etiology malaise.This can be a skin rash, flatulence, heartburn, nausea, weakness, anemia, joint pain.To clarify the diagnosis, special tests for parasites must be carried out.
How to check parasites in the human body
Parasitic classification in their appearance:
For representatives from several professions (for catering company personnel, children's institutions), worm egg analysis is needed in the design of sanitation books.Children pass the same analysis after entering the Kanak -Kankanak Park and nurseries or in the sports section.
- A classic study of worms living in the digestive tract is the analysis of the stool and mucosal friction of the rectum.
- But there are several options for blood tests that are more effective for parasites, as intended and according to this method.
The reason for sending analysis for parasites
When infected with individual parasites, a person may not feel any symptoms.But over time, the number of worms increases, and infection begins to materialize.It is important to take a parasitic test if there are symptoms like that:
- Abdominal pain from different localization, which can occur spontaneously or in palpation;
- Itching in the anus that appears at night;
- joint pain and muscles;
- reduce appetite and nausea;
- increased appetite with abundant saliva;
- Intestinal dysbiosis;
- Constipation or diarrhea;
- stool color changes;
- Increased fatigue;
- Dizzy;
- pale skin;
- insomnia or sleep disorder;
- irritability;
- skin infection;
- Urine incontinence;
- In women, vaginal discharge from the vagina, violations of the menstrual cycle.
The nature of symptoms depends on the type of parasite.Itching and burning in anal regions causes pinworms.Askarides provoked severe allergic reactions, as well as cramping abdominal pain.Lambia, Echinococci and Bicondumur affect the liver.They are often a cause of bile duct obstruction and cholestasis (bile stagnation), inflammation of the gallbladder.Light stool with fat drops is one of the main signs of liver pathology and pancreas.Symptoms of parasitic effects on the liver and gallbladder are pain in the right hypochondrium.
If some of the registered symptoms appear, it is necessary to go to the hospital to identify parasites in the body on time.It is important to take a routine prevention test for parasites for children, people who live or work with animals.If raw meat, jerked, slightly salty, pork fat or fish regularly consumed for food, the risk of infection is very high.In this case, it also needs to be checked regularly to identify parasites.
What test for parasites exists
There are various reasons that cause the need to take analysis for worms.
In this parameter, 3 types of tests are distinguished:
- Prevention - It is necessary to detect timely helminthiasis even without any characteristic symptoms.They are carried out on a person's personal initiative or in a medical examination.It is recommended to take such analysis every year, especially for children.
- Barrier - prescribed to minimize the risk of the spread of helminthiasis between the population.This is a mandatory analysis that is passed by children before entering the Kanak -kanak or school park, food industry workers, service areas, medical staff to get medical books.Barrier analysis is provided once a year.
- As determined by the doctor, the type of analysis for this worm is prescribed by a doctor in front of symptoms of helminthiasis characteristics: nausea, stomach disorders, itching in the anus, weight loss, abdominal pain, increased fatigue, dizziness.With a single negative results, the analysis must be taken again to ensure its reliability.
Depending on the situation and symptoms, one or more types of tests are determined.Let's consider in detail each feature.
With a sharp weight loss, you should think about the need to do an analysis for parasites
Calais analysis for worm eggs
Analysis of stool for parasites, in other ways, is called the Coprogram-A method that provides stool mass studies under a microscope to identify parasitic eggs, larvae or fragments of sexual cooked worms.This analysis makes it possible to identify many worm varieties, but is very effective for parasitic worms in the intestine.Suitable for the diagnosis of enterobiosis, ascariasis, ankylostomosis, trichocephalosis and other types of infections.
To do an analysis, you need to take a special sterile jar.This is issued in the clinic, laboratory or purchased at a pharmacy.
Then everything is simple:
- It is important to fill 1/3 with feces with feces.This must be done before 11.00 hours.Make sure that third -party feces, for example, blood, other secretion drops do not fall into the jar, because this will negatively display the reliability of the results.
- CLOSE The capacity filled must be tightly closed.It was signed, and then packaged in disposable packages.
- The best is if the material can be transferred for analysis 30-45 minutes after the collection.Allowed to store it in the refrigerator, but no more than 8 hours.After this period, the material becomes unsuitable for analysis.
You can find out the results the day after the analysis.But in some laboratories it was carried out for up to 6 days.
The effectiveness of this method is 30-35%, because the pump is not laying eggs every night.
Erode (stain)
Eroding is the most common analysis for enterobiosis, which allows you to identify the presence of parasitic pinas worms in the intestine and place large amounts of eggs in the area around the anus, as well as in the perineum area every night.
Because children often suffer from enterobiosis, a child who visits the Kanak -Kankakan Park, a school, needs to do a regular scratch twice a year.Adults also need to do an analysis when the first parasitic signs appear: itching in the anus, bad sleep, worsening appetite, weight loss, irritability.
Analysis Procedure:
- Friction is taken by a special spatula, which is available in a pharmacy, or with ordinary cotton, which was previously moistened in saline or warm water.They remove stains from the area around the anus, as well as the perineum.Another way is to install a sticky band (ribbon) to the area around the anus.Gently removed, must be glued to the surface of clean and dry glass.
- The procedure must be carried out in the morning, immediately after waking up.Before that, you can't go to the toilet and wash.You can take apusan at the clinic or at home.
- Sticks or spatulas, on the surface that have biomass for research, are packaged in sterile dry jars, packages.Packaging must be sealed.
- It is important to send material to the laboratory for research on the day to take stains, it will soon be better.If necessary, for a maximum of 5 hours, it can be stored in the refrigerator.
You can find out the results the next day.
If the first analysis results are negative, but the typical symptom of enterobiosis is maintained, the procedure must be continued again the next day or every day.The maximum effectiveness guarantees 3-4 negative results from the analysis carried out in a row.
Blood test
Blood tests show parasites, because as a result of their lives, they affect internal organs, mucous membranes, release a large number of poisons.This triggers changes in blood composition.When worms appear, the immune system begins to produce antibodies (immunoglobulin).They can be identified as a result of this study.
The main thing is that the competent decoding of the results is done, which can only be done by experienced specialists.
The blood test for parasites determines all its varieties - ascaride, lamblia, flat worms, two water, trichinella, trematodes.Most of them parasites in internal organs: in the liver, lungs, channels, and not in the intestine, therefore, using other tests, will not function to identify this type of parasite.
Analysis Delivery Procedure:
- To do an analysis, venous blood is needed.Enough to take 3-5 ml of material from the elbow vein.The procedure is carried out on an empty stomach, preferred in the morning.
- Specialists study the blood selected in the laboratory for specific antibodies, which allows you to determine the helminthiasis stage.
- Describe the results of the analysis.
Before donating the blood, the patient must pass through the preparation stage.It starts a week before the diagnosis and involves a complete rejection to use antibiotics and other drugs, a composition that can negatively affect the accuracy of the results.The day before the analysis, it is better not to include fatty products, candy, carbonated drinks and always alcohol from the diet.
Determination of worm invasion is also carried out using a general blood test.This is quite informative, allowing you to identify various types of worms, but most effectively in relation to pin worms, and ascaris.
When describing general analysis, the following indicators are taken into account:
- Hemoglobin - with worm damage, reduced;
- Leukocytes - When infected with worms, their concentration increases.
For analysis, blood is taken from the vein.Before the procedure, it is important not to eat 8, but better than 12 hours.Allowed to drink only water.5-7 days before manipulation, it is necessary to stop drinking antibiotics.
Elisa, Analysis for Antibodies and Immunoglobulina
This analysis is based on the body's immune response, the level of protection reaction to parasitic invasion.
- By using ELISA results, you can determine the presence of worms in the body and its type.The accuracy of this study is far higher than feces analysis.
- This method is based on the calculation of antibodies in the body to one or another type of parasite, determining their relationship with foreign antigens (immune responses) and body enzyme reactions.
- Anti-otigen antibodies show infection.
- Blood tests by Elisa have accuracy, according to different experts, from 60% to 90% even at a low level of invasion.
- The advantage of this method, in addition to a high level of accuracy, is that the analysis of immuno function can be monitored by the dynamics of disease from time to time.
Polymerase chain reaction (PCR analysis)
The PCR method is one of the most modern and accurate for the diagnosis of blood for the presence of parasites in the body.This consists of detecting traces of DNA and RNA, belonging to the form of parasitic life.
- The core of the polymerase reaction is blood treatment in such a way as to copy and spread DNA, the RNA of foreign organisms to concentrations that allow them to determine.
Serological blood test
At the same time, the analysis is used as a source of blood serum information.
- Immunogenic parasitic antibodies are investigated.
- This analysis allows you to identify a large number of parasitic forms, but it does not allow you to determine the invasion stage.
- Like the IFA method, serological analysis is indirectly for diagnosis.
- If the OPD values are high, it is recommended to also pass the stool analysis.
How and where to take a parasitic test
It is important to take a parasitic test when symptoms that are typical of worm invasion appear: digestive problems, asthenia, weight loss, dermatological disease.It is also important to undergo a diagnostic for defects in situations where a person has suffered from chronic diseases for years, but treatment does not provide the expected results.In many cases, it turns out that this disease is provoked not by physiological problems, but by the consequences of worm parasitization.
Before going through the procedure, you need to get directions from gastroenterologists, infectious disease specialists, proktological experts, therapists, surgeons, dermatologists, and pediatricians.With this direction, someone goes to the laboratory.After a biomaterial study, it receives the shape of the yield, which shows whether the worms are detected in the body.
If the analysis results confirm the presence of worms, it is important to immediately consult a doctor who qualifies.This can be a specialist or therapist infectious disease.When Helminthiasis is diagnosed with a child, a pediatrician will help.
To take a test that identifies parasites, it takes at least once a year.To undergo a diagnostic, it is important to choose a good laboratory, whose specialist guarantees maximum accuracy of results.
