A blood test for parasites is a mandatory procedure, that everyone who works in the health, education, animals, or plans to visit educational institutions. In contrast to the studies of the stool, modern blood worms in order to get accurate results, provide an opportunity to assess the infection and to track the effectiveness of treatment. Surveys of this type quickly, doesn't require much time to decipher.
When and to whom you need to give a blood test for helminthiasis?
Sad medical statistics suggests that about one in every 3 persons in the problem of the worms is critical. Household transportation, office and educational institutions, the unwashed fruits, the vegetables, the handshake — all these familiar to every adult and child cases, and the main source of infection. Even if the symptoms are not immediately obvious, that in every case, parasites have an extremely negative impact on the human body: because a bad appetite, contribute to allergies, pain in the damaged organs, a bad digestion, sometimes it can cause death. In view of this, should be given the parasites tests for each person (preferably every year).
Can't be the test, if they seem typical symptoms of helminthiasis:
- the sudden weight loss;
- urticaria;
- frequent nausea;
- aversion to food;
- drastically reduced the hemoglobin;
- irritability or insomnia in children.
In addition, you can also call the group of people who needed every 6-8 months to check the blood. These are in particular the following:
- persons living in areas, where common diseases helminthiasis;
- those who work in educational institutions, as well as dealing with the young children;
- health professionals;
- all catering;
- people working, animals, as well as the family members (veterinarians, workers in meat processing plants, shepherds, breeders, circus workers, animals, garden, etc.).
In addition, the blood worms over all the children of school, preschool age, which will soon be school clubs. To investigate the blood parasites to pregnant women, children before the vaccination. In addition, repeated tests need to pass, after this treatment against parasites.
IFA as one of the most effective method for the diagnosis
The most popular, reliable analysis professionals today called enzyme immunoassay with the blood of the parasites. The main purpose of this highly accurate laboratory method to identify antibodies to a particular type of parasite. The same immunoglobulin (also called antibodies) is a natural reaction of the immune system, and the goal is to neutralize the negative agent.
In order to get an accurate diagnosis and find out what intensity the disease parasites, how long does it take the professionals to manage the 3 different types of immunoglobulins:
- A. class. Detected in the blood in a child or adult is approximately 2-4 weeks after the infection. Almost 80% of the excreted in the mucous membrane, and only 20% remains in the blood. After treatment, immunoglobulin, currently no more than a month. If the second test for parasites again detect them, then the disease passes to a chronic form.
- Class M. in the rapidly responds to the presence of the parasite. In the blood detectable by day 5 after infection. However, they don't stay long — not more than 2 months, and then gradually appear. So, the doctor can conclude that the presence of acute helminthiasis at the moment.
- Class G. appears relatively late— after 1 month after helminthiasisok infection. These, however, displayed a maximum of six months. They are used to understand how long a person suffering from helminthiasis.
Compared to other laboratory methods, ELISA has many advantages, in particular:
- high precision;
- the ability to determine the stage of the disease;
- versatility;
- the possibility that the mass screening of the population;
- fits adult and child.
An enzyme-linked immunosorbent assay suitable to identify the use of this type of helminthiasis as:
- giardiasis;
- another one;
- leishmaniasis;
- ascariasis;
- cysticercosis;
- opisthorchiasis;
- the parasitic infections and the others.
Ákos scan to parasites detection
Ákos — scan - one of the most modern studies, parasites, the children and the adults. Possible to identify the following:
- the specific form of the parasite;
- the structure and the number of white blood cells;
- the number of red blood cells;
- the degree of the viscosity of the blood;
- the immune system;
- the presence of fungi, viruses.
Unlike ELISA, hae-scan provides the fence, just a few drops of blood in the finger. The liquid in the sterile glass, and then carefully examined under a microscope. The number increases to reach 1800-2000 times. You don't need any further treatment (use of enzymes, dyes, sewage, etc.). The modern clinics of the image displayed on the monitor, but because the patient the opportunity to keep the research process, to check the presence of fungi, and helminths. Shock can be a picture of a larvae of parasites. If necessary, run a photo or video of the study.
This is the Accelerated method, because information about the state of the health of the patient to learn 10 to 15 minutes.
It is worth noting that as an independent method of identifying parasites ákos test is not actually used. The fact that the human body is a host to various parasites of various localization. Not in all cases, the migration of the larvae in the blood. Suspect the presence of worms allows you to decreased red blood cell count (like some parasites, blood, nutrients), increased white blood cell count (indicates that the body's fight against the parasite), dense plasma.
The other method, the diagnosis
If method 1 to identify the bot fails, the doctor recommends additional laboratory tests:
- Serological analysis. Also refers to the immunological variants, ELISA. However, unlike the latter, the first objective is to examine, not the blood serum. In order to obtain information, the physician needs to use the reaction between antibody, antigen. Serological analysis did not kill all types of worms, but the fact that the doctor is a suspect. If the human body is a parasite, the specialist will notice a clear reaction.
- PCR-diagnostics. Makes it impossible to ascertain the stage of development of helminthiasisok infection is not recommended the installation of all types of parasites. This will help you can find, it's just that there are in the human body a simple worm. The main task of the technician in this case, the search for DNA, RNA, the parasite. No matter, the parasite is alive or dead. To buy, to research the possibility that any of the materials, especially urine, blood or stool. The greater reliability of such analysis can give you a couple of times.
- Vegetative resonance test. The method is based on the identification of the resonance between the human body and drug. The latter information carriers of the different types of worms. The frequency data of each species of parasites was recorded by scientists in 1989 by art (they call this method) is carried out only under laboratory conditions, and gives the opportunity to identify, what is the situation of the human immune system is a certain period of time. So the VRT doctor can determine if the body is suffering from allergies regardless of toxic, bacteria, parasite effect, or not.
- The complete blood count. Too high or too low hemoglobin, decreased red blood cell count, an increased number of eosinophils, the main characteristics that allow to suspect the presence of the parasite in the human body.
How to prepare the study on how to decipher the results?
Features of delivery of the analysis depends on which method you use, which type of parasites is suspected. In general, the blood in the vein, in certain cases (ákos scan) of a finger. Only 10-15 ml of blood to confirm the diagnosis.
To get the most accurate information, it must be held to certain rules, the delivery of the clinical studies:
- On the eve of the day of the blood draw, the patient should not eat too salty, greasy food (because it can change the level of the white blood cells); the foods that can cause allergies — honey, citrus fruit (increase in eosinophils, which also occurs when helminthiasis); foods rich in essential oils, garlic, onion, ginger (which affects the activity of the parasites).
- It is better to give the substance, on an empty stomach. Free a small amount of clean water.
- It is important to inform your doctor about your medicines, which in the last 2 weeks.
- It is not recommended for a few days before the tests use any physiotherapy treatments (including chest x-ray, ultrasound, x-ray).
- At least one week before blood collection, to give up the alcoholic beverages or medicines that contain high concentrations of ethyl alcohol.
- Smoking should cease at least 2 hours before the test.
If you have a strong helminthiasis suffer pregnant, and the newborn examination is necessary. The blood taken from the umbilical cord or the placenta.
The research is usually 2-3 days. A little more time (up to 5 days) must be filled in, if the package is run immunological tests for various parasites.
Transcript just a specialist. The simplest interpretation remains ákos scanning, and PCR-diagnostics. They don't detect the parasites or the larvae or not.
In a difficult situation, a method that should be called IFA. The doctor is obliged to take account of the immunoglobulins in the 3 groups. So, the acute form of the disease can be said if there will be a combination of: immunoglobulin M positive, The class, or G can be positive or negative. Chronic form of misleading information: immunoglobulin M do not exist, The class G can be positive or negative.
In the event that any of the above mentioned studies have demonstrated positive results, that the delay in the treatment of helminthiasis it's not worth it. After the full treatment prescribed requires a repeat test, but this should be done approximately 2-3 months after the medication. I don't know what tests to give, it is better to seek the advice of a doctor, internist, gastroenterologist, or other specialist.
