A blood test for the parasite is an obligatory procedure for everyone who works in health care, education, animals or going to visit colleges. In contrast to studies stool, modern blood worms to give the more accurate result, provide an opportunity to assess the extent of infestation and to monitor the effectiveness of treatment. Perform studies of this type quickly and do not require much time to interpret.
When and to whom you need to pass a blood test for helminthiasis?
Sad medical statistics suggests that about every 3 persons to the problem of worms is critical. Household transportation, office and educational institutions, unwashed fruits and vegetables, handshakes — all these familiar to every adult and child cases and are the main source of infestation. Even if the symptoms do not manifest themselves immediately, and in any case, the parasites have a very negative effect on the human body: causes of poor appetite, promote the development of allergies, pain in the damaged organ, poor digestion, sometimes causing death. In view of this, you need to transfer the parasite test for each person (preferably annually).
You can't fucking research, if it looks like a typical symptoms of helminthiasis:
- sudden weight loss;
- hives;
- often nausea;
- aversion to food;
- the sharp decline in hemoglobin;
- irritability or insomnia in children.
In addition, you can also call a group of people which are necessary every 6-8 months to check blood. These include, in particular:
- persons who live in areas with frequent outbreaks of helminthiasis;
- those who work in schools and with young children;
- medical professionals;
- all the maintenance services;
- persons who work with animals, as well as their family members (veterinarians, workers in meat processing plants, shepherds, breeders, circus workers and zoo, etc.).
In addition, the blood worms have to pass all the children of school and preschool age, which soon will have to participate in school clubs. To study the blood parasites would be pregnant women, children before the vaccination. In addition, repeated tests should pass after this course of treatment against parasites.
IFA-one of the most effective methods of diagnosis
The most popular and reliable analysis experts today called enzyme-immunoassay for the detection of blood parasites. The main purpose of this high-precision laboratory-a method to identify antibodies, in particular the type of parasite. The same immunoglobulin (also called antibodies) are a natural reaction of the immune system, and is intended to neutralize the negative agent.
To make an accurate diagnosis, and find out what the intensity of the disease the parasite, how long it takes, experts to manage using 3 different types of immunoglobulins:
- A-class Detected in the blood of children or adults is approximately 2-4 weeks after infection. Almost 80% of them are excreted in the mucus membranes and only 20% stays in the blood. After treatment, immunoglobulin, And may present not more than a month. If the second test for parasites again detects them, then the disease has shifted to chronic form.
- Class M. most quickly respond to the presence of the parasite. In the blood is detected 5. day after infection. However, they do not stay long — up to 2 months, and then gradually appear. Thus, the doctor can conclude that the presence of acute helminthiasis at the moment.
- Class G. Appear relatively late — after 1 month after helminth infection. However, they are visible longer than six months. They are used, in order to understand how long the person is suffering from helminthiasis.
Compared to other laboratory studies, ELISA has several advantages, in particular:
- high accuracy;
- the ability to determine the stage of the disease;
- versatility;
- the possibility of using mass screening of the population;
- suitable for adults and children.
Enzyme-linked immunosorbent assay appropriate to use to identify these types of helminthiasis:
- giardiasis;
- trichinosis;
- leishmaniasis;
- ascariasis;
- cysticercosis;
- opisthorchiasis;
- echinococcosis and others.
Hemo-scan to detect parasites
Hemo — scan - one of the most modern tests for parasites in children and adults. With its help it is possible to identify the following:
- a special form of the parasite;
- the structure and the number of white blood cells;
- the number of red blood cells;
- the degree of viscosity of the blood;
- the immune system;
- the presence of fungi and viruses.
Unlike ELISA, haemo scanning to provide a fence just a few drops of blood from a finger. The liquid is placed into a sterile glass, and then carefully examined under a microscope. The amount of growth achieved by 1800-2000 times. You do not need any other treatment (use of enzymes, dyes, drainage, etc.). In modern clinics the image displayed on the monitor, but because the patient has the opportunity to follow the research process, to check for the presence of fungi and helminths. Shocking can be a picture of the larvae of the parasite. If necessary, perform image or video of the investigation.
It is the Express method, because information about the state of his health the patient can learn in 10-15 minutes.
It is worth noting that as an independent method to identify the parasite hemo scan is not actually used. The fact is that the human body can accommodate different types of parasites of various localization. Not in every case, the migration of the larvae in the blood. Suspecting the presence of worms using a smaller amount of red blood cells (like some parasites feed on blood and nutrients), increased white blood cell count (indicating the body to fight against parasites), dense plasma.
Other methods of diagnosis
If you use method 1 to identify the bot fails, the doctor will recommend other laboratory tests:
- The Ce analysis. Also refers to the immunological options, and ELISA. However, unlike the latter, the first objective is to explore, not blood, and serum. In order to obtain the information, the doctor must use the reaction of antibodies and antigens. Serological analysis is not to make all kinds of worms, but just the fact that your doctor has reason to suspect. If the human body has parasites, experts see a clear reaction.
- PCR-diagnostics. Makes it impossible to determine the stage of development of helminth infection and is not recommended for the establishment of all sorts of parasites. With its help it is possible to find out only whether there is a human body in simple worms. The main task of the doctor in this case — the search-the DNA and RNA of the parasite. It does not matter, the parasite is alive or dead. Take research is possible, any material, in particular, urine, blood or feces. Greater reliability of such analysis can give a couple of times.
- Vegetative resonance test. The method is based on the identified resonance between the human body and the drug. The latter are information carriers of different types of worms. All frequency data for each species of parasites was recorded by scientists in 1989, the art (also called this method) has been done only in laboratory conditions and provides an opportunity to identify what is the status of the human immune system in a certain period of time. So, with the help of, SEE a physician can determine whether the body is suffering from allergies, whether it is toxic, bacterial, parasitic effect or not.
- Complete blood picture. Too high or too low hemoglobin, decreased red blood cell count, increased the number of eosinophils are the main features that allow to suspect the presence of parasites in the human body.
How to prepare for research, and how to interpret the results?
Features delivery of the analysis depends on which method you need to use, and what type of parasite is suspected. Usually the blood is from a vein, and in some cases (hemo scan) of a finger. Only 10-15 ml of blood to confirm the diagnosis.
You can get the most accurate information, it is necessary to observe certain rules for the delivery of clinical tests:
- On the eve of the day the blood sample of the patient is not allowed to consume too much salty, fatty food (because it can change the white blood cells); 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 parasite).
- It is better to move the material on an empty stomach. Allowed a small amount of clean water.
- It is essential to inform your doctor of all the medicines, which were used during the last 2 weeks.
- Not recommended for a few days before the tests to use any physiotherapy treatments (including chest x-rays, ultra sound, x-ray).
- For at least a week before blood sampling to give up alcoholic beverages and medicines, which contain high concentrations of ethyl alcohol.
- Smoking should be avoided for at least 2 hours before testing.
If a strong helminthiasis suffer from pregnancy, and the newborn examination is necessary. Blood is taken from umbilical cord or placenta.
Research, usually 2-3 days. A little more time (a maximum of 5 days) spend in the event that the package is to run immunological studies of different types of parasites.
Transcript should only be a specialist. The simplest interpretation is still hemo scanning, and PCR-diagnostics. They either detect the parasite or its larvae or not.
Difficult situation, which is a method, which is called IFA. The doctor is obliged to take into account immunoglobulins 3 groups. So, the acute form of the disease can tell you if there will be a combination of: immunoglobulin M is positive, and class A or G can be positive or negative. About the chronic form of misleading information: immunoglobulin M does not exist, and class A and G may be positive or negative.
In that case, if the above-mentioned tests showed a positive result, delaying the treatment of helminthiasis is not worth it. When the whole prescribed course of treatment requires repeated testing, but this should be done approximately 2-3 months after the medication. Don't know what test you need to pass, it is better to consult a doctor-internist, gastroenterologist or other experts.
