A blood test for parasites, which is a mandatory procedure for anyone who works in healthcare, education, animals, or plans to visit educational institutions. In contrast with studies of the stool, modern blood worms provide a more accurate result to provide an opportunity to assess the level of infection and monitor the effectiveness of the treatment. Carried out research of this type quickly and do not require a lot of time to unravel.
When and where you need to do a blood test for helminthiasis?
Sad medical statistics show that approximately every 3 persons the problem of worms is of vital importance. Household, market, office and educational institutions, unwashed fruits and vegetables, handshakes — all these familiar to every adult and child cases and are the main source of infection. Even if the symptoms do not manifest immediately, and in any case, parasites have a very negative impact on the human body: the cause of loss of appetite, contribute to the development of allergies, pain in the damaged organs, poor digestion, and sometimes can cause death. Depending on this, you need to go on parasites tests for each person (preferably every year).
You can't fuck with the exam, if you are experiencing typical symptoms of helminthiasis:
- sudden weight loss;
- urticaria;
- frequent nausea;
- aversion to food;
- significant decrease in hemoglobin;
- irritability or insomnia in children.
In addition, you can also call on a group of people, which should be every 6-8 months to check the blood. These include in particular:
- persons who live in areas with frequent outbreaks of helminthiasis;
- those of us who work in educational institutions dealing with young children;
- health care workers;
- all caterers;
- 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 of the children, school and pre-school age, which will soon have to attend school clubs. For the investigation of blood parasites, which should be pregnant women, children before the vaccination. In addition, repeated tests must be carried out after this time of treatment against parasites.
IFA as one of the most effective methods of diagnosing
The most popular and reliable analysis of experts today called on the enzyme immunoassay of blood for parasites. The main purpose of these high precision laboratory method for the determination of antibodies to specific types of parasites. The same immunoglobulin (also called antibodies) are a natural reaction of the immune system and are designed to neutralize the negative agent.
To make an accurate diagnosis, and find out what intensity of diseases, parasites, how long does it take the experts to manage using 3 different types of immunoglobulins:
- Class A. Detected in the blood of children or adults, which is about 2-4 weeks after infection. Almost 80% of them are excreted in mucous membranes and only 20% remains in the blood. After treatment, immunoglobulin, And may present not more than a month. If a second test for parasites again detects them, then the disease passed into a chronic form.
- Class M. the Most quickly react to the presence of the parasite. In the blood detected on the 5. the day after infection. However, they do not stay long — up to 2 months, and then gradually displayed. So, doctor, we can conclude that the presence of acute helminthiasis in the moment.
- Class G. Appeared relatively late — after 1 month after helminth infection. However, they are displayed longer than six months. They are used to understand how long a person suffers from helminthiasis.
In comparison with other laboratory methods, ELISA has several advantages, in particular:
- high accuracy;
- the ability to determine the stage of the disease;
- versatility;
- the possibility to use for mass screening of the population;
- fits adults and children.
Enzyme-linked immunosorbent assay appropriate to use to identify these types of helminthiasis, such as:
- giardiasis;
- trichinosis;
- leishmaniasis;
- ascariasis;
- cysticercosis;
- opisthorchiasis;
- echinococcosis and others.
Hemo examination for the detection of parasites
Hemo — scan - one of the most modern tests for parasites in children and adults. With it it is possible to determine the following:
- a special form of the parasite;
- the structure and the number of leukocytes;
- 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 provides a fence only a few drops of blood from a finger. The liquid, which is located on the sterile glass, and then carefully examined under a microscope. The number of increases reaches 1800-2000 times. No need for any additional processing (the use of enzymes, dyes, drainage, etc). In modern clinics the image displayed on the screen, but because the patient has the opportunity to observe the research process, to verify the presence of fungi and helminths. Shocking is, you can figure the larvae of parasites. If necessary, run a photo or video studies.
This is the obvious way, because the information on the state of your health, a patient can learn in 10-15 minutes.
It should be noted that as an independent method for the determination of parasites, hemo scan is not actually used. The fact is that the human body can accommodate different types of parasites with different translations. Not, in any case, the migration of the larvae in the blood. To suspect the presence of worms allows for a reduced number of red blood cells (such as some parasites feed on blood and nutrients), increased white blood cell count (indicates the body is fighting a parasite), dense plasma.
Other methods of diagnosing
If you are using 1. way to identify the bot fails, the doctor recommends additional laboratory investigations:
- Serologic analysis. It also refers to the immunological variants, and ELISA. However, unlike the latter, the first objective is to investigate, not blood and serum. To obtain the information the doctor needs for the use of the reaction between antibodies and antigens. Serological analysis has not been performed for all types of worms, but just the fact that the doctor is suspected. If the human body is the parasite, the specialist will notice that it has a clear reaction.
- PCR diagnostics. Making it possible to determine in which phase of the development of helminth infection and are not recommended for the establishment of all types of parasites. With its help it is possible to find out only whether there is in the human body simply worms. The main task of the technician in this case — the search for the DNA and RNA in the parasite. It does not matter, the parasite is alive or dead. To take to research is the possibility of any material, in particular, urine, blood or stool. For greater reliability of such analyses may give up a few times.
- Vegetative resonance test. The method is based on detecting the resonance between the human body and drug. The latter are information carriers of different types of worms. All the frequency data of each species of parasites was recorded by scientists in 1989, the art (as it is also called the this method) is carried out only in laboratory conditions and has a chance to identify, what is the status on the human immune system in a given period of time. So, with the help of the GARDEN doctor can figure out whether the body is suffering from allergies or is toxic, bacterial, parasitic influence or not.
- A complete blood count. Too high or too low hemoglobin, decreased red blood cell count, an increased number of eosinophils are the main characteristics that allow to suspect the presence of the parasite in the human body.
How to prepare for the study, and how to decipher the results?
The characteristics of the delivery of the analysis depends on which method to use, and what types of parasites are suspected. Usually, blood from the veins, and in some cases (hemo scan) of a finger. Only 10-15 ml of blood for diagnosis.
To get the most accurate information, it is necessary to take into account specific rules of delivery of clinical tests:
- On the eve of the day of blood collection the patient should not consume too much salty, greasy food (because it can change the level of 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 parasites).
- It is better to pass the material on an empty stomach. Allowed in a small amount of clean water.
- It is imperative that you inform your doctor about medications that have been used in the last 2 weeks.
- It is not advisable for a few days before the tests, if you want to use any physiotherapy treatment (including chest x-rays, ultrasound, radiography).
- At least a week before sampling of blood, in order to alcoholic beverages and medications that contain a high concentration of ethyl alcohol.
- Smoking should be abandoned at least 2 hours before testing.
If strong helminthiasis suffer a pregnant woman and the newborn examination is required. Blood taken from the umbilical cord or the placenta.
For research, usually 2-3 days. A little more time (up to 5 days) will have to spend in case the package is to run immunological studies on different types of parasites.
The transcript must be only a specialist. The simplest explanation remains the hemo scanning, and PCR diagnostics. Either the detection of the parasite or its larvae or not.
Difficult situation with the method, which is called IFA. The doctor is obliged to take account of the immunoglobulins of the 3 groups. So, the acute form of the disease can tell you if the combination will be: immunoglobulin M-positive, and class A or G can be positive or negative. On the chronic form of misleading information: immunoglobulin M does not exist, and class A and G, which can be positive or negative.
In this case, if any of the above mentioned tests showed a positive result for the delay the treatment of helminthiasis is worth it. After the full prescribed during treatment requires repeat testing, but this should be done approximately 2-3 months after the medication. Not knowing what tests they must go, it is better to consult a doctor-internist, gastroenterologist or other experts.
