Parasites living in the human body cause incomprehensible etiology.It can be skin rashes, honesty, heartburn, nausea, weakness, anemia, joint pain.Special tests should be made to clarify the diagnosis.
Parasites that can live in the human body
Classification of parasites in their images:
- Lamble,
- Opistorchi,
- Echinococci,
- Tokkers,
- Trichinella,
- Askarids.
For some professions (employees of catering institutions, children), in the design of sanitary books are required to analyze the worms.Children carry the same analysis when admitted to kindergartens and a kindergarten or a sport.
- A classical study on the worms living in the gastrointestinal tract is an analysis of crumbs from the rectangle of feces and mucosa.
- But there are several options for more effective blood tests for the parasites, intended and according to their method.
Classical Studies on Worms
A classic research on the worms living in the gastrointestinal tract (gastrointestinal tract), Pinworms, Assarids is the crumbs of mucosa from the rectum of mucosa.However, the disposable analysis of the feces cannot show positive results, so it is advisable to do three times.
- To analyze feces and scraps, the histological coprogram method is used (see the cuts of material under the microscope).The effectiveness of research is about 20%, because the probably less eggs or parasite larvae will fall into the material analyzed.
- Contradictive work for Helminths, simple parasites and fungi in the body are electro-sounding methods.Their essence is to achieve results using the measurements of the bioelectric reactions of active points with electrodes.Special devices are used for this purpose.Many doctors question the research information.
- The most informative examination of parasites is a blood test.
Types of blood tests for parasites
There are several options for blood tests for parasites: designed and according to the method.Each of these methods has its own advantages and disadvantages.Depending on the methodology used, the following types of blood tests are available:
- Elisa or immunophynticna.
- PCR or polymerase chain reaction;
- Hemosaning;
- Serological blood test.
Analyze for Elisa, Antibers and Immunoglobulina
This analysis is based on the level of protective reaction to the body's immune reaction and the occupation of parasites.When a pathogen's collateral or blood is called an external protein, immunoglobulins, is called immunoglobulins, when the human body is in the form of antibodies.
- Using the results of Elisa, you can determine the presence of helmines in the body and their type.The correctness of the study is higher than fecal analysis.
- The method is determined by one or another type of anti-body antibodies, in connection with external antigens and the body's enzyme response.
- Antibars - Antigen shows the existence of infection.
- Elisa's blood test, according to different specialists, has a low level of up to 90% occupation of 60%.
- The advantage of the method, along with high level accuracy, immuno-gutter analysis can be followed by the dynamics of the disease over time.
Blood tests performed for parasites
An analysis for antibodies is similar to these antibodies or called immunoglobulins.
- In general, 5 of them read - igg, iga, igm, igg igd.
- The first four immunoglobulin in practical medicine are important.
Igm is the main marker for the sharp phase of the disease
IGM - Immunoglobulin appears in the sharp stage of the disease shows the beginning of the infection.
- Appear in the blood of the fifth day,
- It is detected by analyzing after 6 weeks.
- Then it starts disappearing quickly.
IGE - Marker, parasite infection indicator
IGE - Immunoglobulin shows the existence of parasites or allergies in the human body.
- is the sign of allergy-related processes,
- It is low in blood, based on mucous membranes, macrophys and basophils,
- Participate in infection with parasites.
Igg - illness and immunity sign
Igg - immunoglobulin appear in the process of disease.
- IGG is also protected from some infections for life, for example, measles, Rubella and others after a treatment.
- Detection of immunoglobulins in the blood say that the body has met with this special pathogen in advance with this infection.
The result of the analysis Devik parss
For the parasites, the following results can be extracted for a combination of blood tests and negativity:
- Lack of infection - all antibodies negative;
- Acute stage-igg (+/-), iga (+ \ -), igm (+);
- Chronic form-igg (+/-), iga (-), iGm (-);
- to be immunity-jig (+), IGA (-), IGM (-);
- Escalation of a chronic disease - IGG (+), IGA (+), IGM (+)
- If the disease is detected and treated, the negative values of all anti-antibodies will be obtained only after only six months after the treatment course in 1-2 years.
Reliability of Elisa's analysis
The Elisa method provides a 90% reliability level that causes ingobunoglobuli with ingbounoglobuli with ingbounoglobuli with ingbounoglobulin with ascarides, Pinworms (Enteriobiosis), ingosars and others.
- You can assign lembles with the value of the level of antibodies in the blood and with a total (OPD) value.
- OPD value has been an infection or that is more than 1,
- There is no lumber with a value less than 0.85.
- If the value is in the interval, it is recommended to repeat the analysis in 2 weeks.
This method is characterized by a number of weaknesses.The analysis allows the level of antibodies developed in the body, neutralization of helmins and determine whether worms are not.
- Therefore, false is possible to achieve positive and false negative results.
- This happens when patients take drugs,
- The parallel with metabolic disorders and current chronic diseases.
Changes in the general blood test, parasite infection
You can indirectly suspect the participation of the occupation by making a general blood test.Because the fact that the worms affect the internal organs, the products of their vital activities include blood circulation by changing the composition.Partial list of the results of the invasion of blood parameters:
- increased hemoglobin;
- Non-unusual indicators of the ESR;
- Excess eosinophils 20%;
- Zhelezia anemia.
If there are no other causes of such devices, it is recommended to include a special blood test for parasites, Elisa, PCR in the diagnostic program.
Polymeraz chain reaction, PCR analysis
The PCR method or polymer chain reaction is considered fundamentally based on molecular diagnostics and is the most up-to-date and accurate for diagnosis in the body of parasites.
- The parasitic life forms consist of DNA and RNA traces.
- The essence of the polymerase reaction is a blood treatment in such a way to copy and promote a concentration that allows foreign organisms to determine the RNA.
Serological Blood Test
At the same time, the analysis is used as a source of data in the blood serum.
- Immologenic antibodies of parasites are being investigated.
- The analysis allows you to determine a large number of parasitic forms, but does not allow to determine the stage of occupation.
- As the IFA method, the cereal analysis is indirect to diagnose.
- If the OPD values are high, it is advisable to add inconvenient analysis.
Diagnosis with a blood scan method
During the hemosites in the parasites, you can define the "live" blood "live" blood, in addition to the worms, in addition to the worms.
How to carry blood testing for parasites
The blood donation for parasites is carried out in a specialized laboratory.For analysis, the blood is taken from the elbow of 3-5 ml and is placed in a dry sterile test tube.Prior to the analysis, it is recommended:
- 8 hours of food;
- In the evening dinner, giving up fat pots and milk;
- Do not take alcohol and carbonated drinks;
- Avoid excessive physical strength, physiotherapy, radiation x -r;
- refuse to take medicine.
- Plenty of drinks nice.
- Conditions for a blood donation to PCR are less stiff, because the saturation rate does not affect the presence of Parasites.
Dates of Analysis
- The results of BMA and Serological tests are given within a week.
- PCR is enough for blood tests and hemosaning.
- As a result of the analysis, you must consult a doctor.
