The Quantiferon Tuberculosis Test is a fairly accurate diagnostic method. Many in Russia are interested in how such a study can be done. It will also be useful to find out how the procedure is carried out, where to go in order to receive the corresponding service. In fact, there is nothing difficult. Especially if a citizen expects to contact private clinics. What you need to know about the quantiferon test? About all the features of the process - below.
Tuberculosis is ...
The first step is to understand what kind of disease is involved. Perhaps, without additional research, it will be possible to do for an accurate diagnosis?
Tuberculosis is a serious disease that affects many organs in the body. The infection is transmitted by airborne droplets or through objects used by the infected person. It is easy to get infected, but not to recover.
As a rule, tuberculosis at the initial stage does not manifest itself. And only in the already difficult to treat forms it becomes noticeable. Therefore, the population is offered a quantiferon test for tuberculosis. But what is it? What information should citizens be familiar with about the procedure?
Test definition
What is this all about? The Quantiferon Tuberculosis Test is a modern and accurate laboratory blood test that allows you to identify the specified disease in the body. Of the shortcomings, we can only distinguish that it does not show the type of tuberculosis infection.
What replaces the quantiferon test? Mantoux and Diaskintest. It turns out that this study is an analogue of the skin diagnosis of tuberculosis. Unlike the Mantoux or Diaskintest reaction , such a procedure does not imply the introduction of any drugs into the human body.
The test is based on the search for special gamma interferon. It appears in people who have experienced tuberculosis. But all the other citizens in the body do not have these particles.
Procedure
How is the study conducted? For patients, everything is simple: venous blood is taken from them, which is then poured into 3 tubes. Next, the laboratory will search for gamma interferon. The triple search is connected with the fact that during any study it is necessary to take into account the probability of a false positive or false negative result. Therefore, the quantiferon tuberculosis test is notable for its accuracy. There is a probability of error, but it is scanty.
Blood is taken on an empty stomach. Both in children and in adults. Since the last meal, at least 8 hours should pass. Otherwise, an inaccurate result is highly likely.
It is easy to guess that a positive reaction will be in patients. If a person has not experienced tuberculosis, then the test will be negative. This fact must be taken into account. Repeated diagnostics can be done immediately after receiving the first results. This advantage is often emphasized.
And if the vaccine
Many are interested in whether a false-positive result could be obtained during the study if a BCG vaccine was given to a person. Doctors claim that such a vaccination is carried out immediately after birth. And she does not give any false results in research. That is, the quantiferon tuberculosis test only responds to gamma interferon. And he, as already mentioned, is secreted in the blood of an infected person.
Therefore, do not be afraid to conduct this study if a person has had a BCG vaccine. Although doctors do not recommend giving blood for analysis earlier than a month after vaccination. This is an additional insurance that minimizes the error of the results.
Surrender Issues
Is the quantiferon test interesting? Where to make it? This question interests many citizens. Why?
The fact is that in Russia, for the mass check of children and adults for the presence of tuberculosis, a slightly different diagnosis is used. In 2016, to determine this infection, the population is offered:
- Diaskintest
- Mantoux reaction;
- X-ray
But the quantiferon test is not. It turns out that this research cannot be conducted in the state polyclinic. Where then? Where to go for help if you don’t want to inject some drugs with tuberculosis proteins under your skin? There is an exit!
Private clinics
Where to go to conduct a quantiferon test? Where to do this study? It is already clear that such a technique is not welcomed in state clinics. Moreover, it was not recognized as a national type of definition for tuberculosis in humans. Therefore, you will have to look for other places to take the test.
Fortunately, modern citizens can do a similar study without any particular problems. It is enough to contact private clinics. Any private laboratory in a city offers a quantiferon test for tuberculosis. However, for a fee, you can pick up any other study. For example, such that it shows the type of infection that lives in the body.
About specific clinics
But where exactly do they most often suggest asking for help in this area? Each city has its own private clinics and laboratories. Therefore, to name any specific places is very problematic. You can pay attention to the largest research medical centers in Russia. They usually serve both children and adults.
What do people offer? You can have a Quantiferon test for tuberculosis at Invitro. This laboratory will give the result with maximum accuracy in just 3-4 working days. Branches of the organization are opening in Russia. At the moment, a similar study is proposed:
- in Moscow;
- St. Petersburg;
- Kaliningrad.
But the possible scenarios do not end there. In each city, as already mentioned, you can go to any private laboratory in which blood is taken for analysis in principle. And with a high degree of probability it is possible to do the corresponding research there.
In addition, you can contact the following organizations for help:
- Hemotest. A quantiferon tuberculosis test is performed here in a week.
- Helix There are branches of the laboratory in many cities of Russia.
- "LabTest". Clinic of St. Petersburg, which offers a wide range of services.
The list of laboratories does not end there. They can be continued indefinitely. It is recommended to contact the registry of a private medical center in the village for more accurate information about the quantiferon test. Most likely, almost every such institution offers this kind of service. And this is not surprising. In Russia, the mentioned study is an exclusively paid option.
Moscow and the test
Quantiferon test in Moscow is done not only in private centers. There are at least 2 organizations that do not belong to private laboratories, but at the same time carry out the specified diagnostics.
Where exactly can I go? At the moment, the quantiferon test for children in Moscow (as well as adults) is carried out:
- at the Research Institute of Tuberculosis at the RAMS;
- Research Institute of Phthisiopulmonology at Moscow State University Sechenov.
It is worth paying attention that in the indicated places the service is paid. And the scientific research institutes do not produce blood sampling. So, first you need to collect blood from a vein in several (2-3) tubes, then take it to the laboratories of these organizations. From the moment of collection no more than 120 minutes should pass.
Peter
And where can I get the quantiferon test for tuberculosis in St. Petersburg? In addition to private clinics, it is possible to take blood for analysis to research institutes. Where exactly?
At the moment, this procedure is carried out at the St. Petersburg Research Institute of Phthisiopulmonology. The organization is located on Ligovsky Prospect, 2/4. The service is paid, blood sampling is not performed here. Accordingly, it is necessary to bring the test tubes to the laboratory on their own.
Of course, excluding private clinics is also not worth it. But from state institutions in St. Petersburg, only the Research Institute of Phthisiopulmonology provides the studied service for a fee. In ordinary clinics, this procedure is not performed. This must be considered by everyone. Now it’s clear that you can do a quantiferon test for tuberculosis in Invitro and other research laboratories. They, as already mentioned, are enough in every city.
Advantages and disadvantages
But what else is worth paying attention to? Why was such an accurate test not recognized as the official method for diagnosing tuberculosis in Russia? And is it possible to believe the information obtained as a result of such an examination of the body?
You should not be afraid of this procedure. It is not recognized at the state level only because the cost of mass diagnostics is too high. Therefore, in private clinics, the quantiferon test (in Moscow or any other city - this is not so important) costs 1,500-3,000 rubles on average. Not the cheapest procedure. But it is accurate.
What are the pros and cons of it? Among the advantages are:
- quick result;
- high accuracy (up to 99%);
- there is no reaction, as on BCG;
- security;
- lack of side effects;
- no contraindications.
But research flaws also occur. These include:
- high cost of diagnosis;
- done mainly in large cities;
- does not allow to determine what form of tuberculosis is occurring.
Is this study worth it? Everyone decides for himself. In any case, the quantiferon test for tuberculosis is an excellent substitute for the Mantoux and Diaskintest reactions. Many people try to donate blood to check the body for the presence of Koch's bacillus. Therefore, you can look at the studied study. Especially if the body had a negative reaction to injections and other injections. It is likely that the quantiferon test is suitable for a child or adult.
