"The first principle for the treatment of allergic diseases is detachment from allergens, and many asthmatics have different degrees and different types of allergen allergies, especially after exposure to specific environments."
According to Dr. Wang Ying of the Department of Respiratory and Critical Care Medicine of Beijing Chaoyang Hospital, the accurate diagnosis of allergic diseases is the core of the prevention and treatment of allergic diseases, and the early examination of allergens is carried out to determine whether there is allergen sensitization, which allergen allergies and to what extent, which can help patients take effective measures to avoid them, so as to avoid the onset of the disease.
We can see that with the improvement of everyone's awareness of allergic diseases, allergen detection has also become a popular project in the hospital, and some patients have said as soon as they come up, "Doctors, I am allergic to too many things, you check for me, check me clearly", "Obviously I am allergic to peppers, how can you not find out by doctors?" "After testing negative, why am I still allergic?" "I didn't have allergies at all before, so why am I allergic to pollen now?" ......
There are still a few things to know about allergen testing:
Is the more complete the allergen test, the better? How many kinds of measurement is enough?
Dr. Wang Ying introduced that the general allergen test will first give the patient a total IgE test, which is a means of detecting the total allergic state of the body and is an important sign of allergy. Its value increases, indicating that the patient is in a state of allergy, and if the value is relatively low, the probability of allergy is relatively low. Once it is determined that the patient has allergies, the doctor will conduct further special allergen testing, and the doctor will focus on the test according to the patient's past medical history and contact history.
Patients hope that the allergen detection is as complete as possible, of course, it is understandable, but there are many substances that can cause allergies in the world, organic matter, there are also inorganic substances, and it is unrealistic to want to detect one by one, nor does it meet the economic benefit ratio, in fact, it is not necessary. Even if the hospital allergen testing is carried out comprehensively, it is still a test for common major allergens.
For some patients whose allergies are very severe and it is possible to be allergic to many kinds of things, a more comprehensive allergen detection can be carried out if the patient's financial conditions permit. But this is not the doctor's routine recommendation, many times even if the detection of a clear allergen, the patient is inevitable contact, such as some dust mite allergy patients, dust mites often exist in the bedding, you can not cover the quilt, so the allergen test does not need to blindly seek "full".
Obviously the test is negative, why do I still have allergies?
Just as we said, there are many substances that are easy to cause allergies, even if the doctor has done a test according to your past medical history, a negative can only represent one, the test is limited, it is likely that you are allergic to the substance that has not been detected. Even if all tests are negative, allergic diseases cannot be completely ruled out.
Dr. Wang Ying also reminded that there is also a point involved here, many patients after the allergen test, very happy, clear a certain allergen positive, take it for granted that in the future, they can get rid of these substances without medication. This is true in theory, but in practice it is almost impossible to completely disengage. It can only be said to avoid as much as possible, or try desensitization treatment, and coexist with it in a well-controlled situation, without affecting your own life.
Eggs and milk allergies at a young age, should these substances be avoided for life?
Protein allergies are very common in allergic diseases, for such patients once an allergic reaction occurs, and the test result is positive, then at least in the current state of allergy is to be strictly avoided, is that not to say that you can never eat it later? No, this varies from person to person, and some people will develop tolerance after a while.
Dr. Wang Ying also suggested that for patients with such foodborne allergies, they can re-contact or try to eat again after the allergy stops 3-6 months, if it is found that they are not allergic, it may be possible to gradually induce tolerance in the future, once it is found that there will still be a very serious allergic reaction, it is not recommended to try again, and it is not advisable to contact it.
Allergies are closely related to our immune system, often find that when children are allergic to a certain type of substance patients grow up to no longer be allergic, some middle-aged and elderly patients, with the aging of increasing immune function began to appear allergic diseases, the allergic state is in a dynamic change process.
As an important and necessary test for allergic diseases, correct understanding of allergen testing can scientifically guide the treatment of allergic diseases!
