<s>[INST] Hi, I have been experiencing whizzing in my chest for quite some time. have met several physicians & ENT specialists but not quite satisfied with the medication. During my recent meeting with a physician he has advised to undergo a allergy test to undermine any problem in the lungs or to identify the allergy due to which the whizzing or acidity may be occuring. would like to know which is this test & where can it be conducted? I found that there is a blood test which can determine the allergy a person can be suffering, is this test recommended? any other test for lung functionining? [/INST] Hello.Thank you for asking at HCM.There are various types of allergy tests for identifying the substances one may be allergic to.The best tests to identify allergies are skin prick tests for allergens. These tests are performed only at good allergy centers/departments and it is very important that they are interpreted by allergy specialist.There are many types of blood tests available for allergies which detect Specific IgE for particular substances. However, good quality tests for allergies are very expensive. Other blood tests many times yield confusing results, i.e. showing allergy towards one is not really allergic!!Also, I don't suggest my patients "panel testing" for allergies, it yields confusing results.I would suggest an Allergist-Immunologist who, after detailed asking about your symptoms, region, environment, will choose type of allergy tests for you. Hope above information will be helpful to you.Should you have any further query, please feel free to ask at HCM.Wish you the best of the health.Thank you & Regards. </s>
