While there is no specific test that can determine whether or not you are allergic to the anesthetic (or at least there are not tests that are routinely used for most people), there are a few questions that are routinely asked that can help you to know what your risk is. Your doctor
will ask you whether or not you have had reactions in the past, or if anyone else in your family has had similar reactions. If that is the case, he or she may change the course of treatment or recommend different therapy or additional testing. For most people, however, it is so rare that it does not require testing beforehand (similar to the risk of having an allergic reaction to a bee sting, which most people aren't tested for unless there are extenuating circumstances). The best thing for you to do is to speak with your doctor to make sure that you don't have any of the risk factors that might indicate that your doctor should alter your course of therapy. If he or she has further questions after that, or if you have further questions, you can always get a second opinion
or speak to an allergist. Please speak to your doctor.
