A SPECIAL NOTE ABOUT LIMITATIONS TO ALLERGY TESTING WITH IMMUNOCAP:
For more information about our allergy testing, and how to interpret results, please take a moment to read our Allergic Testing Information page.
Since ImmunoCAP testing measures antibodies that have been produced in response to exposure to allergens, it is possible for a patient to be allergic to a substance and yet have a negative result on the test because they haven’t been recently exposed to that allergen. And by not having any recent exposures, they may not have a significant amount of IgE antibody circulating to that substance, and may have a false negative test result.
This is especially true in food allergies, where people avoid foods that they may have an allergy to. For example, Joe hasn’t eaten shrimp in years, since he had an allergic reaction to it. Therefore, he probably doesn’t have much (if any) IgE antibody directed at shrimp circulating in his bloodstream. So if Joe gets tested via ImmunoCAP, he may show no allergy to shrimp, even though it is likely he is allergic to shrimp.
The case is somewhat different with respiratory allergens. Since these substances are airborne there is simply no way for people with allergies to avoid exposure, provided the allergens are in the air. In other words, as sufferers of seasonal allergies well know the amount of allergens may fluctuate, dependent on the time of year. So the same reasoning holds true with someone who wants to see how allergic they are to say, dogs: if that person hasn’t been in close contact with a dog in a while, then they may not have any Dog Dander IgE, and show a falsely negative dog dander test. Similarly, it isn’t very helpful to test for pecan pollen in the middle of winter, when there is little in the air.
So if you plan to undergo ImmunoCAP testing, it is best to do so when you are having allergic symptoms that you think may be related to whatever it is you wish to be tested for. So if your local news says that cedar pollen is sky high in your area and you are having significant respiratory symptoms, then that would be the perfect time to consider getting ImmunoCAP testing, to see if and how allergic you really are to cedar.
