Can someone develop and allergy to something they're close to? Specifically, MY pet. Can allergies be that specific?- submitted by Tim B. in St. Louis
Allergy is a genetic disorder that involves reactivity to specific allergens such as dust mite, pollens, and animals to name a few. Unfortunately, allergies can turn on at any time for unknown reasons. It is very common to see a pet owner develop allergy to their pet over time. Relocation of their animal or treatment with medication and possible allergy shots is often necessary.
Is it possible to be allergic to dust but not dust mites? I am on immunotherapy for several different allergens, one was dust. Recently, the FDA has taken away the dust serum and is saying that dust mite serum is the same thing? I was retested for dust mites and didn't have an immediate reaction, but did within 24 hours, a red itchy bump the size of a dime that lasted for several days. The allergy nurse said it was irrelevant because I didn't react right away within 20 minutes. My problem is being symptomatic to dust again since it has been eliminated from my weekly shots. I've been on shots going on two years. Would appreciate any insight or suggestions!- submitted by J. Sullivan
Yes!!! You can be allergic to house dust and not dust mite. House dust is a mixture of many substances including shed human skin, mold, animal hair and dander, fibers, and dust mite and its excrement. The amount of each can vary from home to home. The significance of Late Phase skin test responses to an airborne allergen such as dust mite has long been controversial. Despite the lack of conclusive data, many allergists consider a delayed response to be significant. This is based on the known fact that the allergic response is made up of an early phase [immediate up to 30 minutes] followed by a more prolonged late phase reaction. The late phase typically occurs 4-8 hours after exposure but can occur even later in some circumstances. Based on this data it can be extrapolated that a delayed response up to 24 hours could be relevant.
Every allergist has their own style and protocol as to what they may remove from serum after a retest. Typically I do not remove an allergen that has shown significant reactivity on previous testing.
Finally, If you seem to be more clinically sensitive to dust.... it may be necessary for your allergist to review your allergy serum makeup and increase the individual components (such as dust mite, mold etc.) that you may have lost with the removal of house dust from your serum.
