Q&A: Are Blood Tests Always Right at Determining Allergies?
Question by ? Alice ?: Are Blood Tests Always Right at Determining Allergies?
I recently had a blood test which stated I was allergic to cats, dogs and grass.
I know for a fact that grass doesn’t bother me, and I’m only allergic to some dogs.
I break out in really bad, red, itchy rashes around guinea pigs and horses, and become really sneezy. Also, lots of skin products give me a big itchy rash, and sunblock, and plastic carrier bags do the same.
Is it possible that the blood test was wrong?

Well with the animals, I know that it can vary from species to species since it’s only the animals dander that you are actually allergic to and some produce less dander than others. Even those that have more, if they are groomed alot, it will reduce the amount present so that they bother those that are allergic less. The grass is probably due to something that the plant expels like pollen too and if that is so, it would only be at certain times. It might very well be for certain varieties too and that the test is just yielding an “overall” result. You would have to ask your doctor these specifics.
False-Positive. Sure it might be possible. Ask the doc about that too. You already seem to know more about your allergies than they do!
