In brief: Well... Not so fast.

Allergy testing is not tremendously accurate, especially in kids.
More and more studies and reviews are demonstrating this issue in kids. http://www.medscape.org/viewarticle/756631 this is a recent publication that discusses this issue. Alelrgy tests really only help confirm allergies. So if you had strong symptoms to exact foods and test positive its helpful. Random positives likely arent...

The recommendation now is to NOT just randomly test kids with a huge selection of random possible allergens. This often creates positives that arent and negatives that arent. We are supposed to ONLY test for things that kids seem to react to... Explore this with your doctor before assuming you have a ton of allergies.
Dr. James Glauber
Agree, and this pertains to the tests against inhalant allergens mentioned (cats, dogs, etc.). Obviously one can't fully eliminate exposure to these; rather there are strategies to reduce exposure but they should only be employed if your child has allergic or asthmatic symptoms that appear associated with exposure to these things.

In brief: Blood test allergies

Allergy screening for food by blood testing is unreliable without a good history of having reactions to such food.
If that is not available then food challenges by an allergist in the office is the standard before developing a restrictive diet.

In brief: Hard to say

Blood tests for allergies can be misleading; skin tests are much more accurate.
But the GI tract can suppress some immune reactions, so a positive skin or blood test does not necessarily mean she's allergic. The test results and symptoms she has had need to be interpreted by a trained allergist; "cook-book" medicine cannot be applied in cases of food reactions.
