In brief: Skin test or labs
The most sensitive test to diagnose allergy is an allergy skin test performed by an allergist.
These tests will be interpreted in the context of your medical history and symptoms (for example, what time of the year and with what exposures you have symptoms). Sometimes allergy blood tests can be used, but they are not as sensitive at picking up allergy as are the skin tests.

In brief: Blood and/or skin
If your pediatrician suspects allergies, a blood test can be ordered.
If your child is severe, referral to an allergist to do skin testing is a second option. You can also carefully observe your child following introduction of a new food.

In brief: Blood or skin tests
Babies and children can be tested for allergies by a blood test (any regular lab can do it) or by a skin test (usually done by an allergist).
There are hundreds of items that can be tested for, to see if an allergy exists to such items. So, a parent needs to talk with the doctor first, to figure out which items are suspected of causing allergies, and then to test for those few (10-25) items.

In brief: Allergy test
If you have allergies, your body produces an antibody that is specific to your allergic triggers.
Your doctor or allergist can order a blood test or do a skin prick test to determine if you are allergic to a particular food/environmental allergen.

In brief: Skin, blood, observe
Skin testing (scratch testing) is more complete, but harder until kids are a bit older, 2 or so.
Newer blood tests are easier, but less extensive. The older, but still effective, "careful observation" is still very helpful!

In brief: Skin testing is best
Allergies are best tested with skin tests.
Blood tests like immunocap and rast testing are alternatives but are not as accurate. Skin tests are usually preformed by an allergist.
