No: Tests must be ordered specifically for food allergies. Even then the results must be correlated with the clinical findings. A complete blood test focuses only on the number and types of cells measured and has nothing to do with measurement on their functions. Food allergy can be detected by prick skin testing or ImmunoCap IgE blood test- neither is fool-proof.

Specific test: Routine blood tests do not include tests for specific food or other allergens. "Shotgun" testing for a bunch of foods without a thorough history to match the results is NOT recommended because there are so many false positive results which could lead to unnecessary avoidance. Allergists are specifically trained and experienced in this matter.
