Testing is guide: Blood or skin testing both may not correlate 100% with your personal response to a food item. A blood test showing you have high IgE to any food should be respected, since that suggests a dangerous full blown anaphylaxis risk if exposed. A food diary and food challenges based on such testing can help you define your "safe" list, but be aware that can change over time.
