Food Allergy Awareness: Day 1
Food Allergy Awareness Week:
How was Squid officially diagnosed with food allergies? Don’t they have to poke him all over his back? OUCH!
Yes, most allergies are diagnosed with a skin test but at Squid’s age they chose to do RAST.
RAST (radioallergosorbent test) is a blood test done in a laboratory. It is used to test a sample of blood for antibody to a specific food. While more costly and less sensitive than skin testing, RAST is particularly useful when eczema and other skin conditions make skin testing difficult. It also may be used to confirm a diagnosis when there is a risk of an anaphylactic reaction to skin tests.
