I got tested for food allergies the rast method. is this as effective and sensitive as skin prick test to pick up?
A doctor has provided 1 answer
Skin vs. RAST tests: Overall skin testing is slightly more sensitive than RAST testing, especially for indoor/outdoor allergens. If your food RASTs are all negative it is unlikely that a skin test will give you any further information. I use skin testing as original diagnostic test then use serum testing to follow food allergies over time. Clinical history must be taken into account, these tests can be inaccurate.
