My niece just had an allergy test done and with the exception of dust mites, it came back negative. However, she can not eat anything with mustard or mustard seed in it with it causing her throat to swell up and the same seems to go for lactose, but since the allergy test was negative on those items, does that mean she is simply sensitive to those items but not fully allergic? Can someone explain the difference between the two?

An allergy is when the body’s immune system treats something that is normally benign as harmful, and starts attacking it.
Food sensitivity or food intolerance is the body’s inability to properly digest certain foods. Unlike allergies it is not an immune system response.
So in short: allergy = immune system, sensitivity = digestive system.
