Im allergic to mold.. i had an allergy test as a kid. i just was eating some bread and went to grab another pice and is had mold on it. can i have an allergic reaction? or should i be worried about this?

I would not depend on an allergy test as a kid to represent the allergy issues of an adult. At most it is a guide. Mold is also not one thing. There are many separate families of mold, most of which cause few problems to adults. If interested get re-tested. Blood tests are available that can indicate a persons' dangerous allergies that they must avoid.
