You don't.  An allergic reaction to peanuts can include hives, breathing difficulties, anaphylactic shock, and death.  It's much better to avoid exposure to peanuts, than to get a test that is likely to come back negative.

Okay, so I can get a test for it?
user
A test isn't really needed.  People usually have no way of knowing beforehand if they'll have an allergic reaction, and the test may only show positive results for a percentage of those who have a genuine allergic reaction.  Most doctors will advise against taking the test.

Okay, thanks. Is family history important?
