An allergy to one type of nut may not mean you're allergic to all types.

A new study found nut allergies are being over-diagnosed because many skin and blood tests can't be relied on. 

Researchers looked at more than 100 participants with a known tree nut allergy and found 50% passed an oral food challenge to other tree nuts without a reaction. 

The study looked at allergies to almonds, cashews, hazelnuts and walnuts. 

Researchers remind people they should talk to their doctor before making any changes to their diet.
