Coconut allergy is relatively very rare. Coconut is a very different plant from peanut or tree nuts, each contains a single seed, which is partly liquid (the coconut milk) and partly solid (the coconut meat). Allergic reactions to eating coconut have been reported, but are relatively rare. Traditional allergy tests utilize the Skin Prick method (also known as a Puncture or Scratch test) to determine whether an allergic reaction will occur by inserting possible triggers into your skin using a needle prick or blood allergen specific IgE testing to coconut.
