DNA tests can obviously be of a sensitive nature and we are more than aware of this. All our DNA sampling kits are sent out in the post in plain envelopes marked Private & Confidential and with no branding on them, so it will look like a normal letter.
Shellfish Allergy Triggers. Within the shellfish family, it is the crustacean group (shrimp, lobster and crab) that causes the greatest number of allergic reactions. Many shellfish-allergic people can tolerate mollusks (scallops, oysters, clams and mussels). Avoid foods that trigger symptoms.

Here's the truth about shellfish and seafood allergies: 1  Shellfish allergy can occur any time in life. 2  Adults and young adults may suddenly develop a shellfish allergy; it can appear at any age. 3  They may never have had an allergic reaction to shellfish or seafood before, and suddenly have a severe reaction to shellfish.
