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.
Shellfish allergy is the most common food allergy among adults in the United States. It's actually much more common in adults than children: about two percent of American adults have a shellfish allergy, and only 0.1 percent of children have the condition. Unlike many food allergies, shellfish allergy is more likely to develop in adulthood than in early childhood. The majority of people who have shellfish allergy have their first reaction as adults. Once you develop a shellfish allergy, it tends to be severe and lifelong.
