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.
If you have a family history of food allergies, your chance of developing a shellfish allergy is much greater than if neither of your parents is allergic to any foods. Your allergic reaction to shellfish is the result of your immune system misidentifying shellfish proteins as dangerous substances. When you consume a shellfish allergen, your body releases antibodies, which in turn release chemicals that cause a variety of allergic symptoms.
