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.
For a variety of reasons, including preferences of taste and the possibility of food allergies, itâs a good idea to know which foods contain shellfish. Indeed, crustaceans are one of the eight major food allergens, the others being milk, eggs, fish, wheat, tree nuts, peanuts and soybeans. By law, the US Food and Drug Administration requires that any packaged food product with shellfish as an ingredient list the name of the shellfish on the label.
The approximate prevalence of shellfish allergy is estimated at 0.5-2.5% of the general population, depending on degree of consumption by age and geographic regions. The manifestations of shellfish allergy vary widely, but it tends to be more severe than most other food allergens. Tropomyosin is the major allergen and is responsible for cross-reactivity between members of the shellfish family, particularly among the crustacea.
