An allergic reaction to almonds can produce mild symptoms, such as a slight tingling of the mouth shortly after ingesting almonds, to a severe systematic and life-threatening reaction, according to Food-Info. Severe almond allergy symptoms include hives, swelling of the throat, asthma and anaphylactic shock. The severity of a person's reaction to almonds is based on which protein in the almond to which he is allergic.

Almonds are considered a tree nut even though they belong to the Rosaceae family, which includes apples, pears and strawberries, according to Food-Info. Because almonds are present in many forms in processed foods, avoiding almonds can be difficult and requires strict adherence to reading labels. Many people allergic to almonds are also allergic to other tree nuts as well as some fruits from the Rosaceae family and birch pollen. Unless a clear tolerance has been proven to other tree nuts, a person with an almond allergy should avoid them due to possible cross-reactivity. Tree nut allergies typically appear in childhood although some adults can develop the allergy.

Skin allergy tests and Radioallergosorbent food sensitivity tests are the best ways to confirm an allergy to almonds, according to Food-Info. The RAST involves testing a person's blood for sensitivity to certain allergens, notes About.com.
