This allergy test uses a blood sample to determine if you are allergic to Seven common Nut/Seed allergens: AlmondCashew CoconutHazelnutPeanutPecanSesame SeedDid you know: Allergic reactions can be caused by ingestion, skin contact, and even inhalation. Peanut and tree nut allergies typically develop during childhood and are usually lifelong. Peanut and tree nut allergies are two of the most common--and often severe--food allergies. In the case of peanut and tree nut allergies, the body sees the nuts as a toxin, rather than a food. The immune system reacts by releasing histamines and antibodies to fight the toxin, causing symptoms such as swelling, rashes, throat swelling, gastrointestinal issues (abdominal pain, nausea, vomiting, diarrhea), and more. Peanut allergies have been known to cause some of the most severe allergic reactions of all food allergies, including anaphylaxis and even death. Symptoms often appear almost instantly or within minutes of contact with the nut and can last anywhere from hours to weeks. Traditional allergy tests utilize the Skin Prick method (also known as a Puncture or Scratch test) to determine whether an allergic reaction will occur by inserting possible triggers into your skin using a needle prick. If you are allergic to the substance, you are forced to suffer through your body's reaction to the allergen.
