This Clam Allergy test measures the IgE antibody levels in a blood sample to detect a shellfish allergy. Clams are shellfish from the Veneridae (Venus clam) family, found globally in freshwater and marine environments. Clams contain lean proteins, healthy fats (omega-3 fatty acids), and minerals (iron and zinc). Clams may also help boost your immunity, aid weight loss, and promote brain and heart health. Due to their several health benefits, many people eat clams as part of their daily diet.
Clams may be prepared and eaten in several ways, such as:
- Raw
- Steamed
- Boiled
- Baked
- Fried
- Served in a sauce or chowder
Although a shellfish allergy is one of the most common food allergies, an allergic reaction is caused mainly by foods like shrimp, crabs, lobsters, prawns, or crawfish. An allergy to clams is uncommon; individuals with hypersensitivity may experience mild to moderate allergic symptoms upon ingestion. Consumption of clams may activate a response in the immune system. During this response, the body will view certain substances as harmful and produce IgE antibodies to combat these invaders. These antibodies will trigger the release of the histamine chemical, which causes the symptoms associated with an allergic reaction.
Allergic reactions may vary from mild or moderate to severe and differ for each individual. An individual may experience allergic reaction minutes to a few hours after exposure to an allergen. An individual allergic to clams may experience the following symptoms:
- Tingling sensation in or around the mouth
- Swelling
- Abdominal pain
- Nausea or vomiting
- Diarrhea
- Itching, hives, or eczema
- Congestion
- Trouble breathing or wheezing
- Lightheadedness
An extreme, possibly life-threatening allergic reaction is known as anaphylaxis and can occur in the most severe cases. An anaphylactic response requires immediate medical attention. Signs or symptoms of anaphylaxis include:
- Rapid or increased pulse
- Swollen throat or lump making it difficult to breathe
- Low blood pressure
- Extreme dizziness or loss of consciousness
