Casein, IgG
Understanding Casein, IgG
What is Casein, IgG?
The Casein, IgG test used to check for sensitivity or intolerance to casein, a protein commonly found in dairy products such as milk, cheese, yogurt, and butter. This test is often part of broader food intolerance tests that assess IgG levels for various foods. Unlike a true milk allergy that triggers an immediate immune response (IgE), casein intolerance involves a delayed immune reaction (IgG), which can lead to symptoms like bloating, abdominal discomfort, skin rashes, headaches, or fatigue. These symptoms may appear hours or even days after consuming dairy, making it difficult to link them directly to food intake. This test is typically recommended for individuals who suspect dairy intolerance or have a family history of food sensitivities. By measuring the immune system’s response to casein, it helps identify whether casein may be a contributing factor to ongoing symptoms. The results can guide doctors in recommending appropriate dietary changes to manage symptoms effectively and improve overall well-being.
What does Casein, IgG measure?
The Casein, IgG test detect Immunoglobulin G (IgG) antibodies specifically directed against casein proteins. This test is a highly precise and reliable method used to detect the body’s immune response to casein. An elevated IgG level indicates that the immune system has identified casein proteins as potential threats, triggering a delayed hypersensitivity reaction. It is important to understand that this test doesn't diagnose allergy. It's more related to food sensitivities or intolerances, which are different from allergies and can be caused by a variety of factors, including difficulty digesting or metabolizing certain food stuffs. In contrast, food allergies are usually immediate and IgE-mediated and tested by other tests which measure allergen specific IgE. Identifying such immune responses can help pinpoint food triggers, enabling doctors to recommend personalized dietary changes.
