Is AllergieCheck | IgE-Antikörper Test useful for Blutzucker?

The AllergieCheck (IgE antibody test) is not useful for assessing blood sugar levels. IgE antibodies are specific to allergic reactions and have no direct link to glucose metabolism. Blood sugar is regulated by hormones like insulin and glucagon, not by immunoglobulin E. Some companies market IgE tests as part of 'comprehensive wellness panels,' but there is no robust scientific evidence that IgE levels provide meaningful information about blood sugar or diabetes risk. For blood sugar management, established methods such as fasting glucose, HbA1c, or oral glucose tolerance test (OGTT) are required. Using an IgE test for this purpose is misleading and could lead to false conclusions or unnecessary allergen avoidance. Evidence: marketing/unclear.
