PROTIA Food IgG 96 is an in vitro diagnostic test that semi-quantitatively detects food-specific IgG (sIgG) antibodies in human serum using advanced immunoblotting technology. It enables the testing of dozens of allergens simultaneously, providing a reliable solution for diagnosing chronic food allergies.

Unlike acute IgE-mediated allergies, chronic food allergies develop over hours or days due to prolonged IgG immune responses. These responses result from allergens crossing the digestive walls, forming immune complexes that trigger inflammation, causing symptoms such as gastrointestinal pain, nausea, and diarrhea. Avoiding specific allergens through elimination diets can effectively alleviate these symptoms, making IgG detection crucial for diagnosis.

The PROTIA Food IgG 96 kit uses enzyme-linked immunoassay principles with nitrocellulose membranes embedded with allergens in parallel, allowing efficient multiplex testing. Food-specific IgG binds to allergens, followed by a reaction with biotin-coupled antibodies and streptavidin-alkaline phosphatase. A color reaction is developed, and its intensity is analyzed to provide accurate results.
