Gluten & Casein Peptides Test is an advanced analysis that uses liquid chromatography–tandem mass spectrometry (LC-MS/MS) to determine the levels of specific peptides derived from gluten and casein in the body. This test is important for individuals with health conditions related to food reactions, such as gluten sensitivity or intestinal inflammation, as well as for some individuals with autism spectrum disorders. The test detects peptides that may negatively affect health, helping to identify the need for dietary adjustments. By assessing the presence of these peptides, physicians can guide patients toward more suitable dietary choices, which may help improve symptoms and enhance overall health. This analysis is considered a valuable tool in modern medicine for understanding how certain foods affect biological processes in individuals.
