Reticulin antibody

Sample: Serum

Schedule: Daily (Immunofluorescence) 

Units: Titer

Range: Negative

Remarks: Anti Reticulin antibodies are used in the diagnosis of gluten-sensitive enteropathies.The presence of specific antibodies (Gliadin, Reticulin, and Endomysium) are associated with gastrointestinal disorders related toceliac disease or dermatitis herpetiformis, both caused by sensitivity to gluten. Total restriction of gluten in the diet will control the symptoms, and antibodies in serum is expected to disappear. Wheat gluten is a mixture of polypeptides that are rich in glutamine residues. In the intestinal mucosa the enzyme transglutaminase removes an amino group from the digested peptides either cross-linking with another polypeptide or creating a free glutamate residue. In patients with the type of major histocompatibility complex that presents small peptides with glutamate residues, the antigen-presenting cells in the lamina propria of the small intestine activates the CD4 T cells, resulting in inflammation that causes diarrhea and malabsorption. Autoantibodies to the tissue transglutaminase are a marker of this disorder (called celiac disease).
