<prompt> Anti - T.T.G. antibodies are seen in:Giardia malabsorptionGluten enteropathyLactose deficientBile acid malabsorption  <response>: Anti-endomysial antibodies of the immunoglobulin A IgA type can detect celiac disease with a sensitivity and specificity of 90 and 99, respectively. Serology for anti-T.T.G antibodies was initially repoed to have a higher sensitivity 99 and specificity 90 for identifying coeliac disease. However, it is now thought to have similar characteristics to anti-endomysial antibody. Modern anti-TTG assays rely on a human recombinant protein as an antigen. TTG testing should be done first as it is an easier test to perform
