Algorithms in diagnosis of celiac disease (N = 11)
Measurement of total IgA precedes determination of IgA class antibodies	5 (0.45)

anti-tTG = antibodies against tissue transglutaminase. ELISA = Enzyme-linked immunosorbent assay. FEIA = Fluorescence enzyme immunoassay. MIA = Multiplex bead immunoassay. anti-DGP = antibodies targeting deamidated gliadin peptides. EMA = anti-endomysium antibodies. IIF = Indirect immunofluorescence. AGA = antibodies against native gliadin.
