ELISA: enzyme-linked immunosorbent assay; IFAT: indirect fluorescent antibody test; PCR: polymerase chain reaction; HLA: human leukocyte antigen; ND: not done. ^†Units: (average optical densities of the sample/optical densities of low positive) × units of TTG low positive (specified on the label). ^††DQ8: corresponds to the molecular alleles DQB10302 or DQB10305. ^†††DQ2: corresponds to the molecular alleles DQB10201, DQB10202, or DQB10203. The alleles DQA10201: DQB10202 and DQA10501: DQB10201 are termed DQ2.2.
