T1DM patients had higher frequency of GADA
levels were measured in serum by radioimmunoassay (Cent AK anti-GAD, Berlin; cut-off point for positivity: 1.
05, high GADA
titer (n = 9) versus low GADA
titer (n = 19).
At present, the single detection for GADA
is still the only critical determinant of autoimmunity in FT1D patients in Japan.
the Islet Autoantibody Standardization Program (IASP)] for islet autoantibody testing are available for IAA, GADA
, IA-2A, and ZnT8A.

are found at similar rates (70%-80%) as ICA in patients with new-onset T1DM.
We performed the TR-IFMA assay measuring IgM-class GADAs
as a single-label GADA
assay but used biotinylated antihuman IgM antibody (BD PharMingen) instead of biotinylated GAD65.
Recoveries at GADA
concentrations near the diagnostic cutoff were 88-99% for the RBA, 106% for the ELISA, and 89% for the TR-IFMA.
The specificity of GADA
binding was investigated by competitive inhibition experiments using pure GAD65 protein as a competitor.
were determined by a radioligand assay based on [[sup.
Sera pooled from three blood donors served as a negative control, whereas plasma from a patient with high concentrations of GADA
(diluted in negative control serum to give a more suitable concentration) served as a positive control.
