They provided feedback on the ease, convenience, and painfulness of blood spot collection. Islet antibodies were measured in blood spots by antibody detection by agglutination PCR (ADAP) or multiplex enzyme-linked immunoassay (ELISA), and in serum by radioimmunoassay (RIA) or ELISA.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Using serum RIA and ELISA to define antibody status, 50 antibody-negative (Ab\n                      <jats:sup>neg<\/jats:sup>\n                      ) and 47 antibody-positive (Ab\n                      <jats:sup>pos<\/jats:sup>\n                      ) participants enrolled, of whom 43 and 47, respectively, returned testable blood spot samples.
