The evaluation of antibodies for T1DM showed a significant increase in zinc transporter 8 and a slight increase in anti‐islet‐cell antibodies, which included zinc transporter 8 Ab 413.6 U/mL (> 15 positive), anti‐insulin Ab 3.3 U/mL (>2.4 positive), glutamic acid decarboxylase Ab 4.8 U/mL (>10 positive), anti‐islet cell <1/10 (negative). Here, INS is linked to type 1 diabetes mellitus.
