Unlike enzyme‐based strips for on‐the‐spot measurements of metabolite diabetes biomarkers, laboratory‐based analysis of T1D‐based analytes, such as insulin, cortisol, C‐peptide (a marker of endogenous insulin production), and insulin antibodies (present in most people who receive exogenous insulin; such antibodies can lead to higher circulating insulin levels). Here, INS is linked to diabetes mellitus.
