Abstract: The invention provides compositions and methods for determining GLP-1 analog and/or DPPIV inhibitor response in a subject. In one embodiment, the composition comprises a solid support comprising probes for measuring a biomarker panel comprising, for example, adiponectin, C-peptide, hsCRP, insulin, proinsulin. The simultaneous use of multiple biomarkers with independent classification power will increase the performance of the biomarker panel in characterizing GLP-1 analog and DPPIV inhibitor response. The invention also provides methods of treating a subject (e.g. one experiencing cardiodiabetes) and determining the efficacy of a therapy through assaying the various biomarkers of a biomarker panel disclosed herein.
