GlycA is hypothesized to be a nonspecific measure of global inflammation status. Unlike existing biomarkers of inflammation that are discrete molecular species, such as CRP or inflammatory cytokines, GlycA is a composite biomarker that integrates the protein levels and glycosylation states of several of the most abundant acute- phase proteins in serum. This allows for a more stable measure of systemic inflammation with lower intra-individual variability of GlycA than hsCRP. While guidelines recommend two serial measurements be taken at least two weeks apart when using hsCRP for CV disease risk assessment, only one measurement is necessary for evaluation of a patient's CV risk using the GlycA test.
