Lipid Panel With GlycA (Inflammation) and Diabetes Risk Index (DRI)
Use
The Lipid Panel with GlycA and Diabetes Risk Index (DRI) is designed to assess both lipid profiles and inflammation status within individuals. GlycA serves as a composite biomarker that integrates protein levels and glycosylation of acute-phase proteins, providing a stable measure of systemic inflammation with lower intra-individual variability compared to traditional markers like hsCRP. The DRI score, ranging from 1 to 100, uses NMR spectroscopy to gauge the risk of developing type 2 diabetes by analyzing lipoprotein particle size, insulin resistance indices, and levels of branched-chain amino acids. This test ultimately aids in stratifying cardiovascular and diabetes risks, particularly for individuals who are normoglycemic or prediabetic.

Not provided.
Limitations
LDL cholesterol will not be calculated if triglyceride levels exceed 800 mg/dL. Significant variances in GlycA readings arise from differences in specimen types (e.g., EDTA plasma vs. serum), and hemolysis may lower GlycA by more than 10%. DRI results from plasma specimens are typically eight points lower than those from serum, necessitating context consideration. High triglyceride values in frozen samples may decrease by more than 10%. This test's performance characteristics are not cleared or approved by the FDA.
