As the global burden of diabetes continues to rise, there is an urgent need for biomarkers that can detect metabolic dysfunction earlier and with greater precision than currently available tools. Lipoprotein particle size analysis represents a mature technology that is ready for broader clinical application, yet several barriers remain before it can be fully integrated into standard care. The primary obstacles are not technical but logistical: the need for standardization, cost reduction, and evidence from outcome-driven trials.
