Cardio IQ® Lipoprotein Fractionation, Ion Mobility
Also known as: CardioIQ®, HDL Subfractions, Cardio IQ®, IDL Subfractions, Cardio IQ®
Use
Ion Mobility lipoprotein fractionation separates unmodified lipoproteins by size, allowing high‑resolution quantification of lipoprotein particle subclasses. It provides direct measurement of small, medium, and total LDL particle numbers, LDL peak size, LDL pattern, and large HDL particle number — metrics correlated with cardiovascular disease risk and not captured by conventional lipid panels. It aids in CVD risk assessment and monitoring therapeutic response in patients with intermediate or high risk based on traditional risk factors.
