Abstract | BACKGROUND: OBJECTIVE: The aim of the study was to compare RLP-C levels estimated from basic lipid parameters to those measured by ultracentrifugation. METHODS: RESULTS: Our cohort was 48% male, and median (interquartile range) age was 59 (49-69) years. Median (interquartile range) RLP-Cestimated and RLP-Cmeasured were 23 (16.4-33.2) and 24 (19-32) mg/dL, respectively. The correlation between RLP-Cestimated and RLP-Cmeasured was 0.76. Based on the specified definition of RLP-Cestimated, the correlation between RLP-Cestimated and triglyceride/5 for triglyceride < 355 mg/dL was exactly 1.0. RLP-Cestimated was lower than RLP-Cmeasured in the first and second quintiles of RLP-Cestimated but greater in the highest quintile. The correlations with RLP-Cestimated-N were 0.98 and 0.81 for RLP-Cestimated and RLP-Cmeasured, respectively. CONCLUSIONS: A previously used estimate of RLP-C using basic lipid parameters correlates weakly with remnants measured by ultracentrifugation. Our findings emphasize the need to standardize definitions and measurements of RLP-C.
