The LDL/non-HDL ratio shows how much of your atherogenic (artery-damaging) cholesterol is carried specifically by LDL versus triglyceride-rich particles like VLDL. Non-HDL includes LDL plus those triglyceride-rich remnants, so a ratio close to 1 means LDL accounts for nearly all of your harmful cholesterol, while a lower ratio means triglyceride-rich particles are contributing a larger share. It helps clarify which type of particle is driving risk, which can point toward different lifestyle priorities.
LDL/Non-HDL isn't sold on its own. It comes in a standard lipid panel, about $45. A fuller workup adds Vitamin D ($75), hs-CRP ($69), ApoB ($50), and ApoA1 ($50). You can test LDL/Non-HDL and 100 other biomarkers for $190 as part of an Empirical membership.
Empirical is FSA/HSA eligible, so you can pay with pre-tax dollars. Fast for 8-12 hours beforehand for the most accurate lipid and metabolic results, and expect results in days rather than weeks.
LDL/Non-HDL is drawn at 2,200+ Quest and BioReference patient service centers across the US, so there's usually one within a short drive. Browse the full directory to find the one closest to you.
