Why Standard Cholesterol Tests Don't Tell the Full Story — Especially in Mississippi

Mississippi has some of the highest rates of heart disease in the United States. Yet the standard lipid panel — total cholesterol, LDL, HDL, and triglycerides — that most patients receive at an annual physical gives an incomplete picture of cardiovascular risk. Many people who have heart attacks have "normal" cholesterol.

Not All LDL Is the Same

The problem is that not all LDL cholesterol is the same. Standard LDL is a calculated estimate of the total amount of LDL in your blood. But research increasingly shows that particle size and number matter more than total LDL. Small, dense LDL particles are significantly more atherogenic — more likely to embed in arterial walls and drive plaque formation — than large, buoyant particles. You can have the same total LDL as two different people and carry very different actual risk.

What the CardioIQ Panel Measures

The CardioIQ Advanced Lipid Panel, which Julep Health offers, goes deeper. It measures:

• LDL particle number and size
• Lp(a) — a genetically determined lipoprotein that standard panels don't test and that carries independent cardiovascular risk
• Apolipoprotein B
• Triglyceride and HDL subfractionation
• High-sensitivity CRP — an inflammatory marker that reflects arterial inflammation, now understood to be a core driver of cardiovascular disease

Why This Matters in Mississippi

Given Mississippi's cardiovascular disease burden, this level of detail is clinically meaningful. It's the difference between knowing your cholesterol number and actually understanding your risk — and being able to do something about it before an event occurs.
