Cholesterol and Heart Risk Panel in Arizona

What this test measures

Cholesterol is a waxy substance the body uses to build cells and hormones, and it travels through the blood packaged in lipoproteins. Low-density lipoprotein carries cholesterol to tissues and is often called the bad cholesterol, while high-density lipoprotein helps return cholesterol to the liver. Triglycerides are another type of fat measured in the same standard lipid panel.

The test uses a blood sample, usually drawn from a vein. A standard lipid panel reports total cholesterol, HDL, LDL, and triglycerides. Some cardiac-focused orders add apolipoprotein B, lipoprotein(a), high-sensitivity C-reactive protein, or a ratio such as total cholesterol to HDL. Calculated values depend on the measured components and the laboratory's formula.

Results are interpreted alongside age, blood pressure, smoking status, diabetes, and family history, not in isolation. A single reading describes one point in time, and values can shift with diet, weight, activity, illness, and medications. Clinicians use the panel to estimate risk and to decide whether lifestyle changes or further evaluation are appropriate.
