Compares the amount of total cholesterol in your blood to the amount of high-density lipoprotein (HDL) cholesterol. Elevated ratios may indicate low levels of good cholesterol. Useful in identifying people who may be at risk even if their total cholesterol appears “normal.”

Known as "good" cholesterol, HDL actively removes cholesterol from the artery walls and transports it to the liver for disposal. Higher levels are generally protective against heart disease, while low levels are associated with increased cardiovascular risk.

LDL carries cholesterol to the arteries and, when elevated, may contribute to plaque buildup and increase the risk of heart disease.

Represents all atherogenic (potentially harmful) cholesterol particles; used to assess cardiovascular risk.

The total amount of cholesterol in the blood, including HDL, LDL, and other lipid components.

A form of fat stored in the blood; elevated levels are associated with increased cardiovascular risk and metabolic disorders.

The main protein component of HDL "good" cholesterol. Higher levels are generally associated with a lower risk of cardiovascular disease, as ApoA helps transport cholesterol away from the arteries and back to the liver. Low levels may suggest reduced protective cholesterol function and can be associated with increased cardiovascular risk.

Found in LDL (“bad”) cholesterol; a better predictor of heart disease risk than LDL alone.

Compares bad to good cholesterol; a strong indicator of cardiovascular risk.
