This test measures ApoB, the main protein found in LDL and other atherogenic lipoproteins.
Diagnostic Value: Elevated ApoB correlates closely with the number of particles that promote plaque formation and heart disease.
Clinical Significance: More accurate than LDL cholesterol alone, ApoB is a key marker for assessing atherosclerosis risk.
Symptom Correlation: Typically asymptomatic until advanced cardiovascular disease develops.
The ApoB test helps pinpoint atherogenic risk and guide lipid-lowering therapy.
