Non-Malaysian citizens are subject to 6% SST, to be verified and paid at the counter before screening.
Apolipoprotein B (ApoB) is the primary structural protein of low-density lipoprotein (LDL) and very-low-density lipoprotein (VLDL). Since each atherogenic lipoprotein particle (LDL, VLDL, IDL, etc.) contains one ApoB, ApoB levels provide a direct measure of the number of atherogenic particles.
Elevated ApoB indicates a higher concentration of harmful lipoproteins, strongly linked with atherosclerosis, coronary heart disease, and stroke.
A venous blood sample is taken to measure ApoB. Interpretation should be combined with lipid profile, lifestyle, family history, and clinical context.
Q1: What is the difference between ApoB and LDL-C?
A: LDL-C measures cholesterol concentration, while ApoB reflects the number of harmful particles more accurately.
Q2: Does high ApoB always mean atherosclerosis?
A: Not necessarily, but it indicates higher risk and should be evaluated with other lipids and clinical findings.
Q3: How often should ApoB be tested?
A: High-risk individuals are advised to test annually, or as recommended by a physician.
