Description
Why It’s Done:
The ApoB test is used to:
• Assess the risk of cardiovascular disease (heart attack, stroke, atherosclerosis)
• Evaluate lipid disorders, especially when LDL-C and non-HDL-C levels are borderline or misleading
• Guide and monitor lipid-lowering therapy (such as statins)
• Help identify patients with familial hypercholesterolemia or metabolic syndrome
Doctors may order this test if you:
• Have a family history of early heart disease
• Have diabetes, obesity, or high triglycerides
• Are on treatment for high cholesterol and need detailed risk assessment
Preparation:
• Fasting is usually not required for this test, but some doctors may recommend fasting for 8–12 hours if it’s done along with a complete lipid panel.
• A blood sample is taken from a vein.
• Inform your healthcare provider about:
o Any medications or supplements you are taking
o Personal or family history of heart disease, diabetes, or lipid disorders
