Quick highlights
- Practical estimate of atherogenic particle burden (ApoB)
- Useful when LDL-C is discordant with metabolic risk
- Often paired with ApoA1 for ApoB/ApoA1 ratio discussion
- Adds detail beyond standard lipid profile in selected cases
- Fasting depends on co-ordered triglycerides/lipids—follow instructions
- Lifestyle and medicines influence interpretation
- Supports monitoring response to lipid therapy
- Not a diagnosis; part of overall cardiovascular risk assessment
- Home blood collection available in many service areas
- SEO coverage: ApoB test, apolipoprotein B blood test, atherogenic particle test
What’s included

- Avoid alcohol 24 hours before test if possible
- Disclose statins and lipid medicines/supplements
- Stay normally hydrated
- Collect serum blood sample via trained phlebotomist

FAQs
Sometimes; fasting is commonly recommended when triglycerides/lipid profile is ordered together—follow instructions.
It reflects the number of atherogenic lipoprotein particles such as LDL and remnants.
They provide different information; ApoB can be useful when LDL-C does not match overall risk profile.
The ApoB/ApoA1 ratio may support clinician discussions about atherogenic vs protective particle balance.
Yes. Statins and other lipid therapies can change ApoB; disclose medicines.
No. It supports risk assessment and monitoring only.
Often same day or within 24 hours.
Serum blood sample.
Yes in many service areas.
Do not stop medicines unless your clinician instructs.
Lipid profile, HbA1c, blood pressure evaluation, and risk-factor review with clinician.

Yes; diet, exercise, weight management, and smoking cessation can improve lipid markers under clinician guidance.
In some people, particle number may still be elevated; ApoB can add clarity in selected cases.
Notes
Apo B reflects atherogenic risk and must be clinically interpreted.
