Detailed Clinical Overview
Apolipoprotein B (ApoB) is the primary structural protein found on all atherogenic lipoprotein particles, including LDL, VLDL, IDL, and Lp(a).
Because each atherogenic particle carries exactly one molecule of ApoB, measuring ApoB provides a direct particle count — a more accurate predictor of cardiovascular event risk than LDL cholesterol, especially in patients with diabetes, obesity, metabolic syndrome, or elevated triglycerides.
Conducted inside QXL Diagnostics' NABL Accredited central super speciality laboratory (MC-6849) using automated immunoturbidimetric analyzers calibrated to international WHO-IFCC standards.
Blood specimens are collected using single-use SST vacuum collection tubes by trained phlebotomists and transported under cold-chain conditions.
Every result undergoes automated dual-level internal quality control (IQC) and medical sign-off by Dr. Shantakumar Muruda, MD (Clinical Biochemistry), NABL Lead Assessor.
Diagnostic Limitations & Interferences
- Marked lipemia or gross hemolysis may interfere with optical turbidimetric measurement.
- Results must be correlated with overall clinical risk profile by treating physician.

Reference Ranges — Apolipoprotein B (ApoB) Test in Bangalore
NABL-validated intervals · Adults · values may vary by age & sex
| Parameter / Group | Range | Unit | Status |
|---|---|---|---|
| Desirable (Low to Moderate ASCVD Risk)Standard primary prevention target for adults without major cardiovascular risk factors | < 90 | mg/dL | Normal |
| High Risk TargetRecommended target for patients with diabetes, metabolic syndrome, or marked dyslipidemia | < 80 | mg/dL | Borderline |
| Very High Risk TargetStrict secondary prevention target for established coronary artery disease or acute coronary syndrome | < 65 | mg/dL | Abnormal |
⚕️ Reference ranges are population-based guidelines. Results must be interpreted in clinical context by a qualified physician. Always consult your doctor before making healthcare decisions.
Frequently Asked Questions
Q: What is the Apolipoprotein B (ApoB) test?
A: The Apolipoprotein B (ApoB) test counts the total number of circulating atherogenic particles (LDL, VLDL, IDL, Lp(a)) in your blood. Unlike standard cholesterol tests that measure particle weight, ApoB counts the actual particles that cause arterial plaque.
Q: Why is ApoB a better cardiac risk marker than LDL cholesterol?
A: Atherosclerosis is driven by the number of particles penetrating the arterial wall. In people with insulin resistance, diabetes, or high triglycerides, LDL particles are small and dense, meaning LDL cholesterol mass can appear normal even when the particle number (ApoB) is dangerously elevated.
Q: What fasting or preparation is required for ApoB?
A: No fasting is required for an isolated ApoB test because particle counts do not vary significantly after meals. However, if your doctor has co-ordered Fasting Blood Sugar or a full Lipid Profile, observe an 8 to 10 hour overnight fast.
Q: How is the sample collected for ApoB?
A: A certified QXL phlebotomist collects 2 mL of venous blood in a sterile gold-top SST tube and transports it in a temperature-controlled cold box to our NABL laboratory.
Q: What is the normal reference range for ApoB?
A: Desirable level is below 90 mg/dL for individuals at low to moderate cardiovascular risk. For high-risk individuals (such as those with diabetes), the target is below 80 mg/dL, and for very high-risk patients with known heart disease, the guideline target is below 65 mg/dL.
Q: How fast will I get my official report for ApoB?
A: Verified digital PDF reports for ApoB are delivered within 12 Hours of sample collection via WhatsApp and Email.
Q: Can I book home sample collection for ApoB in Bangalore?
A: Yes! QXL Diagnostics provides free doorstep sample collection across all Bengaluru localities including Kengeri, RR Nagar, Yelahanka, Whitefield, Koramangala, and HSR Layout.
Q: What factors or medications can interfere with ApoB results?
A: Lipid-lowering therapies (statins, PCSK9 inhibitors, ezetimibe) significantly lower ApoB levels. Acute inflammatory illness, severe liver dysfunction, and pregnancy may also alter circulating apolipoprotein levels.
