Get an advanced lipid analysis in Delhi - the Apolipoprotein B/A1 test measures ApoB and ApoA1 and calculates their ratio to provide a more accurate assessment of cardiovascular risk than a standard lipid profile.
The Apolipoprotein B/A1 Profile measures two blood proteins — ApoB (present on atherogenic particles such as LDL and VLDL) and ApoA1 (the major protein on protective HDL particles). The ApoB/ApoA1 ratio helps identify imbalance between 'bad' and 'good' lipoproteins and is a strong indicator of cardiovascular risk.
No special preparation is required for the Apolipoproteins B/A1 Profile or Ratio test. It does not require fasting, so you can take the test at any time of the day. However, it is always recommended to inform your doctor about any ongoing medications, supplements, or existing medical conditions, as these may influence the test results. This helps ensure accurate interpretation and reliable assessment of your heart health.
A simple blood draw (venous sample) is taken by a trained phlebotomist. At Redcliffe Labs Delhi, you can choose home sample collection or a lab visit. Reports are typically available within 13 hours depending on lab processing.
Interpretation varies by lab and patient profile. Typical guidance:
| Range (ApoB/ApoA1) | Interpretation |
|---|---|
| Low (e.g. < 0.6–0.7) | Lower cardiovascular risk |
| Moderate (e.g. ~0.7–0.9) | Moderate risk — monitor & modify lifestyle |
| High (> 0.9) | Higher risk — further evaluation advised |
Note: Exact numeric cutoffs may differ by lab; always review results with your physician.
