Know Your Blood Parameter: Apolipoprotein B (ApoB)

1. Parameter Name 

   Apolipoprotein B (ApoB)

   
   

2. Test Type 

   Blood

   
   

3. Normal Range 

   • < 90 mg/dL (optimal for low-risk) 

   • < 70 mg/dL (for high cardiovascular risk)

     
     

4. High Levels Indicate 

   High levels of atherogenic particles (LDL, VLDL); strong predictor of heart disease.

   
   

5. Low Levels Indicate 

   Lower cardiovascular risk; may be seen with aggressive lipid-lowering therapy.

   
   

6. Why It's Tested 

   To estimate total number of atherogenic particles better than LDL-C.

   
   

7. Associated Symptoms (if abnormal) 

   No direct symptoms; increases silent cardiovascular risk.

   
   

8. What To Do If Abnormal 

   Modify diet, exercise, consider medications (e.g., statins or PCSK9 inhibitors).

   
   

9. Common Conditions Related 

   Atherosclerosis, familial hypercholesterolemia, insulin resistance

   
   

10. Nutrition or Lifestyle Connection 

    Reduce saturated fats, added sugars; focus on plant-based diet and physical activity.
