Apolipoprotein B

Apolipoprotein B (APO B) Test - This test measures the level of Apolipoprotein B (APO B) in your blood, which is a strong indicator of coronary artery disease (CAD). It's particularly useful because APO B levels can be elevated even when LDL cholesterol levels are normal, helping to identify risk in patients who might otherwise be considered low-risk based on cholesterol alone.
