The APOB/A1 ratio is considered by some researchers and healthcare professionals as a more accurate indicator of cardiovascular risk compared to traditional cholesterol measurements, such as LDL cholesterol or total cholesterol. An elevated APOB/A1 ratio may suggest an imbalance between atherogenic (artery-clogging) and anti-atherogenic (artery-protective) lipoproteins, which could indicate an increased risk of developing cardiovascular disease.
By measuring the APOB/A1 ratio, healthcare professionals may gain additional insights into a person's cardiovascular risk profile, potentially helping in the assessment and management of cardiovascular disease.
What we test
Apolipoprotein Ratio
The apo B/apo A1 ratio indicates the cholesterol balance between potentially atherogenic (bad) and anti-atherogenic (good) particles.
Apo A is a protein carried in HDL ("good") cholesterol. It helps start the process for HDL to remove bad types of cholesterol from your body. In this way, apolipoprotein A can help to lower your risk for cardiovascular disease.
Apo B containing lipoproteins are the ones most likely to enter the wall of the arteries. They are capable of trafficking cholesterol into the artery wall, and if present in increased numbers may be the main initiating factor in atherosclerosis.
The apo B/apo A-I ratio indicates the cholesterol balance between potentially atherogenic (bad) and antiatherogenic (good) particles. The ratio is strongly related to risk of cardiovascular disease.
