About the test
Apolipoprotein B (apoB) is another important biomarker related to lipoproteins, but unlike apolipoprotein A1 (apoA1), it is associated with low-density lipoprotein (LDL) particles, commonly known as "bad cholesterol." LDL particles transport cholesterol from the liver to peripheral tissues, and elevated levels of LDL cholesterol in the blood are considered a significant risk factor for atherosclerosis and cardiovascular disease.
Apolipoprotein B is the primary structural protein of LDL particles, constituting about 90% of their protein content. Each LDL particle typically contains one molecule of apoB. The measurement of apoB levels in the blood can provide valuable information about the number of LDL particles present, as every LDL particle contains one apoB molecule.
LDL cholesterol is known to contribute to the formation of atherosclerotic plaques in the arteries, leading to narrowing and hardening of the blood vessels. Therefore, measuring apoB levels can help in assessing the total number of atherogenic LDL particles and their potential impact on cardiovascular health.
Compared to LDL cholesterol alone, apoB is considered a more accurate measure of atherogenic particles because it reflects the number of LDL particles rather than just their cholesterol content. Some individuals may have a high number of small, dense LDL particles, which are more atherogenic, while others may have a predominance of larger, less harmful LDL particles. ApoB provides a better estimation of the overall atherogenic burden in such cases.
High levels of apoB are associated with an increased risk of developing cardiovascular diseases, such as heart attacks and strokes. Therefore, measuring apoB, along with other lipid markers like LDL cholesterol and triglycerides, helps in evaluating an individual's cardiovascular risk more comprehensively.
It's worth noting that while apoV is an important biomarker, it is just one part of the larger lipid profile and should be considered in the context of an individual's overall health and risk factors for cardiovascular disease. Regular monitoring of lipid levels, including apoB, can help in the early detection and management of cardiovascular risk. The Cholesterol Blood Test is our most popular panel to have on subscription.

Need more biomarkers? Check out our Cholesterol Blood Test. You can add ApoA1 and ApoB to the cholesterol panel for a complete picture.
Most of the biomarkers we offer in the "ready made" panels are also available separately. So if your favourite test panel is missing a biomarker you would like to have, no problem, you can add whatever you need to one of our standard panels using the "Pick-n-mix" options, such as this one.
