Lipoprotein Particles and Apolipoproteins
Lipoproteins are substances made of protein and fat that carry cholesterol through your bloodstream.
Apolipoprotein A-1Optimal range: 102 - 200 mg/dL
Apolipoprotein 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. Apolipoprotein A levels can be measured. But it's more common to measure the HDL and LDL ("bad") cholesterol when looking at cardiovascular risk.
This biomarker is useful for:
- Evaluating risk for atherosclerotic cardiovascular disease
- Aiding in the detection of Tangier diseaseLEARN MORE
Apoprotein B100 (ApoB 100)Optimal range: 0 - 80 mg/dL
Apolipoprotein B100 (apoB100) is a building block of very low-density lipoproteins (VLDLs), intermediate-density lipoproteins (IDLs), and low-density lipoproteins (LDLs). These related molecules all transport fats and cholesterol in the bloodstream.LEARN MORE
LDL SizeOptimal range: 20.5 - 100 nm
Small LDL-P and LDL Size are associated with CVD risk, but not after LDL-P is taken into account.LEARN MORE
LDL-POptimal range: 0 - 1000 nmol/L
Lipoproteins are particles that transport fats throughout the body. These particles are essential and carry a combination of proteins, vitamins, cholesterol, triglyceride, and phospholipid molecules.
The composition of a lipoprotein particle changes as it circulates in the blood. Some molecules are removed and others are added, resulting in lipoprotein particles with variable amounts of cholesterol. Low-density lipoprotein particles (LDL-P) are bi-products of fat transport that remain in circulation for an extended time. While in circulation, LDL-P can penetrate the artery wall and get stuck, forming a fatty plaque. These plaques can build over time and lead to blockages, resulting in heart attacks and strokes.LEARN MORE
Lipoprotein(a) / Lp(a)Optimal range: 0 - 30 mg/dL
Lipoprotein(a) is a unique lipoprotein that has emerged as an independent risk factor for developing vascular disease.LEARN MORE
LP-IR ScoreOptimal range: 0 - 45 Units
The LP-IR score assesses an individual’s insulin resistance level and diabetes risk.LEARN MORE
Small LDL-POptimal range: 0 - 527 nmol/L
These particles are associated with an increased risk of heart disease; more of these small particles lead to greater risk. Your Small LDL particle score can vary widely, with a lower score being much better.LEARN MORE
