Worried about heart disease, even if your cholesterol levels are normal? Lipoprotein(a), or Lp(a), is a genetic risk factor for cardiovascular disease that standard cholesterol tests don’t detect. High Lp(a) levels can increase the risk of heart attacks and strokes, even in people with otherwise healthy lipid profiles. This test is ideal if you have a family history of heart disease or want a more detailed assessment of your cardiovascular risk.

Lipoprotein (a)
Learn more
Lipoprotein(a), or Lp(a), is a type of lipoprotein made by the liver. Lp(a) is very similar to LDL cholesterol but is more "sticky" as it also contains a protein called Apo(a). Lp(a) is thought to play an important role in the blood's clotting system, but raised levels are linked to a higher risk of cardiovascular disease, including heart attacks and strokes. Knowing your level can help stratify your risk. The amount of Lp(a) in your blood is determined by your genes and not affected by your age or sex.

FAQs
What do high lipoprotein A levels mean?
Lipoprotein(a) - also known as lp(a) - is a risk factor for heart disease, especially when LDL cholesterol is also raised. Lp(a) can accelerate the development of plaques forming in the arteries, which narrow and harden the arteries.
What affects lp(a)?
The concentration of lp(a) within the blood is genetically determined and will remain fairly constant in an individual over their lifetime.
What are lipoproteins?
Lipoproteins are made of fat (lipids) and proteins and transport cholesterol and triglycerides in your blood.
