Lipoprotein a (Lp(a)) is a type of lipoprotein particle made up of an apolipoprotein (ApoB) and an apolipoprotein (ApoA) attached to a molecule of cholesterol. It is often measured through a blood test to help diagnose cardiovascular disease, stroke, and other health conditions.
What is Lp(a) and What Does it Do?
Lp(a) is a lipoprotein particle that is made up of an ApoB protein and an ApoA protein attached to a molecule of cholesterol. This particle is very similar to LDL (low-density lipoprotein) cholesterol and is considered an independent risk factor for cardiovascular disease. Lp(a) is also known as lipoprotein(a), and it is produced in the liver and found in the bloodstream.
Why is Lp(a) Tested?
Lp(a) is tested to help diagnose cardiovascular disease, stroke, and other health conditions. High levels of Lp(a) have been linked to an increased risk of developing cardiovascular disease and stroke, as well as other health issues. The test can also help to identify any genetic factors that may be contributing to high levels of Lp(a).
What Do The Results Mean?
The results of an Lp(a) test indicate whether a person’s levels are higher or lower than average. High levels of Lp(a) (above 30mg/dL) indicate an increased risk of cardiovascular disease and stroke. However, low levels of Lp(a) (below 10mg/dL) are associated with a reduced risk of cardiovascular disease and stroke.
Who Should Get an Lp(a) Test?
Your doctor may recommend that you get an Lp(a) test if you have a family history of cardiovascular disease, stroke, or other health conditions. Your doctor may also recommend an Lp(a) test if you are at risk for developing cardiovascular disease due to factors such as smoking, high blood pressure, obesity, or a sedentary lifestyle. Additionally, if you have experienced any recent symptoms associated with cardiovascular disease, such as chest pain or shortness of breath, your doctor may recommend an Lp(a) test.
