Lipoprotein (a)

Lipoprotein A (Lp-A) is a type of lipoprotein that transports cholesterol in the blood to cells throughout the body. Lp-A is classified as an LDL-like (low-density lipoprotein) molecule that is bound to a molecule of apolipoprotein (a). The values of Lp-A do not appear to be regulated by the same mechanisms as LDL-cholesterol like diet or lifestyle. Instead, it is more affected by hereditary factors. Nevertheless, high levels in individuals at risk can be useful in alerting them to the need to eliminate or control other high-risk factors or monitor lipid-lowering treatments. A Lipoprotein (a) test may be recommended if you have an existing heart disease, have recently had a heart attack or stroke, or if your LDL cholesterol levels are elevated. 

The goal of screening you for Lp-A is early detection of potential cardiovascular problems. Many people do not show any symptoms of high Lp-A. Lp-A levels are largely driven by genes that can be passed down through families. This means you could have a high Lp-A even if you have a healthy lifestyle. So, your doctor may ask to perform the Lipoprotein (a) test, especially if you have a family history of cardiovascular diseases or if you are at risk of developing heart ailments. The Lipoprotein (a) test may also be used to monitor ongoing treatment for cholesterol reduction or if the desired cholesterol levels are not being attained during an ongoing high cholesterol treatment.

No special preparation is needed before undergoing the Lipoprotein (a) test. Test result ranges are approximate and may differ slightly between labs depending on the methodology and laboratory guidelines. Talk to your doctor about your specific test results. The test results can guide your doctor to tailor a personalized treatment plan to reduce the risk of potential cardiovascular disease and improve your overall health.
