A simple blood test for lipoprotein(a), or LP(a), could help identify a major hidden risk for heart attacks and strokes. However, many people remain unaware of it, and routine screenings are not yet widespread.

Understanding LP(a)

LP(a) is an inherited cholesterol particle that can increase plaque buildup and the risk of heart attacks and strokes. According to Dr. Indu Poornima, director of clinical cardiology and imaging and preventive cardiology at Allegheny Health Network, LP(a) is both atherogenic and thrombogenic, which are the two components that lead to a heart attack or stroke.

LP(a) is not included in standard cholesterol panels, which contributes to the lack of awareness. Approximately 20 to 25% of people are believed to have elevated LP(a), which is almost entirely inherited and remains relatively stable throughout a person’s life.

Insurance Coverage and Testing

Insurance coverage for the test varies. The trade group representing America’s health insurance plans, AHIP, stated that it is the determination of each individual plan to cover this test and under which circumstances. UnitedHealthcare said its policy is under review, while Aetna has updated its policy to cover LP(a) screening in line with the new guidelines.

For those without insurance coverage, Labcorp and Quest Diagnostics offer the test for about $50 without a prescription. Quest Diagnostics reported increased demand for the test since the guidelines changed, noting that close to 30% of people tested have abnormal LP(a) levels.

Doctors emphasize that controlling LDL cholesterol and other risk factors can reduce the impact of elevated LP(a). If you control those other risk factors really well, including keeping your LDL levels below 70, sometimes ideally below 55, the likelihood that the LP(a) is going to have an impact is definitely lowered, according to Dr. Poornima.
