Lp(a)
A genetically determined lipoprotein particle linked to cardiovascular risk that most cholesterol panels never test.
What is it
Lipoprotein(a) is a particle similar to LDL but with an additional protein called apolipoprotein(a). Its levels are largely set by genetics and remain relatively stable across a lifetime.
Despite being a well-studied cardiovascular risk marker, Lp(a) is not part of the standard cholesterol panel — most people have never had it measured.
Why it's measured
Elevated Lp(a) has been associated with increased cardiovascular risk in published research, independent of LDL cholesterol levels. Because it is genetically determined, knowing your Lp(a) once provides lasting information.
Reference range
Standard laboratory reference
< 30 mg/dL
Reference ranges vary by laboratory. Your individual reference range will appear on your test report and should be interpreted by your physician in the context of your overall health profile.
What results may indicate
Elevated
Has been associated with elevated cardiovascular risk in published research, even when standard cholesterol values appear normal.
Lower
Is generally considered favorable in research literature on cardiovascular risk.
These associations are general. They are not a personal diagnosis or prediction. Discuss your individual results with your physician in the context of your full health profile.
When it's measured
Lp(a) is most often tested once in adulthood, since values are largely determined by genetics. Discuss with your physician based on family history and personal risk profile.
