Educational information only. At Precursor, blood testing is requested and reviewed by a clinician and considered alongside your history and other markers, not as a stand-alone diagnosis. Testing is performed in NATA-accredited laboratories to ISO 15189 standards.
What is Lipoprotein(a)?
Lipoprotein(a), often written Lp(a), is an LDL-like particle with an extra protein attached. What makes it distinctive is that your level is largely set by your genes and stays relatively stable through life, changing little with diet or lifestyle. Many people with a raised level have no idea, because it is not part of a standard cholesterol test.
Why it matters
A high Lp(a) is an independent, inherited risk factor for cardiovascular disease and for narrowing of the aortic valve. Because it is genetic, a single measurement usually tells you your lifelong tendency, which is why it is often described as a once-in-a-lifetime test unless something changes clinically.
What your results can mean
If your result is higher
A raised Lp(a) adds to your overall cardiovascular risk on top of your other lipids. It cannot be lowered much by lifestyle, so it is used to inform how closely your other, modifiable risk factors should be managed.
If your result is within the reference range
A lower Lp(a) means this particular inherited risk factor is not adding to your cardiovascular risk, which is reassuring context alongside the rest of your lipid panel.
Australian reporting and interpretation
Lipoprotein(a) may be reported in nanomoles per litre (nmol/L) or mass units, depending on the assay. The RCPA reference interval is below 75 nmol/L. Results in different units should not be converted with a fixed factor, so use the units and reference interval printed on your own report.
Test your Lipoprotein(a) with Precursor
Because it is inherited and usually measured just once, Lp(a) is worth checking as part of a thorough baseline. At Precursor, lipid testing is requested and reviewed by a clinician within Full Advanced Bloods, a single draw covering your heart, metabolic, hormonal, kidney, liver, thyroid and nutrient markers together, with your clinician able to advise whether Lp(a) is relevant for you.
