Is the Lp(a) test worth it? Cost and the "once in a lifetime" guidance

Whether a test is worth it depends on why it is being ordered, which is a question for you and a clinician. What we can show is what the Lp(a) test costs, what it is backed by, and what it does not tell you (prices checked Oct 23, 2026).

What the evidence says

The 2019 ESC/EAS guideline states that Lp(a) measurement should be considered at least once in each adult's lifetime to identify very high inherited levels (>180 mg/dL, >430 nmol/L) (Class IIa, Level C). A 2024 National Lipid Association focused update found sufficient evidence to support measuring Lp(a) at least once in every adult for risk stratification. The 2018 AHA/ACC guideline lists Lp(a) ≥50 mg/dL or ≥125 nmol/L as a risk-enhancing factor in selected individuals. Assay standardization differs between laboratories, and mg/dL and nmol/L results are not directly interchangeable.

What guidelines, insurers and the lab say

• ESC/EAS dyslipidaemia guideline (2019): "Lp(a) measurement should be considered at least once in each adult person’s lifetime to identify those with very high inherited Lp(a) levels".
• European Atherosclerosis Society (2022): "Lp(a) should be measured at least once in adults to identify those with high cardiovascular risk." It notes that "Lp(a) concentration is predominantly determined by genetics (>90%)".
• National Lipid Association (2024): "We now have sufficient evidence to support the recommendation to measure Lp(a) levels at least once in every adult for risk stratification."
• 2026 ACC/AHA dyslipidemia guideline (as summarized in a 2026 review): "Measurement of Lp(a) at least once in adulthood is among the most clinically relevant changes."
• One insurer's policy (Aetna CPB 0381): covers a "One-time lipoprotein(a) [Lp(a)] test for all adults aged 19 years and older to assess ASCVD risk", and says "Repeat Lp(a) testing is considered not medically necessary because Lp(a) levels are largely determined by genetics and remain relatively stable over a person’s lifetime".

What it does not tell you

• Units differ between labs: the EAS says "This panel does not recommend using a standard factor to convert between mg/dL and nmol/L, as assays vary extensively." Compare results only in the same unit.
• A result describes inherited risk; the statements above do not say what to do about a result, which is a question for a clinician.

This page does not say whether anyone should take the test. Insurance and HSA/FSA rules are covered in insurance and HSA for lab tests.
