The short answer
Measures Lp(a) — a genetically determined cardiovascular risk factor that standard lipid panels miss, measured from a standard blood draw. At TestWell it costs $34.99 plus a $6 lab processing fee, needs no fasting, and results post in 3–5 business days. Physician-authorized with no doctor's visit or insurance needed; draw at Quest or Labcorp.

Lipoprotein(a) is a type of LDL particle that is largely determined by genetics. Elevated Lp(a) is an independent risk factor for heart disease and stroke that standard lipid panels do not measure. Since Lp(a) levels are genetic and largely stable throughout life, this test only needs to be done once. The American Heart Association recommends measuring Lp(a) at least once for anyone with a family history of early heart disease.
Lipoprotein(a) is an LDL-like particle linked tightly to genetics. Elevated Lp(a) is an independent cardiovascular risk factor — measure once in a lifetime per ESC guidelines.
Anyone with family history of early heart disease, recurrent cardiovascular events despite well-controlled LDL, anyone doing a serious longevity / cardio workup. Measure once unless you start a PCSK9 inhibitor.

Your Lp(a) Hereditary Heart Risk Test results will include values for each of the 1 biomarker tested, along with reference ranges. Results are reviewed by a licensed physician before being released to your secure portal.
If any values fall outside the normal range, your report will include guidance on what that may mean and recommended next steps. You'll receive an email notification when your results are ready, typically within 3–5 business days.

Lab reports show where your value sits relative to established reference intervals—your physician interprets this in context for you. Already have results? Analyze them with your AI assistant against our physician-reviewed ranges.
No fasting required. No special preparation needed.
A Lp(a) Hereditary Heart Risk Test costs $34.99 at TestWell — $40.99 all-in when ordered alone, because the $6 lab processing fee is charged once per order, with no draw fee or physician fee added. Ordered directly from the labs' own consumer sites, the same test lists at $45.00 at Quest Health and $49.00 at Labcorp OnDemand (list prices checked Sep 12, 2026). Hospital outpatient labs typically bill around $150.00 self-pay for the same test, and often more. With insurance, what you pay depends on your deductible and your plan's negotiated rate; TestWell's price is fixed before the draw and is HSA/FSA-eligible. Full cost breakdown →

Lp(a) is an LDL particle with an extra protein (apo(a)) attached. Levels are 80-90% genetically determined and don't respond to diet or statins. Elevated Lp(a) raises heart attack and aortic stenosis risk independently of LDL — about 20% of the population is affected.
Below 30 mg/dL (or 75 nmol/L) is low risk. 30-50 mg/dL is moderate. Above 50 mg/dL is high cardiovascular risk. Above 75 mg/dL is very high — these patients warrant aggressive LDL lowering plus annual cardiac monitoring.
Lp(a) is 80-90% genetic and stable across decades. A single measurement gives you lifetime risk information. Repeat only if you start a PCSK9 inhibitor (which can lower Lp(a) by ~25%) or if methods change at your lab.
On TestWell, Lp(a) is $34.99. Quest Direct lists the same test at $55, walk-in hospital labs typically bill $120-150 without insurance.
No fasting required for Lp(a) alone. But it's almost always drawn alongside a Lipid Panel and ApoB, which do benefit from fasting.
Diet, exercise, and statins have minimal effect. Niacin lowers it modestly (~20%). PCSK9 inhibitors (Repatha, Praluent) lower it ~25%. New Lp(a)-targeted drugs (pelacarsen) are in late-stage trials and can lower levels 80%+. For now, the strategy is to aggressively lower other risk factors (LDL, ApoB, BP) when Lp(a) is high.
Ordered directly, a Lp(a) Hereditary Heart Risk Test lists at $45.00 at Quest Health (Quest Diagnostics' own site) and $49.00 at Labcorp OnDemand (prices checked September 2026).

Lp(a) Hereditary Heart Risk Test results are typically ready in 3–5 business days after your draw at Quest or Labcorp. TestWell emails you the moment they post, and your results dashboard shows each marker against its reference range with a plain-English explanation.
