Lipoprotein(a) [Lp(a)] test
Lp(a) is an inherited cholesterol particle that raises heart and stroke risk.

- Reveals a genetic risk that diet and exercise don't change much.
- Usually needs testing only once, since levels stay stable for life.
- Explains early heart disease in families with "normal" cholesterol.
- Helps your physician decide how aggressively to manage other risks.
- Rarely included in a standard physical.
What is Lp(a)?
Lp(a) is an LDL-like particle with an extra protein attached, called apolipoprotein(a). Your level is set mostly by your genes, and about one in five people has an elevated level.
Why Lp(a) matters
Lp(a) promotes both plaque and clotting. High levels raise the risk of heart attack, stroke and aortic valve narrowing, often at younger ages.
What your Lp(a) results mean
- Low or in range: your inherited risk from Lp(a) is low. There's usually no need to retest.
- High: your baseline heart risk is higher. Your physician may focus harder on ApoB, blood pressure and blood sugar.
- Context matters: results come in nmol/L or mg/dL, and the two units can't be converted exactly.
Standard vs. optimal range
| Range | |
|---|---|
| Standard lab range | Below 75 nmol/L (about 30 mg/dL); 125 nmol/L (about 50 mg/dL) or more is considered high risk |
| Insyght optimal range | Set by the Insyght medical team |
Do I need an Lp(a) test?
Did a parent or sibling have a heart attack or stroke young? Is your cholesterol "fine" but your family history isn't? Most major heart guidelines now suggest testing Lp(a) at least once.
Test the risk you inherited
Insyght includes Lp(a) in every panel, along with ApoB and full lipids, reviewed by a physician. $199 a year.
