# What does a high Lipoprotein(a) mean?

> Lipoprotein(a) is inherited and mostly fixed for life; about 1 in 5 people has a high level. Above about 125 nmol/L (or 50 mg/dL) is considered high and independently raises the risk of heart attack, stroke and aortic valve stenosis. It doesn't respond to diet or statins, so a high result changes how aggressively LDL, blood pressure and other risks are treated — and prompts testing first-degree relatives.


## What is the normal range for Lipoprotein(a)?

- age 18+: 0.000 – 75.0 nmol/L

Above 75 nmol/L is associated with increased cardiovascular risk. Lp(a) is largely genetic and stable over time.

## What are the common causes of high Lipoprotein(a)?

1. Genetics (the LPA gene) — the dominant determinant
2. Kidney disease (nephrotic syndrome) and hypothyroidism modestly raise it
3. Menopause modestly raises it

## What symptoms go with high Lipoprotein(a)?

- None — risk is silent

## What do clinicians usually check next?

- No repeat needed; it's a once-in-a-lifetime test unless conditions change
- Lower LDL/ApoB more aggressively with the clinician
- Screen parents, siblings and children
- Consider coronary calcium scoring for risk refinement

Follow-up tests at TestWell: [Calcium](https://www.test-well.com/tests/calcium) ($26.99).

## How do you recheck Lipoprotein(a)?

| Test or panel | Type | Price | Fasting | Results |
| --- | --- | --- | --- | --- |
| [Advanced Lipid Panel](https://www.test-well.com/tests/advanced-lipid-panel) | Test | $90.99 | Yes | 3–5 business days |

Plus one $6 lab processing fee per order; physician authorization included.

## Common questions

### Can I lower lipoprotein(a)?

Not meaningfully with lifestyle or statins. PCSK9 inhibitors lower it 20–30%; dedicated Lp(a)-lowering drugs are in late-stage trials. Meanwhile the strategy is to drive every other risk factor down.

### Should my family be tested?

Yes — it's inherited, so first-degree relatives have a substantial chance of also being high.
