Good to knowOne result rarely tells the whole story. Your provider looks at your results together with your symptoms, exam, and other tests.
What the test is
It's different from the standard CRP test used for infection and inflammation. It's not used if you're sick, since infection raises it.
Why it's done
- Helping decide on heart prevention treatment when your risk is in the middle range
Getting ready and what happens
- No fasting is needed. Avoid testing during a cold or other illness.
How the test is done
- A health worker cleans the skin, puts a band around your arm, and draws blood from a vein with a small needle. It takes a few minutes.
What the results mean
| Result | Typical range for adults |
|---|---|
| Lower risk | Below 1.0 mg/L |
| Average risk | 1.0 to 3.0 mg/L |
| Higher risk | Above 3.0 mg/L |
| Likely another cause | Above 10 mg/L (repeat after illness) |
Normal ranges vary from lab to lab and can differ by age, sex, and pregnancy. Your report lists your lab's own range next to each result. A result a little outside the range is often not a problem.
Higher result
May tip the decision toward a statin or other prevention steps.
Questions to ask your provider
- What do my results mean for me?
- Do I need to repeat this test or have other tests?
- Will this change my treatment?
- Should I repeat it when I'm not sick?
Risks
A blood draw is very safe. You may have slight pain or a small bruise where the needle went in.
