High-Sensitivity C-Reactive Protein: About This Test
What is it?
A high-sensitivity C-reactive protein (hs-CRP) test measures the amount of CRP (C-reactive protein) in your blood. This test may help find your risk of heart problems, especially when the results are considered along with other risk factors such as cholesterol, age, blood pressure, and smoking.
Why is this test done?
This test may be done to find out if you have an increased chance of having a sudden heart problem, such as a heart attack. But the connection between high CRP levels and heart attack risk is not understood very well.
A high level of CRP may mean a higher-than-normal risk of heart problems. If your risk for heart problems is high, your doctor may recommend lifestyles changes or medicine to help lower your risk.
Your doctor will discuss with you if you should have this test based on your general health and your health history.
How do you prepare for the test?
In general, there's nothing you have to do before this test, unless your doctor tells you to.
How is the test done?
A health professional uses a needle to take a blood sample, usually from the arm.
How long does the test take?

What happens after the test?
- You will probably be able to go home right away. It depends on the reason for the test.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to keep a list of the medicines you take. Ask your doctor when you can expect to have your test results.
