Alternate Names : CRP, High-sensitivity C-reactive protein, hs-CRP
Normal CRP values vary from lab to lab. Generally, there is no CRP detectable in the blood.
Your doctor may also use a highly sensitive test called hs-CRP to help determine your risk of heart disease. According to the American Heart Association:
- You are at low risk of developing cardiovascular disease if your hs-CRP level is lower than 1.0mg/L
- You are at average risk of developing cardiovascular disease if your levels are between 1.0 and 3.0 mg/L
- You are at high risk for cardiovascular disease if your hs-CRP level is higher than 3.0 mg/L
Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
