C-Reactive Protein Test, High Sensitivity
Below is a plain-language overview of the c-reactive protein test, high sensitivity. This high sensitivity blood test measures C-Reactive Protein (CRP) to help assess inflammation and potential risk for heart disease.
What this test is
C-Reactive Protein (CRP) is a substance produced by the liver in response to inflammation anywhere in the body. A high sensitivity CRP test (hs-CRP) is a more precise measurement used to evaluate long-term risk of cardiovascular events.
What it measures
- C-Reactive Protein (CRP), High Sensitivity — reflects inflammation and cardiovascular risk
What the test involves
This test requires a blood sample, which is typically collected through a standard venipuncture procedure at a laboratory or clinic.
Why it is often ordered
Clinicians often order this test to assess a person's risk of developing heart disease or experiencing a heart attack or stroke. It can also be used to monitor the effectiveness of treatments aimed at reducing cardiovascular risk.
Preparation
Follow the specific preparation instructions provided by the laboratory where you will have your blood drawn. Some labs may require you to fast before the test.
How results are reported
Results are typically reported within a few business days. Reference ranges, which indicate what is considered typical, vary between laboratories.
Before you go
- Fasting requirements
- Test preparation instructions
- Typical turnaround time
FAQ
Frequently asked questions
What does a high hs-CRP result mean?
A high result suggests increased inflammation in the body, which may indicate a higher risk for heart disease. It is important to discuss your results with your healthcare provider for proper interpretation.
Can hs-CRP detect current heart attack?
This test is primarily used for assessing long-term risk, not for diagnosing an acute event like a current heart attack. Other tests are used for that purpose.
How is hs-CRP different from a regular CRP test?
The high sensitivity version (hs-CRP) can detect lower levels of CRP than a standard CRP test, making it more useful for assessing long-term cardiovascular risk.
What factors can affect hs-CRP levels?
Levels can be influenced by various factors including infections, injuries, autoimmune conditions, and even normal bodily processes like menstruation. Your clinician will consider these when interpreting your results.
