About Our C-Reactive Protein (CRP) Test

The C-Reactive Protein (CRP) test measures levels of CRP, a protein produced by the liver in response to inflammation, infection, or tissue injury. CRP levels rise rapidly, often within hours, making this test a sensitive marker for detecting active inflammation in the body.

Although CRP does not identify the specific cause of inflammation, elevated levels can signal acute injury, bacterial infection, autoimmune activity, or post-surgical complications. This test is commonly used in clinical settings to assess inflammatory status and monitor how conditions respond to treatment.

What Is Included In This Test?

This test measures standard CRP levels in your blood to evaluate the presence and severity of inflammation.

Your results can help:

Detect active inflammation or infection
Monitor response to antibiotics or anti-inflammatory treatment
Assess inflammatory complications after surgery
Support evaluation of autoimmune or inflammatory conditions
Identify inflammation related to acute medical events

This standard CRP test is designed to detect moderate to severe inflammation. For assessing low-level inflammation associated with cardiovascular risk, a high-sensitivity CRP (hs-CRP) test is recommended instead.

Who Should Consider This Test?

This test is ideal for individuals who need evaluation or monitoring of inflammation related to illness, injury, or medical treatment.

You should consider this test if you:

Have symptoms of infection or inflammation
Are recovering from surgery and need complication monitoring
Have an inflammatory or autoimmune condition
Are being evaluated for acute medical conditions such as sepsis or myocardial injury
Need ongoing monitoring of inflammatory disease activity

Timely detection of inflammation can support faster diagnosis, treatment decisions, and recovery.

Common Questions:

Is this the same as a cardiac CRP test?

No, this standard CRP test detects moderate to severe inflammation. A high-sensitivity CRP (hs-CRP) test is used to assess cardiovascular risk.

Why is CRP testing important?

CRP testing helps identify inflammation early, monitor disease activity, and guide timely treatment decisions.
