C-Reactive Protein (CRP) by Turbidimetry

What Is C-Reactive Protein?

C-Reactive Protein (CRP) is a marker your body produces when it detects inflammation. It’s often checked alongside other tests to assess how your body is responding to injury, infection, or illness.

CRP is tested to monitor inflammation, track healing after surgery or trauma, evaluate autoimmune conditions, or check for signs of infection. It can also help guide treatment decisions.

Your doctor may order a CRP test if you have symptoms like fever, pain, swelling, or if you’re recovering from surgery, an injury, or a known inflammatory condition.

A blood sample is taken from a vein, usually in your arm. The sample is sent to a lab where it’s analyzed using a turbidimetric method to measure CRP levels.

CRP levels vary depending on health and medical history. Higher levels may indicate active inflammation, while lower levels suggest reduced inflammation. Your doctor will interpret results in the context of your symptoms and medical history.

CRP is commonly used to diagnose or monitor conditions like infections (e.g., pneumonia, appendicitis), autoimmune diseases (e.g., rheumatoid arthritis), or to assess risk for cardiovascular disease.

The frequency depends on your health needs. Some people get CRP tested once, while others may have it checked regularly if they have ongoing inflammation or a chronic condition.
