C-reactive protein (CRP) with high-sensitivity measurement (serum/plasma)

Why hs-CRP Matters in Health Monitoring

High-sensitivity CRP (hs-CRP) is a blood test that detects small amounts of a protein called C-reactive protein. CRP is produced by your liver in response to inflammation, which can occur due to infections, injuries, or chronic conditions like arthritis or heart disease. This test is particularly useful because it can identify subtle, long-term inflammation that might not be obvious otherwise.

How the Test Works

Your blood sample is drawn and analyzed using a sensitive immunoassay method to measure CRP levels. The test is designed to pick up very low concentrations of CRP, which is why it’s called high-sensitivity.

Common Uses for hs-CRP

Doctors often use hs-CRP to assess risk for cardiovascular diseases, monitor chronic inflammatory conditions, or evaluate the effectiveness of treatments for conditions like rheumatoid arthritis or other autoimmune diseases.

What Normal Results Mean

While reference ranges can vary by lab, lower CRP levels generally indicate minimal inflammation. Elevated levels may signal inflammation or infection, prompting further investigation. Your doctor will interpret results in the context of your overall health and symptoms.
