CRP is an acute-phase protein produced by the liver in response to inflammation.

The qualitative test determines whether CRP is present (positive) or absent (negative), without measuring exact concentration.

Clinical uses include:

Detecting acute infections and inflammatory conditions.

Supporting diagnosis of autoimmune diseases (e.g., rheumatoid arthritis, lupus).

Monitoring post-surgical complications or inflammatory responses.

The test is performed using a blood sample, often via latex agglutination or rapid immunoassay methods.

Analyte: C-Reactive Protein (CRP) in blood serum.

Normal Result: Negative (no CRP detected).

Positive Result: Presence of CRP → indicates inflammation or infection.

Clinical Use:

Detects inflammatory activity in the body.

Helps differentiate between bacterial and viral infections (when combined with other tests).

Guides further diagnostic evaluation and treatment monitoring.
