CRP (C-Reactive Protein)
CRP stands for C-Reactive Protein, which is a protein produced by the liver that functions as a key marker of inflammation and infection in the body.
It is one of the body's acute phase reactants—a group of substances whose concentration in the blood increases rapidly (within hours) in response to any tissue injury, infection, or severe inflammation.
Why Do You Need This Test?
The standard CRP test is a crucial, non-specific marker used in conjunction with other clinical findings to:
- Detect Active Infection: A very high CRP level strongly suggests the presence of a significant bacterial or viral infection.
- Monitor Inflammatory Diseases: Assessing the activity level of chronic inflammatory conditions, such as Rheumatoid Arthritis, Lupus, or Inflammatory Bowel Disease (IBD).
- Guide Antibiotic Treatment: Tracking a patient's response to treatment; CRP levels should drop rapidly if an infection is responding to antibiotics.
