C-Reactive Protein (CRP)
- Sample Type
- Standard
- Fasting
- No
- Unit
- mg/L
C-Reactive Protein (CRP) is an acute-phase reactant synthesized by the liver in response to interleukin-6. In an Arthritis Basic Screen, CRP is a non-specific but sensitive marker for systemic inflammation. It is used to distinguish inflammatory arthritides (like Rheumatoid Arthritis) from non-inflammatory conditions (like Osteoarthritis) and to monitor the therapeutic response to anti-inflammatory or biological agents.

Why Context Matters
CRP levels are highly non-specific and can be elevated by obesity, smoking, minor injuries, or recent infections unrelated to joint disease. Conversely, some individuals with active autoimmune disease may not show significant CRP elevation due to genetic variations or localized inflammation.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
