C-reactive protein is which type of acute phase protein?

• A. Negative
• B. Positive
• C. Neutral
• D. Decreasing

Answer: (B)

Inflammation triggers the liver to change the production of acute-phase proteins, with some rising and others falling. C-reactive protein is a classic positive acute-phase protein because its synthesis increases in response to inflammatory cytokines, especially IL-6. This rise happens quickly and can be substantial, making CRP a useful marker of inflammation. Negative acute-phase proteins, like albumin, decrease during inflammation, and neutral proteins don’t change significantly. Since CRP increases rather than stays the same or decreases, the correct description is that it is a positive acute-phase protein.
