Which inflammatory markers are known to rise by up to about 1000-fold in inflammation?

• A. CRP and ESR
• B. CRP and SAA
• C. SAA and ESR
• D. CRP and Procalcitonin

Answer: (B)

When inflammation kicks in, the body ramps up production of acute-phase proteins in the liver, and some of these rise far more than others. C-reactive protein and serum amyloid A are two of the most dramatically increased markers. They can surge up to about 1000-fold above baseline in acute inflammatory states, making them highly sensitive indicators of inflammation and useful for tracking its course or response to treatment. ESR is also elevated with inflammation, but its rise is less directly tied to such extreme magnitudes and can be influenced by other factors, so it’s not described as reaching 1000-fold in most contexts. Procalcitonin tends to rise with bacterial infections but typically doesn’t achieve the same level of dramatic increase as CRP and SAA. So, the combination that best reflects that extreme, up-to-thousand-fold increase in inflammation is C-reactive protein and serum amyloid A.
