Increased C-reactive protein indicates what?

• A. Dehydration
• B. Infection
• C. Anemia
• D. Hyperglycemia

Answer: (B)

Elevated C-reactive protein signals inflammation in the body. CRP is produced by the liver in response to inflammatory signals, and its level rises quickly when there’s acute inflammation, such as from an infection, tissue injury, or autoimmune activity. It’s a nonspecific marker, meaning it confirms that inflammation is present but doesn’t identify the exact cause. Among the options, infection best fits because infections commonly trigger an inflammatory response that raises CRP. Dehydration itself doesn’t typically raise CRP, and anemia or hyperglycemia are metabolic conditions not directly responsible for a CRP rise. Clinically, CRP helps gauge the presence and intensity of inflammation and track how well the inflammation is responding to treatment.
