What a high CRP (C Reactive Protein) Quantitative means, and common causes

C-reactive protein rises within hours of inflammation starting, so a high value means something active is going on right now. It does not say where.

Common causes: Bacterial infection, which typically pushes it much higher than a viral one, autoimmune flare, injury or surgery, and any acute inflammation.

What a low CRP (C Reactive Protein) Quantitative means, and common causes

A low CRP is the normal, healthy result.

Common causes: Nothing. A low value simply means no significant active inflammation.

Frequently asked questions

Usually under 5 or 6 mg/L, depending on the lab.

CRP rises and falls within hours, so it tracks what is happening now. ESR moves over weeks and is better for following a long-standing condition.

Sharir mein kahin sujan ya infection active hai. Kahan hai yeh test nahin batata, iske liye doctor doosri jaanch karte hain.
