###Human: Is it possible for C-reactive protein level to raise from 6 to 15. 9 in 24 hours? ###Assistant: Hi. C-reactive protein (CRP) is a marker of infection and inflammation anywhere in the body. It takes at least six hours for CRP to raise in the blood, once the infection starts and it continues to raise up to 24 hours at least. Though there are no signs of infection clinically, that is, the child is well symptomatically, it is still possible that CRP raises. Inference: Consult a paediatrician online for further help -->
