CRP and bacterial arthritis: Some data provide evidence on CRP and discitis, and it was also proposed as a negative predictor of septic arthritis, in which a study found that with values < 10 mg/L, it is not as likely for one to have the condition, but another study provided contrasted evidence, concluding that CRP < 10 mg/L cannot exclude the diagnosis of septic arthritis [977,978,979,980,981].
