Working in the ED one day you seem to hit a run of patients in whom consultants have asked you to order an ESR, CRP.  First, podiatry asked for them for a patient with 1st metatarsal osteomyelitis.  Spine surgery wanted the same for a patient with diskitis. And, ortho wanted them for a possible septic.  You think to yourself, “what am I or my consultant going to do with these test results?” “What are these inflammatory markers anyhow?” And, “what patient’s should I be ordering them in.”
