C Reactive Protein (CRP)
CRP is an acute-phase protein, increasing in response to inflammatory disorders. Compared to other methods, CRP testing is more sensitive, the increase occurs earlier and its levels become more rapidly normal after healing.
Reference Ranges
| Adults | < 5 mg/L |
| Newborn up to 3 weeks | < 4.1 mg/L |
| Infants and children | < 2.8 mg/L |
Each laboratory should check if the reference ranges are transferable to its own patient population and determine own reference ranges if necessary. For diagnostic purposes, the results should always be assessed with the patient’s medical history, clinical examinations and other findings.
