|Description||An acute phase protein synthesised in the liver.|
|Indication||Detection and monitoring of inflammatory disease. Distinguishing between bacterial and viral infections.
|Additional Info||A normal CRP does not rule out inflammatory disease. A greater increase in CRP is seen with rheumatoid arthritis, vasculitis, trauma and certain malignant conditions. Less change occurs with ulcerative colitis, SLR, viral illness and osteoarthritis. Bacterial versus viral : A CRP >100 mg/L is suggestive of bacterial infection. In children with suspected meningitis a CRP >25mg/L is indicative of bacterial meningitis.
|Interpretation||An increase to 10 - 40mg/L can occur with mild inflammatory or viral infections. In acute or significant inflammation or bacterial infections CRP >40 mg/L.
|Tube||Serum or Heparin|
|Collection Conditions||Use Gold top (serum gel) tube except for Intensive care units, renal unit, transplant unit, patients on IV heparin (use Green/Yellow top tube for these patients).|
