Table 3 Statement from the US Centers for Disease Control and Prevention/American Heart Association (CDC/AHA) on the measurement of C‐reactive protein, 20033.

1. hsCRP assay is the assay of choice and should be performed in metabolically stable persons without obvious inflammatory or infectious diseases
2. The results should be expressed in mg/litre and two assays, averaged, fasting or non‐fasting, 2 weeks apart (in this way, they represent the inflammatory status better)
3. The adult population should be stratified in three tertiles, at different cardiovascular risk
4. Subjects at the highest tertile have about a twofold increased risk of future cardiovascular disease compared with those in the lower tertile
5. Subjects with moderate risk (10–20% risk of CHD over 10 years) may benefit from measurement of CRP in addition to traditional cardiovascular risk factors

CHD, coronary heart disease; hsCRP: high sensitivity C‐reactive protein.
