CRP and infection: A study concluded that moderate CRP elevations (<100 mg/L) are common in both cases with contaminated blood cultures and in those with bacteremia, and if the CRP concentration is > 100 mg/L while eliminating other causes of marked CRP increases, CRP may be a relatively specific indicator of infection; However, CRP increases are neither completely sensitive nor to detect infection in bacteremia patients, yet the CRP level in Staphylococcus aureus bacteremia cases can be affected by certain SNPs [898].
