A CRP blood test result of 34.5 is significantly high. Test results greater than 10 mg/L are normally a sign of a serious infection, trauma or disease, and likely require more extensive testing to root the exact cause, according to Mayo Clinic.
C-reactive protein tests are performed to check for inflammation or infection indicative of chronic inflammatory diseases such as lupus, rheumatoid arthritis or risk of heart disease. Patients with CRP levels less than 1.0 mg/L are at low-risk for heart disease, those with levels from 1.0 to 3.0 are at average risk. Since CRP levels vary over time, the average of two tests are often used to determine chance, cites Mayo Clinic.
