Interpretive data
Adult only - values greater than or equal to 10 mg/L are consistent
with infection or inflammation.
Individuals with evidence of active infection, systemic
inflammatory processes, or trauma should not be tested until these
conditions have abated. When using HS CRP to assess cardiovascular
risk, two measurements should be taken, two weeks apart (averaging
results).
The CDC/AHA recommends HS CRP cut off points (tertiles) above
for CVD assessment.
