Test Information
Test Information
For assessing inflammation - NOT coronary risk. For assessing coronary risk, order C-Reactive Protein, High Sensitivity. CSF is not an appropriate specimen, as this test is not sensitive enough to concentrations of CRP found in CSF (approx. 10-fold lower than serum concentrations).
