Main Line Health Laboratories offers two different tests that measure
the same molecule in serum—C-Reactive Protein (CRP) and high-sensitivity
C-Reactive Protein (hs-CRP). These tests have very different clinical
indications (ICD-9 codes), methods of reporting and interpretation, CPT
codes, and reimbursement rates. Please be sure to choose the correct
test that is desired:
C-Reactive Protein (CPT code 86140) has been used for decades as
a measure of inflammation (acute phase reactant), somewhat
analogous to Erythrocyte Sedimentation Rate. Results are
presented with a reference (normal) range; abnormal values are
increased out of the normal range. Please order as “CRP”. The
results for this test have been placed in the general chemistry
section in SmartChart.
High sensitivity C-Reactive Protein (CPT code 86141) is a test
developed in the last few years as a measure of cardiovascular
risk. As the name implies, hs-CRP is more sensitive than the
older CRP test, based on the finding that even “normal” levels
of C-Reactive Protein may indicate increased risk of
cardiovascular events if the levels are at the higher end of the
normal range, presumably reflecting low-level inflammation that
contributes to progression of atherosclerosis. Results for
hs-CRP are grouped into thirds (tertiles) within the normal
range, with the highest tertile indicating the most risk. Please
order as “hs-CRP”. The results for this test have been placed in
the cardiac marker section in SmartChart.
Please note that if a test is ordered as “CRP”, the older, less
sensitive test for inflammation will be reported that is not useful as a
cardiovascular risk marker.
