Intended Use

CRP is an acute phase reactant, which can be used as a test
for inflammatory diseases, infections, and neoplastic diseases.
Progressive increases correlate with increases of inflammation/injury. CRP
is a more sensitive, rapidly responding indicator than ESR. CRP may be
used to detect early postoperative wound infection and to follow
therapeutic response to anti-inflammatory agents. High sensitive version
of the CRP assay may be used as an additional indicator for susceptibility
to cardiac disease (test code 407).

Limitations

CRP arises as a nonspecific response to tissue injury and
inflammation. In rare cases of gammopathy, may cause unreliable results.
Results should not be interpreted without a complete clinical
history.

Measuring range: 0.3 to 350
