Test Code HSCRP C-Reactive Protein, High Sensitivity LAB150
Test Method
Near Infrared Particle Immunoassay Rate; Beckman
DXC600
Specimen Requirement
0.5 mL of serum or plasma is required.
Additional Specimen Collection Information
Collect blood in a lithium heparin, green-top or red-top
tube.
PST and SST (gel tubes) are acceptable. Serum or plasma should
be
separated from contact with the cells within 2 hours of
collection.
Specimens not centrifuged within 4 hours of collection may be
rejected. Refrigerate the specimen if unable to assay within 8
hours of collection.
Reference Values
Cardiovascular Risk Classification:
- Low Risk: < 1.0 mg/L
- Average Risk: 1.0-3.0 mg/L
- High Risk: > 3.0 mg/L
Performance
Testing is performed Monday through Sunday.
Routine: Typically completed within 4 hours after the
specimen
arrives at the testing site.
Expedite: Typically completed within 1.5 hours after
the
specimen arrives at the testing site.
STAT: Typically completed within 1 hour after the
specimen
arrives at the testing site.
Useful For
Measuring of very low levels of CRP (i.e. “normal
range” CRP) to stratify asymptomatic patients for
cardiovascular risk only. These low levels are not predictive
of
other systemic inflammatory conditions usually associated with
elevated CRP or sedimentation rate.
