C-Reactive Protein (CRP)
| Order Code: | CRP |
| Epic Lab Code: | LAB149 |
| Order Form: | A-1a General Lab or Epic Req |
Chemistry
6240 RCP
356-3527

Specimen:
Plasma
Collection Medium:
![]() |
| Plasma Separator Tube |
Alternate
Collection Media:
Call laboratory for additional acceptable specimen collection containers.
Minimum:
3 mL whole blood from light gr een top tube or 1 light green
microtainer for pediatric patients
Testing Schedule:
24 hrs/day, 7 days a week, including holidays.
Analytic Time:
1 hour (upon receipt in laboratory)
Reference Range:
<0.5 mg/dL
Test
Limitations:
Criterion: Recovery within plus or minus 10% of initial values.
Icterus: No significant interference up to an I index of 60
(approximate conjugated and unconjugated bilirubin concentration: 60
mg/dL or 1026 umol/l).
Hemolysis: No significant interference up to an H index of 1000.
(approximate hemoglobin concentration: 700 mg/dL or 435 umol/l )
Lipemia (Intralipid): No significant interference up to an L index of
1000 (approximate triglyceride concentration: 2000 mg/dL or 22.8
mmol/l).
There is poor correlation between turbidity and triglyceride
concentration.
Rheumatoid factors less than 1200 IU/mL do not interfere.
A high-dose hook effect may occur at CRP concentrations greater than 50
mg/dL.
Significantly decreased CRP values may be obtained from samples taken
from patients who have been treated with carboxypenicillins.
Methodology:
Immunoturbidometric
CPT Code:
86140
