| Order Code: | HAPT |
| Order Form: | Laboratory Requisition |
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 green top tube or ONE microtainer
Testing
Schedule:
24 hrs/day, 7 days a week, including holidays.
Analytic Time:
1 hour (upon receipt in laboratory)
Reference Range:
30-200 mg/dL
Test
Limitations:
Rheumatoid factors less than 100 IU/mL do not interfere.
A high-dose hook effect may occur at haptoglobin concentrations above 1200 mg/dL.
Hemolysis: No significant interference up to an H index of 1000 (approximate hemoglobin concentration: 1000 mg/dL).
Lipemia: No significant interference up to an L index of 1000 (approximate triglycerides concentration: 2000 mg/dL). Note there is poor correlation between turbidity and triglyceride concentration.
Icterus: No significant interference up to an I index of 60 (approximate conjugated and unconjugated bilirubin concentration: 60 mg/dL).
