Rubella Antibody, IgG
| Order Code: | RUBEIGG |
Specimen:
Plasma
Collection Medium:
 |
| Plasma Separator Tube |
Minimum:
3 mL whole blood in light green top tube or TWO microtainers.
Rejection Criteria:
Heat-inactivated, hemolyzed, or contaminated specimens.
Analytic Time:
1 hour (upon receipt in laboratory)
Reference Range:
Less than 5 IU/mL: Negative - No significant level of detectable
rubella IgG antibody.
5-9 IU/mL: Equivocal - Repeat testing in 10-14 days may be helpful.
10 IU/mL or greater: Positive - IgG antibody to rubella detected,
which may indicate a current or
previous exposure/immunization to
rubella.
Interpretive Data:
The best evidence for current infection is a significant change on two
appropriately timed specimens, where both tests are done in the same
laboratory at the same time.
Test
Limitations:
Hemolysis: No significant interference up to an H index of 5600
(approximate hemoglobin concentration: 5600 mg/dL).
Lipemia: No significant interference up to an L index of 1500 (approximate triglycerides concentration: 3000 mg/dL). Note there is poor correlation between turbidity and triglyceride concentration.
Icterus: No significant interference up to an I index of 30 (approximate conjugated and unconjugated bilirubin concentration: 30 mg/dL).
Lipemia: No significant interference up to an L index of 1500 (approximate triglycerides concentration: 3000 mg/dL). Note there is poor correlation between turbidity and triglyceride concentration.
Icterus: No significant interference up to an I index of 30 (approximate conjugated and unconjugated bilirubin concentration: 30 mg/dL).
Methodology:
