Determine seroreactivity of women of childbearing age or provide evidence of vaccination/past infection.
Semi-quantitative Chemiluminescent Immunoassay
Within 24 hours
New York DOH Approval Status
Serum Separator Tube (SST).
Allow specimen to clot completely at room temperature. Separate from cells ASAP or within 2 hours of collection. Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.5 mL) Parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens.
Contaminated, heat-inactivated, or grossly hemolyzed specimens.
Label specimens plainly as "acute" or "convalescent."
After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (Avoid repeated freeze/thaw cycles)
|Less than 9 IU/mL:||Not Detected.|
|9-9.9 IU/mL:||Indeterminate - Repeat testing in 10-14 days may be helpful.|
|10 IU/mL or greater:||Detected.|
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.
The magnitude of the measured result is not indicative of the amount of antibody present.
