Detect prior exposure to T. gondii.
Semi-quantitative Chemiluminescent Immunoassay
Within 24 hours
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)
Effective March 3, 2014
|7.1 IU/mL or less:||Not Detected.|
|7.2-8.7 IU/mL:||Indeterminate - Repeat testing in 10-14 days may be helpful.|
|8.8 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.
This test should not be used for blood donor screening, associated re-entry protocols, or for screening Human Cell, Tissues and Cellular and Tissue-Based Products (HCT/P).
