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 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, grossly hemolyzed, lipemic, or severely icteric 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)

134.9 IV or less: Negative - No significant level of detectable varicella-zoster IgG antibody.
135.0-164.9 IV: Equivocal - Repeat testing in 10-14 days may be helpful.
165.0 IV or greater: Positive - IgG antibody to varicella-zoster detected, which may indicate a current or past varicella-zoster infection.
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.
For CSF specimens, refer to Varicella-Zoster Virus Antibody, IgG, CSF (ARUP test code 0054444).
