May aid in diagnosing acute infections and detecting past exposure and/or vaccination.
Semi-Quantitative Enzyme-Linked Immunosorbent Assay/Semi-Quantitative Chemiluminescent Immunoassay
Serum separator tube.
Separate serum from cells ASAP or within 2 hours of collection. Transfer 0.5 mL serum to an ARUP Standard Transport Tube. (Min: 0.2 mL) Parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens. Mark specimens plainly as "acute" or "convalescent."
See individual components.
After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
|0050167||Varicella-Zoster Virus Antibody, IgG||Effective February 18, 2020
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.
|0099314||Varicella-Zoster Virus Antibody, IgM||0.90 ISR or less: Negative - No significant level of detectable varicella-zoster virus IgM antibody.
0.91-1.09 ISR: Equivocal - Repeat testing in 10-14 days may be helpful.
1.10 ISR or greater: Positive - Significant level of detectable varicella-zoster virus IgM antibody. Indicative of current or recent infection. However, low levels of IgM antibodies may occasionally persist for more than 12 months post-infection or immunization.
